Safety Messages and Operating Instructions could result in  
injury to yourself and others.  
This Owner's Manual has been  
developed to provide complete  
instructions for the safe and  
efficient operation of the  
MQ Power Generator.  
WARNING - LETHAL EXHAUST GASES  
NOTE  
Gasoline engine exhaust gases contain  
poisonous carbon monoxide. This gas is  
colorless and odorless, and can cause  
Before using this generator,  
ensure that the operating individual has read and  
understands all instructions in this manual.  
DEATH if inhaled. NEVER operate this  
equipment in a confined area or enclosed structure that  
does not provide ample free flow air.  
WARNING - EXPLOSIVE FUEL  
SAFETY MESSAGE ALERT SYMBOLS  
Diesel fuel is extremely flammable, and  
its vapors can cause an explosion if  
ignited. DO NOT start the engine near  
spilled fuel or combustible fluids.  
DO NOT fill the fuel tank while the engine  
is running or hot.  
The three (3) Safety Messages shown below will inform you  
about potential hazards that could injure you or others.The  
Safety Messages specifically address the level of exposure  
to the operator, and are preceded by one of three words:  
DANGER, WARNING, or CAUTION.  
DO NOT overfill tank, since spilled fuel could ignite if it  
comes into contact with hot engine parts or sparks from  
the ignition system. Store fuel in approved containers, in  
well-ventilated areas and away from sparks and flames.  
NEVER use fuel as a cleaning agent.  
DANGER  
You WILL be KILLED or SERIOUSLY injured if you  
do not follow directions.  
WARNING  
WARNING - BURN HAZARDS  
Engine components can generate extreme  
heat.To prevent burns, DO NOT touch these  
areas while the engine is running or  
immediately after operations. NEVER  
operate the engine with heat shields or heat  
guards removed.

TLG-12SPX4 — SAFETY MESSAGE ALERT SYMBOLS  
WARNING - ROTATING PARTS  
CAUTION - RESPIRATORY HAZARDS  
NEVER operate equipment with covers,  
or guards removed. Keep fingers, hands,  
hair and clothing away from all moving  
parts to prevent injury.  
ALWAYS wear approved respiratory  
protection.  
CAUTION - ACCIDENTAL STARTING  
CAUTION - SIGHT AND HEARING HAZARDS  
ALWAYS place the engine ON/OFF  
switch (MPEC) in the OFF/RESET  
position when the generator is not in use.  
ALWAYS wear approved eye and  
hearing protection.  
CAUTION - OVER-SPEED CONDITIONS  
CAUTION - EQUIPMENT DAMAGE MESSAGES  
NEVER tamper with the factory settings  
of the engine governor or settings.  
Personal injury and damage to the engine  
or equipment can result if operating in  
speed ranges above maximum allowable.  
Other important messages are provided throughout this  
manual to help prevent damage to your generator, other  
property, or the surrounding environment.  
CAUTION - ENGINE LOAD (WET-STACKING)  
Wet-Stacking is a common problem with diesel engines  
which are operated for extended periods with light or no  
load applied. When a diesel engine operates without  
sufficient load (less than 40% of the rated output) it will  
not operate at its optimum temperature. This will allow  
unburned fuel to accumulate in the exhaust system, which  
can foul the fuel injectors, engine valves and exhaust  
system, including turbocharges, and reduce the operating  
performance.  
This generator, other property, or  
the surrounding environment  
could be damaged if you do not  
follow instructions.  
In order for a diesel engine to operate at peak efficiency it  
must be able to provide fuel and air in the proper ratio and  
at a high enough engine temperature for the engine to  
completely burn all of the fuel.  
Wet stacking does usually cause any permanent damage  
and can be alleviated if additional load is applied to relieve  
the condition. It can reduce the system performance and  
increase maintenance. Applying an increasing load over a  
period of time until the excess fuel is burned off and the  
system capacity is reached usually can repair the condition.  
This can take several hours to burn off the accumulated  
unburned fuel.

Indoor Installation  
Exhaust gases from diesel engines are extremely poisonous.  
Whenever an engine is installed indoors the exhaust fumes  
must be vented to the outside.The engine should be installed  
at least two feet from any outside wall. Using an exhaust  
pipe which is too long or too small can cause excessive  
back pressure which will cause the engine to heat excessively  
and possibly burn the valves.  
When connecting the generator  
to any buildings electrical  
system ALWAYS consult with  
a licensed electrician.  
NOTE  
Mounting  
The generator must be mounted on a solid foundation (such  
as concrete) and set firmly on the foundation to isolate  
vibration of the generator when it is running. The generator  
must set at least 6 inches above the floor or grade level (in  
accordance to NFPA 110, Chapter 5-4.1). DO NOT remove  
the metal skids on the bottom of the generator. They are to  
resist damage to the bottom of the generator and to maintain  
alignment.

