• Use low range (four wheel drive) for driving on
loading ramps or other steep grades and when
safety considerations demand slow deliberate
machine movement. Low range is for low speed,
high torque operation.
Boom Operation
Use the following procedure to operate the turntable,
boom, or platform functions.
1. Enter the platform and securely close the gate.
2. Attach the fall restraint lanyard to one of the anchor
points.
3. Pull the emergency stop outward (refer to Figure 8.2).

control selector handle in the upper control position.
2. Start the engine and let it warm to operating tem-
perature.
3. Determine the desired drive range for the specific
driving conditions. Place the drive range handle in
the appropriate position to achieve the desired drive
wheel operation.
• Use high range (two wheel drive) when traveling
across firm, flat, level surfaces. High range can
only be activated when the booms are stowed.
High range is for high speed, low torque operation.
