should conform to ANSI Z87. I standards.  
kill.  
3.a. The electrode and work (or ground) circuits  
are electrically “hot” when the welder is on.  
Do not touch these “hot” parts with your bare  
skin or wet clothing. Wear dry, hole-free  
gloves to insulate hands.  
4.b. Use suitable clothing made from durable flame-resistant  
material to protect your skin and that of your helpers from  
the arc rays.  
3.b. Insulate yourself from work and ground using dry insulation.  
Make certain the insulation is large enough to cover your full  
area of physical contact with work and ground.  
4.c. Protect other nearby personnel with suitable, non-flammable  
screening and/or warn them not to watch the arc nor expose  
themselves to the arc rays or to hot spatter or metal.  
In addition to the normal safety precautions, if welding  
must be performed under electrically hazardous  
conditions (in damp locations or while wearing wet  
clothing; on metal structures such as floors, gratings or  
scaffolds; when in cramped positions such as sitting,  
kneeling or lying, if there is a high risk of unavoidable or  
accidental contact with the workpiece or ground) use  
the following equipment:  
FUMES AND GASES  
can be dangerous.  
5.a. Welding may produce fumes and gases  
hazardous to health. Avoid breathing these

ventilation and/or exhaust at the arc to keep  
fumes and gases away from the breathing zone. When  
welding with electrodes which require special  
ventilation such as stainless or hard facing (see  
instructions on container or MSDS) or on lead or  
cadmium plated steel and other metals or coatings  
which produce highly toxic fumes, keep exposure as  
low as possible and below Threshold Limit Values (TLV)  
using local exhaust or mechanical ventilation. In  
confined spaces or in some circumstances, outdoors, a  
respirator may be required. Additional precautions are  
also required when welding on galvanized steel.  
3.c. In semiautomatic or automatic wire welding, the electrode,  
electrode reel, welding head, nozzle or semiautomatic  
welding gun are also electrically “hot”.  
3.d. Always be sure the work cable makes a good electrical  
connection with the metal being welded. The connection  
should be as close as possible to the area being welded.  
3.e. Ground the work or metal to be welded to a good electrical  
(earth) ground.  
5. b. The operation of welding fume control equipment is affected  
by various factors including proper use and positioning of  
the equipment, maintenance of the equipment and the spe-  
cific welding procedure and application involved. Worker  
exposure level should be checked upon installation and  
periodically thereafter to be certain it is within applicable  
OSHA PEL and ACGIH TLV limits.  
3.f. Maintain the electrode holder, work clamp, welding cable and  
welding machine in good, safe operating condition. Replace  
damaged insulation.  
3.g. Never dip the electrode in water for cooling.  
3.h. Never simultaneously touch electrically “hot” parts of  
electrode holders connected to two welders because voltage  
between the two can be the total of the open circuit voltage  
of both welders.  
5.c. Do not weld in locations near chlorinated hydrocarbon vapors  
coming from degreasing, cleaning or spraying operations.  
The heat and rays of the arc can react with solvent vapors to  
form phosgene, a highly toxic gas, and other irritating prod-  
ucts.  
3.i. When working above floor level, use a safety belt to protect  
yourself from a fall should you get a shock.  
5.d. Shielding gases used for arc welding can displace air and  
cause injury or death. Always use enough ventilation,  
especially in confined areas, to insure breathing air is safe.  
3.j. Also see Items 6.c. and 8.  
5.e. Read and understand the manufacturerʼs instructions for this  
equipment and the consumables to be used, including the  
material safety data sheet (MSDS) and follow your  
employerʼs safety practices. MSDS forms are available from  
your welding distributor or from the manufacturer.

