Warning! The drive dogs on the machine spindle and blade flange bust be completely in
mesh before the clamping screw is tightened to prevent damage to the coupling. Failure to
follow this instruction may result in coupling overload and a failure can lead to serious
personal injury or death.
How to fit a blade on a standard blade flange:
Centre bore:
The saw blade should have a hole with diameter 60 mm –0 +0.1 mm,
and be free from cracks, dents, burrs and dirt.
Transmission of
torque:
The friction surfaces of both the flange and the blade must be free from
grease and dirt to be able to securely transmit the torque of the saw
blade motor without slippage. Slippage will cause irreparable damage to
the flanges.
Clamping:
The blade is fitted on the inner flange and is clamped by the outer collar
with a special centre bolt. Grease the centre bolt and thread regularly.
The centre screw should be tightened to 60-70 Nm for the version with
two friction surfaces and 40 Nm for the version with one friction surface,
see picture below for difference. Don’t mix the different versions.
The blade and flange are now ready to be fitted on to the machine
spindle with the quick coupling, see “Mounting the blade with flange on
the machine spindle”.
Warning! The bolt or the female thread in the blade flange may never start to corrode.
Corrosion of the threads or any part of the bolt may cause failure of the bolt which can lead
to serious personal injury or death.
Warning! The saw blade must always be fitted correctly and a torque wrench must be used
to tighten the centre bold to the correct Nm, to avoid danger. The instructions given above
must always be followed to avoid faulty mounting of the blade.
Two friction surfaces:
Tighten with torque wrench to 60-70 Nm
Must be kept clean!
One friction surface:
Tighten with torque wrench to 40 Nm
Must be kept clean!
