MAINTENANCE
Breather Filter Inspection
Four-cycle ATV engines are equipped with a breather filter. The
in-line filter is similar in appearance to a fuel filter, and is visible
on the left side (Location A).
In-line breather filters can be installed in either direction.
Breather Hose
1. Be sure breather line is routed properly and secured in
place.
CAUTION: Make sure lines are not kinked or
pinched.
NOTE: In-line breather filter service life is extended
when the foam air box pre-filter is in place and
maintained properly. Never operate the engine without
the pre-filter.
Recoil Housing
• Drain the housing periodically to remove moisture.
• Drain the recoil housing after operating the ATV in
very wet conditions. This should also be done before
storing the ATV. The drain screw is located at the
bottom of the recoil housing. Remove the screw with a
10 mm wrench. Reinstall screw once housing has been
drained.
• CAUTION: Make sure the manual start handle (B) is
fully seated on the recoil housing, especially when
travelling in wet areas. If it is not sealed properly, water
may enter the recoil housing and damage components.
• Water will enter the recoil housing if the starter handle
(B) is disengaged from the rope guide when under
water.
• After travelling in wet areas the recoil housing and
starter should always be drained completely by
removing the recoil.
• Do not open the crankcase drain unless the engine has
ingested water. Some engine oil will be lost if crankcase
drain is opened.
• If recoil handle (B) seal has been damaged, the handle
should be replaced.
