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. Depending on model, the air filter cover (
A
) may be secured using a screw (
B
), or clips (
C
) into position.
If the cover has a screw, loosen it (rotate left) and remove the cover from the air intake assembly. If the
air filter cover is secured with clips, carefully release them – usually, you will need to press the tab of the
clip to release it. Carefully remove the air filter cover – some covers may hinge or have protrusions that
help locate it against the engine.
2. Remove the filter element (
D
).
To install the air filter:
1. Insert the air filter element, and ensure it is correctly positioned in relation to the air intake assembly as it
will seat and seal properly in one position only.
2. Re-install the filter cover, ensuring it is fitted properly against the engine and secure it with the screw
(rotate right and tighten by hand. Do not over-tighten), or clips.
