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

fumes and gases. When welding, keep  
your head out of the fume. Use enough  
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 within applicable OSHA PEL and  
ACGIH TLV limits using local exhaust or mechanical  
ventilation. In confined spaces or in some circum-  
stances, 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.  
3.f. Maintain the electrode holder, work clamp, welding cable and  
welding machine in good, safe operating condition. Replace  
damaged insulation.  
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.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.  
3.j. Also see Items 6.c. and 8.  
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.  
5.e. Read and understand the manufacturer’s instructions for this  
equipment and the consumables to be used, including the  
material safety data sheet (MSDS) and follow your  
employer’s 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 manufacturer’s  
recommendations.  
8.c. Ground the equipment in accordance with the U.S. National  
Electrical Code and the manufacturer’s recommendations.  
6.h. Also see item 1.c.  
6.I. Read and follow NFPA 51B “ Standard for Fire Prevention  
During Welding, Cutting and Other Hot Work”, available  
from NFPA, 1 Batterymarch Park, PO box 9101, Quincy, Ma  
022690-9101.  
6.j. Do not use a welding power source for pipe thawing.

SAFETY  
PRÉCAUTIONS DE SÛRETÉ  
6. Eloigner les matériaux inflammables ou les recouvrir afin de  
prévenir tout risque d’incendie dû aux étincelles.  
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:  
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 d’incendie.  
Sûreté Pour Soudage A L’Arc  
8. S’assurer que la masse est connectée le plus prés possible  
de la zone de travail qu’il est pratique de le faire. Si on place  
la masse sur la charpente de la construction ou d’autres  
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 d’incendie ou d’echauffement des chaines et des  
câbles jusqu’à ce qu’ils se rompent.  
1. Protegez-vous contre la secousse électrique:  
a. Les circuits à l’électrode 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 s’isoler 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.  
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  
d’opérations de dégraissage, nettoyage ou pistolage. La  
chaleur ou les rayons de l’arc peuvent réagir avec les vapeurs  
du solvant pour produire du phosgéne (gas fortement toxique)  
ou autres produits irritants.  
d.Ne jamais plonger le porte-électrode dans l’eau 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.  
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.  
f. Si on utilise la machine à souder comme une source de  
courant pour soudage semi-automatique, ces precautions  
pour le porte-électrode s’applicuent aussi au pistolet de  
soudage.  
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 n’importe quelle partie  
du corps.  
PRÉCAUTIONS DE SÛRETÉ POUR  
LES MAChINES À SOUDER À  
TRANSFORMATEUR ET À  
REDRESSEUR  
3. Un coup d’arc peut être plus sévère qu’un coup de soliel,  
donc:  
a. Utiliser un bon masque avec un verre filtrant approprié  
ainsi qu’un verre blanc afin de se protéger les yeux du ray-  
onnement de l’arc et des projections quand on soude ou  
quand on regarde l’arc.  
1. Relier à la terre le chassis du poste conformement au code de  
l’électricité et aux recommendations du fabricant. Le dispositif  
de montage ou la piece à souder doit être branché à une  
bonne mise à la terre.  
b. Porter des vêtements convenables afin de protéger la  
peau de soudeur et des aides contre le rayonnement de  
l‘arc.  
2. Autant que possible, I’installation et l’entretien du poste seront  
effectués par un électricien qualifié.  
c. Protéger l’autre personnel travaillant à proximité au  
soudage à l’aide d’écrans appropriés et non-inflammables.  
3. Avant de faires des travaux à l’interieur de poste, la debranch-  
er à l’interrupteur à la boite de fusibles.  
4. Des gouttes de laitier en fusion sont émises de l’arc de  
soudage. Se protéger avec des vêtements de protection libres  
de l’huile, tels que les gants en cuir, chemise épaisse, pan-  
talons sans revers, et chaussures montantes.  
4. Garder tous les couvercles et dispositifs de sûreté à leur  
place.  
5. Toujours porter des lunettes de sécurité dans la zone de  
soudage. Utiliser des lunettes avec écrans lateraux dans les  
zones où l’on pique le laitier.

