The Proximity switch (also known as the Boom Extend switch) controls machine functions based upon
whether the boom is extended or retracted. When the boom is retracted and the platform fully lowered, the
Proximity switch bypasses the Level Sensor and closes the circuit to the receiver. This allows high speed
travel, cage trim function, and axle float.

1. Lower the platform completely.
2. With the Platform/Chassis switch on CHASSIS, push the Level Sensor
base to test the alarm circuit.
3. If the alarm sounds;
a. elevate the platform and block the elevating assembly,
b. adjust the gap to 0,635 cm to 0,95 cm (1/4” to 3/8”),
c. lower the platform and re-test the level sensor. When the switch is prop-
erly adjusted, the alarm will not sound.
4. With the platform elevated, repeat step 2. When the
switch is properly
adjusted, the alarm will sound.
