Possible Solution
1. Hold workpiece up slightly as it leaves outfeed end
of planer.
2. Plane lumber longer than your intended workpiece
length, then cut off excess after planing complete.
1. Reduce depth of cut (Page 36). Reduce cutting
depth when planing hard woods.
2. Clean internal cutterhead components with pitch/
resin dissolving solvent.
1. Inspect workpiece for knots and grain direction; only
use clean stock, and cut WITH the grain (Page 26).
2. Reduce depth of cut. (Reduce cutting depth when
planing hard woods.) (Page 36)
3. Rotate/replace insert(s) (Page 38).
1. Use proper dust collection system.
1. Check moisture content is below 20% and allow to
dry if moisture is too high (Page 27).
2. Rotate/replace insert(s) (Page 38).
1. Rotate/replace insert(s) (Page 38).
1. Remove insert(s), properly clean mounting pocket,
and re-install (Page 38).
2. Check/replace cutterhead bearings.
1. Rotate/replace insert(s) (Page 38).
2. Increase depth of cut (Page 36).
1. Adjust chain and sprockets (Page 52); replace if
necessary.
1. Tighten/replace insert(s) (Page 38).
2. Replace belt (Page 46).
3. Check/replace cutterhead bearings.
4. Tighten/replace cutterhead.
