English 5 IMPORTANT SAFETY INSTRUCTIONS
￭ 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. Forest
Service if you have any question about whether
vegetation and weather conditions are suitable for
the use of a metal blade.
– STIHL does not recommend the use of metal blades
when cutting in rocky areas or in areas with debris or
other objects that could create sparks.
￭ Use of this trimmer / brushcutter can generate dust and
other substances containing chemicals known to cause
respiratory problems, cancer, birth defects and other
reproductive harm.
– Consult governmental agencies such as EPA,
OSHA, CARB and NIOSH and other authoritative
sources on hazardous materials if you are unfamiliar
with the risks associated with the particular
substances you are cutting or with which you are
working.
￭ 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 or other airborne contaminants,
especially those with a smaller particle size, may cause
respiratory or other illnesses.
– Control dust at the source where possible.
– To the extent possible, operate the trimmer /
brushcutter so that the wind or operating process
directs any dust, mist or other particulate matter
raised by the trimmer / brushcutter away from the
operator.
– When respirable dust or other particulate matter
cannot be kept at or near background levels, always
wear a respirator that is approved by NIOSH and
rated for worksite-specific conditions. Follow the
recommendations of governmental authorities (e.g.,
OSHA/NIOSH) and occupational and trade
associations.
￭ If the vegetation being cut or the surrounding ground is
coated with a chemical substance, such as a pesticide or
herbicide:
– Read and follow the instructions and warnings that
accompanied the substance coating the vegetation
or surrounding ground.
5.7.4 Operating Instructions
WARNING
￭ In the event of an emergency, switch off the motor
immediately and remove the connecting cord from the
trimmer / brushcutter.
￭ The cutting attachment continues to rotate for a short
period after the trigger switch is fully released. This is
known as the "flywheel effect." To reduce the risk of
serious personal injury from contact with the cutting
attachment:
￭ The rotating cutting attachment may fling foreign objects
directly or by ricochet a great distance. Thrown objects,
including broken cutting attachments, may cause serious
or fatal injury to the operator or bystanders. To reduce the
risk of severe personal injury:
– Wait for the cutting attachment to stop
before walking with the unit or putting it
down.
