SAFETY

MAINTENANCE FOR AIR CONDITIONER

If air conditioner refrigerant gets into your eyes, it may cause blindness; if it touches your skin, it may cause frost-
bite. Never touch refrigerant.

COMPRESSED AIR

When carrying out cleaning with compressed air, there is a hazard of serious injury or property damage
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

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 relation-
ship to safety, such as hoses and seat belts, must be replaced at periodic intervals.
Replacement of safety critical parts:
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 property
damage. 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 speci-
fied interval.
See "PERIODIC REPLACEMENT OF SAFETY CRITICAL PARTS
(PAGE 4-15)".
