Tractive Support 

 

Screw quality and  
torqueing of screws: 

The blade must be clamped with countersunk screws from Unbrako and 
be of quality 10.9. The nuts must be of type “Nyloc” and the fasteners 
must be torqued with a torque wrench to 35 Nm for M8 screws and to 50 
Nm for M10 and 3/8” screws. The threads must be lubricated with grease 
or oil. 

 

 

Warning! 

The saw blade must always be fitted correctly to avoid danger. The instructions given 

above must always be followed to avoid faulty mounting of the blade, which in turn can cause 
serious personal injury or death. 

 

Warning! 

It  is  important  to  be  aware  of  the  fact  that  when  a  flush  cutting  blade  is  used,  the 

blade is clamped merely by the six countersunk screws, nothing else.

 

 

Warning! 

Flush cutting is a questionable method from a safety point of view. As flush cutting 

requires use of a “half” blade guard, the operator should be aware that the level of safety never 
can be comparable to normal cutting when a full blade 

guard 

is used. This is a potentially 

dangerous method and should be treated likewise.

 

 
Important! 

The blade must have a bolt circle where the holes are spaced on an even and exact 

pitch to prevent unequal load distribution on the screws, blade and flange. Look out for cracks 
around  the  counter  sunk  holes  in  the  blade.  Some  blades  are  prone  to  crack  and  if  that 
happens, it is potentially a very dangerous situation which can lead to fatal accidents. 

 
Mounting the blade  
with flange on the  
machine spindle: 

If  the  procedure  described  above  is  followed,  the  blade  and  flange  are  now 
ready to be fitted on to the machine spindle with the quick coupling. The blade 
flange  is  provided  with  a  radial  T-slot  to  the  centre  of  the  flange.  On  the 
opposite  side  of  the  T-slot,  there  is  a  groove  and  this  groove  should  be 
positioned  upwards  when  the  blade  flange  is  mounted  on  the  saw  head 
spindle.  
 
Use  a  ½”  ratchet  to  tighten  the  clamp  bolt  on  the  rear  side  of  the  spindle. 
Tighten  to  about  30  Nm. 

Do  not  overtighten  the  coupling  clamp  screw!

 

Over  tightening  the  clamp  screw  may  cause  irreparable  damage  to  the 
coupling and flange. 
 

Warning! 

Always keep all part of the coupling clean! The safe operation of the 

coupling depends on cleanliness of all coupling parts on the machine, and the 
blade flange!
