Assembly

WARNING! Always pull out the plug from

the outlet socket before cleaning,
maintenance or assembly.
Assembling the blades
WARNING! You must replace the screw
!
kit when you replace the blade.
• Husqvarna blades are especially manufactured and
approved for freehand cutting with the K 4000 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.
Place the blades on each side of the bar. Insert the
•
steering pins of the nut through the blades and the
bolt washer.
Rotate the blades by hand while tightening the blade
•
bolt. This is especially important because it assures
the belt is not squeezed between the pulley halves,
which are incorporated into the blades. Alternate
between tightening the blade bolt and rotating the
blades until the blades are fully tightened.
Tighteningtorque for the bolt holding the blade is:
130 in.lb (15 Nm).

Protection for the blades
• The guards should always be fitted on the machine.

before starting to cut.
