STARTING CONTROLS

See Figures 1 & 2 for the following instructions.

Units with Optional Electric Start

A. Electric Start Button - The electric start button

(A) activates an electric starter mounted to the
engine, eliminating the need to pull the starter han-
dle. The electric start button operates on 120 Volts
AC, which is provided by connection to the extension
cord provided with units equipped with this feature.
Connect this extension cord ONLY to a properly
grounded 3 prong electrical outlet.

Manual Start

B. Fuel Valve - The fuel valve (B) is located under the

fuel tank. It is used to turn the fuel supply off for out-
of-season storage.

C. Starter Handle - The starter handle (C) connects to a

starter cord to manually start the engine. Pulling
starter handle rapidly spins the engine crankshaft,
cycles the engine, and generates the spark neces-
sary for starting the engine.

D. Primer Button - When pressed, the primer button

(D) provides initial fuel to help start a cold engine.
Normally, pressing the primer button twice will pro-
vide enough fuel to start a cold engine.

E. Throttle Lever - The throttle lever (E) controls the

engine speed. For best overall performance, the
throttle lever should be set to the FAST position. Use
the SLOW position only for warming the engine, or to
help prevent snow/ice freeze-up when shutting the
unit down for the day.

F. Engine Key - The engine key (F) prevents the

engine from being started by unauthorized individu-
als. The key must be fully inserted into the key slot
for the unit to start. The key is also used to stop the
engine by pulling the key out of the key slot.

G. Choke Knob - The choke knob (G) adjusts the

air/fuel mixture, and is used to help start a cold
engine by providing a richer mixture. Once the engine
is warm and running smoothly, the choke knob
should be set to the off position to provide a normal
air/fuel mix.
