Lubrication
Chaincase Oil
Check the chaincase oil level weekly and before any long trips.
Place the machine on a level surface.
Remove the dipstick (A) and read the oil level. The oil level should be
between the SAFE marks on the dipstick. Add Polaris chaincase oil
through the dipstick opening if needed. Do not overfill. See page 128
for the part numbers of Polaris-recommended products.
Flush the chaincase after the first 500 miles, then every 1000 miles or
seasonally. Clean the magnetic plug (B) whenever checking or
changing lubricant.
