ST1007/12/14 15" & 20" Planers (Mfd. Since 3/16)
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 relatively
consistent surface, use less spring tension.
•
If you are planing rough lumber with inconsis-
tent 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.

To adjust roller spring tension:
1. DISCONNECT MACHINE FROM POWER!
2. Rotate tension screws clockwise to increase
tension, and counterclockwise to decrease ten-
sion until they protrude to the values shown in
Figure 63.
Note:
The rear-right spring typically requires less
tension because of forces applied from the feed
drive system. The values shown in
Figure 63
are
a starting point for further adjustment using trial
and error.
