WASTE MATERIALS
To prevent pollution, pay careful attention to the method of disposing of waste materials.
q
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.
q
Obey appropriate laws and regulations when disposing of
harmful objects such as oil, fuel, coolant, solvent, filters, and
batteries.
AIR CONDITIONER MAINTENANCE
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
q
When carrying out cleaning with compressed air, there is a hazard of serious injury caused by flying particles.
q
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
q
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 (4-16)“.
q
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 operat-
ing, so always replace them at the specified interval.
q
Replace or repair safety-critical parts if any defect is found, even when they have not reached the time specified
interval.
