Stock Inspection &
Requirements
Follow these rules when choosing and jointing
stock:
•
DO NOT joint or surface plane stock that
contains large or loose knots. Injury to the
operator or damage to the workpiece can
occur if a knot becomes dislodged during the
cutting operation.
•
DO NOT joint or surface plane against the
grain direction. Cutting against the grain
increases the likelihood of kickback, as well
as tear-out on the workpiece.
•
Jointing and surface planing with the
grain produces a better finish and is safer
for the operator. Cutting with the grain is
described as feeding the stock on the jointer so
the grain points down and toward you as viewed
on the edge of the stock (see Figure below).
Note: If the grain changes direction along the
edge of the board, decrease the cutting depth
and make additional passes.

•
Only cut natural wood. This jointer is only
designed for cutting natural wood stock.
Never use it to cut MDF, particle board, ply-
wood, laminates, drywall, backer board, metals,
glass, stone, tile, products with lead-based
paint, or products that contain asbestos. Cutting
these may lead to injury or machine damage.

•
Scrape all glue off the workpiece before
jointing. Glue deposits on the workpiece,
hard or soft, will gum up the cutterhead and
produce poor results.
•
Remove foreign objects from the work-
piece. Make sure that any stock you pro-
cess with the jointer is clean and free of dirt,
nails, staples, tiny rocks or any other foreign
objects that could damage the cutterhead.
These particles could also cause a spark as
they strike the cutterhead and create a fire
hazard.
IMPORTANT: Wood stacked on a concrete
or dirt surface can have small pieces of con-
crete or stone pressed into the surface.
•
Make sure all stock is sufficiently dried
before jointing. Wood with a moisture con-
tent over 20% will cause unnecessary wear
on the cutters and poor cutting results. Excess
moisture can also hasten rust and corrosion.
