Snorkel Guard

When the Snorkel Guard system is activated, use the
following procedure.
Warning
The potential for an accident increases when safety
devices do not function properly. Death or serious
injury could result from such accidents. Do not alter,
disable, or override any safety device.
1. When machine is stopped due to activation of the
Snorkel Guard system, immediately depress the
emergency stop, release the foot valve and all con-
trols. Perform an assessment of the situation which
caused the system to activate.
2. If it is determined that all controls are released and
operation can proceed, return the emergency stop
to the on position, and release the Snorkel Guard rail
above the upper controls.
3. Activate the foot valve.
4. Activate the necessary functions to move the platform
away from the obstacle that caused the Snorkel
Guard activation.
5. Assess the machine for any damage. If damage
occurred, return to the stowed position, exit the unit
and perform a thorough inspection before returning
to service.

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 gross vehicle
weight of the aerial platform.
Danger
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 cradle and lay it near the
front of the chassis.
Danger
Pinch points may exist between machine compo-
nents. Death or serious injury can result from becom-
ing trapped between components. Do not attach the

tow bar to the tow vehicle until the booms are to the
side of the chassis.
2. Rotate the turntable, until the booms are to the side
of the chassis, to allow room to attach the tow bar.
3. Attach the tow bar to the bushing on the steering arm
with the hitch pin. Install the keeper on the pin.
4. Position the tow vehicle in front of the aerial platform.
Set the brakes on the tow vehicle.
5. Attach the ring end of the tow bar to the tow vehicle.
6. Rotate the turntable so the booms are back at the
front of the chassis in the stowed position. It may be
necessary to raise the booms slightly to keep the
platform from scraping the ground if the machine will
be towed on a slope.
7. Shut the engine off and turn the battery disconnect
switch off.
8. At each drive wheel, remove the two bolts from the
disconnect plate (refer to Figure 10.1). Turn the plate
over so the nipple points inward. Reinstall the two bolts.

9. Pull the steering float valve knob out. The steering
float valve is at the front of the chassis beside the
steering arm.
10. Do not exceed 10 miles per hour (16 km/h) when
towing. Use caution when traveling around a curve
or when turning 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.
Danger
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.
