MAINTENANCE
Rear Suspension Lubrication
Lubricate the suspension pivot shafts with POLARIS All Season Grease
at the intervals outlined in the Periodic Maintenance Table beginning on
page 99 and before seasonal storage. When operating in heavy, wet
snow conditions, lubricate every 500 miles (800 km).
Lack of lubrication will adversely affect your ride and the life of the
suspension. For more information about suspension lubrication and
adjustments, see your POLARIS dealer.
