Powermatic 4224B Adjustments, Extension cords, Headstock/tailstock movement, Cam tightness

The inverter does not require any programming; it has been pre-programmed from the factory. The buttons on the face of the inverter should never be pushed at any time. Use only the controls on the front of the headstock.

If you suspect a problem with the inverter or its settings, contact Walter Meier (Manufacturing) Inc., technical service at 1-800-274-6848.

A lightning strike or power surge may cause the inverter to fail. When lathe is not in use, disconnect power plug, or have a 3- or 4-pole disconnect installed on the power side.

8.4Extension cords

An extension cord is not recommended; try to position equipment within reach of the power source. If an extension cord becomes necessary, be sure it is heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating.

Table 1 shows recommended size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

9.0Adjustments

9.1Headstock/tailstock movement

To slide headstock, loosen locking cams at rear (see A, Figure 3) with provided wrench. Always retighten cams before operating lathe.

To slide tailstock, swing locking handle (B, Figure

23)to upright position. Push locking handle forward or back to tighten tailstock in place.

Figure 23

To remove headstock, tailstock or toolrest base from bed, unscrew and remove either of the stop bolts (see B, Figure 3). After remounting these items on the Lathe, reinstall stop bolt(s).

For most turning operations, except outboard turning, the headstock should be positioned at left end of bed, and only the tailstock moved to accommodate the workpiece.

9.2Cam tightness

If headstock, tailstock or tool rest base does not tighten properly against bed when locking handle is tightened, it may need adjusting. Figure 24 uses tailstock as example:

1.Remove stop bolt on end of lathe bed, and slide tailstock off.

2.Turn tailstock on its side, and slightly tighten lock nut with a wrench. (Headstock has two nuts.)

3.Mount tailstock on bed and verify adjustment. Repeat as needed.

4.Reinstall stop bolt.
