10 CONTROLS DESCRIPTION
The diagram B/8 illustrates the various working positions (A,B,C,D) referred to in the following pages describing how to use the tyre changer.
Use of these positions ensures greater precision, speed and safety for those using the machine.
The mobile control unit (C) enables the operator to work at any position around the machine. On this mobile control unit controls are
located:
- The lever (8, fig. C) : which in position position [a] lifts the chuck arm, and in position [b] lowers it; in position [c] moves the tool
holder arm and the sliding ramp towards the self-centering chuck, and in position [d] moves them away. Note: to memorize this last
operation, there is a hole in the lever guard corresponding to position [c].
- The lever (11, fig. C) : which in position [e] lifts the tool holder arm, and in position [f] in lowers it; in position [g] moves the tool carriage
leftwards, and in position [h] moves it rightwards.
- The chuck (5, fig. C) : when moved upwards, opens the arms of the self-centering chuck (locking), and when moved down close
close the arm of the self-centering chuck (unlocking).
- The chuck (9, fig. C) : when moved upwards turns the tool with disc towards the spindle, and when moved down ward, turns the tool
with the fingen towards the spindle ( 17 fig. D or 18, fig. D).
- The pedal (10, fig. C): when pressed on the left or right side rotates the self-centering chuck in the same directionas shown by the
arrows placed on the foot pedal. Both rotations can be made with two different speeds, just placing the selector (12, fig B/7) in
position 1 for setting slow rotation and in position 2 for fast rotation of the turntable. The tire changer also has a knob (15, fig. D) on the
tool arm, to unlock the double tool and help replacement of double tool with tubeless tires fitting/removing tower (on demand, ref.
# 9299274)
