There are two scales that require setting dependant upon the size of the oval/circle:
1.
The width of the oval (or diameter of the circle) is set on the beam scale by
squeezing the release lever and cutter head support then sliding the cutter until
the red line in the window indicates the required dimension. The scale can be
read in inches or centimetres.
Scale
If the measuring scale itself slides too easily set the cutting head to
tightening
10 (cms. or ins.), slide the scale from its groove by about 10cm [4”]
and twist it to lightly distort the strip. Replace the scale and check
the friction, slide the scale to again read 10.
2.
The difference between the width and length of the oval is set on the differential
scale, turn the knob counter-clockwise by half a turn to release and set to the
required dimension, lock in position. For a circle set the pointer as far to the right
as it will go (not necessarily the ‘zero’ on the scale). The scale will be set to either
inches or centimetres and can be changed by turning the scale over as follows:
3.
Set the scale to zero and remove the two screws then remove the knob and
pointer. Turn the scale over and carefully refit the pointer ensuring the small pin is
located in the hole (as shown), refit the knob and loosely refit the two screws.
Adjust the scale so that it reads zero then moderately tighten the two screws.
If you find the machine does not cut accurately the scales require calibrating – refer to
the next section.
