Possible Solution
7. Sharpen/replace knives; set knife alignment/height
correctly (Page 27).
8. Test by rotating shaft; rotational grinding/loose
shaft requires bearing replacement.
9. Replace bearing(s).
Possible Solution
1. Lower bed rollers (Page 42).
2. Shim outfeed extension wing level with main table.
3. Raise height of chipbreaker or pressure bar
(Page 42).
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. Lower/raise bed rollers (Page 42).
3. Raise height of chipbreaker or pressure bar
(Page 42).
4. Lower/raise feed rollers (Page 42).
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 chipbreaker to correct height.
5. Replace affected knife (Page 27), or have it
sharpened; rotate/replace insert (Page 29).
1. Use a proper dust collection system.
2. Correctly adjust chip breaker (Page 42).
1. Check moisture content is below 20% and allow to
dry if moisture is too high.
2. Replace knives (Page 27) or have them
professionally sharpened; rotate/replace inserts
(Page 29).
