4 JOYSTICK STROKE ADJUSTING KNOB
(only for the version with servo-assisted backhoe)
WARNING
q
The adjustment of the joystick stroke must be carried
out before starting work and with the machine complete-
ly still.
q
Before carrying out this operation make sure that the
servo control locking button is in locking position (LED
on) (see "3.3.2 pos. 12 - SERVO CONTROL LOCKING
BUTTON").
These knobs are positioned on the cab floor, on the front part
of each joystick support. They serve to adjust the stroke of
both joysticks in operating position.
For the adjustment, proceed as follows:
1 - After releasing the joysticks, lower them completely until
reaching the end of stroke. If they are excessively in-
clined, reduce the stroke by turning the knobs (4) clock-
wise, as indicated by the arrow (A).
If, on the other hand, it is necessary to increase the stroke
in order to obtain a more inclined position of the joysticks,
turn the knobs (4) counterclockwise, as indicated by the
arrow (B).
2 - After adjusting both joysticks, make sure that their posi-
tion is within the desired values.
If an adjustment should be necessary, proceed as follows:It is
also possible to adjust the stroke of the joysticks when they
are not used and are in vertical position. Once they have been
lifted, make sure that the safety distance between the joystick
(C) and the rear window (D) is sufficient to avoid any contact
(approximately 60 mm).
If an adjustment should be necessary, proceed as follows:
1 - To increase the distance between the joystick (C) and the
rear window (D), loosen the stop nut (E) and turn the ad-
justing screw (F) clockwise.
To decrease the distance between the joystick and the
rear window, turn the adjusting screw (F) counterclock-
wise.
Use a 17 mm hex wrench.
2 - Make sure that the distance complies with the safety limits
and tighten the stop nut (E) thoroughly.
IMPORTANT
q
The joysticks must always be turned moderately, trying
to accompany them until they reach the desired posi-
tion.
q
After adjusting the stroke of both joysticks, make sure
that all fastening elements are correctly tightened.