pressure used. All hoses, fittings, etc. should be suitable for  
the application and maintained in good condition.  
7.b. Always keep cylinders in an upright position securely  
chained to an undercarriage or fixed support.  
6.b. Where compressed gases are to be used at the job site,  
special precautions should be used to prevent hazardous  
situations. Refer to “Safety in Welding and Cutting” (ANSI  
Standard Z49.1) and the operating information for the  
equipment being used.  
7.c. Cylinders should be located:  
•Away from areas where they may be struck or subjected to  
physical damage.  
•A safe distance from arc welding or cutting operations and  
any other source of heat, sparks, or flame.  
6.c. When not welding, make certain no part of the electrode  
circuit is touching the work or ground. Accidental contact  
can cause overheating and create a fire hazard.  
7.d. Never allow the electrode, electrode holder or any other  
electrically “hot” parts to touch a cylinder.  
6.d. Do not heat, cut or weld tanks, drums or containers until the  
proper steps have been taken to insure that such procedures  
will not cause flammable or toxic vapors from substances  
inside. They can cause an explosion even though they have  
been “cleaned”. For information, purchase “Recommended  
Safe Practices for the Preparation for Welding and Cutting of  
Containers and Piping That Have Held Hazardous  
Substances”, AWS F4.1 from the American Welding Society  
(see address above).  
7.e. Keep your head and face away from the cylinder valve outlet  
when opening the cylinder valve.  
7.f. Valve protection caps should always be in place and hand  
tight except when the cylinder is in use or connected for  
use.  
7.g. Read and follow the instructions on compressed gas  
cylinders, associated equipment, and CGA publication P-l,  
“Precautions for Safe Handling of Compressed Gases in  
Cylinders,” available from the Compressed Gas Association  
1235 Jefferson Davis Highway, Arlington, VA 22202.  
6.e. Vent hollow castings or containers before heating, cutting or  
welding. They may explode.  
6.f. Sparks and spatter are thrown from the welding arc. Wear oil  
free protective garments such as leather gloves, heavy shirt,  
cuffless trousers, high shoes and a cap over your hair. Wear  
ear plugs when welding out of position or in confined places.  
Always wear safety glasses with side shields when in a  
welding area.  
FOR ELECTRICALLY  
powered equipment.  
8.a. Turn off input power using the disconnect  
switch at the fuse box before working on  
the equipment.  
6.g. Connect the work cable to the work as close to the welding  
area as practical. Work cables connected to the building  
framework or other locations away from the welding area  
increase the possibility of the welding current passing  
through lifting chains, crane cables or other alternate cir-  
cuits. This can create fire hazards or overheat lifting chains  
or cables until they fail.  
8.b. Install equipment in accordance with the U.S. National  
Electrical Code, all local codes and the manufacturerʼs  
recommendations.  
8.c. Ground the equipment in accordance with the U.S. National  
Electrical Code and the manufacturerʼs recommendations.

