the outlet socket before cleaning,
maintenance or assembly.
Assembling the blades
• Husqvarna blades are especially manufactured and
approved for freehand cutting with the K 3000 Cut-n-
Break. The blades have integrated belt pulley halves
and are to be changed in pairs.
• Loosen the nuts and clamping bolt which release the
bar. 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".
NOTICE! 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.
• 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. Tightening

torque for the bolt holding the blade is: 15 Nm (130
in.lb).
NOTICE! 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".
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.
