Towing
The aerial platform may be towed at slow speeds using
the optional tow kit. The tow vehicle must have sufficient
capacity to safely tow and stop itself and the aerial plat-
form on the steepest grade and type of surface that may
be encountered. Refer to Chapter 2 for the approximate
weight of the aerial platform.
Warning
The aerial platform is free to move when the drive
hubs are disabled. Death or serious injury can result.
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 and lay the
tow bar near the front of the chassis.
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
3′ (1 m) above the ground.
6. Shut the engine off and turn the battery disconnect
switch off.
7. Pull the steering float valve knob outward. The valve
is located on the right side of the turntable.
8. At each drive wheel, remove the two bolts from the
disconnect plate (refer to Figure 10.6). Turn the plate
over so the nipple points inward. Reinstall the two
bolts.

9. Do not exceed 10 mph (16 km/h) 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.
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.
10. After towing, push the steering float valve knob
inward.
11. At each drive wheel, remove the two bolts and return
the plate to its original position as shown in Figure
10.8.
12. Unfasten the tow vehicle from the machine and
replace the tow bar on the storage cradles.
13. Verify that the drive system operates properly.
