the storage location of fire extinguisher and be familiar with the use method.
1.5.4
Entry intocab
1.5.4.1 Before entering the cab, remove the sludge and fine sands on the shoes which will
accumulate on the supporting points of throttle pedal and brake pedal and impede the pedal reset and
may speed up the wear of pushing lever. The accumulated sediments on these places shall be
cleaned immediately.
1.5.5
Pressure stranded in the system
1.5.5.1 The pressure may be trapped in the hydraulic system. When releasing the pressure trapped
in the system, the machine or optional components may suddenly move. Carefully remove the
hydraulic pipes or fittings. The released high-pressure fluids may swing the pipe and may eject out.
The fluids penetrated into the body may cause serious personnel injury and even death. The pressure
relief of working hydraulic pipes can be realized by laying the bucket flat on the ground and moving the
boom and bucket control lever back and forth 5 to 6 times at lowering, lifting, tilting forward and tilting
backward positions.
1.5.6
Penetration injury fromfluids
1.5.6.1 Even if the engine has been shut down for a long time, the pressure may still exist in the
hydraulic circuit. If the pressure is not properly released, it will lead to high-speed ejection of the
hydraulic oil or pipe plug, etc.
1.5.6.2 Prior to the release of pressure, it is prohibited to remove any hydraulic part, otherwise
personnel injury may be caused
1.5.6.3 When checking the leakage, be sure to use the wooden board or cardboard as a baffle.
Ejected fluids under pressure may penetrate the human tissue. The fluids penetrated into the body
may cause serious personnel injury or even death. Even a pinhole leakage may also lead to serious
personnel injury. If the fluids are sprayed onto your skin, you shall be treated immediately by the doctor
familiar with this type of personnel injury.
1.5.7
Compressed air and high-pressure fluid
1.5.7.1 Compressed air or pressure water will make the debris or hot water splash, possibly causing
personnel injury.
1.5.7.2 When conducting the cleaning operation with the compressed air or pressure water, wear the
protective clothes, protective shoes, and goggles or face shield.
1.5.7.3 The maximum pressure of the air for cleaning shall be lower than 0.2MPa.
1.5.7.4 The maximum pressure of the water for cleaning shall be lower than0.25MPa.
1.5.8
Prevention of crush and laceration
1.5.8.1 Support the equipment properly before conducting any operation or maintenance under the
machine. Do not support the equipment with hydraulic cylinder, for the device may fall if the control
handle is moved or hydraulic pipe is cracked,
1.5.8.2 Support the cab properly before conducting any operation under it.
