Bleeding air from the hydraulic components
NOTE:
After bleeding air from the components, stop the
engine for five minutes and check there are no bubbles at
the surface of the hydraulic fluid in the reservoir.
Hydraulic pump
• Using a solvent, clean the periphery of the air bleed
plug. Loosen the air bleed plug, remove the plug if the
fluid does not flow.
• Fill the pump with new clean hydraulic fluid. Install and
tighten the air bleed plug.
• Start the engine and run it at low idle speed. Loosen
the air bleed plug on the pump. Tighten the plug when
air free fluid comes out of the bleed plug hole. Clean
the area completely.

Swing motor
• Start the engine and run it at low idle speed. Loosen the
drain port and make sure hydraulic fluid runs out. If nec-
essary, stop the engine and add oil via the orifice. Install
the plug without tightening, then start the engine and
run it at low idle speed, leaving it to run until oil begins
to run from the orifice. Tighten the air bleed plug com-
pletely. Swing the upperstructure at least twice com-
pletely to the right and twice completely to the left.
• After complete bleeding, stop the engine for five min-
utes then check that there are no air bubbles in the hy-
draulic reservoir.
