PRECAUTIONS FOR MAINTENANCE
The accumulator is charged with high-pressure nitrogen gas, so mistaken operation may cause an explosion,
which will lead to serious injury or death. Always observe the following.
•
Do not disassemble it.
•
Do not bring it near flame or dispose of it in fire.
•
Do not make holes in it, weld it, nor use a cutting torch.
•
Do not hit or roll it, or subject it to any impact.
•
When disposing of the accumulator, the gas must be re-
leased. Ask your Komatsu distributor to perform this work.
PRECAUTIONS FOR COMPRESSED AIR
•
When performing cleaning with compressed air, there is a hazard of serious personal injury or death
caused by flying dust or particles.
•
When using compressed air to clean the filter element or radiator, wear protective eyeglasses, 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.
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,
batteries, and DEF.
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 the defined life parts
that have a particularly close relation to safety, such as hoses and the seat belt.
Replacement of the 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.
