Adjusting Roller Spring Tension - Grizzly G0453W Owner's Manual

13. Loosen jam nuts and set screws on each side
of chip breaker (see Figure 69).
14. Using a feeler gauge, adjust set screw so it is
0.020" from cross bar (see Figure 69), then
tighten jam nut. Repeat on other side of chip
breaker.

Adjusting Roller
Spring Tension
The infeed and outfeed rollers keep the workpiece
moving through the planer. There are springs that
exert downward pressure on the rollers while still
allowing them to raise with an uneven workpiece
surface. Proper roller spring tension is crucial to
keep the workpiece moving through the planer
during operation.
Roller spring tension will vary depending upon the
type of wood you are planing. When adjusting the
roller spring tension keep the following in mind:
• If you are planing milled lumber with a rela-
tively consistent surface, use less spring ten-
sion.
• 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 roller spring tension
may need to be increased.
