12. CORRECT OPERATIONS CHECKS
Before using the tyre changer, a number of checks should be made to ensure it works correctly. CAUTION: The operations
described here should be done with the tool carrier arm in its non‐working position. First, use lever (15, picture F8.3) to tip
the arm to this position.
Do not move your face close to the tool carrier arm when you release it to tip it as needed.
1. Move the joystick (8, picture F8.2) up (A): the spindle carrier arm (2, picture F8.1) should lift; move the joystick down
(B): t h e a r m s h o u l d l o w e r ;
DANGER!
When the spindle carrier arm is lowered there is always a potential for crushing anything in its movement range.
Always work from the position given in the instructions keep well out of the working range of the various moving arms.
Move the joystick towards the left (C): the tool carriage and the mobile platform (13, picture F8.3) should move
towards the spindle (3, picture F8.1); move the joystick towards the right (D): the carriage tool and platform should
move away from the spindle.
2.
Turn switch lever (9, picture F8.2) towards the top: the spindle arms (3, picture F8.1) should open; move the lever
down and the spindle arms should close.
DANGER!
When the spindle arms open or closed, there is always a potential for crushing anything in their movement range.
Always work from the position given in the instructions keep well out of the spindle's working range.
3.
Press the right pedal (10, picture F8.2): the spindle (3, picture F8.1) should turn clockwise; press the left pedal: the
spindle should turn anticlockwise.
4.
Check to be certain the hydraulic circuit is working correctly:
Move the switch lever (9, Fig. F8.2) towards the top until the spindle arms are fully extended.
Hold the switch lever in this position (top) and check if the pressure shown on the gauge on the swivel fitting is 130 Bar
±5%.
If the pressure shown in not as indicated here, DO NOT USE the tyre changer and call your nearest Assistance
Centre.
13. USE
13.1 Wheel locking
In locking the wheel make sure that clamps are properly positioned on the rim, so as to
prevent the tyre from falling.
1.
Take the mobile control unit to work position B.
2.
Pull the tool‐holder arm into the up‐right position.
3.
Operating from the mobile control center, move the sliding table away from the self‐centering chuck and
place the wheel in vertical position on the sliding table.
This operation can be extremely dangerous. Do it manually only if you are certain you can
keep the wheel balanced. For large and heavy tyres an adequate lifting device must be
used.
4.
Continuing to operate from the mobile control center, lift or lower the arm in order center the self‐centering
chuck relative to the rim.
