3. With the electrical connections complete, slowly
tighten one of the “Y” nuts until the circuit is closed
and the light on the Platform Control Console illumi-
nates.
4. Slowly back off the nut, counting the number of
turns, until the circuit is again closed and the light
again illuminates.
5. Divide the number of turns determined in step 4 in
half. Tighten the nut this many turns. The line deter-
mined by this nut and the “X” nut is now parallel to
the ground.

6. Repeat steps 3 through 5 for the remaining “Y” nut.
The switch is now level.
7. 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 3 through 7.
Voltmeter Adjustment
1. Park machine on a flat, level surface. Ensure
machine is level and tires are filled to rated pressure.
2. If engine is not running, turn ignition switch to ON.
3. Connect black lead of voltmeter to ground and red
lead to yellow wire protruding from pot on bottom of
sensor.
4. Adjust leveling nuts to obtain the highest possible
voltage reading.
5. Check voltage at trip point in all four directions. If
voltage reading is not symmetrical, repeat step 4
above.
