4.5 DRIVE PEDAL ADJUSTMENT
(
➤
Hydrostatic drive models)
This operation should be carried out every time the
rear axle, pedal or control rod is removed, in order
to get the correct travel for the pedal and to reach
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” posi-
tion. This position «
N
» is easily recognised, since it is
held fast by a check ball.
The pedal
(2)
is in the ideal position when the lever
(1)
of the hydrostatic unit is “neutral”, and the lower rub-
ber edge
(3)
on the reverse side is 24 -27 mm from
the footboard.
This is obtained by opening the inspection hatch
beneath the seat and by turning the nuts
(4)
appropri-
ately 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 7.11].
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.
