Gap Adjustments
10 Kni e Gap
Function This is the gap between the kni e edges. Needs to be checked
with a gauge to the recommended tolerances below.
Step 1 Lockout/tag out power.
Step 2 Unbolt the guard and remove rom machine.
Step 3 Unscrew bolt holding the housing lid in place. Slide lid orward
and li t o to expose cutting chamber.
Step 4
Check the kni e gap using a eeler gauge (
Fig. 6
). The gap
should be a minimum o .050mm (.002”) and a maximum o
.075mm (.003”).
Step 5
To adjust the kni e gap, loosen the nuts holding the main
bearings to the housing. Do not totally remove tension on the
bearing bolts but leave snug. Using a brass rod and hammer or
brass hammer, strike the bearing mounting langes to adjust the
gap (Fig. 7). A ter each strike, check the kni e gap with a .050mm
(.002”) or .065mm (.0025”) eeler gauge. A ter desired gap is
obtained, evenly torque down nuts to 73 N-m (54 t-lb).
Step 6
Once bearing nuts have been ully torqued, check the kni e gap
once more to veri y no movement occurred. I movement
occurred, repeat the kni e gap process to obtain the kni e gap
tolerance o .050mm (.002”) to .075mm (.003”).
11 Feedroll Gap
Function
This is the gap
between the roll contact sur aces.
DO NOT
allow
the upper roll and lower roll to contact one another or an
extended period o time. I the rolls are touching, turn o the
machine immediately and adjust the eedroll gap. Operating the
machine with the rolls in contact will rapidly erode away the
knurling on the rolls, reducing material eeding e iciency.
Step 1 Lockout/tag out power.
Step 2 Unbolt the guard and remove rom machine.
Step 3 Loosen the two adjustment screw jam nuts located on the top o
the upper eedworks.
Step 4 Turn the screw counterclockwise (Fig. 8) to lower the upper eed
roll until it contacts the lower eedroll.

CE300AF
Page 10 o 15
Step 5
Now turn the screws in the clockwise direction to raise the upper
eedroll until a .025mm (.010”) gap is achieved between the two
rolls.
Step 6 Tighten down the jam nuts while holding the adjustment screws
stationary.
12 Material Guide Gap
Function
The Material Guides prevent material rom eeding around the
roll and tangling. They are located behind the upper and lower
eedrolls. A small gap must be maintained between the guides
and the rolls. The gap needs to be at most, ½ the thickness o
the thinnest material being ed into the machine. The gap will
widen overtime as the knurling on the eedrolls wear down and
will require the material guide gap to be adjusted.
Step 1 Lockout/tag out power.
Step 2 Unbolt the guard and remove rom machine.
Step 3 Li t chain o sprockets by irst depressing the chain tensioning
arm (Fig. 3).
Step 4
Remov
e the bolts holding the lid in place and slide orward to
remove. Rotate the upper eedworks assembly orward.
Step 5
The upper and lower material guides are each astened with two
screws. Loosen the screws holding the guide in place, and
adjust the gaps to hal the thickness o the thinnest material
being processed. Use a eeler gauge to veri y the gap.
Step 6
Once gap is achieved, tighten the screw. Double check the gaps
and rotate the eedrolls to make sure the material guides do not
contact the eedrolls.
13 Tightening Schedule Failure to do so may result in damage to the machine, injury to
the operator and/or voiding o the machine’s warranty.
Function
Due to the vibratory impact associated with the Sweed
Machinery Inc machines, it is imperative to ollow a strict bolt
tightening schedule. Failure to do so may result in damage to the
machine, injury to the operator and/or voiding o the machine’s
warranty.
