should be a minimum of .050mm (.002”) and a maximum of
.075mm (.003”) (

Gap Adjustments
10 Knife Gap
Function
This is the gap between the knife 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 from machine.
Step 3
Unscrew bolt holding the housing lid in place. Slide lid forward
and lift off to expose cutting chamber.
Step 4
Check the knife gap using a feeler gauge (
should be a minimum of .050mm (.002”) and a maximum of
.075mm (.003”).
Step 5
To adjust the knife 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 flanges to adjust the
gap (
Fig. 7
). After each strike, check the knife gap with a .050mm
(.002”) or .065mm (.0025”) feeler gauge. After desired gap is
obtained, evenly torque down nuts to
73 N-m (54 ft-lb).
Step 6
Once bearing nuts have been fully torqued, check the knife gap
once more to verify no movement occurred. If movement
occurred, repeat the knife gap process to obtain the knife gap
tolerance of .050mm (.002”) to .075mm (.003”).
11 Feedroll Gap
Function
between the roll contact surfaces.
the upper roll and lower roll to contact one another for an
extended period of time. If the rolls are touching, turn off the
machine immediately and adjust the feedroll gap. Operating the
machine with the rolls in contact will rapidly erode away the
knurling on the rolls, reducing material feeding efficiency.
Step 1 Lockout/tag out power.
Step 2 Unbolt the guard and remove from machine.
Step 3
Loosen the two adjustment screw jam nuts located on the top of
the upper feedworks.
Step 4
Turn the screw counterclockwise (
Fig. 8
) to lower the upper feed
roll until it contacts the lower feedroll.
