SAFETY

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.
It is necessary to disassemble the recoil spring assembly, always
ask your Komatsu distributor to carry out the operation.

HANDLING ACCUMULATOR AND GAS SPRING

This machine is equipped with an accumulator. Even after the engine stops, the work equipment control levers can
be operated for a short time in the LOWER direction to allow the work equipment to go down under its own weight.
After stopping the engine, set the lock lever to the 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 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.

Please contact your Komatsu distributor to have this work
performed.
