PRECAUTIONS FOR MAINTENANCE
HANDLING ACCUMULATOR AND GAS SPRING
This machine is equipped with an accumulator. Even after the engine stops, if the work equipment control lever is
operated soon after stop of the engine in the direction to lower the work equipment, the work equipment goes down
under its own weight.
After stopping the engine, set the parking brake lever and the work equipment 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 that could lead to serious personal injury or death. For this reason, always
observe the following.
Do not disassemble the accumulator.
Do not bring it near open flame or dispose of it in fire.
Do not make holes in it, weld it, or use a cutting torch.
Do not hit or roll the accumulator, or subject it to any impact.
When disposing of the accumulator, the gas must be released.
Ask your Komatsu distributor to have this work performed.
PRECAUTIONS WITH 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.
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.
