Fitting the cutting blade
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 machine that indicates the axleís
direction of rotation that the blade 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.
Checking the drive shaft 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.
Guard for the blade
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.

WARNING! Always pull out the plug from
the outlet socket before cleaning,
maintenance or assembly.
