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 axle can be locked by inserting a screwdriver or the like in the hole in the belt guard.

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.

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 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.

Cutting arm

It is possible to turn the cutting arm 180° so that the blade comes on the other side of the cutting arm. This simpliﬁes cutting close to obstacles such as walls and ﬂoors etc. The cutting arm and drive belt are released in the same way as when replacing the drive belt. See instructions under the heading Replacing the drive belt.

Turn the arm 180°, replace the respective parts, and screw them secure in the same way as before.

If you are using a diamond blade you must also turn it so that it rotates in the right direction. A diamond blade must rotate in the direction shown by the arrow marking on the blade.

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.
