FUEL YOUR UNIT; SEEK HELP FROM

SOMEONE WHO DOES UNDERSTAND

THE FUEL SAFETY SECTION OR CALL

THE CUSTOMER ASSISTANCE HOTLINE

AT 1-800-235-5878,

GASOLINE

The two-cycle engine on thisproduct requires a fuel mix-

ture 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 mix-

ture 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 overheat and seize,

Gasoline and oil must be premixed in a clean approved

fuel container Always use fresh regular unleaded gaso-

line.,

This engine is certified to operate on unleaded gasoline,

IMPORTANT: Experience indicates that alcohol blended

fuels called gasohol (or using ethanol or methanol) can

attract moisture, which leads to oil/gas separation and

formation of acids during storage, Acidic gas can dam-

age the fuel system of an engine while in storage_ To

avoid engine probtems, the fuel system should be emp-

tied before storage for 30 days or longer Drain the gas

tank, then run the fuel out of the carburetor and fuel lines

by starting the engine and letting it run until it stops Use

fresh fuel next season See STORAGE instructions for

additional information Never use engine or carburetor

cleaner products in the luet tank or permanent damage

may occur

FUEL STABILIZER

Fuel stabilizer is an acceptable alternative in minimizing

the formation of fuel gurh deposits during storage, Add

stabilizer to gasoline in fuel tank or storage container,

Always follow the fuel tank or storage container,Always

follow the fuel mix ratio found on the stabilizer container,

Run engine at least 5minutes after adding stabilizer to

aitow the stabilizer to reach the carburetor, You do not

have to drain the fuel tank for storage if you are using

fuel stabilizer,

40:1 2-CYCLE AIR-COOLED ENGINE OIL

CRAFTSMAN 40:1 2-cycle engine oil (AtR-COOLED) is

strongly recommended This oil is specially blended with

fuel stabilizers for increased fuel stability (extends fue! life

up to 5 times longer) and reduced smoke,

tf CRAFTSMAN 40:1 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 ratio of

40:1,

IMPORTANT! Do no use:

. 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, 40:1 2-cycle engine of!

(AIR-COOLED) into an empty, approved one gallon

gasoline container.

o Add one gallon of regular unfeaded gasoline to the gat-

Ion container, then securely replace the cap.

= Shake the container_

,, The mixture is now ready lot use. Fuel stabilizer can be

added at this time if desired; foflow mixing instructions

• For trimming or scalping, use partial throttle to increase

line life, especially:

- during light duty cutting

-near objects around which the line can wrap or wear

Iine such as smalt posts, trees, fence wire or concrete

• The line will easily remove grass and weeds from around

wails, fences, trees and flower beds; but. it also can cut

the tender bark of trees or shrubs and scar fences. To

he_p 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 crowd-

ing the line intocutting area

• Always release throttle trigger and allow engine to return

to idle speed when not cutting

•Hotd bottom of the semi-automatic head about 3 inches
