Feed Roller Spring Tension
The infeed and out feed rollers are under spring tension so material can be feed evenly through the planer.
When stock feed is erratic or stops completely, roller pressure adjustment may be needed. Proper roller height
adjustment must be completed before adjusting roller tension. Refer to feed roller adjustment. Also the bed
rollers need to be properly adjusted. Refer to bed roller adjustment section.
The 4 adjustment screws, 2 for the infeed and 2 for the outfeed rollers are located on the top of the head
casting. See figure 31
1 Make sure the planer is disconnected from power source.
2. Start by turning the adjusting screws flush to the casting.
Tighten as needed. The rougher the material the more
tension you need on the rollers. Do not over tighten.
3 Adjust all screws to the same depth. Once this is completed
adjust the outfeed roller to have slightly more tension that
the infeed roller.
4 Lumber should feed smoothly and evenly through the planer.

Feed Rollers
1 Follow steps 1-7 above.
2 Remove the gear box cover to access to the adjusting screws.
3 To function properly the infeed roller needs to extend below
the lowest arc of the cutterhead approximately .030".
4 To adjust; loosen the jamb nut and using a 3mm Allen
wrench and a feeler gauge tighten or loosen until there
is .030" space between the Allen screw and infeed block.
Lock the setting by tightening the jam nut. Set both left and
right hand sides. See figure 29.
5 Adjust the outfeed roller using the same procedure as in step 4 and set the space between the set screw
and blocks to .020" on both the left and right hand sides. Lock the settings by tightening the jam nuts.
6 Remove the zeroing boards and replace the pulley cover, top hood, dust chute and gear box cover. Make
sure all adjustments are correct and all fasteners are secure before starting the planer.
Chip Breaker
For adjusting the chip breaker, use the same procedures for
zeroing the planer as in steps 1 through 7 above.
1 Make sure planer is disconnected from power source.
2 To function properly the chip breaker needs to extend below
the lowest arc of the cutterhead approximately .040". It’s
purpose it to snap the chips off the board and direct them
away from the cutterhead. There is no pressure bar on this
planer.
3 To adjust; loosen the jamb nut and using a 3mm Allen wrench and a feeler gauge tighten or loosen until
there is .035" space between the Allen screw and bar. Lock the settings by tightening the jam nuts. Set
both left and right hand sides. See figure 30.
4 Remove the zeroing boards and replace the pulley cover, top hood and dust chute. Make sure all
adjustments are correct and all fasteners are secure before starting the planer.
