Air Filter
A
Your cultivator has been equipped with two (2) foam air
filters inside the air filter housing to prevent dirt and debris
from entering the engine.
Accumulated debris and dust in the air filter will reduce
engine performance, increase fuel consumption, and
increase the risk of damage. Inspect the air filters frequently
for dust and debris build-up, and clean the air filters
every 5 hours of operation (more frequently in dusty/dirty
conditions).
Both air filters should be cleaned by following these
instructions:
1. Before removing air filter cover, brush away any loose dirt
or debris on and around the filter cover.
2. Remove the screw securing the air filter cover. See
Figure 13.
3. Remove and clean foam filter.
• Light surface dust can readily be removed by
tapping the filter.
• Heavy deposits should be washed out in soap and
water. Squeeze out any remaining water and allow
the filter to completely dry.
WARNING
Never clean filter in gasoline or other flammable solvents.
4. Add a drop of thin oil to the filter and replace it.
