MAINTENANCE
Lubrication
The suspension pivot shafts should be lubricated with Polaris Premium
All Season Grease at 500 miles (800 km) initially, every 1000 miles
(1600 km) after that, and before off-season storage each year. Lack of
lubrication will adversely affect your ride and the life of the
suspension. For detailed information about suspension lubrication and
adjustments, see your Polaris dealer.
