NOTE Gives helpful information.
BEFORE SERVICING AND REPAIRING
1. Read all safety instructions in this manual and be
aware of the safety decals on your machine itself.
2. Thoroughly clean your work area and the machine.
3. Make sure the machine is on firm and level ground
and that the parking brake is set.
4. Lower the implement to the ground.
5. Stop the engine and remove the key.
6. Disconnect the negative battery cable.
7. Place a “DO NOT OPERATE” tag in operator station.

SAFETY WORKING
1. Do not operate or service the machine while under
the influence of alcohol, medication, or other
substances.
2. Never wear loose fitting clothing and always use
safety equipment appropriate to the job.
3. Never use improvised tools, parts or procedures.
Use only recommended tools appropriate to the
work.
4. Be careful to perform all work safely when servic-
ing is done by two or more people.
5. Always support the machine by safety stands. Never
work under the machine that is supported solely
by a jack.
6. Do not touch any rotating or hot parts while the
engine is running.
7. Never remove the radiator cap while the engine is
running, or immediately after stopping. Only remove
radiator cap when it is cool enough to touch with
bare hands. Slowly loosen the cap to relieve pres-
sure before removing completely.
8. 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.
C34W003A
C34W004A
AVOID FIRES
1. Never smoke or allow flames or sparks in your work
area, as fuel is extremely flammable and explosive
under certain conditions.
2. Always disconnect the negative battery cable first
and reconnect it last to avoid sparks from an acci-
dental short circuit.
3. Battery gas will ignite. Keep sparks and open flame
away from the top of battery, especially while
charging.
4. Be careful not to spill fuel on the engine.

DISPOSE OF FLUIDS PROPERLY
Observe relevant environmental protection regulations
when disposing of oil, fuel, coolant, electrolyte and
other harmful waste. Never pour fluids into the ground,
down a drain, or into a stream, pond, or lake.
C34W008A
VENTILATE WORK AREA
Exhaust contains poisonous carbon monoxide, so you
should never run the engine in a closed area. If the
engine must be running while performing maintenance,
make sure the area is well ventilated.
PREVENT ACID BURNS
Sulfuric acid in battery electrolyte is poisonous. It is
strong enough to burn skin, clothing and cause blind-
ness 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.
