10.7 MAINTENANCE EVERY 500 HOURS
Perform this maintenance in tandem with maintenance every 50, 100 and 250 hours.
[1] REPLACEMENT OF ENGINE OIL AND ENGINE OIL FILTER
As parts and oil are hot immediately after the engine is stopped, there is a risk of burns. Begin
work after the temperature has dropped.
• Volume of replaced oil in the oil pan: 6.2 litres
• Have a filter wrench available.
Even the operation time is less than 500 hours after 6 months of operation, replace the oil and filter
cartridge in 6 months.
Also, replace it when the operation time becomes 500 hours with less than 6 months of operation.
1. Place a drain pan directly underneath the drain plug (P)
to receive drained oil.
2. Turn the drain plug (P) slowly to avoid splashing oil on
yourself, and drain oil.
3. Check the drained oil and if it contains an unacceptable
amount of metal particles or foreign matter, contact us
or our sales service agency.
4. Install the drain plug (P).
5. Using a filter wrench, turn the filter cartridge (1) to the
left to remove it.
6. Clean the filter base and reinstall a new filter cartridge
after coating its packing and threaded portion with clean
engine oil (or lightly with grease).
NOTES
Make sure that old packing is not attached to the filter
base. If the old packing remains attached, it can cause oil
leakage.
7. When reinstalling the filter cartridge, tighten it for 1/2 to
3/4 turns after the packing face comes in contact with
the sealing face of the filter base.
8. After replacing the filter cartridge, fill the oil through the
oil inlet (F) to the level within the range H-L marked on
the level gauge (G).
9. Start and run the engine at idle for approx. 5 minutes
and stop the engine. Refer to “Operation 3.1.2
Pre-operation Inspection [2] Inspection of Oil Level and
Refilling Oil in Engine Oil Pan” to check that the oil level
is between H and L on the level gauge.
