REP 4.1 Cut Stick Replacement
The cut stick (PL 5.3 Main Assembly 59000
(3/14)) should be changed or rotated with every
knife change. It may require changing more of-
ten if deep grooves or jagged edges can be
seen along the score marks. A worn cut stick
can negatively affect cut quality.
The cut stick can be rotated 8 times before dis-
posal. It is located in the table beneath the
knife, accessed through the door at the rear of
the machine.
WARNING
Disconnect and lockout power as described
in the Power Lockout Procedure on page ix.
Initial Actions
Locate the Cut Stick Puller provided with the
machine. It is stored on the inside of the rear
door. The cut stick puller has a finger hold and
hook (Figure 4-1).
Procedure
1. Switch the main power OFF and lockout
power to the machine.
2. Move the waste bin aside and open the rear
door.
3. Locate the Cut Stick Puller provided with the
machine. It is stored on the inside of the
rear door. The cut stick puller has a finger
hold and hook (Figure 4-1).
4. Hook the Cut Stick Puller over the right end
of the cut stick (Figure 4-2) with a finger in
the loop of the puller. Keep the Cut Stick
Puller in-line with the cut stick.
5. Pull the Cut Stick Puller at a slight angle
(Figure 4-2) over the cut stick until the end
of the cut stick comes out of the table.
6. Remove the remaining cut stick from the ta-
ble by hand.
7. Inspect the cut stick for wear. It may be
used 8 times (twice on each surface) before
disposal. To use a surface twice, reinstall
the cut stick by turning it such that end that
came out of the right end of the slot goes
into the left end of the slot. If a surface has
been used twice, rotate the stick to an un-
used surface before reinstalling (Figure 4-3).
If all (4) surfaces have been used twice, re-
place the stick with a new one (PL 5.3 Main
Assembly 59000 (3/14)).
8. Place the left end of the cut stick into the ta-
ble slot first, sliding the end under the cut
stick retainer. Then press the rest of the cut
stick all the way down into the slot. The top
of the cut stick should be flush with the ta-
ble.
9. Securely close the rear door and replace the
waste bin.
