7.3 UNLOCKING AND LOCKING THE WINGS
The Zocon Greenkeeper has a mechanical lock on the hydraulic cylinders. This lock ensures
that the Greenkeeper's wings cannot unexpectedly unfold if the driver does something wrong
or if there is a fault with the hydraulic system. Thanks to this mechanical lock, the Zocon
Greenkeeper meets EU Directive 2006/42/EC.
Carry out the following to unfold the wings:
•
Fully lower the Greenkeeper to the ground.
•
Retract the cylinders so that the locking hooks are no longer pressurized.
•
From the tractor, pull the unlocking cord so that the unlocking hooks open. Make sure
the hooks remain open.
•
Once the locking hooks are open far enough, the cylinders can be extended so that
the wings can unfold.
•
The unlocking cord can be released now so that the hooks close again.
Carry out the following to fold up and lock the wings:
•
Retract the cylinders until the wings have been fully folded up (the unlocking cord
does not have to be pulled).
•
Carefully extend the cylinders until they are blocked by the locking hooks.
The locking hooks are now pressurized and can no longer unexpectedly open without
the cylinders being retracted.
