Active Descent Control (ADC) Fluid
Check and change the ADC fluid at the intervals outlined in the Periodic
Maintenance Chart beginning on page 76.
We recommend the use of POLARIS Demand Drive Plus Fluid for the
ADC unit. Maintain the fluid level between the minimum and maximum
marks on the reservoir. See page 131 for the part numbers of POLARIS
products.
NOTICE: Do not use brake fluid. Brake fluid will damage rubber components in
the hydraulic system.
Fluid Check
1. Access the reservoir under
the front box. See page 36.
2. View the fluid level in the
reservoir.
3. If the level is below the
minimum mark, remove
the cap and add the
recommended fluid.
4. Reinstall the cap.
5. Close and secure the front
box and cover.
