Delta RC-33 - Feed Roll Spring Tension Adjustment; Outfeed Roll Height Adjustment

ADJUSTING FEED ROLL SPRING
TENSION
The infeed roll (A) and outfeed roll (B) Fig. 50, are those
parts of yoLJr planer that feed the stock while it is being planed.
The feed rolls (A) and (B) are under spring tension and this
tension must be sufficient to feed the stock uniformly through
the planer without slipping but should not be too tight that it
causes damage to the board. The tension should be equal at
both ends of each roll.
To adjust the spring tension of the infeed roll, turn screw {C)
Fig. 51, and also the screw on the opposite end of the roll.
To adjust spring tension of the outfeed roll, turn screw (D)
Fig. 51, and also the screw on the opposite end of the planer.
ADJUSTING HEIGHT OF OUTFEED
ROLL
The outfeed roll is adjusted at the factory to be set .040"
below the cutting circle. To check and adjust the outfeed roll,
proceed as follows:
1. Disconnect machine from the power source.
2. Make sure the knives are adjusted properly as explained
underCHECKING.ADJUSTING AND REPLACING KNIVES.
3. Place the gage block (A) Fig. 52, on' the table directly
underneath the cutterhead, as shown. Using a .040" feeler
gage (B) Fig. 52, placed on top of the gage block, raise or
lower the head until the knife (C) just touches the feeler gage
when the knife is at its lowest point. Do not move the head
any further until the outfeed roll is adjusted.

4, Move the gage block (AJ Fig, 53, under one end of the
outfeed roil (B) as shown. The bottom of the outfeed roll
(B) should just touch the top of the gage block (A). If an
adjustment to the outfeed roll is necessary, loosen locknut
(E) and turn screw (F) until the feed roll just touches the gage
block. Then tighten locknut (E) Fig, 53.
5. Check and adjust opposite end of outfeed roll in the
same manner.
