Pivoting Front Axle; Snorkel Guard Overide Swirtch; Tilt Alarm; All Motion Alarm - Snorkel A62JRT Operator's Manual

Operation
Do not use the aerial platform if it drives in high or mid
speed when the main boom is above horizontal or the
tip boom is extended.

Pivoting Front Axle

The front axle pivots to maximise tire contact with the
ground. This helps to optimize both traction and machine
stability.
The axle has the ability to pivot when either the ground
operation switch is engaged at the lower controls, or when
the foot switch at the upper control station is engaged.
While driving between work sites, the pivoting axle:
• Improves traction
• Reduces ground pressure
Snorkel Guard Override Switch
When the Snorkel Guard system is activated, the Snorkel
Guard override switch (refer to Figure 4 on page 7) is used
to override the system to operate main boom down, riser
boom down, or jib down functions. The switch is spring
returned to the normal operation position.
Warning
The potential for an accident increases when safety
devices do not function properly. Death or serious
injury could result from such accidents. The Snorkel
Guard override switch must only be used when all
controls are released and in the neutral position. If
a zero or neutral state cannot be achieved, depress
the emergency stop and obtain assistance at the
lower controls.
1. When machine is stopped due to activation of the
Snorkel Guard system, immediately depress the
emergency stop, release the foot switch and all con-
rtrols. 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 activate the Snorkel Guard
override switch.
3. Activate the foot switch.
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.

Tilt Alarm

If the aerial platform chassis is out of level more than 3.5
degrees when the main boom is raised or extended, or
when the riser boom is raised, an alarm will sound. The
tilt alarm is located under the upper control panel.
Danger
The aerial platform can tip over if it becomes unsta-
ble. Death or serious injury will result from a tip-over
accident. Do not drive or position the aerial platform
for elevated use near any drop-off, hole, slope, soft
or uneven ground, or other tip-over hazard.
Completely lower the booms and then drive to a level
surface when the tilt alarm sounds.
The tilt alarm is for added protection and does not justify
operating on anything other than firm, flat, level surfaces.

All Motion Alarm

The optional all motion alarm sounds loud intermittent
beeps anytime the machine functions are being operated.

Electrical Power Outlet

Power may be supplied to the outlet using an external
power source or by operating the optional AC generator.
To use the outlet, plug a source of power into the pow-
er-input connector on the right side of the chassis. Unplug
the source of power before moving the aerial platform.

AC Generator

The optional generator supplies power to the electrical
outlet only when the engine is running and the machine
is stationary. The machine functions will not operate when
the generator switch is in the generator position.
Caution
Cold hydraulic oil does not flow well and may produce
improper generator output voltage. Improper outlet
voltage can damage some electrical power tools and
equipment. Warm the hydraulic oil before operating
the generator.
Do not operate the generator unless the hydraulic oil is
at operating temperature. Refer to "Cold Weather Start-
Up" on page 15 for a hydraulic oil warm-up procedure.
To supply power to the electrical power outlet, start the
engine and place the generator switch in the generator
position.
The engine will run at high idle while the generator is
operating. The generator will continue to operate as
long as the engine is running and the switch is in the
generator position.

Air Line

The optional air line may be used to conduct air for tool
operation at the platform.
