P ROXIMITY S WITCH
Refer to Figure 2-5.
The Proximity Switch is a magnetically activated switch located near the rear of the chassis on the left
side. Its function is determined by the location of the lower elevating assembly tube.
P ROXIMITY S WITCH F 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 1,0 km/h
(0.62 mph).
When Completely Lowered:
• Power is supplied to the High Speed Circuit, allowing the machine to travel up to 3,7 km/h (2.3 mph).
