Manual Adjustment
1. Park the machine on a flat, level surface. Ensure
machine is level and tires are filled to rated pressure.
NOTE: Ensure switch mounting bracket is level and securely
attached.
2. Level the base of the indicator by tightening the
three flange nuts through approximately one quarter
of its spring travel. DO NOT ADJUST THE “X” NUT
DURING THE REMAINDER OF THE PROCEDURE.
3. With the electrical connections complete, using bub-
ble level on top of indicator, slowly tighten or loosen
the three flange nuts until indicator is level.
4. Individually push down on one corner at a time;
there should be enough travel to cause the switch to
trip. If the switch does not trip in all three tests, the
flange nuts have been tightened too far. Loosen the
“X” nut and repeat steps (2). through (4).
