Checking, Cleaning or Replacing the Air Filter
Operating the machine without a functional air filter may cause severe engine damage and will
void any warranty. • A dirty or oil saturated air filter will restrict air flow, which can be mistaken
as fuel system problems. Check the condition of the air filter before adjusting engine idle speed, where
applicable. • If the air filter is damaged (torn, broken, disintegrating), replace it.
The air filter is used to prevent dirt and other particles from possibly entering the engine and causing
internal damage to it. The air filter requires regular maintenance as per the maintenance schedule.
Air Filter Inspection and Cleaning
Inspect the air filter for dirtiness and debris, damage etc. Clean or replace the filter element as
necessary. To clean air filters:
•
For foam filters, wash the filter in warm water and mild detergent, then rinse and allow to dry.
•
For paper filters, use compressed air to blow particles from it, if possible. The air should be blown
from the engine side of the filter. Tapping the filter element against a hard surface and brushing the
pleats using a soft brush may also help remove debris from the filter.
•
For foam filters, place a few drops of clean engine oil on the filter then squeeze it a few times to
spread the oil through the filter material and remove any excess oil.
•
It is recommended to clean the air filter cover and air intake assembly of any dirt, cuttings etc.
To remove the air filter:
1. Remove (rotate left) the wing-nut (
A
) securing the air filter cover (
B
), then remove the cover from
the air intake assembly.
2. Remove (rotate left) the wing-nut (
C
) securing the air filter element (
D
), then remove the filter
element from the air intake assembly.