INSTALLATION  
When this welder is mounted on a truck or trailer, it’s  
frame must be electrically bonded to the metal frame  
of the vehicle. Use a #8 or larger copper wire connect-  
ed between the machine grounding stud and the  
frame of the vehicle.  
SAFETY PRECAUTIONS  
WARNING  
Do not attempt to use this equipment until you  
have thoroughly read the engine manufacturer’s  
manual supplied with your welder. It includes  
important safety precautions, detailed engine  
starting, operating and maintenance instructions,  
and parts lists.  
Where this engine driven welder is connected to  
premises wiring such as that in your home or shop, it’s  
frame must be connected to the system earth ground.  
See further connection instructions in the section enti-  
tled “Standby Power Connections”, as well as the arti-  
cle on grounding in the latest National Electrical Code  
and the local code.  
------------------------------------------------------------------------  
ELECTRIC ShOCK can kill.  
• Do not touch electrically live parts or  
electrode with skin or wet clothing.  
• Insulate yourself from work and  
ground.  
In general, if the machine is to be grounded, it should  
be connected 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 insulat-  
ed joints, or to the metal framework of a building  
which has been effectively grounded. The National  
Electrical Code lists a number of alternate means of  
grounding electrical equipment. A machine grounding  
• Always wear dry insulating gloves.

• Do not operate with doors open or  
guards off.  
• Stop engine before servicing.  
• Keep away from moving parts.  
------------------------------------------------------------------------  
SPARK ARRESTER  
Some federal, state, or local laws may require that  
gasoline 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, the K1898-1 spark arrester must be  
installed and properly maintained.  
See additional warning information at  
front of this operator’s manual.  
------------------------------------------------------------------------  
MAChINE GROUNDING  
Because this portable engine driven welder or genera-  
tor creates it’s own power, it is not necessary to con-  
nect it’s frame to an earth ground, unless the machine  
is connected to premises wiring (your home, shop,  
etc.).  
CAUTION  
An incorrect arrester may lead to damage to the  
engine or adversely affect performance.  
------------------------------------------------------------------------  
TOWING  
The recommended trailer for use with this equipment  
(1)  
for road, in-plant and yard towing by a vehicle is  
Lincoln’s K2635-1. If the user adapts a non-Lincoln  
trailer, he must assume responsibility that the method  
of attachment and usage does not result in a safety  
hazard nor damage the welding equipment. Some of  
the factors to be considered are as follows:  
WARNING  
To prevent dangerous electric shock, other equip-  
ment to which this engine driven welder supplies  
power must:  
be grounded to the frame of the welder using a  
grounded type plug, or be double insulated.  
1. Design capacity of trailer vs. weight of Lincoln  
equipment and likely additional attachments.  
Do not ground the machine to a pipe that carries  
explosive or combustible material.  
------------------------------------------------------------------------

At higher altitudes, Welder output de-rating may be  
necessary. For maximum rating, de-rate the welder  
output 3.5% for every 1000 ft. (305m) above 3000 ft.  
(914m). If operation will consistently be at altitudes  
above 5,000 ft. (1525m), a carburetor jet designed for  
high altitudes should be installed. This will result in  
better fuel economy, cleaner exhaust and longer  
spark plug life. It will not give increased power.  
Contact your local authorized engine service shop for  
high altitude jet kits that are available from the engine  
manufacturer.

ANGLE OF OPERATION  
Internal combustion engines are designed to run in a  
level condition which is where the optimum perfor-  
mance is achieved. The maximum angle of operation  
for the engine is 15 degrees from horizontal in any  
direction. If the engine is to be operated at an angle,  
provisions must be made for checking and maintain-  
ing the oil at the normal (FULL) oil capacity in the  
crankcase in a level condition.  
CAUTION  
Do not operate with a high altitude jet installed at  
altitudes below 5000 ft. (1525m). This will result in  
the engine running too lean and result in higher  
engine operating temperatures which can shorten  
engine life.

