Upper Controls
The upper controls may be used for driving the aerial platform and positioning the platform while on the job.
Before operating from the upper controls, properly set up the aerial platform as described under Preparing
for Operation. Use the following procedure to operate the aerial platform from the upper controls.
1.
From the lower controls, place the control selector switch in the upper position.
Note
The upper controls will not operate while the control selector is in the lower position.
2.
Enter the platform and lower the gravity gate.
3.
Turn and pull the emergency stop button out.
4.
The aerial platform may be driven and the platform may be raised and lowered from the upper
controls.
Driving
Danger
The aerial platform can tip over if it becomes un-stable. Death or serious injury will result from a
tip-over accident. Do not drive an elevated aerial plat-form on soft, uneven, or sloping surfaces. Do not
drive a fully stowed machine on grades that exceed 25 percent.
Warning
Death or serious injury can result from improperly driving or steering the aerial platform. Read and
understand the information in this manual and on the placards and decals on the machine before
operating the aerial platform on the job.
Use the following procedure to operate the drive functions.
1.
Place the drive/lift selector switch in the drive position.
2.
Squeeze and hold the interlock switch against the joystick.
•
To move forward, slowly push the joystick forward.
•
To move backward, slowly pull the joystick back-ward.
Drive Speeds
The drive speed is proportional to the joystick position. The farther the joystick is moved, the faster the
travel speed.
Drive speed ranges are interlocked through a limit switch that senses scissors arm position. When the
platform is elevated below approximately 1.8 m (6
′
), the aerial plat-form may be driven within the full
range of drive speeds. Above 1.8 m (6
′
) of elevation, only the slowest drive speed will work.
Danger
The potential for an accident increases when safety devices do not function properly. Death or serious
injury can result from such accidents. Do not alter, disable, or override any safety device.
