MAINTENANCE
• Filter wrench
1.
Remove the cover (1) at the bottom of the machine.
2.
Take out the hose (2) from the toolbox and install it.
3.
Place the oil container just under the drain valve (P).
4.
Gradually lower the lever of drain valve (P) and drain the
oil, with care not to get splashed with the drained oil.
5.
After draining the oil, raise the lever to close the valve.
6.
Open the door on the rear left side of the machine.
7.
Turn the filter cartridge (3) counterclockwise by using the
filter wrench, and remove it.
8.
Clean the filter holder, 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 holder.
REMARK
Check that there is no old packing stuck to the filter car-
tridge (3). If there is any old packing stuck to it, it will cause
leakage of oil.

When installing, tighten until the packing surface contacts the seal surface of filter cartridge (3), then tighten
it further 3/4 to 1 turn.
