brand synthetic oil. Mix gasoline and oil
at a ratio of 40:1. A 40:1 ratio is
obtained by mixing 3.2 ounces of oil
with 1 gallon of unleaded gasoline=
Included with this trimmer is a 3.2
ounce container of oil. Pour the entire
contents of this container into 1 gallon
of gasoline to achieve the proper fuel
mixture. DO NOT USE automotive oil or
marine oil. These oils will cause engine

4_WARNING: Always wear eye
protection. Always use hearing 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.
When operating unit, stand as shown
and check for the following:
• Wear eye protection and heavy
clothing.
• Hold trigger handle with right hand
and assist handle with left hand.
• Hold unit so that engine is below
waist level.
• Out only from your left to your right to
ensure debris is thrown away from
you. Without bending over, keep line
near and parallel to the ground and
not crowded into material being cut.
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.
HOW TO STOP YOUR UNIT
• Release the throttle trigger.
• Push and release the engine ON/
STOP switch.
TRIMMER LINE ADVANCE
The trimmer line will advance approxi-
mately 2 inches (5 cm) each time the
bottom of the 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:
• Operate the engine at full throttle.
• Hold the trimmer head parallel to
and above the grassy area.
• Tap the bottom of the trimmer head
lightly on the ground one time. Ap-
proximately 2 inches (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 ex-
cessive wear to the trimmer head.
If the line is worn down to 2 inches (5
cm) or less, more than one tap will be
required to obtain the most efficient line
length.
_I=WARNING: Use only 0.095 inch
(2.4 ram) diameter line. Other sizes of
line will not advance properly and will
result in improper cutting head func-
tion 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 danger-
ous missile that can cause serious in-
jury.
CUTTING METHODS
A_,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.
• The tip of the line does the cutting.
You will achieve the best perform-
ance 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 Line crowded into
does the cutting, work area,
Right Wrong
• 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.
• For trimming or scalping, use less
than full throttle to increase line life
and decrease head wear, especially:
• During light duty cutting.
• Near objects around which the line
can wrap such as small posts,
trees or fence wire.
• For mowing or sweeping, use full
throttle for a good clean job.
TRIMMING - Hold the bottom of the
trimmer head about 3 inches (8 cm)
above the ground and at an angle. Al-
low only the tip of the line to make
contact with vegetation. Do not force
trimmer line into work area.

SCALPING - The scalping technique
removes unwanted vegetation down
to the ground. Hold the bottom of the
trimmer head about 3 inches (8 cm)
above the ground and at an angle. Al-
low the tip of the line to strike the
ground around trees, posts, monu-
ments, 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.

SWEEPING - The fanning action of the
rotating 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.
