Group 4 Bleeding Air

SECTION 1 GENERAL

W1-4-1-2

Bleeding Air from Hydraulic System

Bleed air from the hydraulic system as follows when

hydraulic oil has been drawn, the suction filter and

suction pipe have been replaced, or the pump device,

swing motor, travel motor, cylinders have been removed/

installed.

IMPORTANT: If air is accumulated inside of the pump

and if the engine starts in lacking of hydraulic oil,

the pump may be damaged.



Bleeding Air from Pump



Remove the air bleed plugs on top of the pump. Add

hydraulic oil to the pump.



After the pump is filled with hydraulic oil, temporarily

tighten the plugs. Then, start the engine and run it at

slow idle speed.



Slightly loosen the plugs and bleed air from the

pump until hydraulic oil comes out from the gap.



After bleeding all air, securely tighten the plugs.

IMPORTANT: If air is accumulated inside of the motor

and if the engine starts in lacking of hydraulic oil,

the motor may be damaged.



Bleeding Air from Travel Motor, Swing Motor



Remove the air bleed plug (top) from the travel

motor and swing motor. Fill the motor case with

hydraulic oil.

IMPORTANT: If air is accumulated inside of the

cylinder and if the cylinder is operated suddenly

in lacking of hydraulic oil, the seal may be

damaged or the cylinder may seize.



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 operation

(never fully stroke the cylinders during initial

operation stage).



As the pilot circuit has an air bleed device, air in the

pilot circuit will be bled while performing the above

operation for approx. 5 minutes.



Reset the front attachment in position for checking

hydraulic oil level.



Stop the engine. Check hydraulic oil level. Replenish

hydraulic oil if necessary.
