8 - 0121 3.7 - SPACER WD (option) When balancing very wide wheels (9”), the tyre may touch the casing of the balancing machine. Also it might not be possible, to position the gauge into the rim. To enlarge the distance of the rim, you should use the option WD/DC. Fit spacer WD on the adapter body, and secure it with the standard issue nuts. When centring the wheel with the cone on the inside, fit the other cone as a spacer to obtain spring thrust. Spring SPACER WD Spacer cone Centering cone 4 - CONTROLS AND COMPONENTS Fig. 5 4.1 - BRAKE PEDAL This pedal allows the operator to hold the wheel when fitting the counterweights. It must not be actuated during the measuring cycle. Fig. 6 4.2 - PNEUMATIC LOCKING PEDAL (Version P) This pedal allows releasing the device fastening the wheel on the adapter. Do not actuate this pedal during the machine cycle and/or when adapters other than the standard cone adapter are mounted. The pedal has two fixed positions: UP to release, DOWN to clamp the wheel. 4.3- AUTOMATIC DISTANCE AND DIAMETER GAUGE This gauge allows measurement of the distance of the wheel from the machine and the wheel diameter at the point of application of the counterweight. It also allows correct positioning of the counterweights inside rim by using the specific function (see 5.5.1) which allows reading, on the monitor, the position used for the measurement inside the rim (For calibration, see 7.4.1).
0121- 9 4.4 - AUTOMATIC WIDTH GAUGE (OPTION) This gauge allows measuring the rim of the wheel to be balanced in the point of application of the counterweight (see 5.3.1). 4.5 - AUTOMATIC WHEEL POSITIONING At the end of the spin, the wheel is positioned according to the unbalance on the outside or else according to the static unbalance (when selected). Accuracy is ±20 degrees. 4.6 - CLOCK CONTROL The balancing machine is provided with a clock whose back-up time, when the machine is switched off, is approx. 1 month. If the machine lies idle for a long period, when re-switching on for the first time, check the time and reset it if necessary (see 6.9). 4.7 - KEYBOARD Fig. 7 FUNCTION KEYS: they immediately select function indicated on the monitor Selection of special functions Confirm Starts measuring cycle Interrupts machine cycle NB: - Press the buttons with the fingers only: never use the counterweight pincers or other pointed objects. - When the beep signal is enabled (see section 6.8), pressing of any push button is accompanied by a "beep".
