MOUNTING THE MAST
7.5.1
Mounting the Trestle
Select backstay cylinder operation.
Using the control levers, retract backstay cylinders and slightly raise the mast.
CAUTION
Risk of damaging the rig!
With the trestle folded to the front, the mast may be raised by max. 20°.
Mount transport supports (4).
Using the control levers, extend backstay cylinders and put down the mast on the
ground.
NOTE
Underpin the transport supports with timber if the ground is soft.
Open up the mechanical swing lock.
Release the swing brake.
Extend backstay cylinders (1) by control levers, until trestle (2) can be mounted to
machine with pin (3).
Install the pin and secure it.
Retract backstay cylinders and raise the mast enough to enable the transport sup-
ports (4) to be removed from the lower mast section.
