•BLADE THRUST IS a reactionthat only occurs

when using a bladed unit. This reaction can cause
serious injury such as amputation. Carefully study

this sectlon. Itis importantthat you understandwhat

causes blade thrus_ howyou can reduce the chance
ofIt occurring; and howyou can remain in:controlof

the unitif blade thrustcocurs.

WHAT CAUSES BLADE THRUST?

Blade Thrustcanocourwhen the spinning blade_€on_

tacts an object that it does not cut. This contact

causes the blade to stop for an instantand then sud-
denly move or =thrust"away from the object that was

hit. The "thrusting" reaction can beviolent enough to
cause the operator to be propelled in any direction

and lose control ofthe unit. The uncontrolled unit can
cause serious injury ifthe blade contacts the opera-

tor or others.

WHEN DOES BLADE THRUST OCCUR?

Blade thrustcan occur without warning if the blade
snags, stalls, or binds. This is more liketyto occur in
areas where it isdifficult to see the material being cut.
By using the unit properly, the occurrence of blade

thrust will be reduced and the operator will be less

likely to lose control.
The forward tip on the metal blade shield helps to re-

duce .the occurrence of blade thrust but cannot pre-

vent the occurrence. The operator must follow all
warnings and safety instructions in this manual to
lessen the chance of blade thrust ocourdng and to

maintain control of unit ifthe reaction does occur.

- 14-

REDUCE THE CHANCE OFBLADETHRUS'r

Cut vegetation up to 2 1/2" diameter saplings with
saw blade.

• Cutonlygrass, weeds, andwoedybrushuptol!2" in
diameter with the brush tfi-bisde:Do:nottet theblade

contact matedal it cannot cutsuch as stumps, rocks,

.fences, metal, etc., or clusters of hard, woody brush

having a diameter graater than 2 1/2 inches.

Keep the blade sharp. A dull blade is more likely to
snag and thrust.

• Cut only at full throttle. The blade has maximum cut-
ting power at full throttle and is less likely to bind or

stall.
=Feed" the blade deliberately and nottoo rapidly. The

blade can thrust away if it is fed too rapidly.
Cut only from your fight to your teft.

OPERATING / USE TIPS (Figure 20 )

To establish a rhythmic cutting procedure:

• Plant feet firmly,comfortably apart.

• Cutwhile swingingthe upperpart ofyour body from dght

to left.
Move forward to the next area to be cut after the return
swing and plant feet once more.

• Use the 8 o'clockto 10 o'clock position for cutting.

• Bringthe engine tofull throttlebefore entering the mate-

rialto be cut. The blade has maximum cutting power at

fullthrottle end isless likelytobind, stall,or cause blade
thrust, which can resultin serious injuryto the operator

or others. Refer to =Guard Against Blade ThrustS; ....

• Alwaysreleasethrottletriggerandallowenginetoretum

to idle speed when not cutting.

• Cut onlyfrom your righttoyour left. Swinging the unitin

the same direction as the blade spins increases the cut-

ting action.

To reduce the chance of material wrapping around the

blade, follow these steps:

• Cut at full throttle.

• Swing the unitinto material to be cut from your right
toyour left.

• Avoid the material just cut as you make the return
swing.

GASOLINE

The two_-cycleengineonthis product requiresafuel mixture

of regular unleaded gasoline and a high quality 2-cycle eri-
gine oil (AIR-COOLED) for lubricationof the bearings and
other moving pads. The correctfuel/oil m_um is40:1 [see

Fuel Mixture Chart). Toolittle oil or the incorrect oiltype will

cause poor performance and may cause the engine to over-

heat and seize.

Gasoline and oil must be premixed ina clean approved fuel

container. Always use fresh regular unleaded gasoline.

This engine has been certified to operate on unleaded

gasoline.

2-CYCLE OIL:

CRAFTSMAN 40:1 2 cycle oil is strongly recommended.
Thisoil isspeciallyblended withfuel stabilizersfor increased

fuel stability (extends fuel life up to 5 times longer) and

reduced smoke.
If CRAFTSMAN 2 cycle oil is not available, use a good

quality 2 cycle AIR-COOLED engine oil that has a

recommendedfuel mix40:1.

