Powermatic PJ-882HH operating instructions Hand Placement, Surfacing, Edge Jointing, Rabbeting

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 rabbet cut requires 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.
