WARNING:
Do not allow familiarity with tools to make you careless.
Remember that a careless fraction of a second is suf-
ficient to inflict serious injury.
WARNING:
Always wear eye protection with side shields marked to
comply with ANSI Z87.1. Failure to do so could result in
objects being thrown into your eyes, resulting in possible
serious injury.
WARNING:
Do not use any attachments or accessories not recom-
mended by the manufacturer of this tool. The use of at-
tachments or accessories not recommended can result
in serious personal injury.
WARNING:
The use of this planer on materials not listed could dam-
age the planer and could cause serious personal injury.
WARNING:
Never plane workpiece with loose knots or foreign ob-
jects. Do not plane workpieces that are severely bowed,
twisted, or knotted. Cutter blades can dull, chip, or break
causing possible serious personal injury.
WARNING:
Do not force feed the workpiece through the machine.
Let the planer apply the proper feed rate.
APPLICATIONS
You may use this tool for the purpose listed below:
 Planing the surface of a piece of lumber.
THICKNESS PLANING
Thickness planing sizes workpiece to desired thickness while
creating a smooth, level surface. Thickness of each cut will
depend on type of wood (hardwood versus softwood), width
of workpiece, straightness, dryness, and grain composition.
Whenever working with a new type of wood, make thin test
cuts on a scrap piece of wood first to determine potential
problems with the workpiece.
OPERATION
PLANING TIPS
 Thickness planers work best if at least one side of the
workpiece has a flat surface. When both sides of a
workpiece are rough, use a surface planer or jointer first
to define the initial flat surface. Plane one side of the
workpiece then flip the workpiece and plane the surface
of the reverse side.
 Always plane both sides of a workpiece to reach the de-
sired thickness. This will leave the workpiece with uniform
moisture to prevent warp during the drying process.
 When one end of the workpiece is thicker than the op-
posite end by more than 1/8 in., make several cuts with
the planer starting with light planing cuts first. Remember,
light cuts create a finer finish than heavier cuts.
 Do not plane a workpiece less than 5/16 in. thick.
 Do not plane a workpiece less than 3/4 in. wide.
 Do not plane workpiece shorter than 14 in. long as this
will cause kickback.
 Do not plane more than one workpiece at a time.
 Do not lower the cutter head assembly lower than 5/16 in.
 Do not continuously use the planer set at the maximum
depth of cut (1/8 in.) or at full width of cut (12-1/2 in.).
Continuous use at maximum cutting capacities will dam-
age the motor.
 Worn cutter blades will affect cutting accuracy. Planing
with dull or nicked cutter blades may produce ridges or
rough workpiece surfaces.
 Gum and pitch on the cutter blades and feed rollers will
cause them to wear prematurely. Using a gum and pitch
remover to keep your cutter blades and feed rollers clean
will prolong their wear.
 Refer to the Maintenance section of this operator's manual
for instructions on how to remove and replace or turn the
cutter blades.
NOTE: Cutter blades are double-edged and can be turned
once to the opposite, unused edge before replacement
is required. Cutter blades must ALWAYS be replaced as
a set.
AVOIDING SNIPE
Snipe, or depressions made at either end of a workpiece
by cutter blades, can occur when the board is not properly
supported. Although snipe may be barely noticeable, it is
important to keep the workpiece parallel and flat with the
planer table to minimize snipe. Butting workpieces end-
to-end as they are fed through the planer will minimize the
problem, especially for shorter pieces, because it provides
a more stable feed.
