SAFETY HANDLING HIGH-PRESSURE HOSES

If oil or fuel leaks from high-pressure hoses, it may cause fire or defective operation, which may lead to serious
injury or property damage. If any loose bolts are found, stop work and tighten to the specified torque. If any
damaged hoses are found, stop operations immediately and contact your Komatsu distributor.
Replace the hose if any of the following problems are found.
Damaged or leaking hydraulic fitting.
Frayed or cut covering or exposed reinforcement layer of wire.
Covering swollen in places.
Twisted or crushed movable portion.
Foreign material embedded in covering.

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.

AIR CONDITIONER MAINTENANCE

bite.
Never touch refrigerant.

COMPRESSED AIR

caused by flying particles.
