Powermatic 60HH, 60C operating instructions Maintenance, Rabbeting

Rabbeting

A rabbet cut requires removal of the cutter guard. Use extreme caution and keep hands clear of cutterhead. Always replace guard immediately after rabbeting operation is completed.

Refer to Figure 37.

A rabbet is a groove cut along the edge of a
board. Never rabbet a piece of wood less than
12" long. Use push blocks to rabbet cut
whenever possible.	Figure 37

1.Disconnect machine from power source.

2.Set fence for the desired width of the rabbet.

3.Check the width of the rabbet by measuring the distance from the end of a knife in the cutterhead to the fence. (See figure 17 to set knives for rabbeting.)

4.Lower infeed table 1/32" at a time and make successive cuts until the desired depth of rabbet has been obtained. NOTE: It is easier and safer to take a series of shallow cuts.

When rabbeting long pieces, follow the same procedure as for surfacing long pieces (refer to previous “Surfacing” section.)

Maintenance

Disconnect machine from power source before doing any maintenance.

The table and fence surfaces must be kept clean and free of rust for best results. Some users prefer a light coat of paste wax. Another option is talcum powder applied with a blackboard eraser rubbed in vigorously once a week, which will fill casting pores and form a moisture barrier. Products in aerosol form are also available in major hardware stores and supply catalogs. Whatever method is chosen, the coating should protect the metal and provide a smooth surface, without staining the wood.

The fence assembly should slide easily over the fence support. Keep the fence support greased.

The bearings in the cutterhead are sealed and do not require lubrication.

Gum and pitch which collect on the knives cause excessive friction as the work continues, resulting in overheating of the knives, less efficient cutting, and consequent reduction in the life of the knives. Use an oven cleaner or gum and pitch remover to wipe such residue off the knives.
