SAFETY

PRECAUTIONS WITH COMPRESSED AIR

When carrying out cleaning with compressed air, there is a hazard of serious personal injury caused by flying dust
or particles.
When using compressed air to clean the filter element or radiator, wear safety glasses, anti-dust mask, gloves,
and other protective equipment.

MAINTENANCE OF AIR CONDITIONER

If air conditioner refrigerant gets into your eyes, it may cause loss of sight; if it contacts your skin, it may cause
frostbite. Never loosen any parts of the cooling circuit.

DISPOSING OF WASTE MATERIALS

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.

METHOD OF SELECTING WINDOW WASHER FLUID

Use an ethyl alcohol base washer liquid.
Methyl alcohol base washer liquid may irritate your eyes, so do not use it.

PERIODIC REPLACEMENT OF SAFETY CRITICAL PARTS

To enable this machine to be used safely for a long period, always carry out periodic replacement of safety critical
parts that have a particularly close relation to safety, such as hoses and the seatbelt.
For details of the replacement of safety critical parts, see "PERIODIC REPLACEMENT OF SAFETY CRITICAL
PARTS (PAGE 4-16)".
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 personal 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 specified
replacement time.
