ADC SYSTEM (IF EQUIPPED)
ADC System Fluid Reservoir Location
The Active Descent Control reservoir is located by the
radiator fill cap under the storage box access panel.
Check the level and verify it is between the MAX and MIN
lines, Add only Polaris ADC fluid when required.
ADC Differential Hydraulic Circuit Fluid
Change
1. Make sure vehicle is parked on flat ground and
allowed to sit at least 30 minutes prior to bleeding
hydraulic circuit.
2. Thoroughly clean area around and on remote
reservoir and bleeder valves.
3. Remove reservoir cap and diaphragm assembly.
4. Make sure hydraulic oil inside reservoir is free of
debris. If any debris is found, use clean rag or suction
device to remove from the reservoir.
NOTE: Debris in reservoir may block porting and
produce inadequate bleeding of the system.
Decreased performance may be encountered with
inadequate bleed of the hydraulic circuit.
5. Begin the bleeding process by filling reservoir to
‘MAX’ line with clean Polaris Demand Drive PLUS
hydraulic fluid.
6. Locate bleeder valves found on either side of
differential and remove the protective caps.
7. Turn bleeder valves counter-clockwise to loosen.
Loosen bleeder screw slowly, allowing oil and any
trapped air to flow out of fitting.
IMPORTANT: Do not allow hydraulic fluid in reservoir
to drain below minimum fill line. Close bleeder valve
before oil level falls below minimum fill line. Refilling
empty reservoir will result in air pockets becoming
trapped.
NOTE: If empty reservoir is encountered, filling of
fluid is still possible. Verify air is not trapped before
proceeding with step 7.
8. Continue steps 6-8 on both sides in sequence until
clean fluid is seen when bleeding occurs.
9. Re-torque both bleeder valves to specification and
reinstall cover caps.
10. Fill reservoir with to a level midway between ‘MAX’
and ‘MIN’ fill lines. Verify no debris is found in
reservoir oil.
11. Replace reservoir cap securely and wipe clean any
residue.
