10 IDENTIFYING CONTROLS
The diagram B/8 illustrates the various working positions (A,B,C,D) referred to in the following pages describing how to use the tire changer.
Use of these positions ensures greater precision, speed and safety for those using the machine.
The mobile control unit (fig. C) enables the operator to work at any position around the machine. On this mobile control unit the follow-
ing controls are located:
-The lever (8, fig. C) which in position [a] lifts the chuck arm and in position [b] lowers it; in position [c] moves the tool holder arm and the
sliding table towards the self-centering chuck and in position [d] moves them away.
Note: in order to memorise this operation, there is a hole in the lever guard corresponding to position c.
-The chuck switch (9, fig. C) when moved upwards, opens the arms of the self-centering chuck (LOCKING), and when moved down,
closes the arm of the self-centering chuck (UNLOCKING).
-The pedal (10, fig. C) when pressed on the left or right side rotates the self-centering chuck in the same direction as shown by the ar-
rows placed on the foot pedal.
Both rotations can be made with two different speeds, just placing the selector (12, fig. B/6) in position 1 for getting slow rotation and in
position 2 for fast rotation of the turntable
The tire changer also has:
Handle (19, Fig. D) to tip the tool carrier arm (14, Fig. 4) from its work to its non-working position and vice-versa.
Handle (15, Fig. D) for alternative use of the bead-losening disk (17, Fig. D) or the hooked tool (18, Fig. D). Pressing the emergency stop
button (12, fig C) will stop any operation in course
