SAFETY
PRECAUTION 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.
WASTE MATERIAL
To prevent pollution, pay careful attention to the method of disposing of waste materials.
Always put oil drained from your machine in containers. Never
drain oil directly onto the ground or dump into the sewage
system, rivers, the sea, or lakes.
Obey appropriate laws and regulations when disposing of
harmful objects such as oil, fuel, coolant, solvent, filters, and
batteries.
MAINTENANCE FOR AIR CONDITIONER
If air conditioner refrigerant gets into your eyes, it may cause blindness; if it touches your skin, it may cause frostbite.
Never touch refrigerant.
COMPRESSED AIR
When carrying out cleaning with compressed air, there is a hazard of serious injury caused by flying particles.
When using compressed air to clean elements or the radiator, always wear safety goggles, dust mask, gloves,
and other protective equipment.
PERIODIC REPLACEMENT OF SAFETY CRITICAL PARTS
To enable the machine to be used safely for long periods, be particularly careful to periodically replace the
seatbelt, hoses, and other parts which have a close relationship to safety.
See Replacing critical parts: PERIODIC REPLACEMENT OF SAFETY CRITICAL PARTS (PAGE 4-14)
The material of these components naturally changes over time, and repeated use causes deterioration, wear, and
fatigue. As a result, there is a hazard that these components may fail and cause serious injury or death. It is
difficult to judge the remaining life of these components from external inspection or the feeling when operating,
so always replace them at the specified interval.
Replace or repair safety-critical parts if any defect is found, even when they have not reached the time specified
interval.
