OIL RECOMMENDATIONS
Only use high quality detergent oil rated
with API service classification SG. Select
the oil's SAE viscosity grade according to
your expected operating temperature:

<<__Colder
_W30(<*--__

3--_2°F-_A'LL'35>>
Warmer

>>I

NOTE: Although multi-viscosity oils (5W30,
10W30, etc.) improve starting in cold
we_tther, these multi-viscosity oils will result
in increased oil consumption when used
above 32°F. Check your engine oil level
more frequently to avoid possible engine
damage from running low on oil.

TO ADD ENGINE OIL
• Place the Edger on a level surface.
• Remove the oil fill cap/dipstick as shown
in next figure.
• Fill the engine crankcase, pouring slowly.
DO NOT OVERFILL.
For approximate
capacity see PRODUCT SPECIFICATIONS on page 11 of this manual.
• Reinstall the oil fill cap/dipstick and
tighten securely. Wipe away excess oil.
• Check oil before each use. Add if
needed.

CAUTION: Never fill the gas tank
while the engine is running or hot.
Immediately wipe off any spilled gasoline
before attempting to start the engine.

FILL GAS:
NOTE: ENGINES WHICH ARE CERTIFIED TO COMPLY WITH CALIFORNIA
AND US EPA EMISSION REGULATIONS
FOR ULGE ENGINES: Are certified to
operate on regular unleaded gasoline.
Include the following emission control
system(s): EM, TWC (if so equipped).
include any user adjustable features therefore no other adjustments are needed.
Fill the fuel tank with clean, fresh, unleaded
premium, or reformulated automotive
gasoline only. DO NOT use leaded
gasoline.
Be sure that the container you
pour the gasoline from is clean and free
from dust or other foreign particles. Never
use gasoline that may be stale from long
periods of storage in the container.
Reinstall fuel cap.
WARNING: Experience indicates that
alcohol blended fuels (called gasohol or
using 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, the fuel system
should be emptied before storage of 30
days or longer. Drain fuel tank, start engine
and let it run until fuel lines and carburetor
are empty. Use fresh fuel next season. See
Storage Instructions for additional information. Never use engine or carburetor cleaner
products in the fuel tank or permanent
damage may occur.
Z_ WARNING:
Gasoline is flammable
and caution must be used when handling or
stodng it. Do not fill fuel tank while Edger is
running, hot, or when Edger is in an
enclosed area. Keep away from open
flame, electrical spark, and do not smoke
while filling the fuel tank. Never fill fuel tank
completely; but fill the tank to within 1/4-1/2
inch from the top to provide space for
expansion of fuel. Always fill fuel tank
outdoors and use a funnel or spout to
prevent spilling. Make sure to wipe up any
spilled fuel before starting the engine. Store
gasoline in a clean, approved container,
and keep the cap in place on the container.
Keep gasoline in a cool, well ventilated
place; never in the house. Never buy more
than a 30 day supply of gasoline to ensure
volatility. Gasoline is intended to be used as
a fuel for internal combustion engines;
therefore, do not use gasoline for any other
purpose. Since many children like the smell
of gasoline, keep it out of their reach
because the fumes are dangerous to
inhale, as well as being explosive.
TO START

Z_ WARNING:
Never run the engine
indoors or in a poorly ventilated area.
Engine exhaust contains carbon monoxide,
an odorless and deadly gas. Keep hands,
feet, hair and loose clothing away from any
moving parts on the engine or Edger. Avoid
the muffler and surrounding areas. Temperaturas may exceed 150 ° F.

holding the starter handle.
NOTE: If engine fails to start after three
pulls, push primer button two times and
pull starter rope again.

EDGING TIPS
• Edging is best performed when conditions
are dry. If the soil is too wet, dirt becomes
packed in and around the blade causing
premature belt wear and decreased
performance.

• When the engine starts, run at full engine
speed during normal use.
NOTE: The cutting blade speed is
controlled by the engine speed. To
reduce the cutting blade speed, push
back on the throttle control lever. To

spark or pilot light from a furnace, water
heater, clothes dryer, cigarette, etc.

EDGER
• Clean the Edger thoroughly; remove all
debris and wipe the unit dry.
• Inspect the Edger for worn or damaged
parts and tighten all loose hardware.
• Oil all points described in the Lubrication
paragraph in the MAINTENANCE
section
of this manual.
• Store the Edger in a protected area and
cover for additional protection.

• Store the Edger in the wheels-down,
operating position. If the Edger is stored
in any other position, oil from the
crankcase could enter the cylinder,
causing a service problem.
You can keep your engine in good operating condition during storage by:
• Changing oil.
• Lubricating the piston/cylinder area. This
can be done by first removing the spark
plug and squirting clean engine oil into
the spark plug hole. Then cover the spark
plug hole with a rag to absorb oil spray.
Next, rotate the engine by pulling the
starter two or three times. Finally,
reinstall spark plug and attach spark plug
wire.

IMPORTANT:A
yearly checkup or tuneup by a Craftsman Service Center is a
good way of ensuring that your Edger
will provide maximum performance for
the next season.

ENGINE
IMPORTANT:
It is important to prevent
gum deposits from forming in essential
fuel system parts such as the carburetor,
fuel filter, fuel hose, or tank during storage.
Also, experience indicates that using
alcohol-blended fuels (called gasohol,
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 prevent engine damage (if Edger is not
used for more than 30 days) follow the
steps below.
• To remove gasoline, run the engine
until the tank is empty and the engine
stops.
• If you do not want to remove gasoline,
a fuel stabilizer (such as Craftsman fuel
stabilizer No. 33500) may be added to
any gasoline left in the tank to minimize
gum deposits and acids. If the tank is
almost empty, mix stabilizer with fresh
gasoline in a separate container and add
some to the tank. Always follow instructions on stabilizer container, Then run
engine at least 10 minutes after stabilizer
is added to allow mixture to reach
