DO NOT DISASSEMBLE RECOIL SPRING
Never disassemble the recoil spring assembly.
The recoil spring assembly has a powerful spring that acts to
reduce the impact on the idler. If it is disassembled by mistake,
the spring may shoot out and cause serious personal injury or
death. If it is necessary to disassemble it, ask your Komatsu
distributor to perform the work.
HANDLE ACCUMULATOR
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 parking brake lever and work equipment lock lever to LOCK positions.
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.
