Air filter maintenance
Please inspect and clean the air filter on a regular basis. If
the filter has not been cleaned for a longer period, this will
have influence on the engines power take-off and the
exhaustion.
1. Clean around the air filter before it is removed.
2. Carefully remove the paper filter and check it. Brush
it with a soft brush. If it is very dirty, it must be
changed. Take care that no dirt gets into the intake
of the engine.
3. Wash the black foam element on the right side in
warm soapy water.
4. Press the water out of the foam element and let it
dry. Put a few drops of SAE-30 oil on the filter to
moisten it lightly with oil. Carefully squeeze out any
surplus oil. Remount the element.
5. Check that all parts are fitted correctly and the cover
closed as shown in the picture.

Storage

chassis number should only be cleaned with a
damp cloth to avoid unnecessary wear. Avoid using
a high-pressure washer during cleaning.

Wipe the tiller with a damp cloth so that all surfaces
are clean. Wipe the surfaces down with an oily cloth
to prevent rust.
