PAPER ELEMENT SERVICE (STANDARD TYPE)
Check the paper element every 100 hours of operation
(more often under extremely dusty or dirty conditions).
Replace the element as necessary.
Refer to the following steps and to Figure 13:

cleaner cover (Figure 13), and remove the cover.
2. Remove the wing nut, element cover, seal and air
cleaner element.
3. Remove the precleaner (if so equipped) from the paper
element.

bent, or damaged element with a new element as
prescribed by the engine manufacturer. Handle new
elements carefully; do not use if the sealing surfaces
are bent or damaged.
5. Reinstall the seal, paper element, precleaner, element
cover, flat washer and wing nut.

Air Cleaner - Components to Check
Whenever the air cleaner cover is removed, or the paper
element or precleaner is serviced, check the following:
„ Air Cleaner Element Cover and Seal — Make sure
the element cover is not bent or damaged. Make sure
the wing nut, washer and seal are in place to ensure the
element is sealed against leakage.
„ Air Cleaner Base — Make sure the base is secured
tightly to carburetor and not cracked or damaged.
„ Breather Tube — Make sure the tube is installed to both
the air cleaner base and the breather cover.

proceed as follows:
1. Remove the air cleaner components as described
previously.

breather tube through the base.
4. Remove the tube from under side of base if necessary.

dusty or dirty conditions):
1. Remove the blower housing and other cooling shrouds.
2. Clean the cooling fins and external surfaces as necessary.
