!Warning!
It is essential to determine the exact 
direction of the cut before applying the 
abrasive wheel to the work. Wheels are 
constructed for radial pressure only. 
Lateral pressure must be avoided. Hold 
the cut-off machine steady. To reduce 
the risk of serious or fatal injury, do not 
change the direction of the cut during the 
cut as this may produce a high torsional 
load on the abrasive wheel and may 
cause it to break or shatter.
!Warning!
Do not use abrasive wheels for rough 
grinding. Large bending stresses occur 
during such work and abrasive wheels 
may shatter or break and could cause 
serious or fatal injury.
!Warning!
To reduce the risk of injury from 
shattered abrasive wheels:
1. Do not exceed the maximum 
operating speed marked on the 
wheel.
2. Do not use a wheel that has been 
dropped. 
3. Test each new wheel immediately 
after installation for approximately 
one minute at maximum speed 
without cutting, making sure to keep 
bystanders away.
4. Do not cut any material for which the 
abrasive wheel is not authorized.
5. Do not grind on the side of the 
abrasive wheel.
6. Do not twist, thrust, knock or drop 
the machine. This can cause 
damage to the wheel. 
To achieve a clean and efficient cut, pull 
the abrasive wheel across the work or 
move it "to and fro" in the cutting 
direction. Do not use force to push the 
abrasive wheel into the work.
Insert the wheel into the material only as 
deep as necessary to make the cut. To 
reduce the amount of dust created, do 
not cut all the way through stone and 
concrete materials - leave a thin piece 
uncut. For most such materials, this 
piece can be easily broken afterwards. 
Do not cock, jam or wedge the wheel in 
the cut.
Always stop the engine and be sure the 
wheel has stopped rotating before 
setting down the cut-off machine.
If a cut-off machine cart is used, sweep 
debris from the path of the wheels, as 
debris under one of the cart’s wheels 
may cause flexing of the abrasive wheel. 
This could result in high frictional forces 
and thus greatly reduce the engine 
power available for the actual cutting 
work. It could also damage the abrasive 
wheel.
STIHL recommends the use of the cart 
for longer cuts in a straight line.
Wet Cutting with Abrasive Wheels
Before wet cutting, make sure water will 
not damage the floor or building.
!Warning!
To reduce the risk of electrocution to you 
or bystanders, do not allow water or 
sludge to contact live electric wires.
!Warning!
To reduce the risk of injury from wheel 
breakage when wet cutting with a 
composite non-diamond wheel:
1. Never store and re-use a wheel that 
has been used with water. Use 
these wheels up the same day.
