SECTION 6: MAINTENANCE

Basic Maintenance

Regular periodic maintenance of your lathe/mill will ensure optimum performance. Make a habit of inspecting your machine each time you use it.

Check for the following conditions and repair or replace when necessary:

•Loose mounting bolts and chuck.

•Worn switch or safety features.

•Worn or damaged cords and plugs.

•Any other condition that could hamper the safe operation of this machine.

General Lubrication

Paint all gears in Figure 48 with a good quality automotive wheel bearing grease as required to keep lubricated.

locations.

Keep the headstock oil level at 3⁄4 full (Figures

49and 50). After break-in, change the oil in the headstock with Mobil® DTE® Heavy-Medium or an equivalent grade of oil immediately and then again after three months. After that, change the oil at the same time on an annual basis or more frequently if extreme machine use requires it.

General Cleaning

Clean your machine every day or more often as needed. Make sure to unplug the lathe/mill before cleaning it. Never blow the lathe/mill off with compressed air, otherwise you will force metal shavings deep into mechanisms. Remove chips as they accumulate with rags, brushes, and a shop vacuum. Chips left on the machine soaked with water-based coolant will eventually invite oxidation and a gummy residue build up around moving parts. Cleaning will help keep your lathe/mill running smoothly. Always be safe and responsible with the use and disposal of cleaning products.

Never use acetone, gasoline, or lacquer thinner to remove stains or oil from painted surfaces. These chemicals will melt the paint. Use mineral spirits or mild household degreasers. To control surface rust on machined surfaces, wipe the unprotected metal as required with a rust inhibiting oil.
