INSTRUMENTS AND CONTROLS 4 JOYSTICK STROKE ADJUSTING KNOB (only for the version with servo-assisted backhoe) q The adjustment of the joystick stroke must be carried out before starting work and with the machine completely 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 inclined, reduce the stroke by turning the knobs (4) clockwise, 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 position is within the desired values. 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 adjusting screw (F) clockwise. To decrease the distance between the joystick and the rear window, turn the adjusting screw (F) counterclockwise. 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 position. q After adjusting the stroke of both joysticks, make sure that all fastening elements are correctly tightened. 116 WARNING
