CORRECTIVE.ACTION
1. Lower bed rollers (Page.29).
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.29).
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.31), or have it sharp-
ened; rotate/replace insert (Page.34).
1. Use a proper dust-collection system.
2. Correctly adjust chip breaker (Page.43).
1. Check moisture content is below 20% and allow to
dry if moisture is too high.
2. Replace knives (Page.31) or have them profession-
ally sharpened; rotate/replace inserts (Page.34).
1. Replace knives (Page.31) or have them profession-
ally sharpened; rotate/replace inserts (Page.34).
1. Slow down feed rate.
2. Adjust height of chip breaker (Page.43).
3. Adjust knives with knife gauge (Page. 31); remove
inserts, properly clean mounting pocket and re-
install (Page.34).
4. Replace cutterhead bearings.
1. Replace knives (Page.31) or have them profession-
ally sharpened; rotate/replace inserts (Page.34).
2. Increase feed rate.
3. Increase depth of cut.
1. Adjust feed rollers (Page.43).
