Planing tips
• use the full width of the planer. Alternate
between the left, the right and the middle of
the table when feeding lumber into the planer.
your knives will remain sharp much longer.
• scrape all glue off of joined boards before
planing. dried glue is extremely hard on the
knives.
• plane only natural wood fiber. do not
plane wood composites or other materials
that could break up in the planer and cause
operator injury or property damage.
• to avoid chipping, plane the workpiece with
the grain. nEVEr feed end-cut or end-
grained lumber into your planer.
• Keep your work area clear to help ensure
safe working conditions.
• Always true any cupped or warped stock on a
jointer before planing and feed the workpiece
into the planer with the flat face down. this
will ensure the workpiece will not rock or twist
as it goes through the planer.
• When possible, plane both faces of the
workpiece so that they will be parallel with
one another.
Workpiece
Inspection
some workpieces are not safe to use or may
require modification before they are.
Before cut-
ting, inspect all workpieces for the following:
• Material type: this machine is only intend-
ed for workpieces of natural wood fiber
Attempting to use workpieces of any other
material that may break apart during opera-
tion 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 dam-
age. 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 has-
ten rust and corrosion of the machine and/or
individual components.
• Excessive Warping: Workpieces with exces-
sive cupping, bowing, or twisting are danger-
ous to cut because they are unstable and
often unpredictable when being cut. do not
use workpieces with these characteristics!
• Minor cupping: Workpieces with slight cup-
ping 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.