CAUTION  
A GFCI (Ground Fault Circuit Interrupter) electrical  
receptacle is a device to protect against electric shock  
should a piece of defective equipment connected to it  
develop a ground fault. If this situation should occur,  
the GFCI will trip, removing voltage from the output of  
the receptacle. If a GFCI receptacle is tripped see the  
MAINTENANCE section for detailed information on  
testing and resetting it. A GFCI receptacle should be  
properly tested at least once every month.  
Do not connect any plugs that connect to the  
power receptacles in parallel.  
------------------------------------------------------------------------  
Start the engine and set the “IDLER” control switch  
to the “High Idle” mode. Set the “CONTROL” to 10.  
Voltage is now correct at the receptacles for auxiliary  
power. This must be done before a tripped GFCI  
receptacle can be reset properly. See the MAINTE-  
NANCE section for more detailed information on  
testing and resetting the GFCI receptacle.  
The 120V auxiliary power receptacles should only be  
used with three wire grounded type plugs or approved  
double insulated tools with two wire plugs.  
The RANGER 3 PHASE can provide both three phase  
and single phase power, up to 11,500 watts of 480  
volts AC, three phase 60Hz power for peak use, and  
up to 10,500 watts of 480 volts AC, three phase 60Hz  
power for continuous use, up to 10,500 watts of  
120/240 volts AC, single phase 60Hz power for peak  
use, and up to 9,500 watts of 120/240 volt AC, single  
phase 60Hz power for continuous use. The front of  
the machine includes four receptacles for connecting  
the AC power plugs; one 20 amp 480 volt 3 phase

14-50R receptacle and two 20 amp 120 volt NEMA 5-  
20R receptacles. Output voltage is within +/-10% at all  
loads up to rated capacity. Do not use 3 phase  
power and single phase power simultaneously. All  
auxiliary power is protected by cuircuit breakers.  
The current rating of any plug used with the system  
must be at least equal to the current load through the  
associated receptacle.  
480 Volt 3 Phase Receptacle with Ground  
The 480 volt receptacle can supply 12.6 amps of 3  
phase power, or up to 15 amps of single phase  
power. A NEMA plug L16-20P is required to use this  
receptacle. The ground (GND) connection is connect-  
ed to the machine frame, it is NOT the neutral of the

INSTALLATION  
MOTOR STARTING  
If 480 volt single phase load is to be run, the X lead must be  
one of the leads in the circuit in order for the automatic idle to  
function. Using a NEMA plug L16-20P, connect either X and Y  
or X and Z to the receptacle, as well as the machine ground.  
Most 1.5 hp AC single phase motors can be started if there is  
no load on the motor or other load connected to the machine,  
since the full load current rating of a 1.5 hp motor is approxi-  
mately 20 amperes (10 amperes for 240 volt motors). The  
motor may be run at full load when plugged into only one side of  
the duplex receptacle. Larger motors through 2 hp can be run  
provided the receptacle rating as previously stated is not  
exceeded. This may necessitate 240V operation only.  
All auxiliary power is protected by circuit breakers with the fol-  
lowing values:

The 480 volt 3 phase output of the RANGER 3 PHASE is capa-  
ble of running most 480VAC 3 phase motors up to 10HP. A  
10HP motor must be started with no load on the motor and no  
other load connected to the machine, since the full load current  
of a 10HP 480VAC 3 phase motor is approximately 12.5 amps.  
Refer to the reconnect phase output to any load, the ground at  
the 3 phase receptacle is NOT the neutral of 3 phase connec-  
tion, and should under no circumstance be connected to the  
neutral of any 3 phase load.  
GND

GENERALꢀDESCRIPTION  
The RANGER® 3 PHASE is a twin-cylinder, gasoline  
driven, multiprocess arc welder and AC power gener-  
ator. It is built in a heavy gauge steel case for durabili-  
ty on the job site.  
After welding ceases (and no auxiliary power is  
being drawn), the engine will return to low idle  
after approximately 10 to 14 seconds.  
Auxiliary Power  
With the engine running at low idle and auxiliary  
power for lights or tools is drawn (approximately  
00-150 watts or greater) from the receptacles, the  
engine will accelerate to high speed. If no power  
is being drawn from the receptacles (and not  
welding) for 10-14 seconds, the idler reduces the  
engine speed to low idle.

OPERATION  
STOPPING ThE ENGINE  
STARTING/ShUTDOWN INSTRUCTIONS  
STARTING ThE ENGINE  
Remove all welding and auxiliary power loads and  
allow engine to run at low idle speed for a few minutes  
to cool the engine.  
WARNING  
• Do not touch electrically live parts  
of electrode with skin or wet  
clothing.  
Stop the engine by placing the Engine switch in the  
“OFF”  
position.  
A fuel shut off valve is not required on the RANGER®  
3 PHASE because the fuel tank is mounted below the  
engine.  
• Keep flammable material away.  
bREAK-IN PERIOD  
• Insulate yourself from work and  
ground. Wear eye, ear, and body  
protection.  
It is normal for any engine to use a greater amount of  
oil until the break-in is accomplished. Check the oil  
level twice a day during the break-in period (approxi-  
mately 50 running hours).  
• Keep your head out of the fumes.  
• Use ventilation or exhaust to  
remove fumes from breathing zone.  
IMPORTANT: IN ORDER TO ACCOMPLISh ThIS  
bREAK-IN, ThE UNIT ShOULD bE  
SUbJECTED TO MODERATE  
LOADS, WIThIN ThE RATING OF  
ThE MAChINE. AVOID LONG IDLE

