engIne SaFeTY  
„ neveR run engine without an air filter or with a dirty air  
filter.Severe engine damage may occur.Service air filter  
frequently to prevent engine malfunction.  
„ The engine fuel exhaust gases contain poisonous carbon  
monoxide. This gas is colorless and odorless, and can  
cause death if inhaled.  
„ neveR tamper with the factory settings  
of the engine or engine governor. Damage  
to the engine or equipment can result  
if operating in speed ranges above the  
maximum allowable.  
„ The engine of this equipment  
requires an adequate free  
flow of cooling air. neveR  
operate this equipment in  
any enclosed or narrow area  
where free flow of the air is  
restricted. If the air flow is  
restricted it will cause injury to people and property and  
serious damage to the equipment or engine.  
„ neveR tip the engine to extreme angles during lifting as  
it may cause oil to gravitate into the cylinder head, making  
the engine start difficult.  
„ 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 turbochargers, and reduce  
the operating performance.  
„ DO nOT place hands or fingers inside engine  
compartment when engine is running.  
„ neveR operate the engine with heat shields or  
guards removed.  
„ Keep fingers, hands hair and clothing away  
from all moving parts to prevent injury.  
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.  
„ DO nOT remove the radiator cap while the engine is hot.  
High pressure boiling water will gush out of the radiator  
and severely scald any persons in the general area of  
the generator.  
Wet stacking does not 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.  
„ DO nOT remove the coolant drain plug  
while the engine is hot. Hot coolant will  
gush out of the coolant tank and severely  
scald any persons in the general area of  
the generator.  
„ DO nOT remove the engine oil drain plug while the  
engine is hot. Hot oil will gush out of the oil tank and  
severely scald any persons in the general area of the  
„ State Health Safety Codes and Public Resources  
Codes specify that in certain locations, spark arresters  
must be used on internal combustion engines that use  
hydrocarbon fuels.A spark arrester is a device designed  
to prevent accidental discharge of sparks or flames  
from the engine exhaust. Spark arresters are qualified  
and rated by the United States Forest Service for this  
purpose. In order to comply with local laws regarding  
spark arresters, consult the engine distributor or the  
local Health and Safety Administrator.  
„ neveR touch the hot exhaust manifold,  
muffler or cylinder.Allow these parts to cool  
before servicing equipment.

FueL SaFeTY  
„ Check the tire air pressure on both towing vehicle and  
trailer. Trailer tires should be inflated to 50 psi cold.  
Also check the tire tread wear on both vehicles.  
„ DO nOT start the engine near spilled fuel or combustible  
fluids. Diesel fuel is extremely flammable and its vapors  
can cause an explosion if ignited.

„ Store fuel in appropriate containers, in well-ventilated  
areas and away from sparks and flames.  
„ The maximum speed for highway towing is55 mpHunless  
posted otherwise.Recommended off-road towing is not to  
exceed 15 mpH or less depending on type of terrain.  
„ neveR use fuel as a cleaning agent.  
„ DO nOT smoke around or near the  
equipment. Fire or explosion could result  
from fuel vapors or if fuel is spilled on a  
hot engine.  
„ Avoid sudden stops and starts.This can cause skidding,  
or jack-knifing. Smooth, gradual starts and stops will  
improve towing.  
„ Avoid sharp turns to prevent rolling.  
„ Trailer should be adjusted to a level position at all times  
when towing.  
„ Check with your local county or state safety  
towing regulations, in addition to meeting  
Department of Transportation (DOT)  
SafetyTowing Regulations, before towing  
your light tower.  
„ Raise and lock trailer wheel stand in up position when  
„ Place chock blocks underneath wheel to prevent rolling  
while parked.  
„ In order to reduce the possibility of an accident while  
transporting the light tower on public roads, aLWaYS  
make sure the trailer that supports the light tower and  
the towing vehicle are mechanically sound and in good  
operating condition.  
„ Place support blocks underneath the trailer’s bumper  
to prevent tipping while parked.  
„ Use the trailer’s swivel jack to adjust the trailer height to  
a level position while parked.  
„ aLWaYS shutdown engine before transporting.  
„ Make sure the hitch and coupling of the towing vehicle  
are rated equal to, or greater than the trailer “gross
