MAINTENANCE 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. The warning tag is supplied together with the tools. Obey precautions: During machine 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 the 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. Never weld any pipe or tube containing fuel or oil. Fire prevention: Use nonflammable cleaner or light oil for cleaning parts. Keep flame or lighted cigarette away from light oil. Clamp faces: When O-rings or gaskets are removed, clean the clamp faces and replace the O-rings and gaskets with new ones. Be sure to carefully install 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 underneath machine:
When working in rocky areas, check for damage underneath the machine and for damaged bolts and nuts. Precautions when washing machine: Never spray steam or water directly at the radiator. Do not allow water to get on any electrical component 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 working 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. On job sites were heavy-duty operations are common, reduce the maintenance intervals and grease the machine more frequently.
Dusty work sites: When working at dusty work sites, do as follows: Inspect the air cleaner clogging pilot lamp to see whether the air cleaner is plugged up. Clean the air cleaner at shorter intervals than specified. Clean the radiator core 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 oils: Never mix oils of different brands. If the only oil you have is a different brand from the one that is used in the machine, do not add it in but replace all the oil. WA450-3MC 3-3
