Chapter 9. Operation
The aerial platform may be operated from either the
lower or upper controls.
The aerial platform is not electrically insulated.
Death or serious injury can result from contact with,
or inadequate clearance from, an energized con-
ductor. Do not go closer than the minimum safe ap-
proach distance as defined by ANSI.
Pinch points may exist between moving compo-
nents. Death or serious injury can result from be-
coming trapped between components, buildings,
structures, or other obstacles. Make sure there is
sufficient clearance around the machine before
moving the chassis or platform. Allow sufficient
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 can result from a
tip-over accident. Operate the aerial platform on a
firm, flat, level surface. Avoid travel speeds and/or
rough terrain that could cause sudden changes in
platform position.
The platform rated work load is the total weight of the
personnel and equipment that may be lifted in the plat-
form. The work loads are stated on the platform rating
placard mounted on the toeboard at the front of the plat-
form.
The aerial platform can tip over if it becomes unsta-
ble. Death or serious injury can result from a
tip-over accident. Do not exceed the capacity val-
ues 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 particu-
lar conditions encountered.
Preparing for Operation
Make certain the batteries are charged and the charger
is unplugged before operating the aerial platform. Use
the following procedure to prepare the aerial platform
for operation.
1. Perform a prestart inspection as described in
Chapter 8.
2. Close and latch the battery and hydraulic compo-
nent trays.
3. Place the battery disconnect switch in the on posi-
tion.
Lower Controls
The lower controls override the upper controls. This
means that the lower controls may be used to operate
the platform regardless of the position of the upper con-
trols emergency stop button.
Only the platform raise and lower functions may be op-
erated from the lower controls. The lower controls may
be used for initial set up of the aerial platform and for
positioning the platform while testing or inspection.
Use the following procedure to raise or lower the plat-
form using the lower controls.
1. Pull the emergency stop button outward (refer to
Figure 9.1).
Figure 9.1—Lower Controls
2. Place the control selector switch in the lower posi-
tion.
3. Hold the platform raise/lower toggle switch up to
raise the platform and down to lower it.
4. Release the toggle switch to stop movement.
Upper Controls
The upper controls (refer to Figure 9.2) may be used for
driving the aerial platform and positioning the platform
while on the job.
