SAFETY

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. 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 hose, deformed mouthpiece, damaged O-ring
Frayed or cut covering or exposed reinforcement wire layer
Covering swollen in places
Twisted or crushed movable portion of hose
Foreign material stuck to 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.

COMPRESSED AIR

When carrying out cleaning with compressed air, there is a hazard of serious injury caused by flying particles.
When using compressed air to clean elements or the radiator, always wear safety glasses, dust mask, gloves,
and other protective equipment.

PERIODIC REPLACEMENT OF SAFETY CRITICAL PARTS

For using the machine safely for an extended period of time, replace safety-critical parts like hoses and seat belts
periodically.
Replacement of safety-critical parts: See "SAFETY CRITICAL PARTS (PAGE 4-13)".
The material of these components naturally changes over time, and repeated use causes deterioration, wear, and
fatigue. As a result, there is a hazard that these components may fail and cause serious injury or death. It is
difficult to judge the remaining life of these components from external inspection or the feeling when operating,
so always replace them at the specified interval.
Replace or repair safety-critical parts if any defect is found, even when they have not reached the specified
replacement time.
