Stihl FB 131 Instruction Manual page 11

WARNING
Inhalation of certain dusts, especially
organic dusts such as mold or pollen,
can cause susceptible persons to have
an allergic or asthmatic reaction.
Substantial or repeated inhalation of
dust and other airborne contaminants, in
particular those with a smaller particle
size, may cause respiratory or other
illnesses. Control dust at the source
where possible. Use good work
practices, such as operating the unit so
that the wind or operating process
directs any dust raised by the power tool
away from the operator. Follow the
recommendations of EPA / OSHA /
NIOSH and occupational and trade
associations with respect to dust
("particulate matter"). When the
inhalation of dust cannot be
substantially controlled, i.e., kept at or
near the ambient (background) level, the
operator and any bystanders should
wear a respirator approved by NIOSH /
MSHA for the type of dust encountered.
Operating Instructions
WARNING
Do not operate your power tool using the
starting throttle lock, as you do not have
control of the engine speed.
In the event of an emergency, switch off
the engine immediately by pressing the
stop switch.
WARNING
The cutting attachment continues to
rotate for a short period after the throttle
trigger is released (flywheel effect.)
FB 131
WARNING
The rotating cutting attachment may
fling foreign objects directly or by
ricochet a great distance.
15 m (50 ft)
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 bed redefiner is normally to be used
at ground level with the blade
perpendicular to the ground. Use of a
bed redefiner above ground level or with
the cutting attachment parallel to the
ground may increase the risk of injury,
since the cutting attachment is more fully
exposed and the bed redefiner may be
more difficult to control.
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 for cracks, wear
and damage.
WARNING
A loose blade may vibrate, crack, break
or come off the bed redefiner, 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
loosens after being properly tightened,
stop work immediately. The retaining nut
may be worn or damaged and should be
replaced. If the blade continues to
loosen, see your STIHL dealer. Never
use a bed redefiner with a loose cutting
attachment.
