OPERATION
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 safety goggles or safety glasses with side
shields when operating power tools. Failure to do so
could result in objects being thrown into your eyes re-
sulting 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 recommended
may damage the planer and may cause serious personal
injury.
WARNING:
Never plane a 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 solid wood and wood products
THICKNESS PLANING
Thickness planing sizes the workpiece to a desired thick-
ness while creating a smooth, level surface. The thickness of
each cut will depend on the 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.
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
desired thickness. This will leave the workpiece with
uniform moisture to prevent warping during the drying
process.
When one end of the workpiece is thicker than the
opposite 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 3/16 in. thick.
Do not plane a workpiece less than 3/4 in. wide.
Do not plane a 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
3/16 in.
Do not use the planer set at the maximum depth of cut
(1/8 in.) and at full width of cut (13 in.). Continuous use
at maximum cutting capacity will damage 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 will cause them to
wear prematurely. Using a gum and pitch remover to keep
the cutter blades 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.
