Adjusting Feed-Roller
Spring Tension
The infeed and outfeed rollers keep the
workpiece moving through the planer. Springs
exert downward pressure on the feed rollers
while allowing them to raise with an uneven
workpiece surface. Proper spring tension is
crucial to keep the workpiece moving through the
planer during operation without pulling from one
side to the other.
The ideal feed-roller spring tension varies
depending upon the type of wood you plane.
When adjusting spring tension, keep the
following in mind:
• If you are planing milled lumber with a
consistent surface, use less spring tension to
reduce the risk of marring the workpiece.
• If you are planing rough lumber with
inconsistent 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.

Rotate tension screws clockwise to increase
tension or counterclockwise to decrease
tension (see Figure 58).

When properly distanced from the cutterhead,
the chip defl ector directs the chips into the
dust hood, and keeps them from falling onto
the outfeed roller and being pressed into the
workpiece.
4.
If distance measured in Step 3 is not equal
to correct chip deflector gap setting, then
loosen (3) flange bolts that secure chip
deflector and adjust gap to correct setting.
5.
Re-tighten flange bolts, then replace belt
cover, top cover, and dust hood.

Use cutterhead pulley to rotate cutterhead
until an insert reaches closest distance to
chip deflector (see Figure 59), then measure
distance between insert and chip deflector.
