When properly installed, there will be a .002" gap
between the front blade and the front of the
upper blade (K), and the gap between the side
blades will be equal on both sides (J).
17.
Adjust the bolster adjusting screws (I),
and bolster hold-back screws (D), until the
clearance between the upper blade and the
lower blade is correct.
Adjust all four bolster-adjusting screws (I) until
the clearance between the upper blade and lower
blades is the same on each side. Adjust the hold-
back screws (D) until the clearance at the front
blade is .002".
18.
Tighten the hex nuts (G) that lock the
bolster hold-back screws in position.
Important: The bolster hold-back screws must
be properly adjusted and locked in place with
the hex nuts or the bolster will move from the
forces exerted during the notching operation.
Avoid damaging the machine.
All of the bolster adjusting
screws (I) must be firmly in
contact
with
the
bolster
mounting pad after the blade
clearance has been set. If any
adjusting screws are
not in contact with the
bolster mounting pad, the bolster will move
and the blades will strike each other.
19.
Tighten the jam nuts (H) which lock the
bolster adjusting screws in place. Check
the blade clearance after the jam nuts have
been tightened. If necessary, loosen the
jam nuts to correct any clearance
problems and then retighten them.
20.
Tighten the four socket head cap screws
(B) that help lock the bolster in position.
Avoid damaging the machine.
The upper blade must enter
and exit the lower blades
smoothly, with no interference.
21.
Recheck the clearance
between the blades and make any
adjustments that may be necessary.
22.
Make sure all of the locking screws and
nuts are tightened to prevent movement of
the bolster.
Important: The forces exerted on the bolster
during notching operations can cause the
bolster to become mis-aligned. It is important
to visually check the alignment of the upper
and lower blades at regular intervals.
STROKE ADJUSTMENT
The upward travel limit of the notcher is
automatically reduced when the Shear / Notch
switch is placed in the "Notch" position. It is not
necessary to adjust the notcher's stroke with the
stroke adjusting collars.
However, if you find the notcher does not cut
completely through the material, or retract high
enough to allow material to be placed under it,
