Checking the drive shaft and flange washers

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.

Checking the bushing

Bushings are used to fit the machine to the centre hole in the cutting blade. The machine is supplied with a bushing that can be flipped over to fit either 20 mm or 1” (25.4 mm). A decal on the blade guard indicates appropriate blade specification.

Check that the bushing on the machine's spindle shaft corresponds with the centre hole of the cutting blade. The blades are marked with the diameter of the centre hole.

Use only bushings supplied by Husqvarna. Those bushings have been designed for your power cutter.

Checking the direction of the blade rotation

When using diamond blades make sure that it rotates in the direction indicated by the arrow on the blade. The direction of rotation for the machine is shown by arrows on the cutting arm.

Fitting the cutting 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. Insert a tool in the hole in the cutting head and rotate the blade until it is locked.

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

Blade guard

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 blade guard is friction locked.

Press the ends of the guard against the work piece or adjust the guard with the adjustment handle. The guard must always be fitted on the machine.
