12 Control lever carrier and control functions

Lever (1) for the lifting function has four positions:
lifting,
neutral, lowering and floating.
Detent function, lifting / boom kick-out
Activation and selection of detent function lifting or
alternatively boom kick-out is done with the switch. The
control lever is then moved to max. lifting position.
Detent function lifting = the control lever remains in the
lifting position even after the lifting arms have reached the
max. lifting position, after which the control lever has to be
moved back to neutral by hand.
Boom kick-out = the control lever remains in the lifting
position until the lifting arms have reached a predetermined
height.
Thereafter it returns to neutral automatically.

Detent function floating position

Floating position is activated with the switch. Then the
control lever is moved forward to floating position.
Tilting lever (2) has three positions: rearward, neutral
and forward.

Detent function tilting (bucket positioner)

Activation of bucket positioner, is done with the switch.
Thereafter the control lever is moved to max. rearward
tilting position.
When the rearward movement of the attachment reaches a
predetermined position, the control lever returns to neutral
automatically.
Control lever (3) for the 3rd hydraulic function (optional
equipment)
• Double-acting hydraulic outlets, are used if the machine,
for example, is equipped with a timber grapple.
May also be used for hydraulically powered rotating attach-
ments. When such attachments are used, the control lever
may be equipped with detent function. The detent function
can quickly be disconnected with an emergency stop.
