Snorkel MHP34J(Bi-Energy Option) - Manual (Page 34)

■ Platform Control Box
Controls for operating the MHP12/34J from the
platform are located on the platform control box,
with the exception of the foot switch which is on the
platform floor.
NOTE
The number of each control below corresponds to
the control’s call out on the control box illustration.
1. Emergency Stop: Press the EMERGENCY
STOP switch cover down, at any time, under
any conditions, and the entire machine stops,
and nothing moves. This emergency stop
switch cover must be up and the switch
turned on for anything on the MHP12/34J to
work.
2. Choke/Cold Start: Hold the switch UP while
you start an engine that is at ambient air
temperature (a "cold" engine). This will choke
the engine.
3. Anti-Restart: This switch works like an
automobile ignition switch. Hold it at START
until the engine starts, then release it to ON
(-). If the engine dies in ON, the key must be
turned to OFF (O) before it will go back to
START. Turn the switch to OFF if the platform
is to stay in one position for a long time, that
will turn the engine off and save fuel.
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. Emergency Lower: If the engine stops and
cannot be restarted, hold the switch down
and this will lower the upper and lower
booms (not the jib boom). To slew during
emergency lower operate emergency lower
and slew switches together.
Items 6 through 10 are the platform moving
switches. Each is a three position, momentary con-
tact, normally OFF switch.
NOTE
(See “Nomenclature and Serial Numbers” in the
“Specifications” chapter 3, for boom
identification.)
6. Platform Rotate: (Option) LEFT rotates the
platform left. RIGHT rotates the platform
right.
7. Lower Boom: UP raises the lower boom.
DOWN lowers the lower boom.
8. Upper Boom: UP raises the upper boom.
DOWN lowers the upper boom.
9. Jib Boom: UP raises the jib boom. DOWN
lowers the jib boom.
10. Slew: LEFT rotates the entire turntable and
boom to the left. RIGHT rotates the entire
turntable and boom to the right.
11 Lift Enable: The platform can only be raised
when this light is lit. When this light is not lit
the platform will not raise because the
outriggers are not properly set.
12. Foot Switch: You must step down on the foot
switch, and hold it down when you use any
platform control that causes the platform to
move.
