17. GUIDES TO MAINTENANCE 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. 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 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 you have only oil which is a different brand from the one that is used in the machine, do not add it but replace all the oil. PC450-ENG 3-4