IMPORTANT!- Do not use:

• AUTOMOTIVE OIL

• BOATOILS (NMMA. BIA. etc.)

These oilsdo nothaveproper additivesfor2-cyole, AIR-

COOLED engines and can cause engine damage.

GASOLINE AND OIL MIXTURE

Mix gasoline and oil as follows:

• Consultchart for correct quantities.

Do not mix gasolineand oil directlyin the fuel tank.

FOR ONE GALLON:

IMPORTANT: Experience indicates that alcohol

blended fuels called gasohol (or using ethanol or metha-

nol) can attract moisture, Whichleads to oil/gas separa-
tion and formation of acids during storage. Acidic gas
can damage the fuel system of an engine while in stor-

age. To avoid engine problems, the fuel system should
be emptied before storage for30 days:or longer. -Drein
the gas tank, then run the fuel.out.of the carburetor.and
fuel lines by starting the engineand 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 fuel tank or perma-

nent damage may occur.

FUEL STABILIZER

Fuel stabilizer isan acceptable alternative in minimizing the
formation of fuel gum depositsduring 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.

Pour 3.2 ounces of high quality, 2--cycle engine oil
intoan empty, approved one gallon gasoline contain-

er.

Add one gallon of regular unleaded gasoline to the
gallon container, then securely replace the cap.
Shake the containermomentarily.

The mixture is now ready for use. Fuel stabilizer can

be added at thistime ifdesired; follow mixing instruo-
tions on the label.

_ WARNING:

MAKE CARBURETOR ADJUSTMENTS

WITH THE LOWER END SUPPORTED TO

PREVENT TRIMMER HEAD FROM CON;
TACTING ANY OBJECT. HOLD UNIT WITH

YOUR HAND.
THE TRIMMER HEAD WILL BE SPINNING

DURING MOST OF THIS PROCEDURE.

CARBURETOR PRESETS (Fig. 39)

The Carburetor has three adjustingscrews:
L = Low speed mixture adjusting screw

H= High speed mixture adjusting screw

T = Idle speed adjusting screw

If your engine willnot start due to suspected improper car-
bt.iretoradjustment, the following presets may be required.
If used, it is recommended that all steps within the adjust-
ment procedure be completed in order to assure a prop-
edy set carburetor. If presets are not needed, proceed to
section =Idle Speed Adjustment."

Very small adjustments can affect engine pedorrnance. It

is important to turn the screw a very small amount per

ad._ustmentand test performance before making further

aojustments. Eacn adjustment should be no more than
the widthof the slot in the adjusting screw.
° Turn both of the mixture screws (marked "H" and "L")

- clockwise until they stop. Do not force the screws as

damage can occur. Then, turn each screw one (t) full

turn counterclockwise.

IMPORTANT'DO NOT OPERATE ENGINE AT FULL

THROTTLE FOR PROLONGED PERIODS WHILE:

• MAKING HIGH SPEED ADJUSTMENTS AS DAMAGE

,_; ,TO,THE ENGINE CAN OCCUR.

: '• Make a test cut in grass.

--,, Based on performance of the unit while cutting, adjust
the high speed mixture screw in 1116 turn,increments

as follows:

- Clockwise if unit smokes or loses power while cutting.

Do not adjust for best power by sound or speed, but

judge by how well the unit performs during,operation.

- Counterclockv_se if the unit has speea whilenot cut-
ting, but dies or lacks power whilecutting.

: Repeat the test cut in grass.

Continue with 1/16 turn adjustments until the unitper÷
formance is acceptable while cutting.

• After completing adjustments, check for acceleration.

• If unit accelerates properly no further adjustments are
necessary. If notproceed to acceleration check.

ACCELERATION CHECK

, Ifthe engine dies or hesitates insteadofsccelerating, turn

the Low Speed Mixture Screw 1/16 of a turn at a time
counterclockwise until you have smooth acceleration.

• Check the idle speed for stability and that the blade or
trimmer headdoes not turn. Adjust as necessary.

• Recheck for smooth acceleration and stable idle.

• Repeat process as necessary for acceptable perfor-

mance.
