When the blade is replaced with a new one, check the flange 
washers and the drive shaft.

•

Check that the threads on the drive shaft are undamaged.

•

Check that the contact surfaces on the blade and the 
flange washers are undamaged, of the correct dimension, 
clean, and that they run properly on the drive axle.

•

Do not use warped, notched, indented or dirty flange 
washers. Do not use different dimensions of flange 
washers.

•

Husqvarna’s blades are approved for hand-held power 
cutters.

•

Bushings can be fitted on the machine axle to adjust the 
machine to the centre hole of the blade. Use a bushing 
with the correct diameter! The blades are marked with the 
diameter of the centre hole.

•

When a diamond blade is mounted on the power cutter 
make sure that the diamond blade will rotate in the 
direction indicated by the arrow on the blade.

•

The blade is placed on the bushing (A) between the inner 
flange washer (B) and the flange washer (C). The flange 
washer is turned so that it fits on the axle.

•

Lock the shaft.

•

Tightening torque for the bolt holding the blade is: 15-25 
Nm (130-215 in.lb).

•

The guard for the cutting equipment should be adjusted so 
that the rear section is flush with the work piece. Spatter 
and sparks from the material being cut are then collected 
up by the guard and led away from the user. The guard 
must always be fitted on the machine.
