Unloading vehicle Unloading vehicle
Operate very carefully when filling the grapple to
avoid damaging stakes and their attachments on
the vehicle.
1 Approach the vehicle which is to be unloaded
with a raised and fully open grapple.
2 Tilt the grapple forward and lay it down over the
load.
Close the clamping arm and begin to tilt slightly
upward. Then repeat alternate closing and upward
tilting of the grapple until it is full.
NOTE! NOTE!
Operate carefully when unloading a vehicle,
especially when there are only a few logs left. If the
grapple should grip around the far edge of the
platform this could lead to damage.

1 Make sure that each log lies correctly in the
grapple to avoid “crows nest”.
2 Approach the vehicle to be loaded while at the
same time raising the attachment so that the
logs clear the stakes.
3 Lower the grapple until it is level on the bunks or
the platform and deposit the bundle against the
stakes on the far side.
4 Open the clamping arm fully and carefully
reverse out.
Stacking Stacking
For machines with Boom Suspension System it is
recommended that speed-dependent function
should be selected. The precision increases and
the risk of "crows nest" reduces.
1 Keep the grapple as near the stack as possible
to prevent logs falling down.
2 Tilt the grapple slightly forward.
3 Carefully open the clamping arm fully so that the
logs start to roll out of the grapple.
4 Then open the clamping arm completely and
reverse carefully while lowering the grapple and
holding back falling logs.
The grapple's counterhold can be used as heel
kick-out and therefore you do not have to tilt the
grapple forward. The machine's lifting height is
