Outfeed Roller Height
1. Disconnect machine from power source.
2. Make sure the knives are set properly as
previously explained under "Knife
Adjustment."
3. Place the gauge block (F, Figure 26) on the
table directly beneath the cutterhead (D,
Figure 26).
4. Using a 0.020" (0.5mm) feeler gauge (G,
Figure 26) placed on top of the gauge block,
raise the work table until the knife just
touches the feeler gauge when the knife is
at its lowest point. Do not move the work
table any further until the outfeed roller is
adjusted.
5. Remove the feeler gauge and move the
gauge block (F, Figure 27) under one end of
the outfeed roller. The bottom of the outfeed
roller should just touch the top of the gauge
block. If an adjustment to the outfeed roller
is necessary, loosen the lock nut (J, Figure
27) and turn screw (H, Figure 27) until the
outfeed roller just touches the gauge block.
Then tighten lock nut (J, Figure 27).
6. Check and adjust the opposite end of the
outfeed roller in the same manner.
Infeed Roller Height
Use the exact same procedure for checking the
infeed roller as you did for the outfeed roller.
Use the .02" (0.5mm) feeler gauge atop the
gauge block. If adjustment is necessary, use the
lock nut and screw on each end of the infeed
roller.
Chipbreaker Height
The chipbreaker breaks off the larger chips
before the stock reaches the cutterhead. Use
the gauge block and a .02" (0.5mm) feeler
gauge to check the height of the chipbreaker,
following the same procedure as above. If
adjustment is needed:
1. Remove top cover.
2. Loosen the lock nuts (A, Figure 28) at both
ends of the chipbreaker, and turn the set
screws to raise or lower the chipbreaker as
needed. The set screws should be turned
the same amount.
3. When the chipbreaker contacts the gauge
block, tighten both lock nuts (A, Figure 28).
