Snorkel AB46J - Manual (Page 30)

■ Ground Control Box
Controls for operating the AB46J from the
ground, are located on the right side of the
turntable.
The number of each control below corresponds
to the control’s call out on the control box
illustration.
1. Emergency Stop: Press the red button in, 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 out
for anything on the machine to work.
2. Platform/Ground Selector : Must be in the
GROUND position (down) for the ground
control box to work. The switch MUST be in
the PLATFORM position (up) for the platform
control box to work.
3. Master Key Switch: This is the master on/off
switch. Turn the switch to ON to begin work
with the AB46J.
4. 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.
5. Ground Operation: You must manually hold
this switch up any time you use one of the
seven platform moving switches, (switches 6
through 12), to move the platform. Holding
the switch up turns the hydraulic pump on in
preparation to do work.
Control switches 6 through 12 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.)
6. Riser Lift: UP raises the upper and lower
riser booms. DOWN lowers them.
7. Main Boom Lift: UP raises the base boom.
DOWN lowers the base boom.
8. Extend/Retract: EXTEND extends the inner
boom out of the base boom. RETRACT
retracts the inner boom into the base boom.
9. Jib: UP raises the jib boom. DOWN lowers
the jib boom.
10. Swing: CW (left) rotates the entire turntable
clockwise (as seen from above). CCW (right)
rotates the turntable counterclockwise.
11. Platform Level: UP rotates the platform up
relative to the end of the jib boom. DOWN
rotates the platform down.
12. 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.
13. Emergency Power: Continuously holding
this switch down activates a small, battery
powered hydraulic pump that supplies
emergency hydraulic 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.
