Assembly, Installing Sander on Stand

Assembly

Tools required:

wrenches – 10, 13 and 17mm hex (Allen) wrench – 8mm Cross-point screwdriver

Installing Sander on Stand

Refer to Figure 5:

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 stand (see Figure 2 for hole center dimensions). 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 – part no. 708118 – is available from Powermatic.)

2.The sander is shipped with the belt arm in horizontal position. Pull out on the index pin and raise the arm to vertical position, as shown in Figure 5. This will better balance the sander as you place it on the stand. Allow the index pin to pop back in to ensure the belt arm is secure.

3.Position the sander on the stand making sure to orient it properly, as shown. Also, make sure the loose end of the drive belt below the disc is pulled down and guided through the rectangular hole in the stand.

4.Secure the sander to the stand with four M8 x 25 hex head screws (BB), four M8 lock washers (CC) and four M8 flat washers (DD). NOTE: Hand tighten the screws only until all four are inserted; then tighten them completely with a 13mm wrench.

Refer to Figure 6:

5.The drive belt is already mounted on the disc pulley behind the disc, as shown in Figure 6. However, it should be checked to ensure that it is in the pulley groove.

6.Loosen the top hex nut on the tensioning screw with a 17mm wrench, and rotate the lower hex nut to raise the motor platform high enough to position the drive belt around the motor pulley.

7.When the belt is in the motor pulley groove, tension the belt by rotating the lower hex nut downward out of the way, and tightening the top hex nut to lower the platform. When the belt is tensioned properly, tighten the lower hex nut against the platform to secure the setting.

NOTE: Proper tension is achieved when there is moderate deflection (about 1/2”) in the belt midway between the two pulleys. After a period of use, re-check the belt tension, as new belts have a tendency to stretch slightly during the breaking-in process.
