Husqvarna K750 Manual: Assembly and Maintenance Instructions

ASSEMBLY

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.

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 shaft can be locked using a screwdriver, steel pin or the like. This is slid in as far as possible. The blade is tightened clockwise.

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.

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.
