a)
Use the safety goggles or safety glasses to avoid the injuries of splashed metal pieces or fragments.
b)
In case of hitting the object, prevent others from entering into the working place.
During the maintenance of machine, warn the others that any unexpected
machine movement will cause the severe injuries, and hang up the nameplate
“No Operation” on the control lever before maintaining the machine.
Correct supporting of machine
Don’t maintain and repair the machine before supporting the machine.
a)
Fall the front-end working device always to the ground before maintaining and repairing the machine.
b)
If the machine or front-end working device must be lifted for maintenance and repair, support the
machine or front-end working device. Don’t use the slag bricks, cord tires or racks to support the
machine, because they may be fallen-in under the continuous load. Don’t work under the machine
supported with single jack.
Far from the rotating parts
a)
The entrapment of rotating part may cause the severe injuries.
b)
In case of working beside the rotating part, don’t make the hand, foot, clothes,
jewellery or hair entrapped by the rotating part.
Avoiding the fly out of part
a)
The grease in track-tension device is under a high pressure. In case of not obeying the following
matters, severe injury, blindness or death may be caused:
1)
Don’t remove the grease coupler or valve body.
2)
The body and face must be far away from valve body because it may fly out.
b)
The traction reducer has a certain pressure:
1)
Due to the possible flyout of part, the body and face must be away from the air
bleed bolt to avoid any injury.
2)
The gear oil is hot, which may lead to scald injury. After cooling the gear oil,
loosen the air bleed plug gradually to release the pressure.
Safety storage of fittings
The stored fittings such as bucket, hydraulic hammer and grafter may fall, resulting in severe injuries.
Store the fittings and apparatus safety to avoid falling, so the children and other personnel should be
far away from the storage area.
Pay attention to high-temperature fluid.
a)
Avoid the heat injury caused by the sprayed high-temperature fluid. After the operation, the cooling
water of engine is hot and has a certain pressure; there is hot water or steam in engine or radiator.
If the skin contacts the spilled hot water or steam, the severe skin burns will be caused.
1)
Avoid the burning of hot water that may be sprayed out. Don’t open the cover of
radiator before cooling the engine. In case of opening the cover, turn the cover to bottom
slowly, and remove the cover after releasing the pressure fully.
