CUTTING SAFETY

WARNING: Inspect the area before

each use. Remove objects (rocks, broken
glass, nails, wire, etc.) which can be thrown
by or become entangled in line. Hard objects
can damage the trimmer head and be thrown
causing serious injury.
S Use only for trimming, scalping, mowing

and sweeping. Do not use for edging, prun­ing or hedge trimming.

S Keep firmfooting andbalance. Do not over-

reach.

S Keep all parts of your body away from muf-

fler and spinning line. Keep engine below

SPECIAL NOTICE: Exposure to vibra-

tions through prolongeduse of gasoline pow­ered hand tools could cause blood vessel or
nerve damage in the fingers, hands, and
joints of people prone to circulation disorders
or abnormal swellings. Prolonged use in cold
weather h asbeen linked toblood vessel dam­age in otherwise healthy people. If symptoms
occur such as numbness, pain, loss of
strength, change in skin color or texture, or
loss of feeling in the fingers, hands, or joints,
discontinue the use of this tool andseek med­ical attention. An anti-vibration system does
not guarantee the avoidance of these prob­lems. Users who operate power tools on a
continual and regular basis must monitor
closely their physical condition andthe condi­tion of this tool.

WARNING: Make sure unitis proper-

ly assembled and all fasteners are secure.
Examine parts for damage. Do not use dam­aged parts.
It is normal for the fuel filter to rattle in the
empty fuel tank.
Finding fuel or oil residue onmuffler is normal
due to carburetor adjustments and testing
done by the manufacturer.

ADJUSTING THE HAND LE

WARNING: When adjusting the assist

handle, besure it remains above thesafety label
and below the mark or arrow on the shaft.

1. Loosen wing nut on handle.

2. Rotate the handle on the shaft to an up­right position; retighten wing nut.

ATTACHING THE SHIELD

WARNING: The shield must be prop-

erly installed. The shield provides partial
protection from the risk of thrown objects to
the operator and others and is equipped with
a line limiter which cuts excess line. The line
limiter (on underside of shield) is sharp and
can cut you.

1. Remove nut from shield.

2. Insert bracket into slot on shield.

3. Pivot shield until bolt passes throughhole
in bracket.

4. Reinstall nut and tighten securely with
wrench (provided).

OPERATION

WARNING: Be sure to read the fuel

information in the safety rules before you be­gin. If you do not understand the safety rules,
do not attempt to fuel your unit. Contact an
authorized service dealer.

FUELING ENGINE

WARNING: Remove fuel cap slowly

when refueling.
This engine is certified to operate on unleaded

gasoline. Before operation, gasoline must be
mixed with a good quality 2-cycle air-cooled en­gine oil. We recommend McCulloch® brand oil
mixed at a ratio of 40:1 (2.5%). A 40:1 ratio is
obtained by mixing 5 liters of unleaded gasoline
with 0,125 liter of oil. DO NOT USE automotive
oil or boat oil. These oils will cause engine dam­age. When mixing fuel, follow instructions
printed on oil container. Once oil is added to
gasoline, shake container momentarily to as­sure that the fuel is thoroughly mixed. Always
read and follow the safety rules relating to fuel
before fueling your unit.

IMPORTANT

Experience indicates that alcohol blended
fuels (called gasohol or using ethanol or
methanol) canattract moisture which leads to
separation andformation ofacids during stor­age. Acidic gas can damage the fuel system
of anengine while in storage. To avoidengine
problems, empty the fuel system before stor­age for 30days or longer. Drain the gas tank,
start theengine andlet itrun untilthe fuellines
and carburetor areempty. Use fresh fuelnext
season. Never use engine or carburetor
cleaner productsin thefuel tank or permanent
damage may occur.

HOW TO STOP YOUR UNIT

S To stop the engine, move the ON/OFF

switch to the OFF position.

HOW TO START YOUR UNIT

WARNING: Always wear eye protec-

tion and hearing protection. Never lean over
the trimmer head. Rocks or debris can rico­chet or be thrown into eyes and face and
cause blindness or other serious injury.
Do not run the engine at a higher speed than
necessary. The cutting line will cut efficiently
when the engine is run at less than full throttle.
At lower speeds, there is less engine noise and
vibration. The cutting line will last longer and will
be less likely to “weld” onto the spool.
Always release the throttle trigger and allow the
engine to return to idle speed when not cutting.
To stop engine:

S Release the throttle trigger.
S Move the ON/OFF switch to the OFF posi-

tion.

