Figure 2–15. Engine air cleaner components.
To change elements:
1. Unlatch the three retaining clips (Fig. 2–13) and
remove the air cleaner cover (Fig. 2–15).
2. Remove the wing nut and the primary element.
Inspect the element for damage. DO NOT clean or
reuse a damaged element.
3. Thoroughly clean the interior of the air filter canister
and vactuator valve.
4. If replacing the safety element, carefully slide it out.
Always discard this element and replace it with a new
element.
5. Slide the new primary element over the safety
element, making sure the sealing edge is flush with
the base of the air cleaner. Install and tighten the
wing nut securely.
6. Position the canister cover in place and secure it by
latching the three retaining clips.
Sky Trak recommends changing filters. If a replacement
filter is not available, carefully follow these procedures to
clean a primary element:
1. Remove loose particles from the filter with compressed
air [maximum 30 psi (2,1 kPa)] or water hose
[maximum 40 psi (2,8 kPa) without nozzle]. Rotate
and apply pressure from the inside of the element.
2. Soak the filter in non-sudsing detergent (such as
FM 1400) for at least 15 minutes. NEVER soak
longer than 24 hours.
3. Swish the filter around in the solution to remove
loosened dirt particles.
4. Rinse the filter from the inside out with a gentle
stream of water [less than 40 psi (2,8 kPa), without
nozzle] to remove all dirt and suds. If the inside of the
element has been contaminated with dirty water from
the soaking, rinse both sides.
5. Dry the filter before re-using. Circulate warm air at
less than 160°F (57°C). DO NOT use a light bulb to
dry the filter.
6. Inspect for holes or tears by looking through the filter
toward a bright light. Check for damaged gaskets or
metal parts. DO NOT re-use a damaged filter.
C. Air Intake System-Inspection
Inspect the intake piping for cracked hoses, loose
clamps, or punctures that can allow dirt or debris to enter
the combustion chamber. If dirt or debris is allowed to
enter the combustion chamber, it can severely damage
the engine. If necessary, tighten or replace parts to help
prevent air intake system leakage.
2.12.4 Optional Closed Cab Air Filters
The optional closed cab has two air filters, the recircula-
tion air filter (Fig. 2–16) and the fresh air intake filter (Fig.
2–17). Both of these filters require periodic inspection
and maintenance.
Recirculation Air Filter
Periodically remove and inspect the recirculation air filter
(Fig. 2–16) located directly below the seat. Gently hand
wash with water, a mild detergent may also be used if the
filter is saturated with dirt.
Figure 2–16. Periodically remove and inspect
the recirculation air filter.
