11. VENTING AIR IN HYDRAULIC CIRCUITS
NOTES
For details of starting engine, refer to the description under "OPERATION 3.3 STARTING
ENGINE". Refer to the description under the section of starting, stopping and changing
direction of the Machine in the Operation volume as required.
CAUTION
•
After completion of air venting, stop the engine once to allow it to be standing still for
5 minutes, and then start the engine again. This process allows the air bubbles
entrapped in oil tank to vent into the atmosphere.
•
After completing the operation, check for any oil leakage, and cleanly wipe off spilt oil.
[1] VENTING AIR IN PISTON PUMP
CAUTION
Running the pump without filling the pump case with hydraulic will oil cause early
damage of pump after giving off abnormal noise. Be sure to exercise the air venting.
1. Loosen the fitting (1) of port D of the pump to check if
oil is oozing out through the fitting (1) (air venting
completed).
2. After completion of air venting, tighten the fitting (1) of
the port D of the pump.
[2] VENTING AIR IN CYLINDER
CAUTION
Revving the engine at the outset and allowing the cylinder to move to the stroke end
may damage the piston packing or other parts because of air inclusion in the cylinder.
1. While allowing the engine to run at idle and not allowing the cylinder to reach the stroke end
(stopping it approximately 100mm before the stroke end), repeat telescoping for 4 to 5 times.
2. Then, allow each cylinder to travel to their stroke end 3 to 4 times.
3. Again allow each cylinder to travel to their stroke end 4 to 5 times to vent the air thoroughly.
