N Use a feeler gauge to measure the
distance between the other teeth
and the gauge rod.
Depending on the type of cutting
attachment, different maximum limits
apply for axial out-of-balance:
Cutting attachment
Grass cutting blade,
Ø 230 mm
Grass cutting blade,
Ø 255 mm
Brush knife, Ø 250 mm 1.0 mm
Brush knife, Ø 300 mm,
Ø 305 mm
Brush knife, Ø 350 mm 2.0 mm
For safety reasons a metal cutting
tool must not be straightened. The
cutting attachment must not be
used if the maximum out-of-
balance limit is exceeded since
there is otherwise a risk of
accidents.
Testing radial out-of-balance
Radial out-of-balance is tested with a
magnetic test weight.
N Use a sharp knife to cut the test
weights along the stamped lines.
The test weight is attached to one blade
tooth at a given distance "R" – see the
Distance
