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 plat-
form regardless of the position of the upper controls emer-
gency stop button.
Only the platform raise and lower functions may be oper-
ated from the lower controls. The lower controls may be
used for initial set up of the aerial platform and for posi-
tioning the platform while testing or during inspection.
Use the following procedure to raise or lower the platform
using the lower controls.
1. Pull the emergency stop button outward (refer to Fig-
ure 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.
Lowering Interrupt
When the platform is lowered to about 1.5 m (5 ′) lowering
stops. The platform will not lower for five seconds regard-
less of the platform raise/lower switch position.
Center the switch in neutral to reset the lowering func-
tion, then continue to lower the platform.
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.
Before operating from the upper controls, properly set up
the aerial platform as described under Preparing for Op-
Chapter 9 – Operation
The aerial platform may be operated from either the lower
or upper controls.
A
Danger
The aerial platform is not electrically insulated.
Death or serious injury will 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 or national
safety regulations.
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
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 un-
stable. Death or serious injury will 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. 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
raise the platform in wind speeds above 12.5 m/s
(28 mph).
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 at the rear of the platform.
A
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
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 (refer to Chapter 8).
2. Close and latch the battery and hydraulic trays.
