3. The cutterhead guard must be in place and
operating properly (except when rabbeting).
4. Infeed table set for desired depth of cut.
5. Stand away from the cutterhead and turn
the machine on for a few moments. Listen
for any odd noises, rubbings, vibrations, etc.
Correct such problems before attempting
operations on the jointer.
6. Carefully check your workpiece for knots,
holes, staples or any foreign material that
might damage knives or pose a risk of
kickback. Also check the workpiece for grain
orientation.
Hand Placement
At the start of the cut, the left hand holds the
workpiece firmly against the infeed table and
fence while the right hand pushes the workpiece
in a smooth, even motion toward the cutterhead.
After the cut is under way, the new surface rests
firmly on the outfeed table. The left hand is
transferred to the outfeed side and presses
down on this part of the workpiece, at the same
time maintaining flat contact with the fence. The
right hand presses the workpiece forward and
before the right hand reaches the cutterhead it
should be moved to the work on the outfeed
table. Never pass hands directly over the
cutterhead.
Surfacing
Always use a hold down or
push block when surfacing stock.
Jointing the face of stock, or surfacing, is shown
in Figure 40. Adjust the infeed table for depth of
cut. Cuts of approximately 1/16” at a time are
recommended, as this allows better control over
the material being surfaced. More passes can
then be made to reach the desired depth.
Edge Jointing
This is the most common operation for the
jointer. Set fence square with the table. Depth of
cut should be the minimum required to obtain a
straight edge. Do not make cuts deeper than
1/8" in a single pass. Hold the best face of the
workpiece firmly against the fence throughout
the feed. See Figure 41.
