MAINTENANCE PROCEDURES
This section includes instructions for
basic maintenance procedures.

ways turn ignition switch to the
OFF position before performing
any maintenance and remove key.
WARNING
Should removal of a locking de-
vice be required (e.g. lock tab,
self-locking fastener, etc.) , always
replace it with a new one.
Engine Air Filter
NOTICE
Never modify the air in-
take system. Otherwise, engine per-
formance degradation or damage
can occur. The engine is calibrated
to operate specifically with these
components.
Engine Air Filter Replacement
Guideline
Engine Air filter inspection and replace-
ment frequency should be adjusted
according to riding conditions as it is
critical to ensure proper engine perfor-
mance and life span.
Engine Air filter inspection and replace-
ment frequency must be increased for
the following severe riding conditions:
– Riding on dry sand.
– Riding on dry dirt covered surfaces.
– Riding on dry gravel trails or similar
conditions.
– Riding in areas with high concentra-
tion of seeds or crop husks.
– Riding in severe snow conditions.
NOTICE
When riding in dusty con-
ditions or sand, the air box needs to
be cleaned before every ride.
NOTE: Riding in a group under these
conditions would increase even more
the air filter replacement frequency.
Engine Air Filter Removal
Open cargo box.
Unlatch air filter cover and remove air
filter.

RH SIDE OF VEHICLE, UNDER CARGO BOX
1. Air filter cover
2. Latches
3. Duck bill valve
The filter fits tightly over the outlet
tube and there will be some initial re-
sistance. Gently move the end of the
filter back and forth to break the seal,
then rotate while pulling straight out.
Avoid knocking the filter against the
housing.
Engine Air Filter Cleaning
Inspect the filter for any signs of leaks.
A streak of dust on the clean side of
the filter is a telltale sign. Replace filter
if there is any damages. Eliminate any
source of air leaks before installing a
new filter.
Clean engine air filter by tapping out
heavy dust from paper element, this
will allow dirt and dust to get out of the
paper filter.
NOTICE
It is not recommended to
blow compressed air on the paper
element; this could damage the pa-
per fibers and reduce its filtration
ability when used in dusty environ-
ments. If engine air filter is too dirty
and cannot be cleaned following the
recommended procedure, it should
be replaced.
