Fitting the cutting head

Fitting the cutting blade

Remove the bolt (1) and nut

(2). Remove the cover. Fit the drive belt over the clutch drum. Refit the cover and tighten the bolt (1) and nut (2).

Feed the drive belt over the pulley on the cutting head.

Secure the cutting head together with the belt guard. Tighten both bolts slightly, then loosen 1/2 turn.

Screw in the tensioning screw

(3)so that the square nut is in line with the arrow on the belt guard. Shake the head to ensure the spring can tension the belt. This automatically adjusts the belt to the correct tension. Tighten both bolts (4) using the combination spanner.

NOTE!

After fitting a new belt the belt tension must be readjusted after the first two tanks of fuel have been used.

Husqvarna cutting blades are manufactured and approved for freehand cutting. The paper labels on each side of the blade are there to distribute the pressure from the flange washer and prevent the blade from slipping.

The blade is placed between the flange hub (A) and the flange washer (B). The flange washer is turned so that it fits in the flange hub. The cutting blade is tightened using the socket spanner 501 69 17-02.

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

Tightening torque for the bolt holding the blade is:

15-25 Nm (130-215 in.lb).

Blade guard

The blade guard should always be fitted on the power cutter.

The guard should be adjusted so that the rear section is close to the work piece. Cutting fragments and sparks are then collected by the guard and led away from the user. By using the lever (A) the guard can be loosened and set in the required position.

Checking the drive shaft and flanges

Check that the threads on the drive shaft are undamaged.

• Check that the contact surfaces of the cutting blade and flanges are flat, run correctly on the spindle and are free from foreign objects.

Do not use flanges that are twisted, have damaged edges, untrue or dirty. Do not use different size flanges.

!WARNING!

16 inch blade and blade guard should only be used on power cutters originally equipped with a 16" blade guard. If a blade guard is fitted as a spare part on a power cutter originally equipped with a 12" or 14" blade guard, the 16" cutting blade will rotate too fast. A cutting blade with too high speed can burst or cause serious injury and damage.