Be sure all Pre-Operation Maintenance has been per-  
formed. Also, read the Engine Owner’s Manual before  
starting for the first time.  
LOADS AND ALLOW ENGINE TO  
COOL bEFORE ShUTDOWN.  
Remove all loads connected to the AC power recepta-  
cles. Use the choke control as follows:  
The engine manufacturer’s recommendation for the  
running time until the first oil change is as follows:  
KOhLER ENGINE - Always pull the choke control out  
when starting the engine; cold, warm or hot.  
KOHLER  
CH23S  
Turn the engine switch to the “start”  
position and  
crank the engine until it starts. Release the switch as  
soon as the engine starts, slowly return the choke  
control to the full “in” position (choke open),  
5 HRS  
and turn the switch to the Auto Idle(  
/
)
position. Do not turn the switch to the “start” position  
while the engine is running because this will cause  
damage to the ring gear and/or starter motor  
The oil filter is to be changed at the second oil  
change. Refer to the Engine Owner’s Manual for more  
information.  
After running at high engine speed for 10-14 seconds,  
the engine will go to low idle.  
Allow the engine to warm up by letting it run at low idle  
for a few minutes.

OPERATION  
WELDING PROCESS  
The RANGER® 3 PHASE can be used with a broad  
range of DC stick electrodes. See “Welding Tips 1”  
included with the RANGER® 3 PHASE for electrodes  
within the rating of this unit and recommended weld-  
ing currents of each.  
For any electrodes the procedures should be kept  
within the rating of the machine. For electrode infor-  
mation see the appropriate Lincoln publication.  
STICK (CONSTANT CURRENT) WELDING  
SCRATCh START TIG (CONSTANT CURRENT)  
WELDING  
Connect welding cables to the "TOꢀWORK” and  
"ELECTRODE” studs. Start the engine. Set the  
"Polarity” switch to the desired polarity. The “RANGE”  
switch markings indicate the maximum current for that  
range as well as the typical electrode size for that  
range. The “OUTPUT” Control provides fine adjust-  
ment of the welding current within the select range.  
For maximum output within a selected range set the  
“OUTPUT” Control at 10. For minimum output within a  
selected range set the “OUTPUT” Control at 5. (“OUT-  
PUT” Control settings below 5 may reduce arc stabili-  
ty) For best overall welding performance set the  
“RANGE” Switch to the lowest setting and the OUT-  
PUT” Control near the maximum to achieve the  
desired welding current.  
The RANGER® 3 PHASE can be used for Scratch-Start of DC  
TIG welding applications. To initiate a weld, the course and fine  
output control knobs must be set for the desired current. The  
tungsten electrode is then scratch on the work which establish-  
es the arc.  
To stop the arc, simply lift the TIG torch away from the work  
piece. The tungsten may then be scratched on the work piece  
to restrike the arc.  
If a high frequency start is desired, the K930-2 TIG Module can  
be used with the RANGER® 3 PHASE. The settings are refer-  
enced.  
The RANGER® 3 PHASE and any high frequency generating  
equipment must be properly grounded. See the K930-2 TIG  
Module operating manuals for complete instructions on installa-  
tion, operation and maintenance.

