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 the FSA 130,
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 your FSA model. 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
www.stihlusa.com or contact your authorized STIHL
servicing dealer.

5.8 Working with the Cutting Attachments
5.8.1 Kickout (Blade Thrust) with All Metal Cutting Attachments
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.
￭ 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.
0000-GXX-3025-A1
– Keep metal cutting attachments sharp.
– Keep bystanders at least 50ft. (15m) away from the
work area.
