Compressed Air; Periodic Replacement Of Safety Critical Parts - Komatsu PC78US-6 Operation & Maintenance Manual

SAFETY

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

For using the machine safely for an extended period of time, replace safety-critical parts like hoses and seat belts
periodically.
Replacement of safety-critical parts: See "SAFETY CRITICAL PARTS (PAGE 4-13)".
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.
