Wavy Surface - Caused by poor knife height adjustment, wavy surface appears when one knife is taking deeper cuts than the rest of the knives. Recheck or reset knife height with the gauge.
Pitch & Glue
Chip Marks or Indentations - Chip indentation or chip bruising is the result of wood chips not being thrown away from the cutterhead and out of the dust chute. Instead they are carried around the cutterhead, deposited on the planed surface and crushed by the outfeed roller. Chip indenta- tions can be caused by a number of reasons, some of which are:
1.The type of lumber being planed. Certain species have a tendency to chip bruise.
2.A high moisture content (over 15%) and/or surface moisture. Typically found in air- dried stock where the surface is dry but the inside needs a longer time to season.
3.Dull knives.
4.Too much material being removed in one pass.
5.Improper knife cutting angle.
Possible Solutions:
1.Lumber must be completely dry, preferably
2.Make sure planer knives are sharp.
3.Remove less material per pass.
4.Use a smaller cutting angle or a double bevel grind (consult a reputable knife grinder).
Storing Power Cord
The underside of the outfeed extension wing con- tains a convenient cord storage area. Just fold the wing up, and wrap the cord around the stor- age wires to keep the cord neatly stowed until the next use of this portable planer.
