Operation
S2646E/S3246E – 1370385 11
Operation
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 defined by ANSI or national safety regu-
lations.
Pinch points may exist between moving components.
Death or serious injury will result from becoming
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 unstable.
Death or serious injury will result from a tip-over ac-
cident. 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 per-
sonnel 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 unstable.
Death or serious injury will result from a tip-over ac-
cident. 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
Use the following procedure to prepare the aerial platform
for operation:
1. Perform a pre-operation safety and system function
inspection.
2. Close and latch the battery and hydraulic trays.
3. Place the battery disconnect switch in the on posi-
tion.
Lower Controls
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 testing
and inspection.
Use the following procedure to raise or lower the platform
using the lower controls.
1. Pull the emergency stop button outward (refer to
Figure 3).
2. Insert the key into the control selector switch and turn
the switch to the lower controls position.
3. Hold the ground operation switch upward. 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 may be used for driving and position-
ing the aerial platform while on the job.
Before operating the upper controls, properly set up the
aerial platform as described under Preparing for Opera-
tion.
Warning
The potential for an accident increases from improp-
erly driving or steering the aerial platform. Death
or serious injury could result from such accidents.
Make sure the upper control panel is at the front of
the platform, hooked on the guardrail, and hanging
inside the platform.
Avoid driving the platform with the upper controls facing
the rear or side of the machine. In this position the ma-
chine is difficult to control because the drive and steer
control movements and their resulting machine move-
ments will not correspond.
Only operate the upper controls when the panel is at
the front of the platform, hooked on the guardrail inside
the platform, and facing the front of the machine (refer
to Figure 4).
Use the following procedure to operate the aerial platform
from the upper controls:
1. From the lower controls, pull the emergency stop
button outward (refer to Figure 3).
2. Insert the key into the control selector switch and turn
the switch to the upper controls position.
Note
The upper controls will not operate while the control
selector is in the lower position.
