Powerful 1-1/2 Horsepower Motor
The Powermatic 31A is a solid, full-feature sanding machine that has a 1-1/2 horsepower TEFC (totally enclosed fan cooled) motor mounted within the enclosed base cabinet. The 31A comes wired for 115-volt, 12-amp, one-Ph current, yet it can be converted to use 230-volt, six-amp power for greater versatility.

The motor delivers power to the belt and disc units via a pair of balanced pulleys and a V-belt. The belt is easily accessible for tensioning adjustments through a large door on the rear of the base cabinet.

Fully Welded Base Cabinet for Stability
The fully welded, all-steel enclosed base cabinet measures 20.0 x 27.5 x 17.25 inches (W x H x D), providing a stable platform for the entire machine in addition to enclosing and protecting the motor and dust collection chute.

The height of the base cabinet places the disc sanding table 34.5 inches off the floor and the belt (in the horizontal position) to 37 inches. These heights plus the total weight (246 pounds) and stability of the cabinet make the Powermatic 31A easy and comfortable to work with.

Cast-Iron Table Provides Ample Workspace
A large 17.25- by 9.0-inch cast-iron table provides a solid, spacious platform that both supports and stabilizes even the largest project pieces. 

The table tilts up to 45 degrees and is secured by large hand wheels on either side. A full-sized miter slot accepts the included miter gauge, making it easy to build specialty jigs.

Versatile, User-Friendly Operation
The Powermatic 31A offers true versatility. First, the belt can be used in both the horizontal and vertical positions--and just about any angle in between. The multipurpose cast-iron table allows you to work at different angles, giving you greater project flexibility. You can also remove the top guard for contour sanding jobs.

To help ensure long life and user-friendly operation, the Powermatic 31A features a four-inch-diameter dust port for effective dust evacuation to keep your shop and your air cleaner, improve visibility, and protect components from damaging debris. At the same time, the cast-iron table with miter gauge slots and positive stops make setup fast, accurate, and simple for any angle.
