SAFETY INFORMATION
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.

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.

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.
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.

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.
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 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.

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.

SAFETY INFORMATION
FUEL SAFETY
DANGER

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 refuel in a well-ventilated area, away from
sparks and open flames.

ALWAYS use extreme caution when working with
flammable liquids.

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.

Store fuel in appropriate containers, in well-ventilated
areas and away from sparks and flames.

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.
TOWING SAFETY
CAUTION

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.

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.

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.”
ALWAYS inspect the hitch and coupling for wear. NEVER
tow a trailer with defective hitches, couplings, chains, etc.

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.
ALWAYS
make sure the trailer is equipped with
appropriate safety chains.
ALWAYS properly
attach trailer’s safety chains to towing
vehicle.
ALWAYS
make sure the vehicle and trailer directional,
backup, brake and trailer lights are connected and

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.

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.

Raise and lock trailer wheel stand in up position when
towing.
Place chock blocks underneath wheel to prevent
rolling
while parked.
Place support blocks
underneath the trailer’s bumper
to prevent tipping while parked.

