7.2 Changing the main saw blade
The following basic points should be noted:
– Do not fit any saw blades that have cracks or
are damaged in any other way.
– Only fit saw blades with a diameter of between
250 and 400 mm
– Check that the speed set for the saw blade is
not too high. For composite saw blades the
highest permitted speed is shown on the blade
in the formn =... .
max
Please note that only saw blades with adjacent
holes (2 holes 10 mm ø spaced at 60 mm) can be
tensioned. This is necessary to prevent the saw
blade securing system becoming loose during
braking..
Warning!
Check saw blade retaining disc for tightness
before operating machine!
