General

WARNING! The engine should be
!
switched off, and the stop switch in
STOP position.
Husqvarna's blades are high speed blades approved for
hand held power cutters.
Checking the spindle shaft and
flange washers
When the blade is replaced with a new one, check the
flange washers and the spindle shaft.
• Check that the threads on the spindle 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
spindle shaft.
Do not use warped, notched, indented or dirty flange
washers. Do not use different dimensions of flange
washers.

Checking the arbor bushing

The arbor bushings are used to fit the machine to the
centre hole in the cutting blade. The machine is supplied
with either a bushing that can be flipped over to fit blades
with either 20 mm or 1" (25,4 mm) centre holes, or with an
fixed 20 mm bushing. A decal on the blade guard
indicates which bushing has been factory fitted together
with 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.

ASSEMBLING AND ADJUSTMENTS

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.