TRIMMER LINE ADVANCE

Advance line by tapping the bottom of the cut­ting head lightly on the groundwhile engineis
running at full speed. The metal line limiter
blade attached to the guard will cut the line to
the proper length.

WARNING: Use only 2 mm diameter

line. Other sizes andshapes ofline will not ad­vance properly andwill result inimproper cut­ting headfunction orcan causeserious injury.
Do not use other materials such as wire,
string, rope, etc. Wire can break off during
cutting and become a dangerous missile that
can cause serious injury.

CUTTING METHODS

WARNING: Use minimumspeed and

do not crowd the line when cutting around
hard objects (rock, gravel, fence posts, etc.),
which candamage thetrimmer head,become

S The line will easily remove grass and

weeds fromaround walls, fences, trees and
flower beds, but it also can cut the tender
bark of trees or shrubs and scar fences.

S For trimming or scalping, use less than full

throttle to increase line life and decrease
head wear, especially:

S During light duty cutting.
S Near objects around which the line can-

wrap such as small posts, trees or fence
wire.

S For mowingor sweeping, use full throttle for

a good clean job.
TRIMMING -- Hold the bottom of the trimmer
head about 80 mm above the ground and at
an angle. Allow only the tip of the lineto make
contact. Do not force trimmer line into work
area.

Trimming

80mm above

ground
SCALPING -- The scalping technique removes
unwanted vegetation. Hold the bottom of the
trimmer head about 80 mm above the ground
and at an angle. Allow the tip of the line to strike
the ground around trees, posts, monuments,
etc. This technique increases line wear.

6

MOWING -- Your trimmer is ideal for mowing
in places conventional lawn mowers cannot
reach. In the mowing position, keep the line
parallel to the ground. Avoid pressing the
head into the ground as this can scalp the
ground and damage the tool.

MAINTENANCE

SWEEPING -- The fanning action of the rotat­ing line can be used for a quick and easy
clean up. Keep the line parallel to and above
the surfaces being swept and move the tool
from side to side.

WARNING: Disconnect the spark

plug before performing maintenance except
for carburetor adjustments.

functions properly by moving the switch to
the OFF position. Make sure engine stops;
then restart engine and continue.

S Fuel Tank -- Discontinue use of unit if fuel

tank shows signs of damage or leaks.

S Debris Shield -- Discontinue use of unit if

debris shield is damaged.

INSPECT AND CLEAN UNIT A ND
LABELS

S After each use, inspect complete unit for

loose ordamaged parts. Clean the unit and
labels using adamp cloth with a mild deter­gent.

S Wipe off unit with a clean dry cloth.

CLEAN AIR FILTER

A dirty air filter decreases engine perform­ance and increases fuel consumption and
harmful emissions. Always clean after every
5 hours of operation.

1. Clean the cover and the area around it to

keep dirt from falling into the carburetor
chamber when the cover is removed.

2. Remove parts as illustrated.

NOTE: Do not clean filter ingasoline orother

flammable solvent to avoid creating a fire haz­ard or producing harmful evaporative emis­sions.

3. Wash the filter in soap and water.

4. Allow filter to dry.

5. Add a few drops ofoil tothe filter;squeeze

the filter to distribute oil.

6. Replace parts.

CARBURETOR ADJUSTMENT

WARNING: Keep others away when

making idle speed adjustments. The trimmer
head will be spinning during this procedure.
Wear your protective equipment and observe
all safety precautions.
The carburetor has been carefully set at the
factory. Adjustments may be necessary if you
notice any of the following conditions:
S Engine will not idle when the throttle is re-

leased.
Make adjustments with the unit supported so
the cutting attachment is off the ground and
will not make contact with any object. Hold
the unitby handwhile runningand makingad­justments. Keep all parts of your body away
from the cutting attachment and muffler.

Idle Speed Adjustment

Allow engineto idle.Adjust speed untilengine
runs without stalling (idle speed too slow).
S Turn idle speed screw clockwise to in-

crease enginespeed if enginestalls or dies.
S Turn idle speed screw counterclockwise to

decrease engine speed.
