Powermatic 701 Maintenance, Lubrication, Storage, General, Sharpening Chisel and Auger

Maintenance

Before any intervention on the machine, disconnect it from the electrical supply by pulling out the plug or switching off the main switch! Failure to comply may cause serious injury.

General

A coat of paste wax applied to the table and column will help to keep the surfaces clean.

If the power cord is worn, cut, or damaged in any way, have it replaced immediately.

The Mortiser requires only minor maintenance, such as cleaning and lubrication and routine adjustment and sharpening of the chisel and auger.

Dust the machine down after each use and, as necessary, use light applications of oil or grease to lubricate linkages, moving parts, etc.

Sharpening Chisel and Auger

The chisel and auger should be kept sharp for best performance. Blunt edges will give inaccurate mortises and can lead to overheating and breakage to chisel or auger. If chisel and auger are badly worn and become difficult to sharpen, they should be replaced.

Auger

Sharpen the auger by using a small, smooth file, following the original shape of the auger. File the inside edge of the spur, the sides of the brad point, and the cutting edge inwards toward the flute of the auger (Figure 16).

Do not file the outside edge of the spur, as this will affect the diameter of the auger.

Chisel

Referring to Figure 17:

Sharpen the chisel (A) with the chisel sharpening cone (B) located on the top of the column next to the tool holder. Set the chisel (A) on the sharpening cone (B) and rotate back and forth until sharpened (C).

Note: Make sure the set-screw is tight to prevent the cone from spinning.

Using a fine stone or micro-abrasive on a flat surface, lap the outside faces of the mortise bit to remove any burrs.

Lubrication

All of the ball bearings are packed with grease at the factory. They require no further lubrication. Periodically grease the gears, racks, and table pivot points with a #2 tube grease.

Periodically clean and oil any exposed machine surfaces, such as: dove-tail ways and slides, and table surface.

Storage

If the mortiser will be stored for an extended period, use the depth stop to help secure the head in position; this will relieve stress upon the hydraulic cylinder.
