Prerequisite:
– The machine is disconnected from the tractor.
– The height of the needles on the knotter is checked or set, refer to chapter Settings “Setting
the Height of the Needles on the Knotter”.
– The upper dead point of the needles is checked or set, refer to chapter Settings “Upper
Dead Point of the Needles”.
– Before you perform settings on the needle yoke brake, the needle yoke must be in the idle
position (this means that the crank arm (1) and the needle connecting rod (2) are in the
extended position). It can be recognized by the trigger roller (8) which is in the recess of the
knotter gear.
