Items to be prepared
• Container to catch drained oil
• Filter wrench
1.
Remove the undercover just under the engine of the ma-
chine 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 rear right cover.
4.
Turn the filter cartridge (1) counterclockwise by using the
filter wrench, and remove it.
5.
Clean the filter head (2), fill the new filter cartridge with
clean engine oil, coat the thread and packing surface of
the new filter cartridge with clean engine oil (or thinly apply
the grease), then install it to the filter head.
REMARK
Check that there is no old packing stuck to the filter head
(2). If any old packing is stuck, it will cause oil leakage.
6.
When installing, tighten until the packing surface contacts the seal surface of filter head (2), then tighten it a
further 3/4 to 1 turn.
7.
After replacing the filter cartridge, open the engine hood
and fill with engine oil through oil filler port (F) to the mid-
point between H and L marks on dipstick (G).
8.
Run the engine at idle for a time, then stop the engine.
Check that the oil level is between H and L marks on the
dipstick.
9.
Close the rear right cover.
10. Install the undercover.
REMARK
When the ambient temperature is low, water or emulsified matter may stick to the dipstick and oil filler cap, etc.
or the drained oil may be milky white. However, if the coolant level is normal, it is not a problem.
There is no problem even if the emulsified matter cannot be removed completely after changing the oil.
