Engine Throttle Lever
The throttle lever on the right
handlebar (G, Figure 3-3) is used
to adjust the
engine speed
as well as
start and stop
the engine (a
„ secondary
Figure 3-3 throttle lever
is located on the front of the 8HP
and lOHP engines—see M, Fig. 3-5.)
Move the lever away from the
STOP position before starting the
engine. Engine speeds can be var­
ied between the FAST and SLOW
settings. Use the STOP position to
turn the engine off.
Engine Choke Control
The choke control lever (H,
Figures 3-4 or 3-5) makes starting
a cold engine easier. The choke in­
creases or decreases the amount of
air in the carburetor’s fuel-air mix­
ture. Use the CHOKE position
when starting a cold engine. After
starting, gradually return the lever
to the RUN position.
Engine Recoil Starter
The recoil starter (I, Eigures 3-4
or 3-5) is used to manually start
the engine. Before pulling the
starter rope, the Wheels/Tines/PTO
Drive Lever must be in NEUTRAL
and your free hand must be on top
of the fuel tank to stabilize the
tiller.
Keyswitch Starter
The keyswitch starter on electric
start models (J, Eigure 3-6) has
three posi­
tions: OEE,
RUN and
START. Turn
the key to
START to
start the en­
gine. Release
the key and it
will return to the RUN position.
Turn the key to OFF to stop the en­
gine. (A second way to stop the
engine is to move the engine throt­
tle lever to the STOP position.)
Figure 3-6
Fuel Shut-Off Valve
The shut-off valve (K, Fig. 3-7)
is located under the fuel tank. The
valve must be in the ON position
(1/4 turn counterclockwise) to
operate the engine. Close the shut­
off valve when the tiller is trans­
ported or not in operation to pre­
vent fuel leakage.
On/Off Switch
The 8 HP and lOHP Briggs &
Stratton engines have an On/Off
Switch (L, Figure 3-5) which must
be switched to ON before operat­
ing the engine.
