1 Introduction

1Introduction
Thank you for your purchase. The information contained in
this manual will help you receive maximum performance and
satisfaction from your trimmer and, if followed, reduce the
risk of injury from its use.
The terminology utilized in this manual when referring to the
power tool reflects the type of cutting attachments that may
be mounted on it. The term "trimmer" is used to designate an
FS / FSA unit that is equipped with a nylon line head or a
head with flexible plastic blades (i.e., the PolyCut head.) A
"brushcutter" designates a unit equipped with a rigid metal
blade. Many STIHL FS / FSA models, including this power
tool, may be used as either a trimmer or a brushcutter.
Therefore, the power tool is referred in this manual as a
"trimmer / brushcutter."
SAVE THIS MANUAL!
Because a trimmer / brushcutter is a high-speed
cutting tool, special safety precautions must be
observed to reduce the risk of personal injury.
Read this instruction manual thoroughly before
use and periodically thereafter. Follow all safety
precautions. Careless or improper use can
cause serious or fatal injury.
WARNING
As more fully explained later in this manual, to reduce the
risk of personal injury, make sure your unit is equipped with
the proper handle, harness and deflector for the type of
cutting attachment you are using. Use only cutting
attachments that are specifically authorized by STIHL for
use with this power tool. Always wear proper protective
apparel and eye protection. Bystanders, especially children,
and animals should not be allowed in the work area where
the trimmer is in use.
WARNING
Use of this machine may be hazardous. If the rotating line or
blade comes in contact with your body, it will cut you. When
it comes in contact with solid foreign objects such as rocks,
glass or bits of metal, it may fling them directly or by ricochet
in the direction of bystanders or the operator. Striking such
objects could damage the cutting attachment and may
cause blades to crack, chip or break. Thrown objects,
including broken heads or blades, may result in serious or
fatal injury to the operator or bystanders. Follow the safety
precautions in this manual to reduce the risk of personal
injury.
2 Guide to Using this Manual
Have your authorized STIHL servicing dealer show you how
to operate your power tool.
Do not lend or rent the power tool without this instruction
manual. Allow only persons who fully understand the
information in this manual to operate the trimmer /
brushcutter.
For further information, or if you do not understand any of
the instructions in this manual, please go to

0458-662-8621-A
17
English
0000-GXX-3800-A0
5 IMPORTANT SAFETY INSTRUCTIONS
WARNING
Kickout (blade thrust) is the sudden and
uncontrolled movement of the cutting head
toward the operator's right or rear that can occur
when the shaded areas (especially the darkly
shaded area) of a rotating blade contact a solid
rigid object like a tree, rock, bush or wall. The
cutting attachment may be thrown to the right or
to the rear (black arrow) any time the rapid
rotation of the blade is stopped, slowed,
snagged or bound in an object that it doesn't
immediately cut.
￭ This kickout (blade thrust) may cause loss of control and
may result in serious or fatal injury to the operator or
bystanders. To reduce the risk of injury, extreme caution
should be used when cutting with the shaded area of any
rigid blade (see illustration).
￭ The greater the force of the kickout reaction, the more
difficult it becomes for the operator to control the unit.
Blade thrust is more likely to occur in areas where it is
difficult to see the material being cut.
￭ Many factors influence the occurrence and force of the
kickout reaction. These include cutting attachment speed,
the speed at which the cutting attachment contacts the
object, the location and angle of contact, the condition of
the cutting attachment, and how quickly the cutting
attachment is slowed, snagged or stopped, among other
factors.
– Use caution when working with the shaded areas of
any metal cutting attachment.
￭ To reduce the risk of personal injury from kickout and
blade thrust when using a rigid cutting attachment:
– Avoid cutting close to fences, sides of buildings, tree
trunks or other such objects when a metal cutting
blade is mounted. STIHL recommends using a nylon
line head for such jobs.
– Keep metal cutting attachments sharp.
– Keep bystanders at least 50 ft. (15 m) away from the
work area.
5.8.2 Using a Mowing Head
► When working, sweep the trimmer in a controlled manner,
parallel to the ground in front of you.
Mowing heads are to be used only on units equipped with a
line-limiting blade in the deflector in order to keep the line at
the proper length. When trimming along a fence, wall or
around trees, it is preferable to use a mowing head with
nylon line to reduce the risk of blade thrust or kickout,
damage to the cutting attachment, and to reduce damage to
the fence, wall or trees.
WARNING
￭ To reduce the risk of serious injury:
– Never use wire or metal-reinforced line or other
material in place of the recommended nylon cutting
line. Pieces of wire could break off and be thrown at
high speed toward the operator or bystanders.
￭ A cracked, damaged or worn out mowing head may
shatter at high speeds and cause serious or fatal injury.
– Have a cracked, damaged or worn out mowing head
replaced immediately, even if damage appears to be
limited to superficial cracks.
￭ When working close to fences, sides of buildings, tree
trunks of other such objects, be alert to an increased
possibility of ricochets.

English
– Take care to clear area of all objects and
debris before trimming along fences or
walls, near tree trunks or other objects
that could increase the possibility of
injury from the ricochet of thrown objects.
5.8.3 Using a Grass Cutting Blade
► When working with a grass cutting blade, sweep the
trimmer in a controlled manner, parallel to the ground in
front of you. To reduce the risk of kickout, use the left side
of the cutting blade.
All kinds of grass and weeds can be cut with a grass cutting
blade.
– The 4-tooth grass cutting blade is intended to cut grass
and weeds. It has 4 cutting knives with cutting edges on
both sides, i.e., front and rear. When the cutting edges on
one side become dull, the blade can be turned over to
utilize the cutting edges on the other side before it is
resharpened.
– The 8-tooth grass cutting blade is recommended for
cutting fern or similar fleshy vegetation. When the cutting
edges on one side become dull, the cutting edges have to
be resharpened. The blade cannot be turned over to
utilize the cutting edges on the other side.
WARNING
￭ Improper use of a grass cutting blade may cause it to
crack, chip or shatter. Thrown blade fragments may
seriously or fatally injure the operator or bystanders. To
reduce the risk of injury:
– Avoid contact with hard or solid foreign objects such
as stones, glass, rocks or pieces of metal.
– Inspect the grass cutting blade at regular, short
intervals for signs of damage. Do not continue
working with a damaged grass cutting blade.
– Resharpen the grass cutting blade regularly as
described on its packaging or instruction leaflet.
– Never attempt to cut woody material with the grass
cutting blade.
5.8.4 Using a Brush Knife
