SAFETY
PRECAUTIONS FOR MAINTENANCE
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 glasses, dust mask, gloves,
and other protective equipment.
PERIODIC REPLACEMENT OF SAFETY-CRITICAL PARTS
In order for the machine to be operated safely for a long time, it is necessary to add oil and to carry out service
and maintenance at periodic intervals. In order to further increase safety, components with a strong relationship
to safety, such as hoses and seat belts, must be replaced at periodic intervals.
Replacement of safety-critical parts: See "PERIODIC REPLACEMENT OF 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.
