5. Cover and place the machine in a dry area that is out of direct sunlight and away from hazardous fumes, paint, solvents, or gas. Fumes and sunlight can bleach or discolor paint and make plastic guards cloudy. 6. Once or twice a month, depending on the ambient humidity levels in the storage environment, wipe down the machine as outlined in Step 3. 7. Every few months, start the machine and run all gear-driven components for a few minutes. This will keep the bearings, bushings, gears, and shafts well lubricated and protected from corrosion, especially during the winter months. To prepare your machine for long-term storage (a year or more): 1. Run the lathe for 10 minutes to bring the gearboxes to operating temperature, then drain and refill the all gearboxes with fresh oil. Note: During extended storage (more than two years), any component above the oil level may rust from condensation. We recommend overfilling any sealed gearbox. However, over time there will be some seepage around some shafts and seals. If any gearbox is overfilled make sure to put a tag on the controls as a reminder for the maintenance person to correct the oil level before starting the machine. If a gearbox cannot be overfilled, every few months manually rotate the shaft or spindle to coat any exposed gears with oil. 2. Pump out the old cutting fluid, and flush the lines and tank with warm, soapy water. 3. DISCONNECT LATHE FROM POWER! 4. Thoroughly clean all unpainted, bare metal surfaces, then apply a liberal coat of way oil, a heavy grease, or rust preventative. Take care to ensure these surfaces are completely covered but that the rust preventative or grease is kept off of painted surfaces. 5. Lubricate the machine as outlined in the lubrication section. 6. Loosen or remove machine belts so they do not become stretched during the storage period. (Be sure to also affix a maintenance note near the power button as a reminder that the belts have been loosened or removed.) 7. Place a few moisture absorbing desiccant packs inside of the electrical box. 8. Cover and place the machine in a dry area that is out of direct sunlight and away from hazardous fumes, paint, solvents, or gas. Fumes and sunlight can bleach or discolor paint and make plastic guards cloudy. -64 For Machines Mfg. Since 7/09 S E RVI C E EVS Toolroom Lathes Backlash Adjustment Backlash is the amount of free play felt while switching rotation directions with the handwheel. This can be adjusted on the compound and cross slide leadscrews. Reducing backlash to less than 0.001" is impractical. Avoid the temptation to overtighten the backlash set screw while adjusting. Overtightening leads to accelerated wear of the wedge, nut, and leadscrew. Compound Leadscrew Tools Needed: Qty Hex Wrench 3mm .................................................1 Backlash is adjusted by tightening the set screws shown in Figure 125. When these screws are adjusted against the leadscrew nut, they offset part of the nut to remove play between the nut and leadscrew. If you end up adjusting the nut too tight, loosen the set screws, tap the compound a few times with a rubber or wooden mallet, and turn the handle slowly back and forth until it moves freely. To readjust the backlash, rock the handle back and forth, and tighten the screws slowly until the backlash is at approximately 0.001" as indicated on the handwheel dial. Set Screws Figure 125. Compound slide backlash adjustment set screws. Cross Slide Leadscrew Tools Needed: Qty Hex Wrench 3mm .................................................1 Hex Wrench 5mm ................................................1 Backlash is adjusted by loosening all four cap screws shown in Figure 126, and then tightening the center set screw, which pushes down on a wedge and forces the nut apart, taking up lash in the nut and leadscrew. If you end up adjusting the nut too tight, loosen the set screw, tap the cross slide a few times with a rubber or wooden mallet, and turn the handle slowly back-and-forth, until the handle turns freely. To re-adjust the backlash, rock the handle back and forth and tighten the set screw slowly until the backlash is at approximately 0.001" as indicated on the handwheel dial. Figure 126.

Since 7/09 Leadscrew End Play Adjustment After a long period of time, you may find that the leadscrew develops a small amount of end play. This lathe is designed so that leadscrew end play can be easily removed with adjustment. Tools Needed: Qty Open End Wrench 1" ............................................1 Hex Wrench 3mm .................................................1 Hex Wrench 5mm ................................................1 To remove leadscrew end play: 1. DISCONNECT LATHE FROM POWER! 2. Remove the three cap screws and end cover. 3. Loosen both retaining nut set screws shown in Figure 127. Retainer Nut with Set Screws Leadscrew Figur...
