SAFETY WORKING

Do not work on the machine while under the

influence of alcohol, medication, orothersubstances

or while fatigued.

Wear close fitting clothing and safety equipment

appropriate to the job.

Use tools appropriate to the work. Makeshift tools,

parts, and procedures are not recommended.

When servicing is performed together by two or

more persons, take care to perform all work safely.

Do not touch the rotating or hot parts while the

engine is running.

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.

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.

Wear a suitable hearing protective device such as

earmuffs or earplugs to protect againstobjectionable

or uncomfortable loud noises.

AVOID FIRES

Fuel is extremely flammable and explosive under

certain conditions. Do not smoke or allow flames or

sparks in your working area.

To avoid sparks from an accidental short circuit,

always disconnect the battery negative cable first

and connect it last.

Battery gas can explode. Keep sparks and open

flame away from the top of battery, especially when

charging the battery.

Make sure that no fuel has been spilled on the

engine.

VENTILATE WORK AREA

If the engine mustbe running to do some work, make

sure the area iswell ventilated. Neverrun the engine

in a closed area. The exhaust gas contains

poisonous carbon monoxide.

DISPOSE OF FLUIDS PROPERLY

Do not pour fluids into the ground, down a drain, or

into a stream, pond, or lake. Observe relevant

environmental protection regulations when

disposing of oil, fuel, coolant, electrolyte and other

harmful waste.

PREVENT ACID BURNS

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

Keep a first aid kit and fire extinguisher handy at all

times.

Keep emergency numbers for doctors, ambulance
