The throttle lever has three positions which allow the operator to adjust
the speed of the engine and thus the frequency of vibration in the
drums. Use the idle position (1), when starting or shutting down the
engine. Use the medium position (2), for approximately 55 Hz of
vibration. Use the high position (3), for approximately 66 Hz of
vibration.
Note: Always use the medium or high position when operating the
machine.

engine glow plugs, and the starter motor. The ignition key switch has
four positions: In the OFF (O) position no power is distributed by the
keyswitch; the ON position (1) allows power to the control panel
instruments; position (2) allows power to the glow plugs; and position
(3) allows power to the starter motor which cranks the engine.
