automatically when tapped against the
ground.

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

Using the grass cutting blade
All kinds of grass and weeds can be
easily cut with the grass cutting blade.
The brushcutter is swept in an arc
similar to a scythe.
!
Warning!
To reduce the risk of serious or fatal
injury never attempt 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.
The 8-tooth grass cutting blade is
recommended for cutting fern or reed.
Both blades have to be resharpened
when all cutting edges are dull.
Using the brush knife
When fitted to the brushcutter, the brush
knife is suitable for applications ranging
from cutting matted grass to clearing
weeds, wild growth and scrub.
To cut wild growth and scrub, lower the
rotating brush knife down onto the
growth to achieve a chopping effect. Use
the brushcutter like a scythe to cut
grass, i.e. sweep it to and for in an arc.
!
Warning!
When cutting woody materials, use the
left side of the blade to avoid "kickout"
(blade thrust) situations.
!
Warning!
Improper use of a brush knife may cause
it to crack, chip or shatter.
