Safe Operation of High Pressure Hose
If the hose leaks, it may cause fire or faulty operation, resulting in serious injury or damage.
If the bolt loose is found, stop operations and screw up/down the bolts to the specified tightening
torque. If there is any damage to the hose, stop the operation immediately, and contact with the
excavator dealer of XUGONG.
If there are any of the following problems, replace the hose:
－
Damage or leakage of hydraulic pipe connection.
－
Cladding frayed or disconnected, or strengthening layer wire exposed.
－
Cladding expands in some places.
－
Movable parts distorted or crushed.
－
Impurities inside cladding.
Waste
To prevent pollution, particular attention should be paid to the treatment of waste:
Discharge the oil from the machine into the
container; do not discharge it directly to the ground,
or into the sewers, rivers, oceans or lakes.
When dealing with hazardous materials, such as
engine oil, fuel oil, cooling fluid, solvents, filter and
batteries, it is necessary to comply
with the laws and regulations.
Air Conditioner Maintenance
If the air conditioner refrigerant gets into the eyes, it may cause blindness; if the refrigerant comes into
contact with skin, it can cause frostbite.
Compressed Air
When cleaning with compressed air, the particles flying out may cause injury on person or damage on
machines.
When cleaning filter or radiator with compressed air, make sure to wear goggles, dust masks, gloves
and other protective equipment.
Periodic Replacement of Safety-critical Parts
For long-term safety of in operation of the machine, there is need for regular lubrication and
maintenance. To further enhance security, the safety-related parts such as hoses, seat belts should be
periodically replaced.
When exceeds the allotted time, the material of parts will naturally change. Reuse will cause
deterioration, wear and damage. Finally, these parts may break down and cause serious injury or
damage. When the operating, it is difficult to judge how long these parts can keep working according
to an external inspection or touch, so replace it regularly
If there are any defects in safety-critical parts, replace or repair it even it has not reached the allotted
time.
