SAFETY INFORMATION  
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.  
ENGINE SAFETY  
WARNING  
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  
generator.  
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.  
CAUTION  
NEVER touch the hot exhaust manifold,  
muffler or cylinder.Allow these parts to cool  
before servicing equipment.  
NOTICE  
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.  
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.

SAFETY INFORMATION  
ALWAYS inspect the hitch and coupling for wear. NEVER  
tow a trailer with defective hitches, couplings, chains, etc.  
FUEL SAFETY  
DANGER  
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.  
ALWAYS make sure the trailer is equipped with a safety  
chain.  
ALWAYS refuel in a well-ventilated area, away from  
sparks and open flames.  
ALWAYS properly attach trailer’s safety chains to towing  
vehicle.  
ALWAYS use extreme caution when working with  
flammable liquids.  
ALWAYS make sure the vehicle and trailer directional,  
backup, brake and trailer lights are connected and  
working properly.  
DO NOT fill the fuel tank while the engine is running  
or hot.  
DO NOT overfill tank, since spilled fuel could ignite if it  
comes into contact with hot engine parts or sparks from  
the ignition system.  
DOT Requirements include the following:  
• Connect and test electric brake operation.  
• Secure portable power cables in cable tray with tie  
wraps.  
Store fuel in appropriate containers, in well-ventilated  
areas and away from sparks and flames.  
The maximum speed for highway towing is 55 MPH unless  
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.  
TOWING SAFETY  
CAUTION  
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  
towing.  
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  
vehicle weight rating.”

FUELTANK  
The LT12 Light Tower is powered by a diesel engine that  
is equipped with automatic shutdowns for low oil pressure,  
high coolant temperature, and alternator charge failure.  
The 30-gallon fuel tank provides up to 64 hours of run time  
while running at 3/4 load.  
STABILITY  
TRAILER DESIGN  
The light tower can be raised vertically in excess of 31.5  
feet (9.6 meters) by means of a manual winch. The tower  
tensioning system is designed to provide the necessary  
tension to safely control the pivot of the tower. The light  
tower has a wind stability of up to 65 mph with outriggers  
and jackstands fully deployed.  
The trailer design of the LT12 light tower withstands the  
rigors of the jobsite in addition to providing smooth highway  
towing.