SAFETY  
5. Toujours porter des lunettes de sécurité dans la zone de  
soudage. Utiliser des lunettes avec écrans lateraux dans les  
zones où lʼon pique le laitier.  
PRÉCAUTIONS DE SÛRETÉ  
Pour votre propre protection lire et observer toutes les instructions  
et les précautions de sûreté specifiques qui parraissent dans ce  
manuel aussi bien que les précautions de sûreté générales suiv-  
antes:  
6. Eloigner les matériaux inflammables ou les recouvrir afin de  
prévenir tout risque dʼincendie dû aux étincelles.  
7. Quand on ne soude pas, poser la pince à une endroit isolé de  
la masse. Un court-circuit accidental peut provoquer un  
échauffement et un risque dʼincendie.  
Sûreté Pour Soudage A LʼArc  
1. Protegez-vous contre la secousse électrique:  
a. Les circuits à lʼélectrode et à la piéce sont sous tension  
quand la machine à souder est en marche. Eviter toujours  
tout contact entre les parties sous tension et la peau nue  
ou les vétements mouillés. Porter des gants secs et sans  
trous pour isoler les mains.  
b. Faire trés attention de bien sʼisoler de la masse quand on  
soude dans des endroits humides, ou sur un plancher  
metallique ou des grilles metalliques, principalement dans  
les positions assis ou couché pour lesquelles une grande  
partie du corps peut être en contact avec la masse.  
c. Maintenir le porte-électrode, la pince de masse, le câble  
de soudage et la machine à souder en bon et sûr état  
defonctionnement.  
d.Ne jamais plonger le porte-électrode dans lʼeau pour le  
refroidir.  
e. Ne jamais toucher simultanément les parties sous tension  
des porte-électrodes connectés à deux machines à souder  
parce que la tension entre les deux pinces peut être le  
total de la tension à vide des deux machines.  
f. Si on utilise la machine à souder comme une source de  
courant pour soudage semi-automatique, ces precautions  
pour le porte-électrode sʼapplicuent aussi au pistolet de  
soudage.  
8. Sʼassurer que la masse est connectée le plus prés possible  
de la zone de travail quʼil est pratique de le faire. Si on place  
la masse sur la charpente de la construction ou dʼautres  
endroits éloignés de la zone de travail, on augmente le risque  
de voir passer le courant de soudage par les chaines de lev-  
age, câbles de grue, ou autres circuits. Cela peut provoquer  
des risques dʼincendie ou dʼechauffement des chaines et des  
câbles jusquʼà ce quʼils se rompent.  
9. Assurer une ventilation suffisante dans la zone de soudage.  
Ceci est particuliérement important pour le soudage de tôles  
galvanisées plombées, ou cadmiées ou tout autre métal qui  
produit des fumeés toxiques.  
10. Ne pas souder en présence de vapeurs de chlore provenant  
dʼopérations de dégraissage, nettoyage ou pistolage. La  
chaleur ou les rayons de lʼarc peuvent réagir avec les vapeurs  
du solvant pour produire du phosgéne (gas fortement toxique)  
ou autres produits irritants.  
11. Pour obtenir de plus amples renseignements sur la sûreté,  
voir le code “Code for safety in welding and cutting” CSA  
Standard W 117.2-1974.  
2. Dans le cas de travail au dessus du niveau du sol, se protéger  
contre les chutes dans le cas ou on recoit un choc. Ne jamais  
enrouler le câble-électrode autour de nʼimporte quelle partie  
du corps.  
PRÉCAUTIONS DE SÛRETÉ POUR  
LES MACHINES À SOUDER À  
TRANSFORMATEUR ET À  
REDRESSEUR  
3. Un coup dʼarc peut être plus sévère quʼun coup de soliel,  
donc:  
a. Utiliser un bon masque avec un verre filtrant approprié  
ainsi quʼun verre blanc afin de se protéger les yeux du ray-  
onnement de lʼarc et des projections quand on soude ou  
quand on regarde lʼarc.  
b. Porter des vêtements convenables afin de protéger la  
peau de soudeur et des aides contre le rayonnement de  
lʻarc.  
c. Protéger lʼautre personnel travaillant à proximité au  
soudage à lʼaide dʼécrans appropriés et non-inflammables.  
1. Relier à la terre le chassis du poste conformement au code de  
lʼélectricité et aux recommendations du fabricant. Le dispositif  
de montage ou la piece à souder doit être branché à une  
bonne mise à la terre.  
2. Autant que possible, Iʼinstallation et lʼentretien du poste seront  
effectués par un électricien qualifié.  
4. Des gouttes de laitier en fusion sont émises de lʼarc de  
soudage. Se protéger avec des vêtements de protection libres  
de lʼhuile, tels que les gants en cuir, chemise épaisse, pan-  
talons sans revers, et chaussures montantes.  
3. Avant de faires des travaux à lʼinterieur de poste, la debranch-  
er à lʼinterrupteur à la boite de fusibles.  
4. Garder tous les couvercles et dispositifs de sûreté à leur  
place.

ELECTRIC SHOCK can kill.  
If the engine is to be operated at an angle, provisions must be  
made for checking and maintaining the oil level at the normal  
(FULL) oil capacity in the crankcase.  
• Do not touch electrically live parts or  
electrode with skin or wet clothing.  
• Insulate yourself from work and ground  
• Always wear dry insulating gloves.  
When operating the welder at an angle, the effective fuel  
capacity will be slightly less than the amount specified.

ENGINE EXHAUST can kill.  
• Use in open, well ventilated areas or vent  
exhaust outside.  
MACHINE GROUNDING  
------------------------------------------------------------------------  
MOVING PARTS can injure.  
According to the United States National Electrical Code, the  
frame of this portable generator is not required to be grounded  
and is permitted to serve as the grounding means for cord  
connected equipment plugged into its receptacle.  
• Do not operate with doors open or guards  
off.  
• Stop engine before servicing.  
• Keep away from moving parts.  
------------------------------------------------------------------------  
See additional warning information at the front  
Some state, local, or other codes or unusual operating circum-  
stances may require the machine frame to be grounded. It is  
recommended that you determine the extent to which such  
requirements may apply to your particular situation and follow  
them explicitly. A machine grounding stud marked with the  
of this operatorʼs manual.

