WARNING: DO NOT switch the unit on with the
material positioned under the carriage. Serious
injury could result.
Planing Basics
Proper Planing Technique

WARNING: DO NOT turn the unit on with the
material already inserted under the carriage.
Wait until the rollers and cutterhead are up to
full speed before feeding your material into
the machine.
To Plane Your Material
1. Lower the carriage to the desired height for your
first pass.
2. Turn the unit on and feed the material into the
feed rollers.
3. Examine the finished cut and adjust the carriage to the
appropriate height for your next pass.
nOTE: Flip the board back and forth between each pass.
See the Troubleshooting Guide, for additional information.
For best results, plane both sides of the workpiece to reach
a desired thickness. For example, if you need to remove 1/8"
(3 mm) from your workpiece, remove 1/16" (1.6 mm) from
each side. This not only allows the workpiece to dry with an
even moisture content, it also produces finer cuts.

WARNING: Plane only wood that is free from foreign
objects, with no loose knots and as few tight knots as
possible. Do not plane wood that is severely warped,
twisted, knotted or bowed.

WARNING: Do not place your body between the rear
of the planer and a stationary object while material is
feeding. Serious injury could result.
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" (19 mm) 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" (3 mm) [on material less than 6" (152 mm) wide].
Never attempt to modify your planer to take a deeper cut.
Follow the recommended depth/width of cut guidelines
shown in Table A for best results.
TABLE A

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 cutterhead.
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 (Fig. L)
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 (Fig. M)

WARNING: Twisted wood may jam your
thickness planer. If a jam occurs, turn the
power off, disconnect the power supply and
raise the carriage to release the material from
the cutterhead.
If your material is only slightly twisted:
Plane both sides alternating from one to the other until the
desired thickness is reached.
Fig. M
To Plane Cupped Wood (Fig. N)
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 if wood is cupped.
