Operational Tips
•
Carefully inspect any lumber that you plan
to run through the planer. Each board must
have at least one flat surface to slide along
the planer table. To create a flat surface,
pass the stock over a jointer first. See
Figure 32.
Some defects such as moderate
twisting, loose knots or severe cracks may
make the stock planeable.
•
Only use clean stock. See
Figure 33.
Scrape off all glue from joined boards
before planing. Remove all dirt, nails,
staples, imbedded gravel, etc. from any
lumber you plan on using. A hidden nail in
a workpiece will instantly damage the
sharp edges of the knives. This will cause
unsatisfactory results in future operations.
•
Plane ONLY natural wood fiber. Never
plane wood composites such as particle
board, plywood or MDF. Never plane
laminates, formica or other synthetic
materials.
•
Surface wood in the same direction as the
grain. Never feed end-cut or end-grained
lumber into the planer.
•
Keep your work area clear. Always make
sure that long workpieces are supported
and have enough room to exit the planer.
•
When making multiple passes with the long
stock, use the top rollers to move material
back to the infeed side of the planer.
•
Avoid planing wood with a high moisture
content. Stock with more than 20%
moisture, or stock that has been exposed
to rain or snow, will plane poorly and
cause unnecessary wear on the knives and
motor. Excess moisture may also cause rust
or corrosion problems.
