Workpiece.Inspection
Some workpieces are not safe to use or may
require modification before they are.
Before.
cutting,.inspect.all.workpieces.for.the.
following:
•
Material.Type:
This machine is only
intended for workpieces of natural wood
fiber. Attempting to use workpieces of any
other material that may break apart during
operation could lead to serious personal
injury and property damage.
• Foreign.Objects: Inspect lumber for
defects and foreign objects (nails, staples,
imbedded gravel, etc,). If you have any
question about the quality of your lumber,
DO NOT use it. Remember, wood stacked on
a concrete floor can have small pieces of
stone or concrete pressed into the surface.
•. Large/Loose.Knots:. Loose knots can
become dislodged during operation. Large
knots can cause kickback and machine
damage. Always use workpieces that do not
have large/loose knots.
•. Wet.or."Green".Stock: Avoid using wood
with a high water content. Wood with more
than 20% moisture content or wood exposed
to excessive moisture (such as rain or
snow), will cut poorly and cause excessive
wear to the machine. Excess moisture
can also hasten rust and corrosion of the
machine and/or individual components.
•
Excessive.Warping:
Workpieces with
excessive cupping, bowing, or twisting are
dangerous to cut because they are unstable
and often unpredictable when being
cut. DO NOT use workpieces with these
characteristics!
• Minor.Cupping: Workpieces with slight
cupping can be safely supported if the
cupped side is facing the table. On the
contrary, a workpiece supported on the
bowed side will rock during operation and
could cause severe injury from kickback.
Wood.Types
The species of wood, as well as its condition,
greatly affects the depth of cut the planer can
effectively take with each pass.
The chart in the figure below shows the Janka
Hardness Rating for a number of commonly used
species. The larger the number, the harder
the workpiece, and the less material should be
removed in any one pass for good results.
Note:.
The Janka Hardness Rating is expressed
in pounds of force required to embed a 0.444"
steel ball into the surface of the wood to a
depth equal to half the ball's diameter.
