7.2.6. Air purging from oscillating axle locking cylinders
Once drive has been stopped and with raised platform, the
axle locking cylinders are locked in position thus increasing the
machine stability.
Check that no air is present inside the oscillating axial
cylinders every year.
To check for proper operation, proceed as follows:
▪
Remove the protection cylinder crankcases ( A )
of the oscillating axle.
▪
Unscrew the cap ( B ) of one of the two
cylinders of the oscillating axle.
▪
Let the machine perform some travelling until
the cylinder of the floating axle cylinders
reaches against end stop several times, and
until you see oil flowing out of the plug of the
check valve.
▪ Once purging has been completed, screw cap
( B ) and check the oil level in the tank.
