Warning tag:
Attach the warning tag to the starting switch or other appropriate control lever to avoid someone who is not aware
of the circumstances from starting the engine.
Obey precautions
During the operation, always obey the precautions on the safety label attached to the machine.
Welding instructions
•
Turn off the engine starting switch
•
Do not apply more than 200 V continuously
•
Connect grounding cable within 1 m from the area to be welded.
•
Avoid seals or bearings from being between the area to be welded and the position of grounding point.
•
Do not use the area around the work equipment pins or the hydraulic cylinders as the grounding point.
Fire prevention:
Use non-flammable cleaner or light oil for cleaning parts. Keep flame or cigarette light away from light oil
Clamp face:
When O-rings or gaskets are removed, clean the clamp faces and replace the O-rings and gaskets with new ones.
Be sure to fit O-rings and gaskets when assembling.
Objects in your pockets:
Keep your pockets free of loose objects which can fall out and drop into the machinery; especially when you work
on the machinery while bending over it.
Checking undercarriage:
When working in rocky areas, check for damage to the undercarriage and for looseness, flaws, wear and damage
in bolts and nuts. Loosen the track tension a little when working in such areas.
Precautions when washing the machine:
•
Never spray steam or water directly on the connectors and mechatronics parts.
•
Do not allow water to get on the monitors and controllers inside the operator's cab.
•
Never spray steam or water directly at the radiator or oil cooler portions.
Pre- and post-work checks:
Before starting work in mud, rain, snow or at seashore, check plugs and valves for tightness.
Wash the machine immediately after the work to protect components from rusting.
Lubricate components more frequently than usual. Be sure to lubricate work equipment pins daily if they are
submerged in water.
Dusty worksite:
When working at dusty worksites, do as follows:
•
Inspect the air cleaner clogging monitor to see whether the air cleaner is blocked up. Clean the air cleaner at
shorter intervals than specified.
•
Clean the radiator more frequently to avoid clogging.
•
Clean and replace the fuel filter frequently.
•
Clean electrical components, especially the starting motor and alternator, to avoid accumulation of dust.
Avoid mixing oil:
Never mix oils of different brands. If you have only oil which is a different brand from the one that is used in the
machine, do not add it but replce all the oil.
