Possible Solution
1. inspect/tighten loose bolts/nuts; replace damaged
components.
2. tension/replace belts as a matched set (Page 41).
3. re-align/replace shaft, pulley set screw, and key.
4. adjust bed rollers (Page 27).

necessary.
6. Fix/replace fan cover; replace loose/damaged fan.
7. Sharpen/replace knives; set knife alignment/height
correctly (Page 28).
8. replace bearing(s).
9. test by rotating shaft; rotational grinding/loose
shaft requires bearing replacement.
Possible Solution
1. lower bed rollers (Page 27).
2. Shim outfeed extension wing level with main table.
3. raise height of chip breaker (Page 43).
4. hold workpiece up slightly as it leaves outfeed end
of planer.
5. plane lumber longer than your intended workpiece
length, then cut off excess after planing complete.
1. take a lighter cut.
2. adjust bed rollers (Page 27).
3. raise height of chip breaker or pressure bar
(Page 43).
4. adjust feed rollers (Page 43).
5. Clean internal cutterhead components with a pitch/
resin-dissolving solvent.
1. inspect workpiece for knots and grain direction;
only use clean stock, and cut With the grain.
2. take a smaller depth of cut. (reduce cutting depth
when planing hard woods.)
3. Slow down feed rate.
4. adjust both sides of chip breaker to correct height.
5. replace affected knife (Page 28), or have it
sharpened; rotate/replace insert (Page 31).
1. use a proper dust-collection system.
2. Correctly adjust chip breaker (Page 43).
