1.
Emergency Stop
: Press the red
EMERGENCY STOP button in, at any time,
under any conditions, and the entire machine
stops, and nothing moves. This switch must
be out (on) to start or run the MHP from the
platform control box. Pull the switch and it
will pop out (on). Press the switch in (off) if
the platform is to stay in one position for a
long time. That will turn the engine off and
and save fuel.
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.
Start
: 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 plat
form mov
ing
switches. Each is a three po si tion, mo men tary con -
tact, nor mally OFF switch.

boom to the left. RIGHT rotates the entire
turntable and boom to the right.

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.
