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.

DCA-10SPX4 — 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.
