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 reducethechance
ofIt occurring;and howyou can remain in:controlof
the unitif blade thrustcocurs.
WHAT CAUSES BLADE THRUST?
Blade Thrustcanocourwhen thespinning 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 be violent 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 occurin
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 ocourdngand to
maintain controlof unitifthe reaction does occur.

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 itis fed too rapidly.
Cut onlyfrom your fight to your teft.

OPERATING / USE TIPS (Figure 20 )
To establish a rhythmic cutting procedure:
Plant feet firmly, comfortablyapart.
Cutwhile swingingthe upperpart ofyourbody from dght

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 tofullthrottlebefore 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_-cycleengine onthis productrequiresa fuel mixture
of regular unleaded gasolineand 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 oilor the incorrectoiltype will
cause poor performance and may cause the engine to over-
heat and seize.
Gasoline and oil mustbe premixed in a 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.
Thisoilisspeciallyblended 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 mix 40:1.
IMPORTANT!- Do not use:
AUTOMOTIVE OIL
BOATOILS (NMMA. BIA. etc.)
These oilsdo nothaveproperadditivesfor2-cyole, AIR-
COOLED engines and can cause engine damage.
GASOLINE AND OIL MIXTURE
Mix gasoline and oilas follows:
Consultchart for correct quantities.
Do not mix gasolineand oil directlyin thefuel 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 ifyou 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 addedat thistime ifdesired; follow mixing instruo-
tions on the label.

of this manual should be checked at least once each
season.
Once a year, replace the spark plug, replace air filterele-
ment and check blades for wear. A new spark plug and a
clean/new air filter element assures proper air-fuel mix-
ture and helps your engine run better and last longer.
