Adjusting Feed Roller Spring Tension - Grizzly G0454ZX Owner's Manual

5. Remove dust hood, top cover, belt cover, and
gearbox cover.
6. Raise table until wood blocks get close to
cutterhead.
7.
Use belt to rotate cutterhead, and continue
raising table until blocks just barely touch
cutterhead insert at its lowest point of rotation
(BDC), then lock table in place.
Note: Upward pressure of wood blocks will
hold infeed and outfeed rollers, chip breaker,
and pressure bar at same level as insert at
BDC.
8.
Loosen jam nuts and set screws on each side
of infeed roller (see Figure 44).
9.
Using a feeler gauge, adjust set screw so
it is 0.040" from roller bushing block (see
Figure 44), then tighten jam nut. Repeat on
other side of infeed roller.

10. Repeat Steps 8–9 with outfeed roller, only
adjust the gaps to 0.020".
11. Install belt cover, top cover, and gearbox

Adjusting Feed Roller
Spring Tension
The infeed and outfeed rollers keep the workpiece
moving through the planer. Springs exert down-
ward pressure on the feed rollers while allowing
them to raise with an uneven workpiece surface.
Proper spring tension is crucial to keep the work-
piece moving through the planer during operation.
The ideal feed-roller spring tension varies depend-
ing upon the type of wood you plane. When
adjusting spring tension, keep the following in
mind:
• If you are planing milled lumber with a con-
sistent surface, use less spring tension to
reduce the risk of marring the workpiece.
• If you are planing rough lumber with incon-
sistent surfaces, use greater spring tension
to keep the stock moving through the planer.
• If the workpiece consistently stops feeding
during operation, the spring tension may
need to be increased.
