7.3.6 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.
In
order to carry out this check it is necessary to raise the front wheels off
the ground (for machines equipped with levelling outriggers is sufficient
to lower the levelling outriggers) and verify that the axle remains in
position when stressed.
If you notice a movement of the axle, it is necessary to proceed to the
elimination of the air present in the cylinders in the following manner:
Unscrew cap (
A
) one of the two cylinders of the oscillating axle or, in
the absence of the cap, loosen the four captive screws valve (
B
).
Carry out the drive operation by bringing the two oscillating
axle cylinders to end stop several times, until there is only oil
leaking out of the cap of the locking valve.
Once purging has been completed, screw cap (A) or tighten the
screws ( B ) and check the oil level in the tank.
WARNING!
THIS OPERATION OUGHT TO BE CARRIED OUT SIMULTANEOUSLY BY TWO OPERATORS: ONE IS TO
DRIVE THE MACHINE, THE OTHER IS TO CHECK THE OPERATION AND COLLECT THE LEAKING OIL.
THIS OPERATION SHOULD BE CARRIED OUT IN ROOMS THAT ALLOW THE OIL LEAKING FROM THE
CYLINDERS TO BE RECOVERED.
AS THIS OPERATION IS VERY IMPORTANT IT IS TO BE CARRIED OUT BY SPECIALIZED TECHNICIANS
ONLY.
