8.0Machine setup

8.1Basic setup

1.Position the machine where it will be located on the shop floor. When positioning the machine, consider the type of work which will be done on it so you allow sufficient room not only for the workpieces, but also for service to the machine.

2.Open the door in the base of the machine and, using the holes in the base as a template, mark the floor for the position of the hold-down bolts.

3.Move the machine to expose the hold-down bolt marks and install anchors for the hold-down bolts.

4.Put the machine back over the hold-down anchors and bolt the machine securely to the shop floor. THIS MUST BE DONE FOR SAFE OPERATION OF THE MACHINE.

5.Establish an electrical service connection to the machine. This will vary according to the model purchased. ALL ELECTRICAL CONNECTIONS SHOULD BE MADE BY A QUALIFIED ELECTRICIAN WHO IS FAMILIAR WITH YOUR STATE AND LOCAL CODES. Many models of these machines make use of high voltages which pose a significant risk of serious injury or DEATH if proper knowledge and precautions are not used. Electrical instructions are included in section 9.0 Electrical connections.

6.Machines with belts are shipped with the belts in slack condition. During the electrical hookup phase of machine setup, the belt will have to be tightened and checked for tracking. See the Belt Replacement section for instructions on this procedure.

8.2Disc table angle adjustment

1.Disconnect power to the machine to prevent accidental start-ups.

2.Loosen the table locking knobs on either end of the table.

3.Using a machinist's square against the table and disc, set the table at exactly 90° to the disc (See Figure 15).

4.Tighten the table locking knobs.

5.Check the pointer. If it is not exactly on the zero mark, loosen the pointer attaching screw, adjust the pointer, and retighten the screw.

6.Reconnect the power to the machine.

8.3Disc table miter parallelism adjustment

1.Disconnect power to the machine to prevent accidental start-ups.

2.Set the table angle to zero.

3.Place a scale or adjustable machinist's square against either the left or right edge of the disc face and measure the distance to the miter slot edge (See Figure 16).
