Drive Speeds
The drive speed is proportional to the joystick position.
The farther the joystick is moved, the faster the travel
speed.
Always slow down and shift the drive system to low
range before traveling over rough terrain or any sloped
surface.
Drive speed ranges are interlocked through limit switches
that sense the main and tip boom position.
•
When either boom is elevated or extended, only the
slowest drive speed will work regardless of the drive
range switch position.
•
To avoid a sudden speed change from high to low el-
evated boom speed, always bring the machine to a stop
before raising the booms from the stowed position.
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.
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
All Motion Alarm
The optional all motion alarm sounds loud intermittent
beeps anytime the machine functions are being oper-
ated.
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 power-
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 14 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 genera-
tor position.
Air Line
The optional air line may be used to conduct air for tool
operation at the platform.
•
The input connector is at the rear of the chassis and
the output connector is at the platform on the rotator
guard.
•
The maximum working pressure of the line is
1,723 kPa (250 psi).
The air line may be used to conduct fluids such as water
or antifreeze. Contact Snorkel for compatibility information
before using the air line to conduct other fluids.
Caution
Fluid in the air line may damage some air tools or
freeze and damage the line. Drain and blow out the
air line after using it to conduct fluids.
Use the following procedure to drain the air line.
1. Close the input connector on the chassis.
2. Open the output connector at the platform.
3. Raise the booms slightly above horizontal.
4. Open the input connector on the chassis.
5. Allow the fluid to drain from the line.
6. Lower the boom and close both connections.
