PRECAUTIONS FOR MAINTENANCE
PRECAUTIONS FOR HIGH VOLTAGE
When the engine is running and immediately after it is stopped,
high voltage is generated inside the engine controller and the
engine injector, and there is danger of electric shock. Never
touch the inside of the engine controller or the injector part of
the engine. If it is necessary to touch the inside of the engine
controller or the injector part of the engine, consult your Komat-
su distributor.
PRECAUTIONS FOR NOISE
When performing maintenance of the engine and you are exposed to noise for long periods of time, wear ear
covers or ear plugs while working.
If the noise is too loud, it may cause temporary or permanent hearing problems.
PRECAUTIONS FOR HIGH-PRESSURE GREASE WHEN ADJUSTING TRACK
TENSION
• Grease is pumped into the track tension adjustment sys-
tem under high pressure. If the specified procedure for
maintenance is not followed when making adjustment,
grease drain plug (1) may fly out and cause serious injury
or death or property damage.
• When loosening grease drain plug (1) to loosen the track
tension, never loosen it more than 1 turn. Loosen the
grease drain plug slowly.
• Never put your face, hands, feet, or any other part of your
body close to grease drain plug (1).
