CUTTING SAFETY
SPECIAL NOTICE: Exposure to vibrations
through prolonged use of petrol powered hand
tools could cause blood vessel or nerve dam-
age in the fingers, hands, and joints of people
prone to circulation disorders or abnormal swell-
ings. Prolonged use in cold weather has been
linked to blood 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
and seek 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 and the condition
of this tool.
WARNING: Inspect the area to be cut
before each use. Remove objects (rocks,
broken glass, nails, wire, string, etc.) which
can be thrown or become entangled in the
blade or trimmer head.

This engine is certified to operate on unleaded
petrol. Before operation, petrol must be mixed
with a good quality 2--cycle air--cooled engine oil
designed to be mixed at a ratio of 40:1. A 40:1
ratio is obtained by mixing 5 liters of unleaded
petrol with 0,125 liter of oil. DO NOT USE auto-
motive oil or marine oil. These oils will cause en-
gine damage. When mixing fuel, follow instruc-
tions printed on oil container. Once oil is added
to petrol, 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.

S Keep unit below waist level.
S Maintain full weight of tool on both shoulders.
S Without bending over, keep the blade or
trimmer head near and parallel to the ground
and not crowded into material being cut.
S The 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.
OPERATING INSTRUCTIONS FOR
USE WITH TRIMMER HEAD
S For trimming or scalping, use less than full
throttle to increase line life and decrease head
wear, especially:
S During light duty cutting.
WARNING: Always wear eye protec-
tion. 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.
S Near objects around which the line can
wrap such as small posts, trees or fence
wire.
S For mowing or sweeping, use full throttle for a
good clean job.
Before trimming, bring engine to a speed suffi-
cient to cut material to be trimmed.
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.
TRIMMING -- Hold the bottom of the trimmer
head about 8 cm above the ground and at an
angle. Allow only the tip of the line to make
contact. Do not force trimmer line into work
area.

TRIMMER LINE ADVANCE
Advance line by tapping the bottom of the cut-
ting head lightly on the ground while engine is
running at full speed. The metal line limiter
blade attached to the guard will cut the line to
the proper length.
SCALPING -- The scalping technique re-
moves unwanted vegetation down to the
ground. Hold the bottom of the trimmer head
about 8 cm 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.
WARNING: Use only 2,4 mm diameter
line. Other sizes of line will not advance properly
and can cause serious injury. Do not use other
materials such as wire, string, rope, etc. Wire

S WHEN BLADE THRUST OCCURS --
Blade Thrust can occur without warning if
the blade snags, stalls, or binds. This is
more likely to occur in areas where it is
difficult 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.
Scalping
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.
Mowin
S Cut only grass, weeds, and woody brush up
to 1 cm in diameter with the weed blade. Do
not let the blade contact material it cannot cut
such as stumps, rocks, fences, metal, etc., or
clusters of hard, woody brush having a
diameter greater than 1 cm.
S Keep the blade sharp. A dull blade is more
likely to snag and thrust.
S Cut only at full throttle. The blade will have
maximum cutting power and is less likely to
bind or stall.
SWEEPING -- The fanning action of the rotat-
ing linecan beusedto blow away loosedebris
from an area. Keep the line parallel to and
above the area surface and swing the tool
from side to side.
S “Feed” the blade deliberately and not too
rapidly. The blade can thrust away if it is fed
too rapidly.
S Cut only from your left to your right. Cutting on
right side of the shield will throw debris away
from the operator.
Sweeping
S Use the shoulder harness and keep a firm
grip on the unit with both hands. A properly
adjusted shoulder harness will support the
weight of the unit, freeing your arms and
hands to control and guide the cutting motion.
S Keep feet comfortably spread apart and
braced for a possible sudden, rapid thrust of
unit. Do not overreach. Keep firm footing and
balance.
S Keep blade below waist level; it will be
easier to maintain control of unit.
OPERATING INSTRUCTIONS FOR
USE WITH WEED BLADE
S Do not raise the engine above your waist as
the blade can come dangerously close to
your body.
S Blade Thrust is a reaction that only occurs
when using a bladed unit. This reaction can
cause serious injury such as amputation.
Carefully study this section. It is important that
you understand what causes blade thrust,
how you can reduce the chance of its
occurring, and how you can remain in control
of unit if blade thrust occurs.
S Do not swing unit with such force that you
are in danger of losing your balance.
Bring the engine to cutting speed before enter-
ing the material to be cut. If the blade does not
turn when you squeeze the throttle trigger, make
sure shaft is fully inserted into the engine.
Always release the throttle trigger and allow
engine to return to idle speed when not cut-
ting. The blade should not turn while the en-
gine is running at idle. If the bladeturns at idle,
do not use your unit. Refer to the CARBURE-
TOR ADJUSTMENT section or contact your
authorized service dealer.
S WHAT CAUSES BLADE THRUST -- Blade
Thrust can occur when the spinning blade
contacts an object that it does not cut. This
contact causes the blade to stop for an instant
and then suddenly 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 of the unit. The uncontrolled unit
can cause serious injury if the blade contacts
the operator or others.
S Maintain good firm footing while using the
unit. Do this by planting feet firmly in a
comfortable apart position.
S Cut while swinging the upper part of your
body from left to right.
11
S As you move forward to the next area to cut,
be sure to maintain your balance and footing.
WARNING: The operator or others
must not try to clear away cut material withthe
engine running or the blade turning to avoid
serious injury. Stop engine and blade before
removing materials wrapped around blade or
shaft.

chine maintenance is not carried out correctly
and if service and/or repairs are not carried
out professionally. If you need further infor-
mation, please contact your nearest autho-
rised service dealer.
CLEAN AIR FILTER
A dirty air filter decreases engine perform-
ance 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.
