If the drive fault light is fl ashing or not lit, repeat
the previous steps to ensure the controls are set
up properly.
After repeating the previous steps, if needed, and
the drive fault light is still not a solid light remove
the aerial platform from service until qualifi ed main-
tenance personnel can make repairs.
5. Hold the appropriate toggle switch in the desired
direction.
6. Release the function toggle switch to stop move-
ment.
7. Release the ground operation switch to the center in
off position when no functions are being operated.
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 operate machine functions
using the upper controls (ref: Figure 4 on page 6).
1. At the lower controls, insert the key into the control
selector switch and turn the switch to the platform
position.
2. Place the emergency stop switch in the on posi-
tion.
3. Enter the platform and securely close the gate.
4. Attach the fall restraint lanyard to one of the anchor
points.
5. Pull the emergency stop outward.
6. Step down on the platform foot switch.
7. Visually check to make sure the drive fault light at the
lower controls is lit.
If the drive fault light is fl ashing or not lit, repeat
the previous steps to ensure the controls are set
up properly.
After repeating the previous steps, if needed, and
the drive fault light is still not a solid light remove
the aerial platform from service until qualifi ed main-
tenance personnel can make repairs.
Boom Operation
Use the following procedure to operate the turntable,
boom, or platform functions.
1. Step down on the platform foot switch. The platform
foot switch must be held down to operate the upper
controls.
2. Hold the appropriate control in the desired direction.
Always look in the direction of movement.

position or release the foot switch.
Driving and Steering
A
Danger
The aerial platform can tip over if it becomes unstable.
Death or serious injury will result from a tip-over ac-
cident. Do not drive an elevated aerial platform on
soft, uneven, or sloping surfaces. Do not drive the
machine on grades that exceed 25 percent.
For operation on grades up to 25 percent, it is recom-
mended that the main boom be near horizontal and the
jib be elevated just enough to provide adequate ground
clearance.
A 25 percent grade is a 0.76 m (30″) vertical rise in
3.05 m (10′) horizontal length.
Avoid driving with the platform over the front end of the
chassis. In this position the machine is difficult to control
because:
drive and steer control movements and their resulting
machine movements are reversed.
when driving fast, sudden turns or stops produce more
severe reactions to platform occupants.
more turning space is required to prevent the platform
from colliding with obstacles several feet beyond the
path of the tires.
A
Warning
Death or serious injury could result from improperly
driving or steering the aerial platform. Read and un-
derstand the information in this manual and on the
placards and decals on the machine before operating
the aerial platform on the job.
The blue and yellow arrows on the chassis indicate the
direction the chassis will move when the drive or steer
control is moved toward the corresponding color.
When the machine is in the stowed position, with the
booms centered between the rear wheels, the direction
of drive and steer control movement corresponds with
the direction of chassis movement.
When the turntable is rotated from the stowed position,
with the booms to either side of or in front of the chassis,
the direction of control movement does not correspond
with the direction of chassis movement.
To avoid confusion, always drive to the work area
or move between work areas with the turntable and
booms in the stowed position.
After arriving at the work area, the booms may be
positioned to the side or the front of the chassis for
fi nal positioning.
