Drive Belt - Husqvarna K760 Cut-n-Break Manuel D'utilisation

• 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! 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.
• Tighten the drive belt. See instructions under the
heading "Drive belt".
