Lower the digging head until the points of the spades are approx. 20 cm (8”) above the
ground. The digging head should be close to the truck without touching the truck.
3.2.3 Now the gate of the digging head must be unlocked.
control panel, lever. 1, gate lock ▲"unlock".
Then the gate must be opened:
control panel, lever 2, LH gate ▲"open".
control panel, lever 3, RH gate ▲"open".
3.2.4 In case low branched trees have to be transplanted, the working height of the digging
head can be reduced by folding out the spade towers. Each spade tower is controlled
individually.
control panel, lever 6, preselect: folding out spades
– LH rear / front
control panel, lever 7, folding out spades
– in / out
control panel, lever 8, preselect: folding out spades
– RH rear / front
3.2.5 Now the rear stabilizers must be retracted:
control panel, lever 9 a
nd 10, ▲"up".
IMPORTANT: The truck must not move prior to having
retracted the rear stabilizers!
Reverse the truck until the tree is positioned in the center of the circular
frame of the digging head, then close the gate:
control panel,
lever
2, LH gate ▼"close".
control panel,
lever
3 RH gate ▼"close".
Now the gate must get locked:
control panel,
lever
1
, gate lock ▼"lock"."
To ensure that the machine is digging only when the gate is locked, a safety switch
has been installed. If the gate is not locked properly, a red indicator light at the
panel (section 3.1.1, number 16) will flash and the spades do not move. This
malfunction is probably caused by a branch or some other object obstructing the
gate lock. Remove the obstruction and try again.
IMPORTANT: Locking the gate before starting with the digging operation
is of utmost importance and must never be omitted!
If the gate is not locked properly, the frame will get bent when
digging!
Next the digging head is lowered by means of joystick 20 or 21 resp.
main lift arm
▼"down" and/or articulated lift arm ▼"down"
until it is resting on the ground. Adjust
digging head with j
oystick 20 digging head rotation
◄
►"in/out"
until the circular frame is
in a horizontal position. Check again if tree is in the center of the frame and readjust, if
necessary.
Now the spade towers must get folded back again.
