DRIVE CONTROL
FUNCTION OF DRIVE PEDALS
When thinking about the function of the two drive pedals, they should be
compared to gears, not to a conventional throttle pedal. The
drive pedal
in a way
shifts on a higher gear
the more the pedal is pressed. Therefore
you shouldnt press the pedal more when the engine starts to struggle.
Pressing the pedal just causes the engine to stop.
When you want to have a high pulling force:
1. Use high engine revs
2. Select a relatively slow drive speed with the drive pedal. That is: press the
pedal only lightly (= select a low gear). This way the full output of the
hydraulic system and the engine can be taken out.
AVANT 200
series loaders are equipped with a hydrostatic drive system,
there is a variable displacement hydraulic pump in the drive circuit. The oil
flow of this drive pump is steplessly adjusted with the two drive pedals. The
drive pedals act in a proportional way to control the drive speed and power
available at the drive motors.
This hydrostatic drive system has different operating characteristics to a
mechanical drive. To get maximum pushing power push the pedals lightly -
for higher travel speed push the pedal harder.
Driving of the machine
is controlled with the drive pedals
as follows:
Select the revs of the engine with the
hand throttle lever
on the control
panel. The basic rule is: use lower revs for lighter work and higher revs for
hard work.
If you want to
drive forward
, press gently on the
right
drive pedal until
the machine starts to move slowly. The desired drive speed is selected with
the drive pedal: the more the pedal is pressed the faster you will travel.
When you
wish to stop
gently release the pedal by lifting of your foot, and
the machine will slow and stop.
Drive backward
is controlled with the
left
drive pedal in the same way as
drive forward: the more the pedal is pressed the faster you will travel.
When you have learned how to drive on low speed, increase speed gradually
and learn how to drive with higher drive speeds.
