OPERATION
WARNING: Be sure to read the fuel
information in the safety rules before you be-
gin. 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 en-
gine 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 dam-
age. When mixing fuel, follow instructions
printed on oil container. Once oil is added to
gasoline, shake container momentarily to as-
sure 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)
can attract moisture which leads to separation
and formation of acids during storage. Acidic
gas 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 gas 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
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.
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:
SRelease the throttle trigger.
SMove the ON/STOP switch to the STOP
position.
CUTTING METHODS
WARNING: Use minimum speed and
do not crowd the line when cutting around
hard objects (rock, gravel, fence posts, etc.),
which can damage the trimmer head, become
entangled in the line, or be thrown causing a
serious hazard.
SThe 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.
Tip of the line
does the cutting.
Right Wrong
Line crowded into
work area.
SThe 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.
SFor trimming or scalping, use less than full
throttle to increase line life and decrease head
wear, especially:
SDuring light duty cutting.
SNear objects around which the line can wrap
such as small posts, trees or fence wire.
SFor mowing or sweeping, use full throttle for a
good clean job.
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 con-
tact. Do not force trimmer line into work area.
Trimming
8 cm above
ground
SCALPING -- The scalping technique removes
unwanted vegetation down to the ground. Hold
the bottom of the trimmer head about 3 in. (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 in-
creases line wear.
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.
Mowing
SWEEPING -- The fanning action of the rotat-
ing line can be used to blow away loose debris
from an area. Keep the line parallel to and
above the area surface and swing the tool
from side to side.
Sweeping

OPERATING INSTRUCTIONS FOR
USE WITH WEED BLADE
SBlade 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.
SWHAT 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.
SWHEN 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.
SCut 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.
SKeep the blade sharp. A dull blade is more
likely to snag and thrust.
SCut only at full throttle. The blade will have
maximum cutting power and is less likely to
bind or stall.
S“Feed” the blade deliberately and not too
rapidly. The blade can thrust away if it is fed
too rapidly.
SCut only from your left to your right. Cutting on
right side of the shield will throw debris away
from the operator.
SUse 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.
SKeep feet comfortably spread apart and
braced for a possible sudden, rapid thrust of
unit. Do not overreach. Keep firm footing and
balance.
SKeep blade below waist level; it will be
easier to maintain control of unit.
SDo not raise the engine above your waist as
the blade can come dangerously close to
your body.
SDo 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 blade turns at idle,
do not use your unit. Refer to the CARBURE-
TOR ADJUSTMENT section or contact your
authorized service dealer.
SMaintain good firm footing while using the
unit. Do this by planting feet firmly in a
comfortable apart position.
SCut while swinging the upper part of your
body from left to right.
