6. Repeat steps 3 thru 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 thru 7.
Voltmeter Adjustment
1. Park the machine on a flat, level surface. Ensure the
machine is level and the tires are filled to the rated
pressure.
2. If the engine is not running, turn the ignition switch
to ON.
3. Connect the black lead of the voltmeter to ground
and the red lead to the yellow wire protruding from
the pot on the bottom of the sensor.
4. Adjust the leveling nuts to obtain the highest possi-
ble voltage reading.
5. Check voltage at the trip point in all four directions. If
the voltage reading is not symmetrical, repeat step 4
above.
2.14 LIMIT SWITCH ADJUSTMENTS
Boom Limit Switch
The boom limit switch is located on the left side of the
base section of the boom. The switch will activate when
the boom is extended past a set point with the axles
retracted. When activated, the switch cuts out Telescope
Out and Lift Up. Adjust the limit switch to trip at 3 meters of
boom extension.
Horizontal Cut-Out Switch
The horizontal cut-out switch is located on the right side of
the boom at the boom pivot pin. When activated, the
switch cuts out the High Engine, High Drive, and 2 Speed
functions. On machines built to Italian specifications, the
switch also cuts out the Drive function. Adjust the switch
to activate when the boom reaches horizontal.
Drive Cut-Out Switch - Dutch Specifications
On machines built to Dutch specifications, a drive cut-out
switch is located on the left side of the boom at the boom
pivot pin. When activated, the switch cuts out the Drive
function. Adjust the switch to activate when the work plat-
form reaches a height of 8 meters.
