Fire, explosion and poisoning prevention
⚫
Avoid contact with wires when the excavator is
transported, walked, or excavated, otherwise it will cause
serious casualties.
⚫
Excavator electrical appliances and wiring should be
checked frequently. If they are found to be damaged, or
aging, they must be replaced in time to prevent a short
circuit of electrical wiring and causing fire.
⚫
Keep the wire connectors clean and securely fixed.
Check whether the wires are loose or damaged every
day, tighten loose joints or wire clamps, and repair the
damaged wires.
⚫
Do not place flammable and explosive materials inside
the excavator to prevent fires.
⚫
When refueling, the engine must be stopped. Refueling
at a place far away from the fire and does not leave the
machine.
⚫
When refueling, do not allow the fuel to spill onto
overheated surfaces or parts of the electrical system.
⚫
After refueling, wipe off the spilled fuel or engine oil, and tighten the fuel and engine oil tank caps.
⚫
Remove the leaves, wood chips, paper chips, and other flammable materials accumulated or stuck to the
engine, exhaust pipe, muffler, and engine compartment in time.
⚫
Do not place oil-soaked rags in the machine to avoid spontaneous fire and burning.
⚫
The user should configure a fire extinguisher in the machine and put it in a place where it is easily accessible.
⚫
When welding the machine, it is strictly forbidden to do without isolating the hydraulic oil pipeline and the fuel
pipeline.
⚫
To prevent fires caused by hydraulic pipelines: check whether the clamps, guards, and cushions of all hoses
and pipes are firmly fixed in place. If it is loose, it will vibrate and rub against other parts during operation,
causing hose damage, high pressure oil spraying, and fire hazards or serious injuries.
⚫
Keep the battery away from fire and avoid high temperature, otherwise, it will cause an explosion.
⚫
For excavators with a sealed cab, check the tightness of the intermediate partition to prevent engine exhaust
gas from entering the cab and causing driver poisoning.
⚫
It is strictly forbidden to work in poorly ventilated areas to prevent the driver from suffocating.
⚫
In the event of a fire, do not use water to extinguish the fire. Use a powder fire extinguisher or sand to
extinguish the fire. You can also use a cover or tarp to extinguish the fire.
