2. Turn the brake release/free-wheeling valve clock-
wise to the fully closed position. Push and release
the brake release pump knob several times, until it
becomes hard to push, to release the brakes.
3. Attach the winch line to the tie-down lugs on the front
of the chassis.
4. Remove the wheel chocks and use the winch to
position the aerial platform on the transport vehicle.
Warning
The aerial platform is free to move when the brakes
and free-wheeling valve are disabled. Death or serious
injury could result. Close the free-wheeling valve and
reset the brakes before operating the aerial platform.
5. Turn the brake release/free-wheeling valve fully
counterclockwise to the fully open position.
6. Drive the aerial platform forward or reverse and then
stop to reset the parking brakes.
7. Verify that the drive system and brakes operate
properly before operating the aerial platform.

Driving

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 drive on ramps that exceed 25 percent
grade, or where conditions of the ramp could cause
driving to be hazardous.
Use a winch to load and unload the aerial platform on
ramps that exceed the gradeability specification for the
machine. Refer to "Specifications" pages 22 to 27. A winch
may also be used when poor traction, uneven surfaces,
or stepped ramp transitions make driving hazardous.
Drive the aerial platform onto the transport vehicle if a
winch is not available and the ramp incline is within the
grade capability of the aerial platform.

Brake Release
Free-Wheeling Valve
Use the following procedure to drive the aerial platform
onto the transport vehicle.
1. Position the transport vehicle so the aerial platform
will not roll forward after it is loaded.
2. Chock the vehicle wheels so it cannot roll away from
the ramp while the aerial platform is loaded.
3. Remove any unnecessary tools, materials, or other
loose objects from the platform.
Caution
The extension deck is free to move when the exten-
sion handle locks are disengaged. Personal injury may
result from accidentally extending or retracting the
deck. Make certain both extension handle locks are
fully engaged when the deck is extended in the work-
ing position and when it is stowed. Do not attempt to
extend or retract the platform unless the aerial platform
is on a level surface.
4. Fully retract the platform extension deck and ensure
that it is secured in position, with the latch handle
locks fully engaged. Fully lower the platform.
5. Drive the aerial platform to the foot of the loading
ramp with the front wheels nearest the ramp. Make
sure the aerial platform is centered with the ramps
and that the steering wheels are straight.
6. Place the drive range switch in low (turtle) for climbing
or descending a ramp.
7. Drive the aerial platform on or off the transport vehicle
in a straight line through the grade transitions with
minimal turning.

Hoisting

Use a four point sling arrangement attached to the lifting
lugs when hoisting the aerial platform. Machine damage
can occur if the sling is attached anywhere else.
Warning
The potential for an accident increases when the aerial
platform is lifted using improper equipment and/or
lifting techniques. Death or serious injury could result
from such accidents. Use proper equipment and lifting
techniques when lifting the aerial platform.
Know the weight of the aerial platform and the capacity
of the lifting devices before hoisting.
• Lifting devices include the hoist or crane, chains,
straps, cables, hooks, sheaves, shackles, slings, and
other hardware used to support the machine.
• The empty vehicle weight is stamped on the serial num-
ber placard and is listed in the machine specifications.