NOTE: Engine life will be reduced if the oil and oil  
filter are not changed according to the manufacturer’s  
recommendation.  
• Use in open, well ventilated areas or  
vent exhaust outside.  
ENGINE OIL ChANGE  
Drain the oil while the engine is warm to assure rapid  
and complete draining.  
------------------------------------------------------------------------  
MOVING PARTSꢀcan injure.  
• Do not operate with doors open or  
guards off.  
• Stop engine before servicing.  
• Remove the oil filler cap and dipstick. Remove the  
yellow cap from the oil drain valve and attach the  
flexible drain tube supplied with the machine. Push  
in and twist the drain valve counterclockwise. Pull  
the valve out and drain the oil into a suitable contain-  
er.  
• Keep away from moving parts.  
------------------------------------------------------------------------  
See additional warning information  
throughout this operator’s manual and  
the Engine manual as well.  
------------------------------------------------------------------------  
• Close the drain valve by pushing in and twisting  
clockwise. Replace the yellow cap.  
• Refill to the upper limit mark on the dipstick with the  
recommended oil. Tighten the oil filler cap securely.  
Read the Safety Precautions in the front of this manual  
and the engine instruction manual before working on  
this machine.  
ENGINE OIL REFILL CAPACITIES  
Without oil filter replacement:  
• 1.7qt. (1.6 liter)-Kohler  
Keep all equipment safety guards, covers, and devices  
in position and in good repair. Keep hands, hair, cloth-  
ing, and tools away from gears, fans, and all other  
moving parts when starting, operating, or repairing the  
equipment.  
With oil filter replacement:  
• 2.0qt. (1.9 liter)-Kohler  
Routine Maintenance  
At the end of each day’s use, refill the fuel tank to  
minimize moisture condensation in the tank.  
Running out of fuel tends to draw dirt into the fuel  
system. Also, check the crankcase oil level and  
add oil if indicated.

MAINTENANCE  
Use 4-stroke motor oil that meets or exceeds the  
requirements for API service classification SG or SH.  
Always check the API SERVICE label on the oil con-  
tainer to be sure it includes the letters SG or SH.  
AIR CLEANER AND OThER MAINTENANCE  
Air Cleaner - With normal operating conditions, the  
maintenance schedule for cleaning and re-oiling  
the foam pre-filter is every 25 hours and replace-  
ment of the air cleaner filter every 100 hours.  
More frequent servicing is required with dusty  
operating conditions. Refer to the maintenance  
section of the Engine Owner’s Manual for more  
information.  
SAE 10W-30 is recommended for general, all-tempera-  
ture use, -5 F to 104 F (-20 C to 40 C).  
See Engine Owner’s Manual for more specific informa-  
tion on oil viscosity recommendations.  
Wash your hands with soap and water after handling  
used oil.  
Refer to the maintenance section of the Engine  
Owner’s Manual for the maintenance schedule,  
spark plug servicing, cooling system servicing, and  
fuel filter replacement.  
Please dispose of used motor oil in a manner that is  
compatible with the environment. We suggest you take  
it in a sealed container to your local service station or  
recycling center for reclamation.  
Blow out the machine with low pressure air period-  
ically. In particularly dirty locations, this may be  
required once a week.  
Do not throw it in the trash, pour it on the ground or  
down a drain.  
• Output Ranger Selector and Polarity Switches:  
Switch contacts should not be greased. To keep  
contacts clean, rotate the switch through its entire  
range frequently. Good practice is to turn the han-  
dle from maximum to minimum setting twice each  
morning before starting to weld.  
OIL FILTER ChANGE  
1. Drain the engine oil.  
2. Remove the oil filter, and drain the oil into a suitable  
container. Discard the used oil filter.  
3. Clean the filter mounting base, and coat the gasket  
of the new oil filter with clean engine oil.  
4. Screw on the new oil filter by hand, until the gasket  
contacts the filter mounting base, then use an oil fil-  
ter socket tool to tighten the filter an additional 1/2 to  
7/8 turn.  
5. Refill the crankcase with the specified amount of the  
recommended oil. Reinstall the oil filler cap.  
6. Start the engine and check for oil filter leaks.  
7. Stop the engine, and check the oil level. If neces-  
sary, add oil to the upper limit mark on the dipstick.

SLIP RINGS  
1. When replacing, jumping, or otherwise connecting  
the battery to the battery cables, the proper polarity  
must be observed. Failure to observe the proper  
polarity could result in damage to the charging cir-  
cuit. The positive (+) battery cable has a red termi-  
nal cover.  
A slight amount of darkening and wear of the slip rings  
and brushes is normal. Brushes should be inspected  
when a general overhaul is necessary. If brushes are  
to be replaced, clean slip rings with a fine emery  
paper.  
2. If the battery requires charging from an external  
charger, disconnect the negative battery cable first  
and then the positive battery cable before attaching  
the charger leads. Failure to do so can result in
