REMEMBER
Keep semiautomatic line head
3 inches above
the ground while trimming
Figure 9
• SCALPING The scalping technique removes unwanted vegetation Allow the tip of the line to strike the ground around trees, posts, monuments etc This technique increases line wea_
__ // SCALPING
1:
• For trimming or scalping, use partial throttle to increase line life especially:
- dudng light duty cutting
- near objects around which the line can wrap or wear line such as small posts trees fence wire or concrete
The line will easily remove grass and weeds from around walls, fences trees and flower beds; but it also can cut the tender bark of trees or shrubs and scar fences To help avoid damage especially to delicate vegetation or trees with tender bark, shorten line to 4-
5 inches and use at partial throttle
• The tip of the line does the cutting You will achieve the best performance and minimum line wear by not crowding the line into cutting area
• Always release throttle trigger and allow engine to retum to idle speed when not cutting
Hold bottom of the semi-automatic head about 3 inches above ground and at an angle

SECTION ON PAGE 2 OF THIS MANUAL
BEFORE YOU BEGIN°
2-CYCLE AIR-COOLED ENGINE OIL
CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) is strongly recommended This oil is specially blended with fuel stabilizers for increased fuel stability (extends fuel life up to 5 times longer) and reduced smoke
IF YOU DO NOT UNDERSTAND THE FUEL
SAFETY SECTION DO NOT ATTEMPT TO
FUEL YOUR UNIT; SEEK HELP FROM
SOMEONE THAT DOES UNDERSTAND
THE FUEL SAFETY SECTION OR CALL
THE CUSTOMER ASSISTANCE HOTLINE
AT 1-800-235-5878.
GASOLINE
The two-cycle engine on this product requires a fuel mixture of regular unleaded gasoline and a high quality
40:1 2-cycle engine oil (AIR-COOLED) for lubrication of
the bearings and other moving parts. The correct fuel/oil mixture is 40:1 (see Fuel Mixture Chart), Too little oil or the incorrect oil type will cause poor performance and
may cause the engine to overheatand seize.
Gasoline and oil must be premixed in a clean approved fuel container. Always use fresh regular unleaded gasoline.
This engine is certified to operate on unleaded gasoline.
IMPORTANT: Experience indicatesthat alcohol blended fuels called gasohol (or using ethanol or methanol) can
attractmoisture,whichleads to oil/gasseparation and for-
mation 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 for 30 days or longer. Drain the gas tank,
then run the fuel out of the carburetorand fuel lines by
startingthe engine and letting itrun untilit stops Use fresh fuel next season See STORAGE instructionsfor addi- tional information Never use engine or carburetorcleaner'
products in the fuel tank or permanent damage may occur
FUEL STABILIZER
Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage Add stabilizer to gasoline in fuel tank or storage container.
Always follow the fuel mix ratio found on the stabilizer container Run engine at least 5 minutes after adding stabilizer to allow the stabilizer to reach the carburetor You do not have to drain the fuel tank for storage if you are using fuel stabilizer
CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) is specially blended with fuel stabilizers If you do not use this Sears oil, you can add a fuel stabilizer (such as
CRAFTSMAN No. 33500) to your fuel tank.
If CRAFTSMAN 2-cycle engine oil (AIR-COOLED) is not available, use a good quality 2-cycle engine oil (AIR-
COOLED) that has a recommended fuel mix of 40:1
IMPORTANT! Do not use:
o AUTOMOTIVE OIL
° BOAT OILS (NMMA, BIA, etc,)
These oils do not have proper additives for 2-cycle AIR-
COOLED engines and can cause engine damage.
GASOLINE AND OIL MIXTURE
Mix gasoline and oil as follows:
• Consult chart for correct quantities..
• Do not mix gasoline and oil directly in the unit's fuel tank,
FOR ONE GALLON:
- Pour 3.2 ounces of high quality, 2*cycle engine oil
(AIR-COOLED) into any empty, approved one gallon gasoline container
° Add one gallon of regular unleaded gasoline to the gallon container,then securely replace the cap.
• Shake the container.
° The mixture is now read,/for use. Fuel stabilizer can be added at this time if desired; follow mixing instruc-
tionson the label.

STORAGE
FUEL SYSTEM
Never use engine or carburetorrcleaner products in the fuel tank or permanent damage may occurto fuel system components.Follow these instructions:
• Drain the fuel from the unit into an approved fuel con.. tainer_
• Drain the fuel lines and carburetor by starting the
engine and letting it tun until it stops_
• Allow the engine to cool before storage.
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 alcohol blended fuels, those that use ethanol or methanol (called gasohol or
oxygenated fuel), can attract moisture and form acidic gas which will damage your engine_ To avoid engine
problems, the fuel system should be emptied before stor- age of 30 days or longer
Fuel stabilizer is an acceptable alternative in minimizing
the formation of fuel gum deposits during storage. Add
stabilizer to the gasoline in the fuel tank or fuel storage
container. Always follow the mix instructions found on
stabilizer containers Run engine at least 5 minutes after
adding stabilizer to allow the stabilizer to reach the car- bureto_
WHEN HANDLING LINE LIMITER. THE
CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) is specially blended with fuel stabilizer. If you do not use this Sears oil, you can add a fuel stabilizer (such as
CRAFTSMAN No. 33500) to your fuel tank_
INTERNAL ENGINE
* Remove spark plug and pour 1 teaspoon of 40:1 2-
cycle engine oil (AIR-COOLED) through the spark plug opening Slowly pull the starter rope 8 to 10 times to distribute oil to inner engine surfaces.
° Replace spark plug with a new one of the recommended
type and heat range. Refer to "Product Specifications"