TLG-12SPX4 — GENERAL INFORMATION  
Open Delta Excitation System  
TLG-12SPX4Whisperwatt™ Series Familiarization  
Generator  
The generator is equipped with the state of the art "Open-  
Delta" excitation system. The open delta system consist of  
The MQ Power Model TLG-12SPX4 is a 13 kW generator  
(Figure 3) that is designed as a high quality portable (requires  
a trailer for transport) power source for telecom sites, lighting  
facilities, power tools, submersible pumps and other industrial  
and construction machinery.  
an electrically independent winding wound among stationary  
windings of the AC output section.  
There are four connections of the open delta A, B, C and D.  
During steady state loads, the power from the voltage regulator  
is supplied from the parallel connections of A to B, A to D,  
and C to D. These three phases of the voltage input to the  
voltage regulator are then rectified and are the excitation  
current for the exciter section.

Warning Lamp Unit  
When a heavy load, such as a motor starting or a short  
circuit occurs, the automatic voltage regulator (AVR)  
switches the configuration of the open delta to the series  
connection of B to C.This has the effect of adding the voltages  
of each phase to provide higher excitation to the exciter  
section and thus better voltage response during the  
application of heavy loads.

Extension Cables  
When electric power is to be provided to various tools or  
loads at some distance from the generator, extension cords  
are normally used. Cables should be sized to allow for  
distance in length and amperage so that the voltage drop  
between the generator and point of use (load) is held to a  
minimum. Use the cable selection chart (Table 6) as a guide  
for selecting proper extension cable size.

TLG-12SPX4 — LOAD APPLICATION/MAXIMUM AMPERAGE  
Single Phase Load  
Motors and motor-driven  
equipment draw much greater  
current for starting than during  
operation.  
Always be sure to check the nameplate on the generator  
NOTE  
and equipment to insure the wattage, amperage, frequency  
,
and voltage requirements are satisfactorily supplied by the  
generator for operating the equipment.  
Generally, the wattage listed on the nameplate of the  
equipment is its rated output. Equipment may require 130—  
150% more wattage than the rating on the nameplate, as  
the wattage is influenced by the efficiency, power factor and  
starting system of the equipment.  
An inadequate size connecting cable which cannot carry the  
required load can cause a voltage drop which can burn out  
the appliance or tool and overheat the cable. See Table 6.  
■
■
■
When connecting a resistance load such as an  
incandescent lamp or electric heater, a capacity of up to  
the generating set’s rated output (kW) can be used.  
If wattage is not given on the  
equipment's  
name  
plate,  
approximate wattage may be  
determined by multiplying  
nameplate voltage by the  
nameplate amperage.  
When connecting a fluorescent or mercury lamp, a  
capacity of up to the generating set’s rated output (kW)  
multiplied by 0.6 can be used.  
When connecting an electric drill or other power tools,  
pay close attention to the required starting current  
capacity.  
WATTS = VOLTAGE x AMPERAGE  
The power factor of this generator is 0.8. See Table 5 below  
when connecting loads.  
When connecting ordinary power tools, a capacity of up to  
the generating set’s rated output (kW) multiplied by 0.8 can  
be used.

Service Daily  
General Inspection  
If the engine is operating in very dusty or dry grass  
conditions, a clogged air cleaner will result.This can lead to  
a loss of power, excessive carbon buildup in the combustion  
chamber and high fuel consumption. Change air cleaner  
more frequently if these conditions exists.  
Prior to each use, the generator should be cleaned and  
inspected for deficiencies. Check for loose, missing or  
damaged nuts, bolts or other fasteners. Also check for fuel,  
oil, and coolant leaks. Use Table 11 as a general engine  
maintenance guideline (Refer to the Engine Instruction  
Manual).  
Fuel Addition  
Air Cleaner  
Add diesel fuel (the grade may vary according to season  
and locations).  
Every 250 hours: Remove air cleaner element and clean the  
heavy duty paper element with light spray of compressed  
air. Replace the air cleaner as needed.  
RemovingWater from the FuelTank  
After prolonged use, water and other impurities accumulate  
in the bottom of the tank. Occasionally inspect the fuel  
tank for water contamination and drain the contents if  
required.  
Air Cleaner with Dust Indicator (If Equipped)  
This indicator is attached to the air cleaner. When the air  
cleaner element is clogged, air intake restriction becomes  
greater and the dust indicator signal shows RED meaning  
the element needs changing or service. After changing the  
air element, press the dust indicator button to reset the  
indicator.  
During cold weather, the more empty volume inside the  
tank, the easier it is for water to condense. This can be  
reduced by keeping the tank full with diesel fuel.

