* Gap setting should be made with “GO-NO-GO” type feeler gauge. Lower value must not trip switch. Upper value must trip switch.

Table 2

After the machine has been properly installed, the vibration switch gap must be measured before conducting the Control Function Test. Locate the gap found between the vibration switch and the machine structure. Refer to Figures 1, 2, 3, 4 and 5. To check the gap setting of the switch, proceed as follows:

1.Remove the front panel on 18-50 models. Remove the rear panel on 60-80 models. Remove the top cover on the 125 model. The switch can be seen inside the bottom right corner of the A- frame, mounted on a bracket. Refer to Figures 1, 2, 3, 4 and 5.

2.Measure the gap distance when the switch is in both the open and closed positions. The specifications should be at the minimum switch gap setting when the switch is open and at the maximum switch gap setting when the switch is closed. If these distances are not correct, adjust the balance switch to these specifications.

NOTE: The standard position of the switch is open, or non-tripped.

3.Tighten nuts on switch extension after adjusting the gap. Measure the gap distance to verify accurate setting.
