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 45 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

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 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 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 additional 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.
-12-
These oils do not have proper additives for 2-cycle AIRCOOLED 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 instructionson the label.
