•no sparks or flames.
c. Use a container approved for fuel.
;d. Do not smoke or allow smoking near fuel or the
tool or while using the tool.
e. Wipe up all fuel spills before starting engine.
f. Move at least 10feet away from fueling site before

i. Store tool and fuel in an area where fuel vapors
cannot reach sparks or open flames from water
heaters, electric motors orswitches, furnaces, etc.
2. FUEL MIXTURE
•Your tool is powered by a two-cycle engine which
requires a fuel mixture of regular unleaded
•gasoline and a high quality engine oil specially
•made far 2-cycle, air cooled engines. The internal
design of the 2-cycle engine requires lubrication of
moving parts. Lubrication is provided when the
recommended mixture of gasoline and oil is used.
Gasoline must be clean and not over two months
old. Gasoline will chemically break down and form
compounds that cause hard starting and damage in
2-cycle engines.
•The correct measure of gasoline to oil is very
important. Too much oil in the mixture will fou!the
spark plug.
]CAUTION:[ Too little oil or incorrect oil will
cause the engine to overheat and seize.
Always mix the fuel thoroughly in a container
since gasoline andoil do notreadily combine. Do not
mix gasoline and oil directly in the fuel tank.
3. USE THE FOLLOWING ONLY:
(16 parts gasoline to 1part oil)
,t.no NoTUSE:
• BIA oIL (Boating Institute of America) --
-- Does not have proper additives for air-cooled
2-cycle engines and can cause damage to your
unit. "
• AUTOMOTIVE OIL-
-Does not have proper additives for 2-cycle engines
and can cause damage.
•GASOLINECONTAINING AI_OHOL --
High Test, Premium or Gasohol (Ethanol or
Methanol)
-- Stiffenscritic'_ carburetor fuelmetering elements
and causes engine damage from overheating.
-- Increases vapor lock (causes hard starting).
Attracts water causing corrosion damage.
5.HOW TOMIX FUEL AND FILL TANK
a. Pourl/2 gallon regular unleaded gasoline into an
approved, markedconminer.Do not mix gasoline
and oil directly b7the fi_el tank.
b. Add entire measureofengine oil.
c. Cover container tightly and shake for one minute.
d. Add remainder of gasoline.
e. Cover container tightly and shake again.
f. Slowly remove fuel container cover.

C. CUTTING METHODS
•The tip of the line does the cutting. Allow the line to
trim at its own pace. You will achieve better results by
.... noteroding the line into the cutting area. The right and
wrong way are shown in Figure/3.
• The line will easily remove grass and weeds from
around walls, fences, trees and flower beds, but it
also can cut the tender bark oftrees or shrubs and scar
fenceA Tohelp avoid damage to vegetationor trees with
tender bark, shorten line to 4-5 inches and use tess than
full throttle.
•The line will wear faster and willneedto be advanced
•more ti_uenfly whenyou are cutting against rocks,
bricks, concrete, metal fences, etc., than when cut-
ring against trees or wooden fences.
•For trimmingor scalping, use less than full throttle
to increase line life and decrease head wear.
-- during light duty cutting.
--next to rocks, bricks, concrete, metal fences, etc..
e-Formowingorsweeping, use full throttle for a good
clean job.
•Avoid letting the trimmer head continuomly contact
_the ground during normal cutting. Constant contact
will causetrimmer head damage and premature wear.
Figure 13
Always wear eye protection. Never lean over the trim-
met head. Rocksor debriscan ricochet orbethrmm into
eyes and face and cause blindness or other serious injury.
1. TRIMMING ,-. Figure 14
Hold the tap button about 3 inches above the ground and
tilt thetrimmer head atan angle. Allowthe tip oft.he line
todothe cutting. Do not force the trimmer line into the
workarea.
2. SCALPING -- Figure 15
•The scalping technique removes unwanted vegetation.
Hold the tap button about 3 inches above the ground and
tilt the trimmer head at an angle° Allow the tip ofthe line
to strike the ground around trees, posts, monuments,
etc. This technique increases line wear.
3. MOWING -- Figure 16
Yo_artrimmer is ideal formowing in places conventional
lawn mowers cannot reach. In the mowing position,
keep the line parallel tothe ground, Avoid pressing the
head into the ground as this _:anscalp the ground and
..damage the tool.
4. SWEEPING -- Figure 17
The fanning action of the rotating line can beused for
a quick and easy clean up. Keep the line paxallei to and
above the surfaces being swept and move the tool from
side to side.
