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 reservoir 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. Tight-
en 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 seconds to make sure all air is out of
the system.

ling the engine, and observing the oil
