PRECAUTIONS FOR MAINTENANCE
It is dangerous and may cause personal injury.
Always observe the following.
• Always use the tyres specified by Komatsu and maintain the specified inflation pressure.
• Before inflating tyres, always check the wheel rims and the tyre walls and tread for dents, cuts, broken
plies, or other defects.
• If the tyre pressure goes down abnormally or the rim parts do not fit the tyre, there is a problem with the tyre
or rim parts; contact the Komatsu distributor for repairs.
• Inflating tyres using a compressed air gun with pressure gauge.
• Make sure that there is nobody in the vicinity before start-
ing to inflate a tyre. To inflate the tyre, stand in front of the
tread side.
• Never exceed the inflation pressures specified for each
type of tyre. Always make sure that the pressure is identi-
cal for the right and left tyres.
• Do not adjust the tyre inflation pressure immediately after
travelling at high speed or carrying out operations under
heavy load.
• Never carry out welding or light a fire near the tyre.
HANDLE ACCUMULATOR AND GAS SPRING
This machine is equipped with an accumulator. Even after the engine stops, if the work equipment control lever
is operated after stop of the engine in the direction to lower the work equipment, the work equipment goes down
with its own weight.
After stopping the engine, set the lock lever to LOCK position.
The accumulator and gas spring are charged with high-pressure nitrogen gas. If the accumulator is handled
mistakenly, it may cause an explosion. It is dangerous and may cause serious personal injury or death. Always
observe the following.
• Do not disassemble.
• 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 the accumulator, or subject it to any im-
pact.
• When disposing of the accumulator, the gas must be re-
leased. Ask your Komatsu distributor to perform this work.

caused by flying dust or particles.
