MAINTENANCE
Oil Pump Bleeding Procedure
1. Fill the oil reservoir with Polaris injector oil.
2. Loosening the bleeder screw is only necessary when the oil
supply line has been disconnected from the pump or the oil res-
ervoir and supply line have been completely run out of oil. In
these cases, loosen the pump bleed screw one full turn. Allow
oil to flow from the bleed screw for five to ten seconds. Tighten
bleed screw. CAUTION: Never run the engine with the bleed
screw loose. Loss of oil will cause serious engine damage.
3. Start the engine and rotate the oil pump lever to its full open
position. With the engine at idle, hold the lever up for thirty se-
conds to make sure all air is out of the system.

Vehicles with 250 and 400 engines do not utilize a cable sleeve
jam nut. You will need to bottom the cable to the carburetor slide-
valve cap. Adjust at throttle cable adjuster near the throttle block.
