MAINTENANCE 24.7 EVERY 500 HOURS SERVICE Maintenance for every 50, 100 and 250 hours service should be carried out at the same time. 24.7.1 REPLACE FUEL FILTER CARTRIDGE WARNING Engine temperature remains high immediately after the machine has been operated. Wait for engine to cool down before replacing the filter. Keep fire and/or sparks away from the fuel. The fuel filters are spin-on type, which cannot be cleaned and should not be disturbed until they are replaced. For average conditions, use the interval listed in the Scheduled Maintenance Guide (sooner if power loss is evident; more often for unusually contaminated fuel). Prepare a filter wrench and a container to catch the fuel.

Clean the area around the fuel filters. 2. Using a filter wrench, remove filter cartridges. 3. Clean the filter holder. 4. Fill a new filter cartridge with clean fuel, coat the packing surface with engine oil, then install it to the filter holder. 5. When installing, tighten until the packing surface contacts the seal surface of the filter holder, then tighten it Ѕ to ѕ of a turn. If the filter cartridge is tightened too far, the packing will be damaged and this will lead to leakage of fuel.
If the filter cartridge is too loose, fuel will also leak from the packing, so always tighten to the correct amount. 3-54 WA320-3MC
