G0675 10" Jointer/Planer Combo Machine
Here are some rules to follow when choos-
ing stock for the jointer/planer:
• DO NOT joint or surface plane stock that
contains knots. Injury to the operator or
damage to the workpiece can occur if the
knots become dislodged during the cutting
operation.
• DO NOT joint or surface plane against the
grain direction. Cutting against the grain
increases the likelihood of stock 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 so the grain
points down and toward you on the jointer
(Figure 28) or away from you on the planer
(Figure 29), as viewed from the edge.
Note: If the grain changes direction along the
edge of the board, decrease the cutting depth
and make additional passes.

• Remove foreign objects from the stock.
Make sure that any stock you process with
the jointer/planer is clean and free of any dirt,
nails, staples, tiny rocks or any other foreign
objects, which if they hit the knives and are
drawn into the dust collector, may cause a
fire hazard. The particles may also damage
the knives. Wood stacked on a concrete floor
can have small pieces of stone or concrete
pressed into the surface.
• Only process natural wood fiber through
your jointer/planer. Never joint MDF, par-
ticle board, plywood, laminates or other syn-
thetically made materials.
• Make sure all stock is sufficiently dried
before jointing or planing. Wood with a
moisture content over 20% will cause unnec-
essary wear on the knives and poor cutting
results. Excess moisture can also hasten rust
and corrosion.
• Scrape all glue off of boards before plan-
ing.
• Keep your work area clear.