TLG-12SPX4 — MAINTENANCE  
Air Removal  
Flushing Out Radiator and Replacing Coolant  
If air enters the fuel injection system of a diesel engine,  
starting becomes impossible. After running out of fuel, or  
after disassembling the fuel system, bleed the system  
according to the following procedure. See the KUBOTA  
Engine Manual for details.  
Open both cocks located at the crankcase side and at  
the lower part of the radiator and drain coolant.Open the  
radiator cap while draining. Remove the overflow tank  
and drain.  
Check hoses for softening and kinks. Check clamps for  
signs of leakage.  
To restart after running out of fuel, turn the switch to the  
“ON” position for 15-30 seconds. Try again, if needed. This  
unit is equipped with an automatic air bleeding system.  
Flush the radiator by running clean tap water through  
radiator until signs of rust and dirt are removed.DO NOT  
clean radiator core with any objects, such as a  
screwdriver.  
Check Oil Level  
Check the crankcase oil level prior to each use, or when the  
fuel tank is filled. Insufficient oil may cause severe damage  
to the engine. Make sure the generator is level.The oil level  
must be between the two notches on the dipstick as shown  
in Figure 12.  
Tighten both cocks and replace the overflow tank.  
Replace with coolant as recommended by the engine  
manufaturer.  
Close radiator cap tightly.  
Replacing Oil Filter  
WARNING - BURN HAZARDS  
Remove the old oil filter.  
Apply a film of oil to the gasket on the new oil filter.  
Install the new oil filter.  
Allow engine to cool when flushing out  
radiator. Flushing the radiator while hot  
could cause serious burns from water or  
steam.  
After the oil cartridge has been replaced, the engine oil  
will drop slightly. Run the engine for a while and check  
for leaks before adding more oil if needed. Clean  
excessive oil from engine.  
Generator Storage  
Cleaning the Fuel Strainer  
For longe term storage of the generator the following is  
recommended:  
Clean the fuel strainer if it contains dust or water. Remove  
dust or water in the strainer cap and wash it in gasoline.  
Securely fasten the fuel strainer cap so that fuel will not  
leak. Check the fuel strainer every 200 hours of operation or  
once a month.  
Fill the fuel tank completely. Treat with a fuel stabilizer  
if necessary.  
Completely drain the oil from the crankcase and refill if  
necessary with fresh oil.  
Replacing Fuel Filter  
Clean the entire generator, internal and external.  
Cover the generating set and store in a clean, dry place.  
Disconnect the battery.  
Replace the fuel filter cartridge with new one every 500  
hours or so.  
Loosen the drain plug at the lower top of the fuel filter.  
Drain the fuel in the fuel body together with the mixed  
water. DO NOT spill the fuel during disassembly.  
Make sure engine coolant is at proper level.  
If generator is mounted on a trailer, jack trailer up and  
place on blocks so tires do not touch the ground or block  
and completely remove the tires.  
Vent any air.

TLG-12SPX4 —TRAILER MAINTENANCE  
Brakes  
Hydraulic Surge Brakes  
Trailer brakes should be inspected the first 200 miles of Hydraulic surge brakes (Figure 32) should not require any  
operation. This will allow the brake shoes and drums to seat special attention with the exception of routine maintenance  
properly. After the first 200 mile interval, inspect the brakes such as shoe and lining replacement. Brake lines should be  
every 3,000 miles. If driving over rough terrain, inspect the periodically checked for cracks, kinks, or blockage.  
brakes more frequently.  
Figure 32 displays the major hydraulic surge brake  
components that will require inspection and maintenance.  
Please inspect these components as required using steps 1  
through 8 and Table 12 as listed below:  
Brake Adjustment  
1. Place the trailer on jack stands. Make sure the jack  
stands are placed on secure level ground.  
2. Check the wheel and drum for free rotation.  
3. Remove the adjusting hole cover from the adjusting slot  
at the bottom brake backing plate.  
4. With a screwdriver or standard adjusting tool, rotate the

star wheel of the adjuster assembly to expand the brake  
shoes.  
Actuator  
5. Adjust the brake shoes outward until the pressure of the  
lining against the wheel drum makes the wheel difficult  
to turn.  
Hydraulic surge braking requires the installation of an actuator  
at the tongue of the trailer. Remember the surge or push of  
the trailer toward the tow vehicle automatically synchronizes  
the trailer brakes with the tow vehicle brakes. As the trailer  
pushes against the tow vehicle the actuator telescopes  
together and applies force to the master cylinder, supplying  
hydraulic pressure to the trailer brakes.  
6. Adjust, rotate the star wheel in the opposite direction  
until the wheel rotates freely with slight lining drag.  
7. Replace the adjusting hole cover and lower the trailer to  
the ground.  
Periodically check and test the surge “actuator” to make  
sure that it is functioning correctly. Never use an undersize  
actuator.  
8. Repeat steps 1 through 7 on the remaining brakes.
