Section 3h - Upper blade adjustments (continued)
12. Loosen the grub screw holding the blade guide eccentric on the far left (outer side) of the
blade guide. (Fig.17) Then insert a bar through the blade guide eccentric and then rotate it
towards the front of the machine. (Fig. 18) This will open the gap between the upper and
lower cross cut blades at the narrow end of the blade, (Fig. 19) this is where using a torch
helps; rotate the blade guide eccentric towards the rear of the machine until the light from
the torch is extinguished
.
13. Once you are satisfied this has been set correctly, push on the back of the eccentric (located
inside the machine)
and tighten the grub screw to hold the eccentric in place. (Fig. 17)
14. To adjust the wide end of the blade, firstly make sure that the blade is still positioned as
shown. (Fig. 14)
15. Loosen the grub screw holding the blade guide eccentric on the far right (operator side) of
the blade guide. (Fig. 20) Then insert a bar through the blade guide eccentric and then rotate
it towards the front of the machine. (Fig. 21) This will open the gap between the upper and
lower cross cut blades at the wide end of the blade. You now need to insert an feeler gauge
set to 0.3mm for standard set up, (40 – 120 gsm paper)
alternatively it will be 0.35mm for
120 – 300 gsm paper and 0.4mm for card, at the point shown. (Fig. 22) Rotate the blade
guide eccentric towards the rear of the machine until the feeler gauge is just gripped
between the upper and lower cross cuts.
NOTE: Slowly rotate the eccentric towards the
rear of the machine. As soon as the feeler gauge is gripped stop; closing the gap too
much, will damage the cutting edge of the lower blade.
16. Once you are satisfied this has been set correctly, push on the back of the eccentric (located
inside the machine) and tighten the grub screw holding the eccentric in place. (Fig. 20)
17. Cycle the blade timing pulley anti-clockwise, (Fig. 23) until the wide end of the blade
reaches the position shown on the up stroke. (Fig. 24) The length of the upper and lower
cross cut blade overlap at this point should be approximately 20mm.
18. Push the backstop against the upper cross cut blade, (Fig. 25) apply a small amount of
pressure, then tighten into position. (Fig. 26) Complete the cycle to TDC, listening for any
knocking sound as the upper cross cut blade leaves the lower. (
A knock would mean the
backstop will have to go out further.) NOTE: This may take quite a few attempts to set
correctly.
19. Relieving some of the tension on the blade guide, (Fig. 27) cycle the upper cross cut blade
downward (Fig. 28) until the blades just overlap at the wide end of the blade, (Fig. 24) then
release the blade guide and completely cycle the blade slowly back to TDC.
NOTE: The
first few cycles must be completed very carefully, as the blades may try to jam into one
another.
20. Once you are happy the upper cross cut blade can cycle freely over the lower cross cut
blade, (Fig. 29) then it is time to test your set up with paper. Insert a single sheet of 40- 80
gsm paper between the upper and lower cross cut blades, approximately 25mm in from the
end of the lower blade with the lead on. Slowly cycle the upper cross cut blade over the
lower, the paper should be cut cleanly. (Fig. 30)
21. Re-oil the blade wicks with a small amount of light machine oil, one drop down each oil
channel. (Fig. 31) Also using light machine oil, apply one drop to the top of each blade
mount block. (Fig. 32)
