Hydraulic System Bleeding and Filling Procedure
Air Motor Assembly Removal — continued
Attach hydraulic bleed unit to hydraulic fill fitting using hydraulic fitting coupler 622871. Remove
feed control needle valve 622026 and screw in circulating line. Attach air line to tool and turn
on air. Turn on circulating pump to circulate fluid. Depress trigger on tool several times to
remove air. Visually check circulating line for air bubbles. Check fluid indicator to see if tool is
full of fluid. Turn off circulating pump and disconnect hydraulic fitting coupler 622871 NOTE:
Do not damage spindles when disconnecting coupler. Disconnect circulating line and replace
feed control needle valve 622026. NOTE: If tool "lunges" during operation, it is due to trapped
air. Repeat bleed procedure described above.
