SAFETY WORKING
A
Do not work on the machine while under the
influence of alcohol, medication, orothersubstances
or while fatigued.
A
Wear close fitting clothing and safety equipment
appropriate to the job.
A
Use tools appropriate to the work. Makeshift tools,
parts, and procedures are not recommended.
A
When servicing is performed together by two or
more persons, take care to perform all work safely.
A
Do not touch the rotating or hot parts while the
engine is running.
A
Never remove the radiator cap while the engine is
running, or immediately after stopping. Otherwise,
hot water will spout out from radiator. Only remove
radiator cap when cool enough to touch with bare
hands. Slowly loosen the cap to first stop to relieve
pressure before removing completely.
A
Escaping fluid (fuel or hydraulic oil) under pressure
can penetrate the skin causing serious injury.
Relieve pressure before disconnecting hydraulic or
fuel lines. Tighten all connections before applying
pressure.
A
Wear a suitable hearing protective device such as
earmuffs or earplugs to protect againstobjectionable
or uncomfortable loud noises.
AVOID FIRES
A
Fuel is extremely flammable and explosive under
certain conditions. Do not smoke or allow flames or
sparks in your working area.
A
To avoid sparks from an accidental short circuit,
always disconnect the battery negative cable first
and connect it last.
A
Battery gas can explode. Keep sparks and open
flame away from the top of battery, especially when
charging the battery.
A
Make sure that no fuel has been spilled on the

Sulfuric acid in battery electrolyte is poisonous. It is
strong enough to burn skin, clothing and cause
blindness if splashed into eyes. Keep electrolyte
away from eyes, hands and clothing. If you spill
electrolyte on yourself, flush with water, and get
medical attention immediately.
PREPARE FOR EMERGENCIES
