UNCTION
A red LED at the rear of the switch should be ON when the elevating assembly tube is next to the switch
(the platform is lowered). The Proximity Switch controls the machine operation based upon the proximity
of the elevating assembly tube to the Proximity Switch.
When Elevating:
• The Level Sensor is enabled.
• The Depression Mechanism is enabled.
• Power to the High Speed Circuit is cut, preventing the machine from travel faster than 0,8 km/h

0.5 mph
).
When Completely Lowered:
• Power is supplied to the High Speed Circuit, allowing the machine to travel up to 3,2 km/h (
2.0 mph
)
when the Platform Controls Lift/Drive Switch is set to DRIVE HI.
