Secondary Drum Alignment- With the primary drum properly aligned, use the same thickness gauge, and insert
it between the secondary drum and the table from the back side of the machine. (Again, adjust the contact between
the drum and guide so the drum can barely be turned by hand.) Measure at both sides of the drum to check that
the secondary drum is parallel to the table. To adjust the secondary drum alignment, use the right and left drum
adjustment knobs
(See Figure 27) to raise or lower each side of the drum. At this point both the primary and
secondary drums will be aligned parallel to the table and both drums will be at the same height above the table. Set
the secondary drum adjustment indicators by loosening the hex nut
(See Figure 27) , moving the scale so that the zero mark is directly under the needle, and retightening the hex nut.
Zero the indicator for other side of drum in the same manner.
Caution: Do not overtighten the hex nut of the indicator (See Figure 27) . This can flare the brass bushing and
render the indicator inoperable. Also, the secondary drum adjustment knobs should turn with a slight resistance to
avoid any movement during operation. To adjust knob resistance-Use the Adjustment Knob the lower Nylon Inserted
Loack Nut Below.
Note: The nut of the rear bolt on the rear (secondary) drum bearing bracket should be backed off a quarter-turn from
being fully tightened. This allows the lock washer under the rear bolt on the rear bracket to be depressed slightly,
but not completely. After alignment is completed, lower the motor mount to re-establish V-belt tension. Tighten two
screws in belt guard.