EXHAUST SPARK ARRESTER  
symbol  
is provided on the welding generator frame foot. In  
Some federal, state or local laws may require that engines  
be equipped with exhaust spark arresters when they are  
operated in certain locations where unarrested sparks may  
present a fire hazard. The standard muffler included with  
this welder does not qualify as a spark arrester. When  
required by local regulations, a suitable spark arrester must  
be installed and properly maintained.  
general, if the machine is to be grounded, it should be con-  
nected with a #8 or larger copper wire to a solid earth ground  
such as a metal water pipe going into the ground for at least  
ten feet and having no insulated joints, or to the metal frame-  
work of a building which has been effectively grounded. The  
U.S. National Code lists a number of alternate means of  
grounding electrical equipment.  
LIFT BAIL  
CAUTION  
A lift bail is provided for lifting with a hoist.  
Use of an incorrect arrester may lead to engine damage or  
performance loss. Contact the engine manufacturer for spe-  
cific recommendations.

WARNING  
LOCATION/VENTILATION  
Always operate the welder with the doors closed. Leaving the  
doors open changes the designed air flow and may cause  
overheating.  
• Lift only with equipment of  
adequate lifting capacity.  
• Be sure machine is stable  
when lifting.  
The welder should be located to provide an unrestricted flow  
of clean, cool air. Also, locate the welder so that engine

STOPPING THE ENGINE  
front of this operatorʼs manual.  
1. Turn the “IGNITION” switch to “OFF”  
Operate the welder with the doors closed. Leaving the  
doors open changes the designed air flow and can  
cause overheating.  
At the end of each dayʼs welding, check the crankcase  
oil level, drain accumulated dirt and water from the  
water separator and refill the fuel tank to minimize  
moisture condensation in the tank. Also, running out  
of fuel tends to draw dirt into the fuel system.  
STARTING THE CLASSIC 300D KUBOTA V2203M  
DIESEL ENGINE  
When hauling the welder between job sites, close the  
valve on the water separator.  
1. Turn the “IDLER” switch to “HIGH”.  
2. Turn the “IGNITION” switch to “ON”.  
3. Press the Glow Plug button for 20 to 30 seconds.  
(maximum 60 seconds).  
If the fuel supply is cut off or runs out while the fuel  
pump is operating, air may be entrapped in the fuel  
distribution system. If this happens, bleeding of the  
fuel system may be necessary. Use qualified person-  
nel to do this per the instructions in the MAINTE-  
NANCE section of this manual.  
4. Press the Glow Plug button and the Start button at the  
same time. When the engine starts running, release  
both buttons. If the engine fails to start in 20 seconds,  
wait 30 seconds and repeat the above procedure.  
5. Observe the oil pressure. If no pressure shows within  
30 seconds, stop the engine and consult the engine  
operating manual. To stop the engine, turn the “IGNI-  
TION” switch to “OFF”.  
ENGINE BREAK-IN  
6. If the engine protection warning light comes on during  
cranking or after start up, the “IGNITION” switch must  
be turned “OFF” to reset the engine protection system.  
7. Allow the engine to run at high idle speed for several  
minutes to warm the engine. Stop the engine and  
recheck the oil level, after allowing sufficient time for  
the oil to drain into the pan. If the level is down, fill it to  
the full mark again. The engine controls were properly  
set at the factory and should require no adjusting when  
received.  
Lincoln Electric selects high quality, heavy-duty indus-  
trial engines for the portable welding machines we  
offer. While it is normal to see a small amount of  
crankcase oil consumption during initial operation,  
excessive oil use, wet stacking (oil or tar like sub-  
stance at the exhaust port), or excessive smoke is not  
normal.

