1. Emergency Stop: Press the red
switch-cover down, at any time, under any
conditions, and the entire machine stops -
the engine turns off and nothing moves. This
switch must be up for anything on the
machine to work.

automobile ignition switch. Hold the key at
the start symbol (extreme clockwise position)
until the engine starts then release it to the
on position (bar symbol).Turn the key to off

for a long time. That will turn the engine off

only): This light will be lit while you choke the
engine (see CHOKE below).
3. Glow-Plug Indicator Light (diesel engines
only): This light will be on while the glow

light to go out before you try to start a diesel.
