Trimmer and Brushcutter Safety Manual
English
10
– Avoid contact with stones, rocks,  
pieces of metal and other solid 
foreign objects.
– Never cut wood or shrubs with a 
stem diameter of more than 2 cm – 
use a circular saw blade for this 
purpose.
– Inspect the brush knife at regular 
short intervals for signs of damage. 
Do not continue working with a 
damaged brush knife.
– Resharpen the brush knife regularly 
(when it has dulled noticeably) and 
have it balanced if necessary 
(STIHL recommends a STIHL 
servicing dealer).
Shredder Blade
Suitable for thinning and shredding 
tough, matted grass and scrub.
To cut wild growth and scrub, lower the 
shredder blade down onto the growth to 
achieve shredding effect – do not use 
the cutting attachment above waist 
height.
Exercise extreme caution when using 
this method of cutting. The higher the 
cutting attachment is off the ground, the 
greater the risk of injury from cuttings 
being thrown sideways.
Warning! Improper use may damage the 
shredder blade – risk of injury from 
thrown parts.
To reduce the risk of injury it is essential 
to take the following precautions:
– Avoid contact with stones, rocks,  
pieces of metal and other solid 
foreign objects.
– Never cut wood or shrubs with a 
stem diameter of more than 2 cm.
– Inspect the shredder blade at 
regular short intervals for signs of 
damage. Do not continue working 
with a damaged shredder blade.
– Resharpen the shredder blade 
when it has dulled noticeably and 
have it balanced if necessary (by 
servicing dealer).
Circular Saw Blade
For cutting shrubs and trees:
Up to a stem diameter of 4 cm when 
used on brushcutters.
Up to a stem diameter of 7 cm when 
used on clearing saws.
Before starting the cut, accelerate the 
engine up to full throttle. Perform cut 
with uniform pressure.
Use circular saw blades only with a 
matching limit stop of the correct 
diameter.
When felling, maintain a distance of at 
least two tree lengths from the next 
felling site.
Risk of kickout
The risk of kickout is highest in the black 
area of the blade: Do not use this area of 
the circular saw blade for cutting.
There is also a risk of kickout when 
using the lighter shaded areas of the 
blade: These areas of the blade should 
only be used by experienced operators 
with specialized training.
STIHL recommends that you use the 
non-shaded area of the circular saw 
blade. Always start the cut with this area 
of the blade.
To reduce the risk of blade 
damage, avoid contact with 
stones and the ground. 
Resharpen the blade properly in 
good time – dull teeth may result 
in the blade cracking and 
shattering and causing serious 
injury.
