X For example, the blue arrow on the chassis
points forward. To drive the machine forward,
move the joystick toward the corresponding
blue arrow. The drive speed is proportional
to the joystick position in two separate
ranges, low and high.
4. To stop drive motion, return the joystick to
neutral, release the foot switch, or press the
emergency stop.
❑ Steering
The steer control is located on the drive and steer
joystick. To turn to the left, move the joystick to the
left. To turn to the right, move the joystick to the right.
Reverse the steer control direction after
completing a turn to return to a straight line travel.
The steering wheels are not self-centering.
■ Electrical Power Outlet
The electrical box has 2, 3-prong, 230/115 volt AC
electrical connectors. Their combined output is
limited by a 15 amp circuit breaker.
When electrical power is required at the platform:
● plug a source of power into the power-input
connector at the rear of the chassis.
● place the Machine/Generator switch in the
Generator position if the machine is equipped
with an AC generator.
Unplug the source of power before moving the
aerial platform.
■ Air Line
The optional air line may be used to conduct air for
tool operation at the platform. The input connector
is at the lower rear of the turntable and the output
connector is at the platform. Maximum working
pressure of the line is 250 psi (1,723 kPa).
The air line may be used to conduct fluids such as
water or antifreeze solution. Contact your Snorkel
dealer for compatibility information before using
the air line to conduct other fluids.
Fluid in the air line can 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 at the turntable.
2. Open the output connector at the platform.
3. Raise the lower, main, and jib booms slightly
above horizontal.
4. Open the input connector at the turntable.
5. Allow the fluid to drain from the line.
6. Lower the booms and close both connections.
