INSTALLATION & ASSEMBLY

Tools required

adjustable wrench (or socket wrench set) hex wrenches

1.If the machine is to be secured to the floor, use high quality lag screws through the four holes inside the bottom of the base. If using a mobile base, be sure to lock the wheels before assembling, operating or making adjustments to the sander. (A mobile base for your sander is available from Powermatic – stock # 708221.)

2.Mount the sander body (A) to the stand (B) with four M8 x 25 hex head screws, four M8 lock washers and four M8 flat washers as shown in Figure 3.

3.The drive belt (C) is already mounted on the drive sheave (D) behind the disc, as shown in Figure 4. However, it should be checked to ensure that it is in the sheave groove.

4.Position the belt (C) around the motor sheave (E) and tension the belt by adjusting the nuts (F) on the tensioning screw.

NOTE: Proper tension is achieved when there is moderate deflection in the belt midway between the two sheaves.

ELECTRICAL CONNECTIONS

Wire the sander in accordance with the requirements of the National Electrical Code (ANSI/NFPA70). See wiring diagram on pages 20-21. Make sure your power source matches the rating on the machine’s motor nameplate.
