WARNING
Three rectangular wear limit marks are 
applied to the base (periphery) of the 
PolyCut. To reduce the risk of serious 
injury from breakage of the head or 
blades, the PolyCut must not be used 
when it has worn as far as one of these 
marks. It is important to follow the 
maintenance instructions supplied with 
the head.
STIHL FixCut mowing head
Uses pre-cut lengths of nylon line.
Observe wear indicators.
Do not continue using the mowing head 
if the raised moldings (1) on the base 
are missing or worn – see right 
illustration above. The mowing head 
may otherwise shatter and flying objects 
could result in injury to the operator or 
bystanders. Install a new mowing head.
Risk of Kickout (Blade Thrust) with all 
Rigid Cutting Blades
WARNING
This kickout (blade thrust) may cause 
loss of control of the power tool and may 
result in serious or fatal injury to the 
operator or bystanders. To reduce the 
risk of injury, extreme caution should be 
used when cutting with the shaded area 
of any rigid blade.
Using the Grass Cutting Blade
All kinds of grass and weeds can be 
easily cut with the grass cutting blade. 
The power tool is swept in an arc similar 
to a scythe.
WARNING
To reduce the risk of serious or fatal 
injury from blade breakage, never 
attempt to use this blade to cut woody 
materials.
The 4-tooth grass cutting blade is 
intended to cut grass and weeds. It has 
4 cutting knives with cutting edges on 
both sides, i.e. front and rear. When the 
cutting edges on one side become dull, 
the blade can be turned over to utilize 
the cutting edges on the other side.
The 8-tooth grass cutting blade is 
recommended for cutting fern or reed.
Both types of grass cutting blade have to 
be resharpened when all cutting edges 
are dull.
Using the Brush Knife
When fitted to the power tool, the brush 
knife is suitable for applications ranging 
from cutting matted grass to clearing 
weeds, wild growth and scrub.
