3 OPERATION

3.1 High Handler Sensor Adjustment

1. Remove the cover
2. Check the high handler bar sensor can move freely. If not, unscrew the M4 screw that fixes
the bar slightly (see "1", Figure 1).
3. Check the bar is aligned to the sensor OPT3, on the top of the electronic board. If not,
gently bend the bar to realign it.
4. Switch on the unit, push down the bar and check the LED LD3, on the top of the electronic
board remains off. If not, gently bend the bar upwards slightly (see "2", Figure 1).
5. During a compression cycle (at ambient temperature) check with a calliper the distance from
the heater carter and the top plate that supports the heater and bar is 15 +/- 0.5 mm (see
Figure 2). If not, alter the distance using the M3 screw and lock it with the M3 nut (see "3",
Figure 1)
