ASSEMBLY
Assembling the blades
Husqvarna blades are especially manufactured and approved
for freehand cutting with the K650 Cut-n-Break. The blades
have integrated belt pulley halves and are to be changed in
pairs.
• Loosen the bar nuts, unscrew the clamping screw
anticlockwise a few turns and then refit the bar as far as it
will go before you dismantle the old blades. This will
position the drive belt in a more favourable position with
regard to assembling the new blades. The drive belt is
not clamped so easily.
• Dismantle the old blades by loosening the centre nut.
Check the drive belt for wear when the blades are
dismantled. When changing the drive belt see the
instructions under the heading ”Replacing the drive belt”.
• Position the blades on each side of the cutting arm. Make
sure that the holes for both guide pins in the drive belt
halves are aligned so that they correspond with the holes
in the washer, and the nut too. Now fit the bolt and washer
unit with guide pins.
Protection for the blades
• The guards should always be fitted on the machine.
Check that the guards are properly secured and work
before starting to cut.
CAUTION! It is very important that the blades rotate when
the nut is tightened. This is to ensure that the belt is not
clamped between the integrated drive belt halves on the
blades when the blades/drive belt are pulled together with
the nut. Ideally this is done alternately, i.e. tighten a little,
rotate a little and repeat until the blades are secured.
IMPORTANT! Do not forget to tighten the belt and check the
belt adjustment before cutting. See the instructions under
the heading ”Inspecting and adjusting the drive belt”.
