do not attempt to fuel your unit. Contact an
authorized service dealer.
FUELING ENGINE
HOW TO START YOUR UNIT
WARNING: Remove fuel cap slowly
when refueling.
WARNING: Avoid any contact with the
muffler. A hot muffler can cause serious burns.
STARTING A COLD ENGINE (or a
warm engine after running out of fuel)
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.
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 petrol 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 con-
tainer. Once oil is added to petrol, shake con-
tainer momentarily to assure that the fuel is thor-
oughly 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)
can attract moisture which leads to separation
and formation of acids during storage. Acidic
petrol can damage the fuel system of an engine
while in storage. To avoid engine problems,
empty the fuel system before storage for 30
days or longer. Drain the fuel tank, start the en-
gine and let it run until the fuel lines and carbure-
tor are empty. Use fresh fuel next season. Nev-
er use engine or carburetor cleaner products in
the fuel tank or permanent damage may occur.

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:
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.
Before trimming, bring engine to a speed suffi-
cient to cut material to be trimmed.
S During light duty cutting.
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.
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:
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.
Trim
S Release the throttle trigger.
S Push and hold the ON/STOP switch in the
STOP position until the engine stops.
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.
8 cm above
ground
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 diame-
ter line. Other sizes of line will not advance
properly and will result in improper cutting
head function or can cause serious 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.
Scalping
CUTTING METHODS
WARNING: Use minimum speed and
do not crowd the line when cutting around
hard objects (rock, gravel, fence posts, etc.),
whichcan damage thetrimmer head, become
entangled in the line, or be thrown causing a
serious hazard.
S The tip of the line does the cutting. You will
achieve the best performance and minimum
line wear by not crowding the line into the
cutting area. The right and wrong ways are
shown below.
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.
11
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.
Mowin
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 strap and keep a firm grip
on the unit with both hands. A properly
adjusted shoulder strap 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.
S Do not raise the engine above your waist as
the blade can come dangerously close to
your body.
OPERATING INSTRUCTIONS FOR
USE WITH WEED BLADE
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 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 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.
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-
