MINIMUM/MAXIMUM WIDTH/HEIgHT/DEPTH
NOTE: Always plane in the direction of the grain. Support the workpiece adequately at all times. Planing material less than 3/4" wide is
not recommended. If you must plane narrow material, group several pieces together and plane them as one wide workpiece whenever
possible. The maximum depth of cut your planer can take in one pass is 1/8" (on material less than 6" wide). Never attempt to modify
your planer to take a deeper cut. Follow the recommended depth/width of cut guidelines shown in Fig. 16 for best results.
SNIPE
Snipe is a depression made when an unsupported end of your material drops toward the floor, causing the opposite end to lift up into
the cutter head.
TO AVOID SNIPE
Feed the workpiece into the planer so it is level and remains flat against the base at all times.
Keep the workpiece level throughout planing operation by receiving or "catching" it from the rear of the planer. If you are planing
material that is especially long, the use of additional material support is recommended.
TWISTED, CUPPED AND BOWED WOOD
If both sides of your material are very rough or if the material is cupped, bowed or twisted, your planer may not produce the desired
result. Ideally, you should have at least one level face/surface on your material before you plane. Your thickness planer will work best
with material that has been run through a jointer to produce one flat surface. If you do not have at least one flat surface or a jointer,
see the following recommendations.
TO PLANE TWISTED WOOD
Twisted wood may jam your planer. If a jam occurs, turn the power "OFF" , disconnect the power supply and
raise the carriage to release the workpiece from the cutter.
If your material is only slightly twisted, plane both sides alternating from one to the other until the desired thickness is reached.
TO PLANE CUPPED WOOD
To obtain the best possible results with cupped wood, rip the material down the middle and plane it as two separate pieces. Ripping
the material reduces the severity of the cup and allows the machine to deliver better results. Understand that you will have to remove
more material on cupped wood to achieve the desired thickness than you would on a normal board.
If ripping the material is not an option:
Plane one side of the material until flat, then plane the opposite side until it is also flat.
NOTE: Do not flip the board back and forth between each pass as recommended by the general planing directions.
TO PLANE BOWED WOOD
The feed rollers and cutter head in your planer will push the bow out of the material as it feeds. However, when the material exits the
planer, the pressure of the rollers and cutter head will release allowing the wood to spring back into a bowed formation. To properly
remove the bow, use a jointer.

HOW TO CHECk, ADJUST, AND REPLACE kNIVES
Wear gloves when you remove the knives for sharpening or replacement. The knives in this planer
are very sharp.
Disconnect the machine from the power source.
The knives supplied with your planer are double edged and reversible so that you can turn the knives end-for-end when
one edge becomes dull or chipped. To change the knives:
Disconnect machine from power source!
