Service Manual

Safety Precautions
Before operating the engine, read the Operator's Manual and
become familiar with it and the equipment.
Safe and efficient
operatlon can be achieved only
If the equipment Is
properly operated and maintained.
The following symbols, found throughout this manual, alert you
to potentially dangerous conditions to the operator, service per-
sonnel, or
the equipment.
Thls symbol warns of immediate hazards
whlch will result in severe personal Injury or death.
WARNING This symbol refers to a hazard or unsafe
practice whlch can result in severe personal Injury or
death.
CAUTION) This symbol refers to a hazard or unsafe
practlce whlch can result In personal Injury or product or
property damage.
Fuels, electrical equipment, batteries, exhaust gases and
moving parts present potential hazards that can result in severe
personal injury. Take care in following these recommended
procedures.
All local, state and federal codes should be
consulted and complied with.
WARNING Thls engine is not designed or Intended for
use In any type of aircraft. Use of this engine In aircraft can
result In engine failure and cause severe personal injury or
death.
GENERAL
Provide appropriate fire extinguishers and install them in
convenient locations. Use an extinguisher rated ABC by
NFPA.
Make sure that all fasteners on the engine are secure and
accurately torqued. Keep guards in position over fans,
driving belts, etc.
If it is necessary to make adjustments while the engine is
running, use extreme caution when close to hot exhausts,
moving parts, etc.
Used engine oils have been identified by some state and
federal agencies as causing cancer or reproductive
toxicity. When checking or changing engine oil, take care
not
to ingest, breathe the fumes, or contact used oil.
Do not work on this equipment when mentally or
physically fatigued, or after consuming any alcohol or
drug that makes the operation of equipment unsafe.
BATTERIES
Before starting work on the engine, disconnect batteries
to prevent inadvertent starting of the engine. Disconnect
negative cable first.
DO NOT SMOKE while servicing batteries. Lead acid bat-
teries give
off a highly explosive hydrogen gas which can
be ignited by flame, electrical arcing or by smoking.
Verify battery polarity before connecting battery cables.
Connect negative cable last.
PROTECT AGAINST MOVING PARTS
Do not wear loose clothing in the vicinity of moving parts,
such as PTO shafts, flywheels, blowers, couplings, fans,
belts, etc.
Keep your hands away from moving parts.
FUEL SYSTEM
DO NOT fill fuel tanks while engine is running.
DO NOT smoke or use an open flame in the vicinity of the
engine or
fuel tank. Internal combustion engine fuels are
highly flammable.
Fuel line must be of steel piping, adequately secured, and
free from leaks. Piping at the engine should be approved
flexible line. Do not use copper piping for flexible lines
as
copper will work harden and become brittle enough to
break.
Be sure all fuel supplies have a positive shutoff valve.
Benzene and lead, found in some gasoline, have been
identified by some state and federal agencies as causing
cancer or reproductive toxicity. When checking, draining
or adding gasoline, take care not to ingest, breathe the
fumes, or contact gasoline.
EXHAUST SYSTEM
Exhaust products of any internal combustion engine are
toxic and can cause injury, or death
if inhaled. When
operating the engine in a confined area, make sure the
ventilation system is operating properly.
DO NOT use exhaust gases to heat a compartment.
Make sure that your exhaust system is free of leaks. Make
sure that exhaust manifolds are secure and are not
warped by bolts unevenly torqued.
EXHAUST GAS IS DEADLY!
Exhaust gases contain carbon monoxide, a poisonous gas that
can cause unconsciousness and death. It is an odorless and
colorless gas formed during combustion of hydrocarbon
fuels.
Symptoms of carbon monoxide poisoning are:
Dizziness
Vomiting
Headache
0 Muscular Twitching
Weakness and Sleepiness
Throbbing in Temples
If you experience any of these symptoms, get out into fresh air
immediately, shut down the unit and do not
use it until it has
been inspected.
The best protection against carbon monoxide inhalation is
proper installation and regular, frequent inspections of the
complete exhaust system. If you notice a change
in the sound
or appearance of exhaust system, shut the unit down immedi-
ately and have it inspected and repaired at once by a competent
mechanic.
KEEP THE UNIT AND SURROUNDING AREA CLEAN
Make sure that oily rags are not left on or near the engine.
Remove all unnecessary grease and
oil from the unit.
Accumulated grease and oil can cause overheating and
subsequent engine damage and present a potential fire
hazard.
