100 to 2000 rpm. Power requirement is 110 V, 60Hz. The lathes ship fully assembled, approximate net weight 395 lb PM-1030V, 365 lb PM-1022V. A sheet metal stand with two cabinets is available as an option. The spindle has a 1 inch bore, and is unusually short — just 11 inches, ideal for through-spindle work. Long service life is assured by high precision taper-roller spindle bearings, together with hardened and ground bed ways.

The button pops out when twisted clockwise a few degrees. This restores power, but does not activate motor. The PM-1022V and PM-1030V are conventional engine lathes that require little explanation except for specific details — MOTOR CONTROL speed control, thread cutting, and the saddle/cross-slide pow- er feed system.

Short, rigid workpieces mounted in a chuck can typically be machined without additional support. Long, slender workpiec- es need support near the cutting tool.
Page 20: Section 4 Servicing The Lathe
Section 4 SERVICING THE LATHE Disconnect power before any maintenance operation! Remove all machining debris and foreign objects before lubricating ANYTHING! Use the recommended lubricants or similar. Any oil is better than no oil – but only as a stop gap. GENERAL cess to the drain plug, Figure 4-1.
Page 21 LUBRICATION — APRON DRAIN & REFILL 1. Remove the apron fill plug, Figure 4-3. 2. Locate the drain plug on the underside of the apron casting. 3. Place a drain pan below the drain plug, then remove the plug. 4. Allow the oil to drain completely, then replace the drain plug.
