MAINTENANCE PROCEDURE
CHANGE OIL IN ENGINE OIL PAN, REPLACE ENGINE OIL FILTER CARTRIDGE
WARNING
Parts and oil are at high temperature immediately after the engine is stopped and may cause serious burns. Wait for the oil
temperature to go down before performing this operation.
Refill capacity: 35 liters (9.25 US gal)
Prepare a filter wrench
1. Remove cover (1) under the machine and put a container
under drain valve (P) to catch the drained oil.
2.
To prevent getting oil on yourself, lower the lever of drain valve
(P) slowly, drain the oil, then raise the lever to close the valve.
3.
Open the cover at the rear right, then use a filter wrench to turn
filter cartridge (2) to the left to remove it.
4.
Clean the filter holder, fill the new filter cartridge with clean oil, coat the thread and packing surface of the new
filter cartridge with clean oil (or coat it thinly with grease), then install it to the filter holder.
REMARK
Check that there is no old packing stuck to the filter holder. If there is any old packing stuck to the filter, it will cause
leakage of oil.
5. When installing, tighten until the packing surface contacts the seal surface of the filter holder, then tighten it a
further 3/4 to 1 turn.
