C. STARTING INSTRUCTIONS
1. HOW FUEL INJECTION STARTING TM WORKS
FUEL INJECTION STARTINGTMprovides a
quick, start feature by. injecting a precise
amount of fuel .directly into the. carburetor
manifold which provides a rich fuel mix for the
first few seconds of operation.
INJECTOR BuI-r ON
-.•Each-time the injector button is pressed and
-.+.:_- ---released, fuel is forced'from'the fuel tank to
'- the accumulator c:hamber.
•The accumulator chamber provides a sec-
ondary fuel supply until the carburetor can
obtain fuel through the primary line
•When the accumulator chamber is full, fuel
is injected into the carburetor manifold to
provide a rich mixture for starting.
Excess fuel escapes through a drain to
prevent the engine from flooding if the
injector button is pressed too many times.
As a result, a few drops of fuel may appear
on the ground during the starting procedure.
CARBURETOR DRAIN
FUEL INJECTION STARTING DEVICE (PATENT PENDING)
Figure 6
The number of injections required will
depend on temperature conditions and the
time elapsed since the engine was last
started.
2. STARTING PROCEDURE 3. IMPORTANT POINTS TO REMEMBER
a. Extenda minimumof4inchesoflinefromthe
cutting head to provide the correct load on the
engine.
b. Stand in the operating position, and place
the cutting head on the ground. Figure 9.
This insures that fuel will flow into the in-
jector pump.
c. Move the ignition switch to the "ON" posi-
tion. Figure 7.
d. Grip the rear handle with your right hand,
squeezing and keeping the throttle trigger
fully depressed until the engine runs
smoothly.
e. Press the injector button down fully allow-
ing the button to return completely after
each pressing. Follow conditions and injec-
tions listed.

[CAUTION: ] If more than a drop ortwo of fuel
spills on the ground move unit away to another
area for starting to avoid creating a fire hazard.
g. Pull starter rope quickly and sharply until
engine starts.
NOTE: If engine attempts to start but dies
or does not start after 5 (five) pulls, press
injector one more time and pull starter
rope again.
h. The engine will run roughly when first
started. It is important to keep the throttle
trigger fully depressed until the engine
runs smoothly (10 seconds or less)
i. If theengine starts but the cutting head does
not tum with the throttle trigger depressed,
make sure the drive shaft housing is properly
seated in the engine shroud. See "Ddve Shaft
Housing",page 5.
/_WARNING
The cutting head must not turn when the engine
runs at idle speed. Refer to "Carburetor Adjust-
merits", page 9 for correction.
a. If the engine starts to die immediately after
starting, keep throttle trigger depressed
and press injector button once with fore-
finger to give unit additional fuel.
b. If the engine is stopped momentarily (less
than 5 minutes), it probably will not require
an injection.
c. If unit runs out of fuel or is drained for stor-
age "First Starting" procedure may be re-
quired because the system will be dry.
d. After starting and engine runs smoothly,
keep unit running at half speed until engine
is warmed up to proper idle.
eUsinggasoline orfuelmix over2 months old
will cause the engine to be difficult or impos-
sible to start!
4. COLD WEATHER STARTING
(Below 30 ° F)
a. Follow "Starting Procedure" through step
"d", then as below.
b. Press injector button down fully six (6}
times allowing the button to return com-
pletely after each pressing.
c. Pull starter rope quickly and sharply until
unit starts. Keep trigger fully depressed.
d. If unit does not start in four pulls or attempts
to start but dies, press injector button an
additional four times.
e. Continue pulling starter rope four pulls.
If unit fails to start, repeat step d., above.
f. It is important not to release trigger until
unit runs smoothly.
g. Once unit has started, immediately press
injector button two additional times to keep
unit running until it warms up.
h. in extremely cold weather, it will be very
difficult to flood the unit, so if the unit
doesn't start-quickly, do not hesitate to
press injector button for additional fuel.
i. For starting warm engine in cold tempera-
tures, press injector button once before
starting.

Figure 10 9
USING YOUR UNIT
Your Trimmer is equipped with a semi-automatic advancing
cutting head that cuts with the tip of a monofilament nylon line.
The nylon cutting 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. For this reason, it is very
important to learn the proper techniques of cutting
around and near objects.
The nylon cutting line will wear faster and will
require being advanced more frequently when you
are cuttingagainst rocks, bricks,concrete, metal fences,
etc., than against trees or wooden fences.
The cuttinghead will wear prematurely:
--if allowed to continuously contact the ground
during normal cutting.
--if the line limiter is not kept sharp.
WARNING
Use only flexible, non-metalic, monofllament cutting
line. Do not use other materials such as rope, wire, etc.
Wire can break off during cutting and become a
dangerous missile.
A. OPERATING INSTRUCTIONS
1. Read your Operator's Manual.
Make certain you completely understand and follow
all safety rules, precautions, and operating instruc-
tions before operating the unit.
,Always wear eye protection. The
splash deflector/line limiter will not

