A46JRT – 0261169

•  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).

Figure 8.2 – Upper Controls

  4.  Step down on the platform foot valve (refer to Figure 

8.3). This  valve must be held down to operate the 

upper controls.

Figure 8.3 – Platform

Figure 8.1 – Lower Controls

   2. Start the engine and let it warm to operating tem-

perature.

  3. Press and hold the ground operation button while 

operating the boom and turntable control buttons.

  4. Press and hold the appropriate function buttons to 

operate the machine.

  5.  Release the function button to stop movement.

Upper Controls

The upper controls may be used for driving the aerial 

platform and positioning the booms and platform while 

on the job.

Use the following procedure to set the machine up for 

operation at the upper controls.

  1.  At the lower controls, place the emergency stop button 

(refer to Figure 8.1) in the on position and place the 

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.
