IMPORTANT
Experience indicates that alcohol
blended fuels (called gasohol or using
ethanol or methanol) can attract moisture which leads to separation and
formation of acids during storage.
Acidic gas can damage the fuel system of an engine while in storage.
To avoid engine problems, empty the
fuel system before storage for 30 days
or longer. Drain the gas tank, start the
engine and let it run until the fue! lines
and carburetor are empty. Use fresh
fue! next season.
Never use engine or carburetor cleaner products in the fuel tank or perma*
nent damage may occur.
See the STORAGE section for additional information.

STARTING
YOUR ENGINE
(For location of controls, refer to
"KNOW YOUR UNIT.")
STOPPING YOUR ENGINE:
TO stop a running engine, move the
switch to the OFF position.
ON/OFF Switch

• Pull starter rope sharply 5 times.
NOTE: The engine may sound as if it
is trying to start before the 5 th pull. if
so, go to the next step immediately.
• Move choke lever to "Half Choke."
• Pull the starter rope sharply until engine runs, but no more than 6 pulls.
NOTE: If the engine has not started
after 6 pulls (at half choke), check to
make sure the switch and the choke
lever are in the proper positions. Then,
move the choke lever to the "Full
Choke" position and press the primer
bulb 6 times; pull the starter rope 2
more times. Move the choke lever to
"Half Choke" and pul! the starter rope
until the engine runs, but no more than
6 more pulis.
NOTE: If engine still has not started, it
is probably flooded. Proceed to "Starting a Flooded Engine."
• Allow the engine to run 10 seconds,
then move the choke lever to "Off
Choke." Allow the unit to run for 30
more seconds at "Off Choke," then
release the throttle trigger.
NOTE: If engine dies with choke lever
at the "Off Choke" position, move the
choke lever to "Half Choke" and pu!l
the rope until the engine runs.
STARTING A WARM ENGINE THAT
HAS NOT RUN OUT OF FUEL:
• Make sure switch is in ON position.
• Move choke lever to "Half Choke."
° Squeeze and hold the throttle trigger.
Keep throttle trigger fully squeezed
until the engine runs smoothly.
• Pull starter rope sharply until the engine runs, but no more than 5 pulls.
• Allow engine to run 10 seconds, then
move the choke lever to "Off Choke."
Release the throttle trigger.
NOTE: If engine has not started, pull
starter rope 5 more pulls. If engine still
does not run, it is probably flooded.
Proceed to "Starting a Flooded Engine."

BEFORE STARTING THE ENGINE:
• Fue!the engine.Then move 10 feet
(3 meters)away from the fueling site.
DANGER: The cutting blade will turn
when the engine starts.
WARNING: Avoid anycontactwith
the muffler.A hot muffler can causeseriousburns.

before cleaning.
SETTING THE EDGING DEPTH
WARNING: Never attempt to adjust
the depth adjusting wheel when the
engine is running. Always release the
throttle trigger, wait until the blade
stops turning, move the On/Off switch
to the OFF position, and disconnect
spark plug before making adjustments.
"Youredger is equipped with two
edging depths:
• Half depth for shallow edging (1").

Flooded engines can be started by
placing the switch in the ON position
and the choke lever in the "Off Choke"
position; then, pull the rope to clear the
engine of excess fuel. This could require pulling the starter rope many
times depending on how badly the unit
is flooded.
If unit still doesn't start, call the 1-800
number listed on the front of this
manual.

WARNING:
Serious injury to the operator and others can occur if the carburetor is not property adjusted. Keep
others away when making carburetor
adjustments. The blade shaft wil! be
spinning during most of this proc_'.__
Wear your protective equipment _:
observe all safety instructions.
Remove blade before making carburetor adjustments. Do not make adjustments from the blade side of the unit.
Hold the unit with your hand.
Recheck idle speed after each adjustment. The blade shaft must not turn at
idle speed to avoid serious injury to the
operator or others.
• Poor engine performance can be resuit of other causes such as dirty air
filter, carbon build-up on muffler outlets, etc. See "Troubleshooting
Chart" before proceeding with carburetor adjustments.
• For best results, it is recommended
that you have your Sears Service
Center make all carburetor adjustments. Your dealer has the training,
experience, and tools necessary to
properly adjust your unit to meet our
factory performance specifications.
This service is not covered by warranty. If it becomes necessary for
you to make carburetor adjustments
yourself, follow the described procedures very carefully.
• Very small adjustments can affect
engine performance, it is important
to turn the screw a very small
amount per adjustment and test performance before making further adjustments. Each adjustment should
be no more than the width of the slot
in the adjusting screw.
• This is a complicated task. Follow
instructions in sequence as indicated.
TROUBLESHOOTING
SUGGESTIONS
° Engine will not continue to run at idle
position. See "Idle Speed Adjustment" and "Low Speed Mixture Adjustment."

• Blade continues to spin when engine

• Loss of cutting power which cannot
be corrected by cleaning the air filter.
See "High Speed Mixture Adjustment."
• Engine will not run. See
"Troubleshooting Chart." Then, if the
carburetor requires adjustment, begin with "Basic carburetor Settings."
BASIC CARBURETOR SETrlNGS

• if performanceissatisfactory,proceed
to "Low Speed Mixture Adjustment."
• If the engine does not accelerate
smoothly, turn the low speed mixture
screw counterclockwise a small
amount (no more than the width of
the slot in the adjusting screw). Repeat step until smooth acceleration
is obtained. Do not attempt to turn
the screws beyond the stops as
damage can occur.
NOTE: It may be necessary to repeat
"Idle Speed Adjustment" through "Acceleration Check" to obtain correct adjustments.
LOW SPEED MIXTURE
ADJUSTMENT
• Allow engine to idle.
• Turn the low speed mixture screw
slowly clockwise until the speed
starts to drop. Do not attempt to turn
the screws beyond the stops as
damage can occur.

Prepare unit for storage at the end of
the season or if it wilt not be used for
30 days or more.
WARNING:

• Turn low speed mixture screw counterclockwise until the speed increases and then starts to drop
again. Do not attempt to turn the
screws beyond the stops as damage
can occur.
= Set low speed mixture screw at the
midpoint between the two positions.
• Readjust idle speed (see Idle Speed
Adjustment).
HIGH SPEED MIXTURE
ADJUSTMENT
CAUTION: Do not operate engine at
full throttle for prolonged periods while
making high speed adjustments as
damage to the engine can occur.
• Support the unit so the blade will not
make contact with any object, Do not
make adjustments from the blade
side of the unit.
° Allow the engine to idle, then
