this system. If the interlock system fails to
operate properly, shut off the engine and do not
operate the equipment until the system has been
repaired and is functioning properly.
Before using the equipment each day, check the
operation of the safety interlock system as
exp lained in you r TROY -BILT Chip per/Vac

THROTTLE CONTROL OPERATING INSTRUCTIONS
Your new engine throttle control
(see Fig. 4) has three positions in-
dicated on the control body:
FAST, SLOW, and STOP.
•When starting the engine, place
the lever at the FAST setting.
•Use the settings between FAST
and SLOW to regulate the engine
speeds. For heavy duty chipping
and shredding, you will want to
use the FAST setting. For light
duty chipping and shredding, or for
transporting your machine, you
may want to use aslower engine
speed. Doing so will result in re-
duced noise volume and gasoline
consumption.
•Move the lever all the way
back to STOP to shut offthe
engine. Remove any hearing pro-
tection and listen
to the sound of
the machine as it slows down.
There is an audible tone that
changes
as the cutting blades slow
down. Listen for all parts
to come
to acomplete stop.
IMPORTANT: Refer to Page 26
of your Manual for complete
"Starting and Stopping the
Engine" instructions. Your new
throttle control replaces the
On/Off Switch described on that
page.

THROTTLE CONTROL ADJUSTMENTS
The throttle control settings are
factory adjusted and unnecessary
adjustments should not be made.
However,
if the engine does not
start
or stop, or if it does not re-
spond to various throttle lever set-
tings' then the following adjust-
ments may be necessary.
DANGER
To prevent personal injury,
stop the engine, disconnect
the spark plug wire, and let
the engine and muffler cool
before inspecting or adjust-
ing the throttle control.
1. With the engine shut off and the
spark plug wire disconnected, put
the throttle control lever (on the
handlebar) in the FAST setting.
2.
If the throttle control is properly
adjusted, the Control Lever on the
engine (see Fig. 5) should touch
the High Speed Stop tab located on
the throttle control bracket.
If the
Control Lever does not touch the
High Speed Stop tab, proceed to
Step 3.
3. Loosen the Cable Clamp Screw
(Fig. 5) until the Throttle Cable is
free to move in the Cable Clamp
(do not remove the screw).
4. Push the Throttle Cable up until
the Control Lever touches the High
Speed Stop tab.
5. Hold the Control Lever at this
position and securely tighten the
Cable Clamp Screw.
6. Test the function
of the throttle
control by moving it back and
forth between the FAST and STOP
positions.
If properly adjusted, the
Control Lever should contact the
High Speed Stop tab and the Shut
Off Clip.
