Husqvarna’s blades are approved for hand-held power 
cutters. Blades are manufactured with three different 
diameters of centre holes: 20 mm (0.787"), 22.2 mm (7/8") 
and 25.4 mm (1"). 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.

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

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

The cutting blade/axle can be locked by holding in the locking 
button on the rear of the machine. The button is spring-loaded 
and is reset when button is released.

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.

There is an arrow on the rear of the machine that indicates the 
axles direction of rotation that the disc is mounted on.

When the blade is replaced with a new one, check the flange 
washers and the drive axle. See instructions under the 
heading Checking the drive axle and flange washers.

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.

The guard must always be fitted on the machine.

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.
