Warning!
The cutting attachment
continues to rotate for a
short period after the
throttle trigger is released
(flywheel effect).
Warning!
The rotating cutting attachment may
fling foreign objects directly or by rico-
chet a great distance.
15m (50ft)
To reduce the risk of eye and other injury
always wear proper eye protection (see
the chapter on "Proper Clothing") and
ensure that bystanders are at least
50 feet (15 m) away. To reduce the risk
of damage to property, also maintain this
distance from such objects as vehicles
or windows. Any coworkers who must be
in the restricted area should also wear
goggles or protective glasses. Stop the
engine immediately if you are
approached.
Warning!
Before you start work,
examine the area for
stones, glass, fence wire,
metal, trash or other solid
objects. The cutting
attachment could throw
objects of this kind.

Warning!
This trimmer / brushcutter is normally to
be used at ground level with the cutting
attachment parallel to the ground. Use
of a trimmer / brushcutter above ground
level or with the cutting attachment per-
pendicular to the ground may increase
the risk of injury, since the cutting
attachment is more fully exposed and
the power tool may be more difficult to
control. Never use your trimmer / brush-
cutter as a hedge trimmer.
Warning!
During cutting, check the tightness and
the condition of the cutting attachment
at regular short intervals with the engine
and attachment stopped. If the behavior
of the attachment changes during use,
stop the engine immediately, wait until
the cutting attachment stops, and check
the nut securing the attachment for
tightness and the blade or head for
cracks, wear and damage.
Warning!
A loose blade or head may vibrate,
crack, break or come off the trimmer /
brushcutter, which may result in serious
or fatal injury. Make sure that the cutting
attachment is properly tightened. Use
the wrench supplied or one of sufficient
length to obtain the proper torque. If the
blade or head loosens after being prop-
erly tightened, stop work immediately.
The retaining nut may be worn or dam-
aged and should be replaced. If the
blade or head continues to loosen, see
your STIHL dealer. Never use a trimmer
/ brushcutter with a loose cutting
attachment.
Warning!
Replace a cracked, damaged or worn-
out head or a cracked, bent, warped,
damaged, dull or worn out blade imme-
diately, even if damage is limited to
superficial cracks. Such attachments
may shatter at high speed and cause
serious or fatal injury.
Warning!
When using rigid blades, avoid cutting
close to fences, sides of buildings, tree
trunks, stones or other such objects that
could cause the power tool to kick out or
could cause damage to the blade.
STIHL recommends use of the nylon
line heads for such jobs. In addition, be
alert to an increased possibility of rico-
chets in such situations.
