Removing The Cassette Unit
To remove the cassette unit for maintenance or to exchange cassettes the following
procedure should be followed:-
1) Unscrew the hand wheel of the retaining pin for about half-an-inch (13mm) until the
pip end is inside the nut on the side frame.
2) Slide the cassette unit along the tie bars as far as it will go until the cutter nut and
coupling is clear of the three pins in the driving coupling.
3) Remove the unit from the chassis by lifting in a swinging motion from the back.
To replace the cassette unit :-
1) Place the front slots of the cassette unit frames on the two front retaining pins seen
projecting from inside each frame.
2) Carefully lower the unit in a downward swinging motion until the rear slots of the
cassette unit frame rest on the cross tie bar.
3) Move in a lateral direction away from the retaining pin until the three holes of the
cassette nut and coupling are in full engagement with the three pins of the driving
coupling.
4) Screw up the hand wheel with the retaining pin, engaging the hole in the side frame
on the opposite side. Do not over tighten.
