•
Bleeding Air from Hydraulic Circuit
•
After refilling hydraulic oil, start the engine. While
operating each cylinder, swing motor and travel
motor evenly, operate the machine under light
loads for 10 to 15 minutes. Slowly start each op-
eration (never fully stroke the cylinders during ini-
tial operation stage). As the pilot oil circuit has an
air bleed device, air trapped in the pilot oil circuit
will be bled while performing the above operation
for approx. 5 minutes.
•
Reposition the front attachment to check hydrau-
lic oil level.
•
Stop the engine. Recheck hydraulic oil level. Re-
plenish oil as necessary.
