For Machines Mfg. Since 7/09 SAFETY EVS Toolroom Lathes SAFETY Understanding Risks of Machinery Operating all machinery and machining equipment can be dangerous or relatively safe depending on how it is installed and maintained, and the operator's experience, common sense, risk awareness, working conditions, and use of personal protective equipment (safety glasses, respirators, etc.). The owner of this machinery or equipment is ultimately responsible for its safe use.
EVS Toolroom Lathes SAFETY For Machines Mfg. Since 7/09 5. Entanglement: Loose clothing, gloves, neckties, jewelry or long hair may get caught in moving parts, causing entanglement, amputation, crushing, or strangulation. Reduce this risk by removing/securing these items so they cannot contact moving parts. 11. Chuck Keys or Adjusting Tools: Tools used to adjust spindles, chucks, or any moving/ rotating parts will become dangerous projectiles if left in place when the machine is started.
For Machines Mfg. Since 7/09 SAFETY EVS Toolroom Lathes Additional Metal Lathe Safety 1. Clearing Chips. Metal chips can easily cut bare skin—even through a piece of cloth. Avoid clearing chips by hand or with a rag. Use a brush or vacuum to clear metal chips. 2. Chuck Key Safety. A chuck key left in the chuck can become a deadly projectile when the spindle is started. Always remove the chuck key after using it.

EVS Toolroom Lathes P R E PA R AT I O N For Machines Mfg. Since 7/09 Cleaning & Protecting The unpainted surfaces are coated at the factory with a heavy-duty rust preventative that prevents corrosion during shipment and storage. The benefit of this rust preventative is that it works very well. The downside is that it can be time-consuming to thoroughly remove. Be patient and do a careful job when cleaning and removing the rust preventative.
For Machines Mfg. Since 7/09 P R E PA R AT I O N EVS Toolroom Lathes Weight Load Location Refer to the Machine Specifications for the weight of your machine. Make sure that the surface upon which the machine is placed will bear the weight of the machine, additional equipment that may be installed on the machine, and the heaviest workpiece that will be used. Additionally, consider the weight of the operator and any dynamic loading that may occur when operating the machine.
EVS Toolroom Lathes P R E PA R AT I O N Lifting & Moving 4. This machine and its parts are heavy! Serious personal injury may occur if safe moving methods are not used. To reduce the risk of a lifting or dropping injury, ask others for help and use power equipment. To further balance the load, loosen the carriage lock bolt (see Figure 6), disengage the half nut lever, put the feed control lever in neutral, then use the carriage handwheel to move the carriage next to the tailstock.

O P E R AT I O N EVS Toolroom Lathes For Machines Mfg. Since 7/09 Offsetting Aligning The tailstock can be offset from the spindle center line for turning tapers. The offset movement is controlled by set screws on both sides of the tailstock (see Figure 57), and the amount of movement is indicated by the offset scale on the back of the tailstock. The offset of your lathe was aligned with the spindle center line at the factory.
For Machines Mfg. Since 7/09 O P E R AT I O N Note: As long as this dead center remains in the chuck, the point of the center will remain true to the spindle center line. The point will have to be refinished whenever the center is removed and then returned to the chuck. 5. Install a center in the tailstock. 6. Attach a lathe dog to the piece of stock from Step 3, then mount it between the centers, as shown in Figure 60. 9. EVS Toolroom Lathes Use a caliper to measure both ends of the workpiece.
