INTRODUCTION

Avoid a battery explosion

• The gas released by the batteries can be flammable

and may explode.

• Keep sparks, matches and flames away from the bat-

teries.

• Never short-circuit the battery terminals to check their

charge. Use a voltmeter.

• Do not charge a frozen battery, as it may explode.

• Warm the battery to

16.0 °C

(

60.8 °F

) before you charge

the battery.

• Battery electrolyte is poisonous.

• If the battery explodes, the electrolyte can reach the

eyes with consequent risk of blindness.

• Be sure to wear eye protection.

SP0052

Avoid burns

• After machine operation, the engine coolant is hot and

under pressure.

• The engine, radiator, and cooling system lines contain

hot water and steam.

• Skin contact with hot water or steam can cause severe

burns.

• Avoid possible burns that may be caused by hot water

or steam under pressure.

• Do not remove the radiator cap until the engine is cool.

• After the engine has cooled, turn the cap slowly to allow

all the pressure to be released. We advise you to wear
safety goggles and gloves to perform this operation.

• After the pressure is released, remove the cap com-

pletely.

• The hydraulic fluid reservoir is under pressure.

• Be sure to release all pressure before removing the cap.

• Engine oil, reducer oil and hydraulic fluid also become

hot during operation.

• Like the engine, the pressure lines and lubrication sys-

tem components are also heated during machine oper-
ation.

SP0049

• In case of maintenance in any of these components,

wait until the system completely cools.

• Wait until all the fluids and components cool before

starting any maintenance work.
