SAFETY
PRECAUTIONS FOR MAINTENANCE
HANDLING ACCUMULATOR AND GAS SPRING
This machine is equipped with an accumulator. Even after the engine has been stopped, it is possible to operate
the work equipment control lever in the LOWER direction for a short time to allow the work equipment to go down
under its own weight.
After stopping the engine, set the work equipment lock lever to the LOCK position and turn the parking brake switch
ON.
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 precautions.
Do not disassemble the accumulator.
Do not bring it near 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.
Please contact your Komatsu distributor to have this work
performed.
PRECAUTIONS WITH COMPRESSED AIR
When carrying out cleaning with compressed air, there is a hazard of serious personal injury caused by flying dust
or particles.
When using compressed air to clean the filter element or radiator, wear safety glasses, 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.
METHOD OF 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.
