Polaris 120 Owner's Manual For Maintenance And Safety page 58

Maintenance
Careful periodic maintenance will help keep your vehicle in the safest,
most reliable condition. Inspection, adjustment and lubrication of
important components are explained in the following chart and in the
maintenance section of this manual.
Service and adjustments are critical. If you're not familiar with safe
service and adjustment procedures, have a qualified dealer perform
these operations.
NOTE: The following chart is a guide based on average riding
conditions. You may need to increase frequency based on
riding conditions. When inspection reveals the need for
replacement parts, we recommend the use of genuine
Polaris parts, available from your Polaris dealer.
