1.
Remove the undercover (1) at the bottom of the machine.
2.
Place the oil container to catch the oil under the plug (P).
3.
Loosen drain plug (P) to drain oil. Do it slowly so that you
do not get splashed with drained oil.

6.
Turn the filter cartridge (3) counterclockwise by using the
filter wrench, and remove it.

REMARK
Check that there is no old packing stuck to the filter holder.
If there is any old packing stuck to it, it will cause leakage
of oil.
8.
When installing the new engine oil filter cartridge, apply
clean engine oil (or thin film of grease) to its packing and
thread part.
When installing the cartridge, tighten it until the packing surface contacts the seal surface of the filter holder,
then tighten it 1/2 of a turn.
