1. Position the transport vehicle so the aerial platform
will not roll forward after it is loaded.
2. Remove any unnecessary tools, materials, or other
loose objects from the platform.
3. Drive the machine to the foot of the loading ramp with
the front wheels nearest the ramp. Make sure the
machine is centered with the ramps and that the steer-
ing wheels are straight.
4. Properly stow the aerial platform.
A
Warning
The aerial platform is free to move when the brakes
are released. Death or serious injury can result. Re-
enable the brakes before operating the aerial plat-
form.
5. Chock the wheels to prevent uncontrolled motion of
the aerial platform.
6. Use a 7 /
8
″
wrench to rotate each brake release cam
90° (refer to Figure 10.3). Rotate the cam on the right
brake cylinder counterclockwise and the one on the
left brake cylinder clockwise. This will retract the brake
pins from the wheel lugs releasing the brakes. Re-
move the wrench.

7. Unlatch and swing out the hydraulic tray on the right
side of the chassis. The free-wheeling valve is located
on the hydraulic manifold (refer to Figure 10.4). Turn
the free-wheeling valve counterclockwise to the fully
open position.

8. Attach the winch line to the tie-down lugs (refer to
Figure 10.5) on the front of the chassis.

9. Remove the wheel chocks and use the winch to po-
sition the aerial platform on the transport vehicle.
10. Close the free-wheeling valve.
11. Use a wrench to manually reset the parking brakes.
12. After unloading the aerial platform from the transport
vehicle, verify that the drive system and brakes oper-
ate properly before operating the aerial platform.
Driving
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 drive on ramps that exceed
20 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 a 20 percent grade. A20 percent grade
is a 24
″
(0.61 m) vertical rise in 10
′
