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) for anything on the MHP to work.
Pull the switch and it will pop out (on).
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.
NOTE: This switch also acts as the 'master
key switch'. Turning the key to the central
position and removing the key will effectively
disable all operations.
3. Choke/Cold Start: Hold the switch DOWN
while you start an engine that is at ambient
air temperature (a "cold" engine). This will
choke the engine.
4. Start Switch: Press and hold this switch
DOWN to operate the starter motor for the
MHP.
5. 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.
