The aerial platform may be operated from either the
lower or upper controls.
Danger
The aerial platform is not electrically insulated. Death
or serious injury will result from contact with, or in-
adequate clearance from, an energized conductor.
Do not go closer than the minimum safe approach
distance as defi ned by ANSI or national safety reg-
ulations.
Pinch points may exist between moving compo-
nents. Death or serious injury will result from be-
coming trapped between components, buildings,
structures, or other obstacles. Make sure there is
suffi cient clearance around the machine before
moving the chassis or platform. Allow suffi cient
room and time to stop movement to avoid contact
with structures or other hazards.
The aerial platform can tip over if it becomes unsta-
ble. Death or serious injury will result from a tip-over
accident. Operate the aerial platform on a fi rm, fl at,
level surface. Avoid travel speeds and/or rough ter-
rain that could cause sudden changes in platform
position. Do not drive or position the aerial platform
for elevated use near any drop-off , hole, slope, soft
or uneven ground, or other tip-over hazard. Do not
operated the aerial platform in unapproved loca-
tions or wind conditions. Do not raise the platform
in wind speeds above 28 mph (12.5 m/s).
The platform rated work load is the total weight of the
personnel and equipment that may be lifted in the
platform.
The work loads are stated on the platform rating placard
at the entrance to the platform.
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 exceed the capacity values
indicated on the platform rating placard.
Capacity values indicate the rated lifting capacity and
do not indicate aerial platform stability.
The operator bears ultimate responsibility for ensuring
that the aerial platform is properly set up for the particular
conditions encountered.

Preparing for Operation

form for operation:
1. Perform a prestart inspection (refer to Chapter 7).
2. Place the battery disconnect switch in the on posi-

3. Hold down the choke/glowplug switch for approx-
imately three (3) seconds. Release the choke/
glowplug switch and hold down the start switch until
the engine starts.
4. Hold the ground operation switch and hold the
platform raise/lower toggle switch up to raise the
platform and down to lower it.
5. Release either switch to stop movement.

Upper Controls

The upper controls may be used for driving and posi-
tioning the aerial platform while on the job.
Before operating the upper controls, properly set up
the aerial platform as described under Preparing for
Operation.
Use the following procedure to operate the aerial plat-
form from the upper controls:
1. From the lower controls, pull the emergency stop
button outward (refer to Figure 8.1).
2. Insert the key into the control selector switch and
