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 inade-
quate clearance from, an energized conductor. Do not
go closer than the minimum safe approach distance
as defined by ANSI or national safety regulations.
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
accident. Operate the aerial platform on a firm, flat,
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
operate the aerial platform in unapproved locations
or wind conditions.
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 control valve, hydraulic, and bat-
tery trays.
3. Place the battery disconnect switch in the on position.
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. Twist the emergency stop button (refer to Figure 2).
2. Insert the key into the control selector/ground opera-
tion switch and turn the switch to the lower controls
position. Hold the switch in the lower controls position.
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 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.
Use the following procedure to operate the aerial platform
from the upper controls:
1. From the lower controls, twist the emergency stop
button to restore power (refer to Figure 2).
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.
3. Enter the platform and secure the gate.
4. From the upper controls, twist the emergency stop
button to restore power (refer to Figure 3).
5. The aerial platform may be driven and the platform
may be raised and lowered from the upper controls.
Platform
Use care when entering and exiting the platform to avoid
slipping and/or falling. Securely close the safety gate
when the platform is occupied.
Danger
The potential for an accident increases when the fold
down rails are lowered. Death or serious injury can
result in such accidents. Do not elevate the platform
with the fold down rails lowered. Use extreme care
when moving the aerial platform while the fold down
rails are lowered.
