MAINTENANCE
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.
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, oth
-
erwise you will force metal shavings deep into mecha
-
nisms. 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 chemi
-
cals will melt the paint. Use mineral spirits or mild
household degreasers
.
