Warning
The potential for an accident increases when safety
devices do not function properly. Death or serious
injury can result from such accidents. Fully close
the emergency lowering knob before operating the
aerial platform.
2. Turn the knob to close the cylinder bleed down
valve.

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 at the rear of
the chassis 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 becom-
ing 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.

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

Warning
The aerial platform is free to move when the drive
hubs are disabled. Death or serious injury can result.
Re-enable the drive hubs before operating the aerial
platform.
