WARNING
The rotating cutting attachment may
fling foreign objects directly or by
ricochet 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. Even maintaining a
minimum distance of 15 meters cannot
exclude the potential danger. 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
Inspect the work area: To
reduce the risk of injury,
remove stones, pieces of
metal and other solid
objects which could be
thrown 15 meters or more
by the cutting attachment
or damage the cutting
attachment and property
(e.g. parked vehicles,
windows).

WARNING
This clearing saw is normally to be used
at ground level with the cutting
attachment parallel to the ground. Use of
a clearing saw above ground level or
with the cutting attachment
perpendicular 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 clearing saw
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 clearing
saw, 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
properly tightened, stop work
immediately. The retaining nut may be
worn or damaged and should be
replaced. If the blade or head continues
to loosen, see your STIHL dealer. Never
use a clearing saw 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
immediately, 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 ricochets in
such situations.
WARNING
If a rotating metal blade strikes a rock or
other hard object, sparks may be
created, which can ignite flammable
materials under certain circumstances.
Flammable materials can include dry
vegetation and brush, particularly when
weather conditions are hot and dry.
When there is a risk of fire or wildfire, do
not use metal blades around flammable
materials or around dry vegetation or
brush. Contact your local fire authorities
or the U.S. Forestry Service if you have
any question about whether vegetation
and weather conditions are suitable for
the use of a metal blade.
