1. Remove undercover (1) at the bottom of the machine,
then set the container under drain valve (P) on the left
side of the machine to catch the oil.
2. Loosen drain plug (P) and drain the oil. Be careful not to
get oil on yourself.
3. Tighten drain plug (P).
4. Open the pump room on the right side of the machine,
then using the filter wrench, turn filter cartridge (2) to the
left to remove it.
5. Clean the filter holder, fill the new filter cartridge with
clean engine oil, coat the packing surface and thread of
the filter cartridge with engine oil (or coat it thinly with
grease), then install the filter cartridge to the filter holder.
REMARK
Check that there is no old packing stuck to the filter holder. If
there is any old packing remaining, it will cause oil leakage.
6. When installing, tighten until the packing surface contacts
the filter holder, then tighten a further 3/4 turn.
7. After replacing the filter cartridge, add engine oil through
oil filler port (F) so that the oil level is between the H and
L marks on dipstick (G).
8. Run the engine at idling for a short time, then stop the
engine and check again that the oil level is between the H
and L marks on dipstick (G).
