Air purging from oscillating axle locking cylinders
Once drive has been stopped, the axle locking cylinders are
locked in position thus increasing the machine stability.
Check that no air is present inside the oscillating axle
cylinders every year.
To carry out this check it is necessary to:
-
Remove the protection cylinder crankcases (
A
) of the
oscillating axle.
-
Unscrew the cap (
B
) of one of the two cylinders of the
oscillating axle;
-
Carry out the drive operation by bringing the two
oscillating axle cylinders to stroke position several times,
until there is only oil leaking out of the cap of the locking
valve.
-
Once purging has been completed, screw cap (
B
) and
check the oil level in the tank.
Fig.23
Attention! This operation ought to be carried out simultaneously by two operators: one is to drive the
unit, the other is to check the operation and collect the leaking oil.
This operation ought to be carried out in rooms that allow the oil leaking from the cylinders to be
recovered.
