CUTTER ADJUSTMENTS

The positions of the cutting discs are pre-set at the factory. However,

over time, as cutting discs wear and/or are replaced, adjustments may

need to be made to maintain proper operation.

Check the cutting discs to make sure that the cutting edges are sharp,

have no nicks or dings, and are concentric. Replace if necessary.

Ensure that the discs are tight on their respective shafts by tightening

with the spanner wrench. To adjust the cutter refer to the

CUTTER ADJUSTMENT DIAGRAMS on page 9.

Note: Proper cutter adjustment must proceed in the

following order: Top Shaft Assembly End-Play, Clearance,

Depth.

Removing Top Shaft Assembly End-Play

Disengage the top cutting disc (A) by rotating the cutting disc lever

(H) counter-clockwise. Using 1- 5/16" wrench, loosen jam nut (C).

Preset thrust bearing (D) to a space of 1/8" with the adjustment pin

(included). Tighten the jam nut against thrust bearing housing (G) with

1-5/16" wrench.

(Figure 13) Remove top shaft assembly end-play by unscrewing

the outer hex-nut (F) with 9/16" wrench and adjusting the inner hex-

nut (E) in, or out. Once end-play is removed (top shaft assembly will

not slide back and forth), lock the inner hex-nut in position. Hold the

inner hex-nut with a wrench and tighten the outer hex-nut snug against

the inner hex-nut, being careful not to change the position of the inner

hex-nut. Double check that end-play has been removed. Crank cutter

handle to make sure the top shaft assembly has not been adjusted too

tight and that it rotates with just slight resistance.

Clearance Adjustment (x axis)

First, set the initial clearance between the bottom cutter (B) and top

cutting disc (A). Loosen the jam-nut until the thrust bearing rotates

freely. Engage the top cutting disc by slowly rotating the cutting disc

lever clock-wise, making sure that the top cutting disc lines up adjacent

to the bottom cutter. Adjust the thrust bearing in or out as necessary to

ensure this alignment using adjustment pin.

(Figure 14) The correct clearance adjustment for the cutter is

achieved by placing a piece of 0.003" shim stock between the top

cutting disc and the bottom cutter and adjusting until there is slight

resistance on the shim stock.

Note: When making the clearance adjustment, be sure

the outermost edge (diameter) of the top cutting disc does

not interfere with the bottom cutter when engaging cut-

ting disc lever, or damage will occur to the top cutting disc

edge.

Depth Adjustment (y axis)

(Figure 15) The depth of cut is adjusted by screwing the depth

adjustment screw (I) in, or out, until 1/32" depth of cut is achieved.

Lock adjustment screw in place with locking nut using 7/16" wrench.

Note: The correct depth adjustment allows the top cutting

disc to be fully lowered adjacent to the bottom cutter with-

out mechanical interference.
