Snorkel MHP17 - Manual (Page 34)

■ Platform Control Box
Con trols for op er at ing the MHP16/47 from the plat -
form are lo cated on the plat form con trol box, with
the ex cep tion of the foot switch which is on the plat -
form 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 MHP16/47 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 and retract the booms. To
slew during emergency lower operate
emergency lower and slew switches
together.
Items 6 through 10 are the plat form mov ing
switches. Each is a three po si tion, mo men tary con -
tact, nor mally 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. Boom Raise/Lower: UP raises the boom.
DOWN lowers the boom.
8. Boom Extend/Retract: UP retracts the
boom. DOWN extends the boom.
9. Level Platform: UP raises the platform.
DOWN lowers the platform.
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.
