CONTROLS

DESCRIPTION OF CONTROLS
You will use these controls every time you operate your diaphragm
pump.
Throttle Lever
The throttle lever controls the
engine speed. Moving the throttle
lever fully to the left gives
maximum engine speed. Moving
the throttle lever fully to the right
returns the engine to idle speed.
The pump output can be controlled by adjusting the throttle lever to the
desired position. At maximum throttle position, the pump will deliver
the highest output volume. Moving the throttle toward the idle position
will decrease the output volume of the pump.
Choke Lever
The choke is used to provide an
enriched mixture when starting a
cold engine. Move the choke to
the CLOSED position when
starting a cold engine. If the
engine is warm, leave the choke
in the OPEN position.
Fuel Valve Lever
The fuel valve lever is used to
stop flow of fuel from the fuel
tank to the carburetor. The fuel
valve lever must be in the ON
position to start and operate the
engine. Turn the fuel valve lever
to the OFF position when the
pump is not in use.
