A
Danger
Pinch points may exist between machine compo-
nents. Death or serious injury will result from be-
coming trapped between components. Do not attach
the tow bar to the tow vehicle until the counterweight
is to the side of the chassis.
2. Rotate the turntable, until the counterweight is to the
side of the chassis, to allow room to attach the tow
bar.
3. Attach the tow bar to the front steering arm with the
tow pin and snap pin.
4. Attach the tow bar to the tow vehicle.
5. Rotate the turntable so the counterweight is back at
the front of the chassis. Raise the platform about 1
m (3 ′) above the ground.
6. Shut the engine off and turn the battery disconnect
switch off.
7. At each drive wheel, remove the two bolts from the
disconnect plate (refer to Figure 10.7). Turn the plate
over so the nipple points inward. Reinstall the two
bolts.

8. Pull the steering float valve knob out. The knob is
located behind the rear door on the right side of the
turntable next to the fuel tank.
9. Do not exceed 16 km/h (10 mph) when towing. Use
caution when traveling around a curve or when turn-
ing a corner. If the tow bar contacts the chassis the
steering mechanism might be damaged or the tow
vehicle and the aerial platform could jackknife.
A
Warning
The aerial platform is free to move when the drive
hubs are disabled. Death or serious injury can re-
sult. Re-enable the drive hubs before operating the
aerial platform.

Towing
The aerial platform may be towed at slow speeds using
the optional tow kit. The tow vehicle must have suffi-
cient capacity to safely tow and stop itself and the aerial
platform on the steepest grade and type of surface that
may be encountered. Refer to Chapter 2 for the gross
vehicle weight of the aerial platform.
A
Warning
The aerial platform is free to move when the drive
hubs are disabled. Death or serious injury can re-
sult. Securely fasten the tow vehicle to the aerial
platform before disabling the drive hubs.
Use the following procedure to manually disengage the
drive hubs and tow the machine.
1. With the machine in the stowed position, remove
the tow bar from the storage cradles at the rear of
the chassis and lay the tow bar near the front of the
