9. Push and release the brake release pump knob until
it can no longer be pumped.
10. Attach the winch line to the tie-down lugs (refer to
Figure 10.4) on the front of the chassis.

11. 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 seri-
ous injury could result. Close the free-wheeling valve
and reset the brakes before operating the aerial
platform.
12. Close the free-wheeling valve.
13. Drive the aerial platform forward or reverse and then
stop to reset the parking brakes. The brake release
valve can be heard when it resets, as the machine
is driven.
14. 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 acci-
dent. Do not drive on ramps that exceed the machine
gradeability specification, 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 machine gradeability specification.
A winch may also be used when poor traction, uneven
surfaces, or stepped ramp transitions make driving haz-
ardous.
Winching
Use a winch to load and unload the aerial platform on
ramps that exceed the machine gradeability specification.
A winch may also be used when poor traction, uneven
surfaces, or stepped ramp transition make driving haz-
ardous.
Use the following procedure to winch 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. 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
steering wheels are straight.
4. Properly stow the aerial platform.
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
platform.
5. Chock the wheels to prevent uncontrolled motion of
the aerial platform.
6. Unlatch and swing out the control valve tray on the
right side of the machine. The brake release valve,
pump, and free-wheeling valves are located on the
hydraulic manifold (refer to Figure 10.3).

7. Press inward on the brake release valve to the fully
open position.
8. Turn the free-wheeling valve counterclockwise to the
fully open position.
