4.4 DRIVE PEDAL ADJUSTMENT
(
➤
Hydrostatic drive models)
This operation should be carried out every time
the rear axle, the pedal or the control rod is
removed in order to get the correct travel for the
pedal and to enable reaching the envisaged
speeds both forwards and in reverse.
A) Adjusting the pedal in the “neutral” position
The pedal position is to be adjusted starting with
the lever
(1)
of the hydrostatic unit in the “neutral”
position. This position «
N
» is easily recognised,
since it is held fast by a check ball.
The pedal
(2)
is in its best position when, with the
hydrostatic group lever
(1)
in “neutral”, the lower
edge of the front inclined section of the pedal itself
is at 85 mm from the metal edge of the footboard
(3)
.
This is obtained by opening the inspection hatch
beneath the seat and by turning the nuts
(4)
appro-
priately until the required measurement is reached.
Take care not to accidentally modify the position of
the lever
(1)
during the adjustment.
B) Adjusting the “neutral” position of the micro-
switch
IMPORTANT!
This is a very important adjustment for the cor-
rect operation of the safety devices for starting
and stopping of the machine during work.
The “neutral” position «
N
» is indicated by the
microswitch
(5)
of the cam
(6)
, which is reached by
the inspection hatch beneath the seat.
After having ensured that adjustment “
A
” has been
made correctly, with the pedal released and thus in
neutral position «
N
», slacken off the microswitch
fixing screws
(7)
and position it in line with the tip of
the cam, so that it remains pressed [see 7.1
By moving the pedal in the forward, neutral and
reverse positions, make sure that the push-button
clicks at every position change before the wheels
start moving.
