7 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 power tool 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 power tool so 
that the wind or operating process directs any dust, 
mist or other particulate matter raised by the power 
tool 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.
7.5.4 Operating Instructions
WARNING
■ In the event of an emergency, switch off the motor 
immediately and remove the connecting cord from the 
KombiMotor.
■ On many KombiTools, the cutting/working attachment or 
tool will continue 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/working attachment or 
tool: 
– Wait for the cutting/working attachment or tool to 
stop before walking with the unit or putting it down.
■ Use of non-approved KombiTools or cutting/working 
attachments could be extremely dangerous.
– Use only the KombiTools and cutting/working 
attachments recommended in this manual. See 
Approved KombiTools, @ 26.
■ To reduce the risk of severe personal injuries from 
unintentional starting: 
– Never touch the KombiTool or its 
cutting/working attachment with your 
hand, feet or any other part of your body 
while the power tool is connected to a 
battery.
