inside of the machine.
During maintenance, do not carry any unnecessary tools and spare parts in the pockets.
1.8.13 PRECAUTIONS IN THE USE OF HAMMER
When using a hammer, be sure to wear safety glasses, safety helmets and other
protective clothing, and place a brass rod between the hammer and area being
hammered.
When hammering hard parts, such as a pin or a bearing, there will be the injury risk of debris flying into the eye.
1.8.14 WELDING REPAIR
Welding operation shall be performed by qualified welders, and conduct in place fitted with
appropriate equipment. Welding will produce gas, so there is hazard of causing fire and
electric shock when doing welding. Therefore welding must comply with the following
notes:
Shut down the battery terminals to prevent battery explosions.
Clear the paint of welding parts to prevent harmful gases.
Welding in the hydraulic device or pipe or near them will produce combustible vapors
and sparks that have risk of ignition; therefore, it is necessary to avoid such welding.
If the welding sparks fly directly onto rubber hoses, wires or pipes with pressure, these
tubes may suddenly rupture or wire insulation layer may be damaged, so it is
necessary to cover these things with fire damper.
Wear protective clothing during welding operation.
Keep the welding work site well ventilated.
Clean all flammable materials before welding, and equip with fire extinguishers on the
working site.
1.8.15 PRECAUTIONS OF BATTERY DURING MAINTENANCE
During the repair of electrical systems or welding operation on the machine, it is
necessary to shut down battery negative (-) pole, in order to shut down the circuit to
ensure safety.
1.8.16 TREATMENT OF ABNORMAL STATUS
If any abnormal status is found during overhaul, repair it. Especially that when the
machine is in operation, there is any irregularity in braking system, steering system or
working device system, which can lead to serious accidents.