OPERATION  
DUTY CYCLE  
Larger machines with a capacity of 350 amperes and  
higher, which are operated at low or no-load condi-  
tions for extended periods of time are especially sus-  
ceptible to the conditions described above. To  
accomplish successful engine break-in, most diesel-  
powered equipment needs only to be run at a reason-  
ably heavy load within the rating of the welder for  
some period of time during the engineʼs early life.  
However, if the welder is subjected to extensive light  
loading, occasional moderate to heavy loading of the  
engine may sometimes be necessary. Caution must  
be observed in correctly loading a diesel/generator  
unit.  
The NEMA output rating of the CLASSIC 300D KUB-  
OTA is 300 amperes at 32 arc volts on a 60% duty  
cycle (consult Specifications in this manual for alter-  
nate ratings). Duty cycle is based on a ten minute  
period; thus, the welder can be loaded at rated output  
for six minutes out of every ten minute period.  
CONTROL OF WELDING CURRENT  
CAUTION  
DO NOT TURN THE “CURRENT RANGE SELEC-  
TOR” WHILE WELDING because the current may  
arc between the contacts and damage the switch.  
------------------------------------------------------------------------  
1. Connect the welder output studs to a suitable  
resistive load bank. Note that any attempt to  
short the output studs by connecting the welding  
leads together, direct shorting of the output studs,  
or connecting the output leads to a length of steel  
will result in catastrophic damage to the generator  
and voids the warranty.  
The “Current Range Selector” provides five overlap-  
ping current ranges. The “Fine Current Adjustment”  
adjusts the current from minimum to maximum within  
each range. Open circuit voltage is also controlled by  
the “Fine Current Adjustment” permitting control of the  
arc characteristics.  
2. Set the welder controls for an output current and  
voltage within the welder rating and duty cycle.  
Note that any attempt to exceed the welder rating  
or duty cycle for any period of time will result in  
catastrophic damage to the generator and voids  
the warranty.  
A high open circuit voltage setting provides the soft  
“buttering” arc with best resistance to pop-outs pre-  
ferred for most welding. To get this characteristic, set  
the “Current Range Selector” to the lowest setting that  
still provides the current you need and set the “Fine  
Current Adjustment” near maximum. For example: to  
obtain 175 amps and a soft arc, set the “Current

crankcase oil level.  
WELDER OPERATION  
WARNING  
Range Selector” to the 190-120 position and then  
adjust the “Fine Current Adjustment” for 175 amps.  
ELECTRIC SHOCK can kill.  
When a forceful “digging” arc is required, usually for  
vertical and overhead welding, use a higher “Current  
Range Selector” setting and lower open circuit volt-  
age. For example: to obtain 175 amps and a forceful  
arc, set the “Current Range Selector” to the 240-160  
position and the “Fine Current Adjustment” setting to  
get 175 amps.  
• Do not touch electrically live parts or  
electrode with skin or wet clothing.  
• Insulate yourself from work and ground.  
FUMES & GASES can be dangerous.  
• Keep your head out of the fumes.  
• Use ventilation or exhaust to remove  
fumes from breathing zone.  
Some arc instability may be experienced with EXX10  
electrodes when trying to operate with long arc tech-  
niques at settings at the lower end of the open circuit  
voltage range.  
WELDING SPARKS can cause fire or  
explosion.  
• Keep flammable material away.  
CAUTION  
DO NOT attempt to set the “Current Range Selector”  
between the five points designated on the nameplate.  
------------------------------------------------------------------------  
ARC RAYS can burn.  
• Wear eye, ear, and body protection.  
------------------------------------------------------------------------  
These switches have a spring loaded cam which  
almost eliminates the possibility of setting this switch  
between the designated points.

OPERATION  
IDLER OPERATION  
The AC auxiliary power, supplied as a standard, has a  
rating of 3.0 kVA of 115/230 VAC (60 hertz).  
Start the engine with the “Idler” switch in the “High”  
position. Allow it to run at high idle speed for several  
minutes to warm the engine. See Specifications for  
operating speeds.  
With the 3.0 kVA, 115/230 VAC auxiliary power, one  
115V duplex and one 230V duplex, grounding type  
receptacle are provided. The circuit is protected with  
circuit breakers.  
The idler is controlled by the “Idler” toggle switch on  
the welder control panel. The switch has two posi-  
tions as follows:  
The rating of 3.0 kVA permits a maximum continuous  
current of 13 amps to be drawn from the 230 volt  
duplex receptacle. Or a total of 26 amps can be drawn  
from the 115 volt duplex receptacle. The 115 volt  
duplex receptacle has a configuration which permits  
20 amps to be drawn from either half. The total com-  
bined load of all receptacles is not to exceed 3.0 kVA.  
1. In the “High”  
position, the engine control unit  
increases the engine to high idle speed.  
2. In the “Auto”  
/
position, the idler oper-  
ates as follows:  
An optional power plug kit is available. When this kit is  
specified, the customer is supplied with a plug for  
each receptacle.  
a. When welding or drawing power for lights or tools  
(approximately 100 watts minimum) from the recep-  
tacles, the engine operates at high idle speed.  
When the High Speed Adjustment knob is in the MIN  
position, the frequency of the AC auxiliary output may  
be reduced to approximately 55 Hertz. It is recom-  
mended that the High Idle Speed Adjustment knob  
should be in the MAX position when using the AC  
auxiliary output.  
b. When welding ceases or the power load is turned  
off, a preset time delay of about 15 seconds starts.  
This time delay cannot be adjusted.  
c. If the welding or power load is not re-started before  
the end of the time delay, the engine control unit  
reduces the engine to low idle speed.  
AUXILIARY POWER  
Start the engine and set the “IDLER” control switch to  
the “High Idle” mode. Voltage is now correct at the  
receptacles for auxiliary power. This must be done  
before a tripped GFCI receptacle can be reset proper-  
ly. See the MAINTENANCE section for detailed infor-  
mation on testing and resetting the GFCI receptacle.

