Blade/Cut Adjustment Procedure

Before commencing any blade adjustments it is very important that the cutting units are
thoroughly cleaned and dry.
To check that the blades are cutting
correctly use a strip of paper as shown.
With the strip of paper held square to
the bottom blade, rotate the cutting
cylinder and see if the blades will cut
the paper. Check this on both ends of
the blades. Never rotate the cutting
cylinder using your hands as the blades
are very sharp and can cause serious
injury. Use a short length of wooden
pole to rotate the cylinder.
If the paper is not cut you will need to
move the bottom blade towards the
cutting cylinder.
To do this, rotate the bottom blade
adjusting nut anti clockwise as shown.
There are two adjuster nuts, one on each
side of the machine. Initially make sure
that you adjust both of them by the same
amount at the same time in order to keep
the bottom blade parallel to the cylinder.
Only ever adjust them by small amounts
at any time.
Check the cut again by using a strip of
paper as previously explained. Once
again please remember to never put your
hand into the cutting cylinder.
If the paper is still not cut correctly,
repeat the above process of adjustment
until the paper is cut.
If one side cuts paper but the other side
does not, then adjust the side that is not
cutting a little bit more until it does cut.
Then check the other side again as this
could now be too tight. Keep adjusting
both sides until the paper is cut across the
entire length of the bottom blade.

Please note that Baroness blades are designed to run non-contact and so do not over
tighten them.
If you are unable to achieve an acceptable cut with just a light contact after performing
the above adjustments then the blades have become a little blunt and so will need back-
lapping.
NOTE: If when you turn the blade adjustment nut the bottom blade does not move and
the adjustment nut just comes loose, then there is a good chance that the bottom blade
pivot pins have seized, thus not allowing the bottom blade to rotate on these pivot pins.
If this happens you will need to refer the machine to your workshop in order to have this
area freed off and lubricated.
Once the blades are cutting paper on both
sides you need to check that you do not
have excessive blade contact.
To do this you need to use another strip of
paper but this time hold it flat along the
surface of the bottom blade as shown.
When you rotate the cutting cylinder the
paper should not be cut but should just
leave an indentation line. If it does this it
is set ok. If it cuts the paper then the
contact is too great and the blades will
need adjusting to provide a slightly less
contact. This is done by turning the blade
adjuster nut clockwise by a small amount.
Only adjust the side which is too tight. If
both sides are too tight then adjust them
both but remember to only use small
adjustments and to keep checking both
sides.
The blades are correctly adjusted when
both sides cut paper when it is held
square to the bottom blade but only
leaves an indentation in the paper when it
is held flat.
