SAFETY
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.
PRECAUTIONS FOR DISPOSING OF WASTE MATERIALS
To prevent pollution, pay full attention to the way to dispose of waste materials.
• Always drain the oil from your machine in containers. Nev-
er drain the oil and coolant directly onto the ground or
dump into the sewage system, rivers, seas, or lakes.
• Obey appropriate laws and regulations when disposing of
harmful objects such as oil, fuel, coolant, solvent, filters,
and batteries.
Avoid exposure to burning rubber or plastics which produce a toxic gas that is harmful to people.
• When disposing of parts made of rubber or plastics (hoses, cables, and harnesses), always comply with the
local regulations for disposing industrial waste products.
METHOD FOR 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 DEFINED LIFE PARTS
• For using the machine safely for a long period, always perform periodic replacement of defined life parts
that have a particularly close relation to safety, such as hoses and the seat belt.
Replacement of defined life parts: See "PERIODIC REPLACEMENT OF DEFINED LIFE PARTS (7-2)"
• 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 defined life parts if any defect is found, even when they have not reached the specified
replacement time.
