Snorkel AB46J - Manual (Page 32)

■ Platform Control Box
Controls for operating the AB46J from the
platform are located on the platform control box,
with the exception of the foot switch which is on
the platform floor.
The number of each control below
corresponds to the control’s call-out on the
control box illustration.
1. Emergency Stop: Press the large red button
down at any time, under any conditions, and
the entire machine stops — the drive motors
and pump turn off, the brakes automatically
set, and nothing moves. This switch must be
pulled to its up (or out) position if the AB46J
is to be controlled from the platform.
2. Boom Speed: This control determines how
fast the booms move. Set it to SLOW (turtle)
until you are very familiar with the way the
machine works or if the platform is working in
dangerous or cramped surroundings.
3. Drive Range: Switching from LOW to HIGH
changes the driving conditions from low
speed and high torque to the wheels to high
speed and low torque to the wheels. Set this
switch to LOW for driving on loading ramps
or other steep grades and when safety
considerations demand slow deliberate
machine movements. Set the switch to HIGH
to travel across hard surfaces when the
booms are down and retracted.
Items 4 through 10 are the platform moving
switches. Each is a three position, momentary
contact, normally OFF switch.
(See “Nomenclature and Serial Numbers” in
the “Specifications” chapter 3, for boom
identification.)
4. Jib: UP raises the jib boom. DOWN lowers
the jib boom.
5. Extend/Retract: EXTEND extends the inner
boom out of the base boom. RETRACT
retracts the inner boom into the base boom.
6. Main Boom Lift: UP raises the base boom.
DOWN lowers the base boom.
7. Riser Lift: UP raises the upper and lower
riser booms. DOWN lowers them.
8. Platform Level: UP rotates the platform up
relative to the end of the jib boom. DOWN
rotates the platform down.
9. Platform Rotate: CW (left) rotates the
platform clockwise (as seen from above)
relative to the end of the jib boom. CCW
(right) rotates the platform counterclockwise.
10. Swing: CW (left) rotates the entire turntable
clockwise (as seen from above). CCW (right)
rotates the turntable counterclockwise.
11. Emergency Power: Hold the switch toward
you and a small, battery powered hydraulic
pump comes on to supply power for the
machine. Boom movements will be slow and
have long lag times under EMERGENCY
POWER. DO NOT use this switch for normal
operation.
12. Horn: The horn is used to get the attention of
people on the ground.
13. Drive/Steer Controller: The Drive/Steer
Controller is a joystick type controller to
regulate the drive and steer movement as
follows:
● DRIVE FORWARD: Slowly push the
Drive/Steer controller FORWARD and the
AB46J moves forward. The further forward
you push the controller the faster the AB46J
goes (max. 3.0 mph, 4.8 km/hr).
● DRIVE REVERSE: Same as DRIVE
FORWARD except the AB46J chassis
moves backward
● STEER RIGHT: Slowly push the Drive/Steer
controller to the right and the front wheels
move in the direction for a right hand turn.
The longer you hold the controller to the right
the further the wheels turn.
● STEER LEFT: Works the same as STEER
RIGHT only for a left hand turn.
The wheels stay the direction you turn them,
they do not automatically return to center the
way automobile wheels do.
There are blue and yellow arrows on top of the
chassis. The blue arrows point to the
FORWARD end of the chassis and to the
LEFT side of the chassis. The yellow arrows
point to the REVERSE end of the chassis and
to the RIGHT side of the chassis.
The Drive/Steer controller is color coded to
match the arrows. The color coding is
designed to keep you from becoming
disoriented when you are aloft and the
platform is rotated with respect to the chassis.
