Safety during maintenance
To avoid any accident:
– Be sure to remember the maintenance regulations before you start working.
– Keep your workplace clean and dry.
– Do not spray water or steam inside the cabin.
– Do not lubricate or maintain the machine while moving.
– Avoid body limbs contact, or clothes getting sucked in, rotating parts.
Before starting maintenance:
– Park the machine on flat ground.
– Lower the bucket to the ground.
– Run the engine for 5 minutes at low speed and empty load.
– Stop the engine, turn off electric power and remove the key from the switch
– Move the controls several times to release the residue pressure within the
hydraulic system.
– Hang up the warning plate "No Operation" on the operating joystick. Set the
safety lever to the "lock" position.
– Let the engine cool down.
NOTICE: If maintenance needs to be done while the engine is still running,
a qualified driver in the cab must be involved in the process.
– If the excavator must be lifted during maintenance, maintain the angle
between the boom and arm between 90°and 110°. Support any lifted
machine part firmly and do not work under the movable boom's vicinity.
– Check the parts at regular intervals and repair or replace them according to
the needs.
– Keep all the parts in good working state and install them correctly.
– Replace the worn or damaged parts in time, and remove any accumulated
grease, oil or scrap.
– Adopt non-flammable cleaning oil and do not use fuel, gasoline or other
highly flammable substances to clean the parts or surface.
If spilled on any machine parts, or surfaces, clean them instantly.
Disconnect the grounding cable (- pole) of the battery before regulating the
electric system or performing any welding on the machine.
Ensure adequate lighting at the workplace. If working below or inside the
machine, always use guarded work lights. Otherwise the bulb may ignite any
of the flammable liquids (fuel, engine oil, anti-freezing or washing fluid) it
contact or in case it breaks.
