24.6 EVERY 500 HOURS SERVICE

Maintenance for every 100 and 250 hours should be carried out at the
same time.
24.6.1 REPLACE FUEL FILTER CARTRIDGES
• Engine is at high temperature immediately after the machine
has been operated. Wait for engine to cool down before re-
placing the filter.
• Do not bring fire or sparks near the fuel.
• When cranking the engine, confirm the safety around the en-
gine, as the engine may start.
Prepare a filter wrench and a container to catch the fuel.
1. Set the container to catch the fuel under the filter cartridges.
2. Using a filter wrench, turn primary fuel filter cartridge
counterclockwise to remove it. Repeat for secondary fuel filter car-
tridge .
3. Clean the filter holder, fill new filter cartridges with clean fuel, coat
the packing surface with engine oil, then install them to the filter
holder.
4. When installing, tighten until the packing surface contacts the seal
surface of the filter holder, then tighten it up 1/2 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.
5. After replacing the fuel filter cartridges, bleed the air.
Bleed the air according to the following procedures.