MAINTENANCE  
MAINTENANCE  
4.  
Follow the engine service schedule in this manual  
and the detailed maintenance and troubleshooting in  
the engine manufacturerʼs manual.  
WARNING  
Have qualified personnel do the maintenance  
work. Turn the engine off before working inside  
the machine. In some cases, it may be neces-  
sary to remove safety guards to perform  
required maintenance. Remove guards only  
when necessary and replace them when the  
maintenance requiring their removal is com-  
plete. Always use the greatest care when work-  
ing near moving parts.  
COOLING SYSTEM  
The CLASSIC 300D KUBOTA is equipped with a  
pressure radiator. Keep the radiator cap tight to pre-  
vent loss of coolant. Clean and flush the cooling sys-  
tem periodically to prevent clogging the passage and  
overheating the engine. When antifreeze is needed,  
always use the permanent type.  
BEARINGS  
Do not put your hands near the engine cooling  
blower fan. If a problem cannot be corrected by  
following the instructions, take the machine to  
the nearest Lincoln Field Service Shop.  
This welder is equipped with a double-shielded ball  
bearing having sufficient grease to last indefinitely  
under normal service. Where the welder is used con-  
stantly or in excessively dirty locations, it may be nec-  
essary to add one half ounce of grease per year. A  
pad of grease one inch wide, one inch long, and one  
inch high weighs approximately one half ounce. Over-  
greasing is far worse than insufficient greasing.  
-----------------------------------------------------------------------  
ELECTRIC SHOCK can kill.  
• Do not touch electrically live parts or  
electrode with skin or wet clothing.  
• Insulate yourself from work and  
ground  
• Always wear dry insulating gloves.  
When greasing the bearings, keep all dirt out of the  
area. Wipe the fittings completely clean and use clean  
equipment. More bearing failures are caused by dirt  
introduced during greasing than from insufficient  
grease.  
------------------------------------------------------------------------  
ENGINE EXHAUST can kill.  
• Use in open, well ventilated areas or  
vent exhaust outside.  
COMMUTATOR AND BRUSHES  
------------------------------------------------------------------------  
MOVING PARTS can injure.  
WARNING  
• Do not operate with doors open or  
guards off.  
Uncovered rotating equipment can be dangerous.  
Use care so your hands, hair, clothing or tools do  
not catch in the rotating parts. Protect yourself  
from particles that may be thrown out by the rotat-  
• Stop engine before servicing.  
• Keep away from moving parts.

front of this operatorʼs manual.  
------------------------------------------------------------------------  
-----------------------------------------------------------  
Shifting of the commutator brushes may result in:  
- Change in machine output  
- Commutator damage  
GENERAL INSTRUCTIONS  
- Excessive brush wear  
1. Blow out the welder and controls with an air hose at  
least once every two months. In particularly dirty  
locations, this cleaning may be necessary once a  
week. Use low pressure air to avoid driving dirt into  
the insulation.  
Periodically inspect the commutator, slip rings, and  
brushes by removing the covers. DO NOT remove or  
replace these covers while the machine is running.  
Commutators and slip rings require little attention.  
However, if they are black or appear uneven, have  
them cleaned by an experienced maintenance man  
using fine sandpaper or a commutator stone. Never  
use emery cloth or paper for this purpose.  
2. “Current Range Selector” contacts should not be  
greased. To keep the contacts clean, rotate the cur-  
rent control through its entire range frequently.  
Good practice is to turn the handle from maximum  
to minimum setting twice each morning before start-  
ing to weld.  
3. Put a drop of oil on the “Current Range Selector”  
shaft at least once every month.

