During operation
If there is imminent danger or in an 
emergency, immediately stop the 
engine – set the slide control / master 
lever /stop switch to STOPor0.
Check for correct idling so that the 
abrasive wheel is no longer driven when 
the throttle trigger is released and 
comes to a complete halt.
Check and/or correct the idle setting 
regularly. Have the machine repaired by 
a STIHL servicing dealer if the cutting 
wheel continues to turn nevertheless.
Keep the working area clear – bear in 
mind obstacles, holes and pits.
Take care on ice, water, snow, on slopes 
or uneven ground, etc. – risk of slipping!
Do not work while standing on a ladder – 
or in unstable places – not above your 
shoulder height – not with one hand only 
– risk of accident!
Ensure you always have a firm and 
secure footing.
Never work alone – always stay in 
earshot of other persons who can help in 
an emergency.
Keep everyone else away from the 
working area – maintain a sufficient 
distance from other people to protect 
them from noise and flying objects.
Pay increased attention and take 
greater care when wearing ear 
defenders – the perception of sounds 
indicating potential danger (shouts, 
audible warnings, etc.) is restricted.
Take a break before it is too late.
Work calmly and carefully – in daylight 
conditions and only when visibility is 
good. Work with particular care, do not 
endanger others.
Ensure proper ventilation when working 
in trenches, hollows or similar locations 
– risk of fatal injury from breathing toxic 
fumes!
Stop working immediately if you feel 
sick, have a headache, distorted vision 
(for example, shrinking field of vision), 
hearing impairment, dizziness, fading 
powers of concentration – such 
symptoms may be caused, among other 
things, by excessive exhaust 
concentrations – risk of accident!
No smoking when working with or near 
the machine - risk of fire!
If the power tool has been exposed to 
stress due to improper use (e.g. forceful 
impact by striking or dropping), inspect 
the machine to make sure it is in full 
working order before continuing work, in 
every case – see also "Before start-up". 
Check the fuel system for leaks and 
make sure the safety devices are 
working properly. Do not continue 
operating a machine which is damaged. 
In case of doubt, have the unit checked 
by your servicing dealer.
Do not work with the throttle trigger in 
the starting throttle position – in that 
position of the throttle trigger, the engine 
speed cannot be controlled.
Never touch a rotating abrasive wheel 
with your hand or any other part of your 
body.
Check the work area. Avoid danger due 
to damage to pipes and electric power 
lines.
The machine must not be used in the 
vicinity of flammable substances and 
combustible gases.
Do not cut into pipes, metal tanks or 
other containers unless you are 
absolutely sure that they do not contain 
any volatile or flammable substances.
Never leave the machine unattended 
with the engine running. Stop the engine 
before leaving the machine unattended 
(e.g. for breaks).
Before putting the cut-off machine down 
on the ground:
– Switch off the engine
– Wait until the abrasive wheel has 
come to a standstill or brake the 
abrasive wheel until it comes to a 
standstill by carefully touching a 
hard surface (e.g., concrete slab)
Your power tool produces 
toxic exhaust fumes as 
soon as the engine starts 
running. These gases 
may be colorless and 
odorless and may contain 
unburnt hydrocarbons 
and benzene. Never use 
the machine indoors or in 
poorly ventilated areas – 
even if your model is 
equipped with a catalytic 
converter.
