Depending on the model, the machine is
equipped with 2 or 4 control levers.
Function:
With 2 control levers:
The front attachment frame is raised
and lowered via the left control lever. If
the lever is pushed all the way to the
front, the front attachment frame is in
float position.
Note: This float position is needed
when attachments are guided along the
ground (e.g. snow plow). It is also part
of the safety equipment and must be
switched on for hydraulic operation of
other attachments.
The right control lever is used to raise
and lower the attachment.
With 4 control levers:
The two centre levers (optional) are
used to control the front-mounted at-
tachments.
The right control lever is used to control
rear-mounted attachments.
Throttle to the rear: Low speed
Throttle all the way to the front: High
speed
Note: To drive and work, position the
throttle all the way in the front (high
speed); the drive speed is controlled via
the accelerator pedal.
The accelerator pedal determines the driv-
ing direction as well as the speed of the ma-
chine.
Press the accelerator pedal to the front:
Machine will move forward.
Press the accelerator pedal to the rear:
Machine will move in reverse.
The harder the accelerator pedal is
pressed, the faster the machine will
move. The final speed is determined by
the position selected with the speed
preselector.
If you release the accelerator pedal, the
machine is braked using all driven
wheels and will come to a stop.
In case of a change of direction (for-
ward/reverse), let the machine come to
a brief stop.
There are 3 different speed ranges; the ma-
chine should be at a standstill while switch-
ing between them.
–Top position: High speed range
–Centre position: normal speed range
–Bottom position: low speed range
몇Danger
Activate the emergency brake prior to leav-
ing the machine.
With the cruise control, the accelerator
pedal can be locked in any position at any
speed.
Switching on the cruise control: Use the
accelerator pedal until the desired
speed is reached. Then, press the
cruise control switch on the dashboard.
Release the accelerator pedal, the ma-
chine will maintain the set speed.
Switching off the cruise control: The
cruise control can either be switched off
via the switch or by pressing the inch-
ing/brake pedal.
The inching pedal regulates the speed in all
work modes. Also functions as a brake.
Use the inching pedal to reduce the
driving or working speed.
