6.9 Speed potentiometer
6.9 Speed potentiometer
Fig. 103 Speed/torque
potentiometer
The Speed Potentiometer (1) is located on the left armrest
panel, see 4.4
Left arm rest panel functions , page 56.
The Speed Potentiometer affects the angle of the
hydrostatic pump, which in turn affects the speed and
traction. You will get maximum traction when the Speed
Potentiometer is adjusted to make the machine move
slowly. Changes to the Speed Potentiometer setting can
be done while the machine is operating with a heavy load.
6.10 Drive pedal
The drive pedals (front, see 4.2 Functions at the steering
wheel panel , page 54) and rear (see 4.7 Functions at the
rear panel , page 63) affect both the control system’s
operating revs and the machine’s driving speed in the
following way:
• if the crane controls are not activated, the drive pedal
functions like a regular accelerator pedal.
• if the crane controls are being used, the preset
operating revs are active (e.g. 1300 rpm): when the
Drive pedal is activated, it operates like a speed control.
In this mode, it interacts with the speed potentiometer,
see 4.4
Left arm rest panel functions , page 56, in such a
way that the machine’s maximum speed corresponds to
the set value on the speed potentiometer. If the Drive
pedal is pressed even further, not only will speed
increase, so too will engine revs.
