However, because of the many variables involved with shipping, we recommend that you at least verify the following adjustments to ensure the best possible results from your new machine. Step-by-step instructions for these adjustments can be found on the pages referenced below. Factory adjustments that should be verified: ... ..........................................Page 34). ... ................................................................... adjustment (Page 65). ... ..................................Page 66). After the first 16 hours of use, the V-belts will stretch and seat into the pulley grooves. The V-belts must be properly re-tensioned after this period to avoid reducing their useful life. Refer to the V-Belts section on Page 69 for detailed instructions. -22 For Machines Mfg. Since 7/09 OP E R A T ION EVS Toolroom Lathes Operation Overview The purpose of this overview is to provide the novice machine operator with a basic understanding of how the machine is used during operation, so they can more easily understand the controls discussed later in this manual. Note: Due to the generic nature of this overview, it is not intended to be an instructional guide for performing actual machine operations. To learn more about specific operations and machining techniques, seek training from people experienced with this type of machine, and do additional research outside of this manual by reading "how-to" books, trade magazines, or websites. To complete a typical operation, the operator does the following: 1. Puts on safety glasses, rolls up sleeves, removes jewelry, and secures any clothing, jewelry, or hair that could get entangled in moving parts. 2. Examines the workpiece to make sure it is suitable for turning, then mounts the workpiece in one of the chucks or on the faceplate, and removes the chuck key from the chuck. 3. Mounts the tooling, aligns it with the workpiece, then backs it away to establish a safe startup clearance. 4. Clears all tools from the lathe. 5. Sets the correct spindle speed range for the operation, and turns the spindle speed dial all the way counterclockwise (to the lowest speed) to avoid the possibility of damage from a high speed start. 6. Checks for safe clearances by rotating the workpiece by hand at least one full revolution. 7. Moves slides to where they will be used during operation. 8. If using power feed, selects the proper feed rate for the operation. 9. Turns the main power switch ON, resets the stop button so it pops out, then moves the spindle ON/OFF lever down to start spindle rotation. The spindle will rotate counterclockwise (down and toward the operator when facing the front of the lathe). 10. Turns the spindle speed dial clockwise to the desired RPM. 11. Uses the carriage handwheels or power feed options to move the tooling into the workpiece for operations. 12. When finished cutting, moves the ON/OFF lever to the center position to turn the lathe OFF, then removes the workpiece. To reduce the risk of serious injury when using this machine, read and understand this entire manual before beginning any operations. Loose hair, clothing, or jewelry could get caught in machinery and cause serious injury or death. Keep these items away from moving parts at all times to reduce this risk. During operation, small metal chips may become airborne, leading to serious eye injury. Wear safety glasses to reduce this risk. -23 EVS Toolroom Lathes OP E R A T ION For Machines Mfg. Since 7/09 Description of Controls & Components Refer to the following figures and descriptions to become familiar with the basic controls of this machine. Main Power Switch The main power switch is shown in Figure 33. It turns master power ON/OFF to the lathe. Figure 33. Main power switch. Main Power Switch Headstock Controls D D D A D C B Figure 34. Headstock controls. E F A. Change Gear Chart: Displays the positions of the various gears for different threading or turning options. B. Spindle Speed Range Lever: Shifts the headstock into low or high range for spindle speeds between 20–400 RPM or 400–2500 RPM. C. Thread and Feed Chart: Shows the configurations of the gearbox levers to achieve a particular feed rate. D. Gearbox Levers: Move the gearbox gears into particular ratios, which then turn the leadscrew and feed rod for threading and power feed operations. E. Feed Direction Lever: Shifts the direction that the gearbox is turning, which changes the direction of the leadscrew and feed rod. F. Gearbox Range Lever: Shifts the gearbox between high, neutral, or low range and has no effect on spindle RPM. Carriage Controls G. 4-Position Tool Post Lever: Locks the rotary tool post in four possible detents. G T N M Q RS I P H Figure 35. Carriage controls. O K L J -24 For Machines Mfg.
