3.
Place a container to catch the drained oil just under the

Check the drained oil. If it contains much metallic powder
or foreign material, contact your Komatsu distributor.

6.
Open the engine side cover (2) on the left side of the ma-
chine.

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