MAINTENANCE  
Replace brushes when they wear within 1/4”(3.5mm)  
of the pigtail. A complete set of replacement brushes  
should be kept on hand. Lincoln brushes have a  
curved face to fit the commutator. Have an experi-  
enced maintenance man seat these brushes by lightly  
stoning the commutator as the armature rotates at full  
speed until contact is made across the full face of the  
brushes. After stoning, blow out the dust with low  
pressure air.  
PURGING AIR FROM FUEL SYSTEM  
(KUBOTA V2203M ENGINE)  
WARNING  
Keep fuel clear of open flames or arcs, allow  
engine to cool before working on the fuel system.  
Wipe up any spilled fuel and do not start engine  
until fumes clear.  
------------------------------------------------------------------------  
If the engine is running rough and you suspect air has  
been trapped in the fuel system, (e.g. the engine was  
allowed to run out of fuel) perform the following steps  
using qualified personnel:  
To seat slip ring brushes, position the brushes in  
place. Then slide one end of a piece of fine sandpaper  
between slip rings and brushes with the coarse side  
against the brushes. With slight additional finger pres-  
sure on top of the brushes, pull the sandpaper around  
the circumference of the rings - in direction of rotation  
only - until brushes seat properly. In addition, stone  
slip ring with a fine stone. Brushes must be seated  
100%.  
1. Fully open the air bleeding valve by turning it  
counter clockwise, it is located on top of the fuel  
injection pump next to the oil filler. (see figure D.1)  
Arcing or excessive exciter brush wear indicates a  
possible misaligned shaft. Have an authorized Field  
Service Shop check and realign the shaft.  
Air Bleeding  
Valve  
CAUTION  
IDLER MAINTENANCE  
Before doing electrical work, disconnect the bat-  
tery.  
FIGURE D.1  
------------------------------------------------------------------------  
When installing a new battery or using a jumper bat-  
tery to start the engine, be sure the battery polarity is  
connected properly. The correct polarity is negative  
ground. Damage to the engine alternator and the  
Engine Control Unit can result from incorrect connec-  
tion.  
2. Turn the engine by pressing the start button until  
the engine runs smoothly (this should take approxi-  
mately 10 seconds).  
3. Fully close the air bleeding valve by turning it  
clockwise.  
Contact your Kubota Engine repair facility if problems  
persist.  
1. Proper operation of the idler requires good  
grounding of the Engine Control Unit, current  
sensing printed circuit board and battery.  
2. If desired, the welder can be used without automat-  
ic idling by setting the “Idler” switch to the “High”  
position.  
NAMEPLATES  
Whenever routine maintenance is performed on this  
machine - or at least yearly - inspect all nameplates  
and labels for legibility. Replace those which are no  
longer clear. Refer to the parts list for the replace-  
ment item number.

MAINTENANCE  
GFCI RECEPTACLE TESTING AND RESET-  
TING PROCEDURE  
The GFCI receptacle should be properly tested at  
least once every month or whenever it is tripped. To  
properly test and reset the GFCI receptacle:  
• If the receptacle has tripped, first carefully remove  
any load and check it for damage.  
• If the equipment has been shut down, it must be  
restarted.  
• The equipment needs to be operating at high idle  
speed and any necessary adjustments made on the  
control panel so that the equipment is providing at  
least 80 volts to the receptacle input terminals.  
• The circuit breaker for this receptacle must not be  
tripped. Reset if necessary.  
• Push the "Reset" button located on the GFCI recep-  
tacle. This will assure normal GFCI operation.  
• Plug a night-light (with an "ON/OFF" switch) or other  
product (such as a lamp) into the GFCI receptacle  
and turn the product "ON".  
• Push the "Test" button located on the GFCI recepta-  
cle. The night-light or other product should go  
"OFF".  
• Push the "Reset" button, again. The light or other  
product should go "ON" again.  
If the light or other product remains "ON" when the  
"Test" button is pushed, the GFCI is not working prop-  
erly or has been incorrectly installed (miswired). If  
your GFCI is not working properly, contact a qualified,  
certified electrician who can assess the situation,  
rewire the GFCI if necessary or replace the device.
