6. Cutting equipment
This section describes how through correct maintenance and
through using the right type of cutting equipment you can:
• Reduce the machine's tendency to kickback
• Obtain maximum cutting capacity.
• Increase the service life of the cutting equipment.
Four basic rules:
1)Only use the cutting
and guard equipment
we recommend! See
chapter "Technical
data".
2)Keep the blade's teeth
well and correctly
sharpened! Follow our
instructions and use the
recommended filing
gauge. An incorrectly
sharpened or damaged
blade increases the risk
of an accident.
3)Keep the correct setting.
Follow our instructions
and use the
recommended setting
tool. An incorrectly set
blade increases the risk
of jamming and
kickback.
4)Check the cutting
equipment with regard
to damage and crack
formation. Damaged
cutting equipment
should always be
replaced.

injury when assembling,
use the blade guard as
protection when tightening

turning in the direction of
rotation. (NOTE! the nut

socket spanner, 35 - 50
Nm (3.5 - 5 kpm).
NOTE!
The locking nut's nylon lock
