Polaris 2010 99 Ranger Offroad Vehicle User Manual

Periodic Maintenance Schedule
Careful periodic maintenance will help keep your vehicle in the safest, most reliable
condition. Inspection, adjustment and lubrication intervals of important compo-
nents are explained in the following chart:
Maintenance intervals are based upon average riding conditions and a vehicle
speed of approximately 10 miles per hour. Vehicles subjected to severe use, such
as operation in wet or dusty areas, should be inspected and serviced more fre-
quently. If you are not familiar with safe service and adjustment procedures, have
a qualified dealer perform these operations.
Inspect, clean, lubricate, adjust or replace parts as necessary.
J CAUTION: Due to the nature of these adjustments, it is recommended that
service be performed by an authorized Polaris dealer. Do not attempt to perform
this work unless you are familiar with mechanical repair.

ine Polaris parts available from your Polaris dealer.
