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.

Eye Protection
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
The trimmer linewill advance approximately 2
in. (5 cm) each timethe bottom ofthe trimmer
head is tapped on the ground with the engine
running at full throttle.
The most efficient line length is the maximum
length allowed by the line limiter.
Always keep the shield in place when the tool
is being operated.
To advance line:
S Operate the engine at full throttle.
S Holdthe trimmer head parallelto andabove
the grassy area.
S Tap the bottom of the trimmer head lightly on
the ground one time. Approximately 5 cm of
line will be advanced with each tap.
Always tap the trimmer head on a grassy
area. Tapping on surfaces such as concrete
or asphalt can cause excessive wear to the
trimmer head.
If the line is worn down to 5 cm or less, more
than one tap will be required to obtain the
most efficient line length.
WARNING: Use only 2 mm diameter
line. Other sizes andshapes ofline will not advance properly andwill result in improper cutting headfunction orcan 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.
CUTTING METHODS
WARNING: Use minimumspeed and
do not crowd the line when cutting around
hard objects (rock, gravel, fence posts, etc.),
which candamage the trimmer 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 mini-
mum linewear 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
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 Formowing orsweeping, usefull 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.

ground and atan angle. Allow the tipof theline
to strike the ground around trees, posts,
monuments, etc. This technique increases
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.
