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.
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.
Batteries
Before starting work on the engine, disconnect batteries
to prevent inadvertent starting
of
the engine.
DO NOT SMOKE while servicing batteries. Lead acid
batteries 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.
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 lines 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.
Exhaust System
Exhaust products
of
any internal combustion engine are
toxic and can cause injury,
or
death if inhaled.
All
engine
applications, especially those within
a
confined area,
should be equipped with an exhaust system to discharge
gases to the outside atmosphere.
Do
not use exhaust gases to heat a compartment
Make sure that
your
exhaust system
is
free
of
leaks.
Ensure 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
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 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
immediately and have it inspected and repaired at once by a
competent mechanic.
Cooling System
Coolants under pressure have a higher boiling Point than
water.
DO
NOT open a radiator pressure cap when
coolant temperature is above
212°F
(l00°C)
or while
engine
is
running.
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.
