HOW TO OPERATE AND MAINTAIN

Magna 4” Jointer--Model 4E

Purchase of the toward proficient woodworking. Like SHOPSMITH, the Jointer is designed to accomplish quickly and accurately many operations requiring tedious hours of labor if done by hand. Basically, it is a rotary cutter which will plane edges smooth and square, ready for gluing or assembling. It will also do a fine job on light surfacing cuts but should not be confused with the Thickness Planer as Jointers often are. The latter is a very heavy industrial machine designed to dress stock to exact thicknesses.

The basic usefulness of the Jointer is illustrated by a quick preview of standard operational procedure on a saw-jointer combination such as you have available with

to cover the exposed cutter head behind the fence when

doing rabbeting operations. On very wide rabbets, where

little of the cutter head is exposed, this is not necessary.

HOW TO ADJUST THE JOINTER

The Jointer has been factory adjusted and tested for accuracy. It will operate to high standards if used and maintained correctly. Correct procedures for adjustment and periodical checking are described in the following paragraphs. READ THE INSTRUCTIONS CAREFULLY. The MAGNA 4” JOINTER deserves the best of care.
