NOTE: If a bed and feed roll gauge is not
available, use a finished block of wood with
notches cut out for the table rollers, and a
feeler gauge. See Figure 13 for an example
of a wood block used as a gauge.)
2. Move the gauge to the extreme right end of
the infeed roller and check the
measurement. It should be 1/16” below the
knife measurement. If it is not, loosen the
nut (B, Fig. 14), place a wrench upon the
flats of the screw (C, Figure 14) and turn the
screw as needed, to raise or lower the
infeed roller at the right end.
3. Move the gauge to the extreme left end of
the infeed roller and check the
measurement. If it is not 1/16” below the
knife, make the same adjustment for the left
end of the infeed roller.
IMPORTANT: Both ends of the infeed roller
should be the same height to help avoid
skewing the material as it is fed through the
machine.
To adjust the TENSION of the infeed roller:
1. Rotate the lock nut (A, Fig. 14), clockwise to
increase tension, counterclockwise to
decrease.
Do not over-compress the
spring on the infeed roller! Carefully observe
the following instructions.
2. Notice that as the spring tension is adjusted,
the infeed roller moves up or down. This will
affect the height of the roller which was
previously set. After tensioning is done, the
height adjustment elements (B & C, Figure
14) should be re-adjusted to counteract the
tensioning adjustment, and to set the roller
back to the original height.
3. The spring which is located above the
bushing block (see Figure 14) must not
be compressed too tightly,
as this will
restrict movement of the infeed roller and
may cause machine damage due to flexing
of the roller. Lift up the infeed roller with
your hand – there should still be sufficient
travel in the infeed roller.
4. If necessary, continue to adjust tension and
height in combination with one another,
while being careful to prevent excess spring
compression.
5. Repeat for the other end of the infeed roller.
The tension should be equal at both ends of
the roller.
