SAFETY
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 electrocution. Never touch
the inside of the controller or the engine injector portion.
If it is necessary to touch the inside of the controller or the engine
injector portion, please contact your Komatsu distributor.
NOISE
When carrying out 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 from the machine is too loud, it may cause temporary or permanent hearing problems.
PRECAUTIONS WITH HIGH-PRESSURE GREASE WHEN ADJUSTING TRACK TENSION
Grease is pumped into the track tension adjustment system
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 property damage.
When loosening grease drain plug (1) to loosen the track
tension, never loosen it more than one 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).
DO NOT DISASSEMBLE RECOIL SPRING
Never disassemble the recoil spring assembly. The recoil spring assembly has a powerful spring that acts to reduce
the impact on the idler. If it is disassembled by mistake, the spring may shoot out and cause serious personal injury
or death.
It is necessary to disassemble the recoil spring assembly, always ask your Komatsu distributor to carry out the
operation.
