  • Page 4: Introduction

    INTRODUCTION The purpose of this manual is to provide the owner and operator with effective and safe instructions for the use and maintenance of the wheel balancer. Follow all of the instructions carefully and your machine will assist you in your work and give long-lasting and efficient service, in keeping with manufacturer traditions.

  • Page 5: Transport, Storage And Handling

    TRANSPORT, STORAGE AND HANDLING Handling and manoeuvring before installation The basic wheel balancer packaging consists of 1 wooden crate containing: - the wheel balancer (Fig.7) - equipment; - the wheel guard and corresponding mounting tube (C, Fig.4a - D, Fig. 4a). Before installation, the wheel balancer must be shipped in its original packaging, making sure that the machine is maintained in the position indicated on the outer packaging.

    3. ENTERING WHEEL DIMENSIONS (ALU1P AND ALU2P PROGRAMMES EXCLUDED) Wheel data entry for wheel balancers without an ultrasonic sen- sor or outer mechanical sensor The machine allows for the diameter and distance values to be entered automati- cally; the width value can be entered using the keypad.

    5. ENTERING DIMENSIONS IN THE MOTORCYCLE PROGRAMMES The operations described below are valid if the motorcycle setting (byke) has been activated in the "vehicle type" set up. - Fit the appropriate extension on the inner measur- ing arm, specifically extension A on machines with no weight holder or extension B on machines with weight holder (Fig.16).
  • Page 33 CAUTION Never raise the guard before the wheel has come to a stop. CAUTION If the wheel keeps spinning permanently due to a fault on the machine, switch off the machine using the main switch or disconnect the plug from the power supply board (emergency stop) and wait until the wheel stops before raising the guard.
  • Page 34 CAUTION Check that the system which fits the weight to the rim is in optimum condition. A weight which is not fitted properly or correctly may come off as the wheel rotates, thus creating a potential danger. Pressing the button while the wheel is moving interrupts the wheel spin before time and the A STP message is displayed.

  • Page 35: Applying Balancing Weights

    • Manually applied adhesive weights with laser device enabled (if provided) - Select the first side to be balanced. - Turn the wheel until the central element of the corresponding position indicator lights up together with the laser line. - Apply the indicated balancing weight in the position on the rim corresponding to 6 o'clock.
