Hand Placement; Surfacing; Edge Jointing; Rabbeting - Powermatic PJ-882 Manual De Operación Y Partes

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.

Rabbeting

A
removal of the guard. Use extreme caution
and keep hands clear of cutterhead. Always
re-install guard immediately after rabbeting
operation is completed.
A rabbet is a groove cut along the edge of a
board. See Figure 42. The width and thickness
of the wood to be rabbeted depends upon the
width and length of the rabbet. However, never
rabbet a piece of wood less than 12" long.
Use push blocks to rabbet cut whenever
possible. The rabbeting capacity is 1/2".
1. Disconnect jointer from power source.
2. Set fence for desired width of rabbet.
3. Check width of the rabbet by measuring the
distance from the end of a knife in the
cutterhead to the fence.

IMPORTANT: Rabbeting can be done with the
straight knife cutterhead only; it is not applicable
with the helical cutterhead model.