thrown or ricocheting into the eyes
and face which can result in loss of vision or
serious personal injury.
3. Dress safely in long pants-and wear boots or
safety shoes.
Do not wear Iooseclothing, jewelry, short pants or
sandals; or go barefoot.
4. Check the unit before operation.
Lookfor worn,loose, missing,ordamaged parts. Donot
use untilthe unit is inproperworking order.
,Inspect the area to be cut.
Remove all debris and objects that can ricochet, be
thrown,become entangledinthe cuttingheadorother-
wise cause injuryor damage duringcutting.
6. Keep observers, children, bystanders, and animals
safely away.
Beforestartingthe engineandduringoperation,make
certainchildren,animalsandbystandersare awayfrom
the workarea -a minimum of 30 feet(10meters).
B. ADVANCING THE CUTTING LINE
• The cutting line is extended semi-automatically by
tapping thebottom ofthe head on the ground with
.the engine_running.
k.• Approximately 2 Inches oflinelsextended each
time the tap button is tapped on the ground,
•The line,miter on the splash deflector cuts line to
amaximum allowable length.
•The most efficient cutting line length Is the max-
imum length allowed by the line Iimiter.
1. To advance line:
a. Operate the engine at fullthrottle.
b. Hold cutting head parallel to and above the
grassy area of the ground.
c. Tap the cutting head lightly on the ground one
time. See Figure 12. Approximately 2 inches of
line will be advanced after each tap.
NOTE: If the line is worn down to two inches or
less, more than one tap may be required to
obtain the most efficient line cutting length.
2. Always keep the splash deflector in place when
the unit Is being operated.
-3. Keep the line Iimitersharpfor fast, easycut-off.
See page 13for sharpening instructions.
NOTE: Always tap the cutting head ona grassy
area of the ground. Tapping on surfaces such
as concrete or asphalt can cause excessive
wear to the cutting head.

Hold the cutting head at a 30 degree angle to the
cutting area for efficient trimming. Do not force the
cutting line intothe work area. Allowt.hetip ofthe line
to do the cutting.
2, EDGING -- Figure 15
Adjustyourtrimmer foredging byturningtheengine
upside down so the drive shaft housing angles out
rather than down. Rotate the assist handle on the
shaft, placing it in an up, usable position. Hold the
cutting head above the area to be edged as shown
and operate the throttle trigger with your thumb,

ting head continuously contact the groundas this can
cause damage toyourunitaswell asscalpthe ground.
4. SCALPING -- Figure 17
Toremove unwanted vegetation around trees, posts,
monuments, etc., maintain a 30degree angle with the
cutting head and allow the tip of thecutting line to
strike the ground.
NOTE: Increased line wear is to be expected when
using scalping techniques.
,SWEEPING -- Figure 18

AIR FILTER CARE
A dirty air filter decreases engine performance
and increases fuel consumption,
Clean the Air Filter:
• Frequently,
•Always after 5 tanks of fuel or 5 hours of opera-
tion, whichever is less,
Follow these steps:
1, Removetheairfilter(Iocatedatthebettom, rearofthe
Engine Shroud) see page 2.
2, Wash in soap and water.
ICAUTION:] Do not clean filter in gasoline
or other flammable solvent to avoid creating
a fire hazard.
3. Squeeze filter dry.
4, Replace the air filter.
I CAUTION: fThe air filter must be fitted into
the corners of the housing to avoid engine
damage.
Cll FUEL TANK UPKEEP
Never use gasoline that ismore than 2 months
old in a fuel mixture. Gasoline begins to break
down after a period of time and will form com-
pounds that cause hard starting and damage in
2-cycle engines.
,
2.
.
inspect the unit for fuel leaks each time it is
used. Repair or replace parts as necessary.
Using gasoline or fuel mix over 2 months old will
cause the engine to be difficult or impossible to
startl
Drain the fuel tank or allow the unit to run out
of fuel before storing for 30 or more days.
NOTE: "First Starting" procedure may be
required fora unit that runs out of fuel or from
which fuel is drained, See "Starting Instruc-
tions", page 8.
D. STARTER ROPE REPAIR
• Repair the starter rope If the rope breaks next
to the pulley.
• Replace the starter rope if the rope breaks 2-3
inches away from the pulley as the rope will be
too short to repair properly.
/_WARNING
Always wear eye protection when ser-
vicing the starter rope. The recoil spring,
located beneath the pulley, is under ten-
sion. If the spring pops out, serious per-
sonal injury can result.
•To repair or replace:
NOT_ Use caution when separating the
fan housing from the shroud to avoid
breaking or damaging the fuel line fittings.
1_ Drain all fuel from tank.
2. Remove the four (4) screws from fan
housing. Figure 28.
3. Carefully separate fan housing from shroud-
about one (1) inch.
4. Disconnect fuel lines from fittings.
5. Disconnect ignition module wires. Figure
28.
6. Slide high tension lead grommet from slot,
in fan housing.
7. Separate the fan housing completely from
the shroud.
8. If the starter rope is not broken, release
the spring tension by pulling about 12
inches of rope from the pulley and catch
the rope in the notch as shown. Figure 30.
NOTE: The tension on thestarter spring
will be released if the rope has broken.
9. Remove screw and pulley very carefully.
Figure 29. The recoil spring which lies
beneath the pulley must stay in the hous-
Ing, flat against t6e bottom. Itthe spring Is
disturbed, it will require oonsiderable time
and effort to reinstall. Twist the pulley
gently clockwise ,,,,-]& ' as you pull up to
release the spring.
10. Moveawayfromthefuel tankand melttheend0f
the new rope to go intothe pulley,
11. Allowthe meltedendtoddponce, thenwhile rope
