Cleaning and

Protecting

Metal chips left on the machine that have been soaked with water-based coolant will invite oxida- tion and a gummy residue build-up around the moving parts. Use a brush and shop vacuum to remove chips and debris from the working sur- faces of the mill/drill. Never blow off the mill/drill with compressed air, as this will force metal chips deep into the mechanisms and may cause injury to yourself or bystanders.

Remove any rust build-up from unpainted cast iron surfaces of mill/drill and treat with a non- staining lubricant after cleaning.

Protect other unpainted cast iron surfaces with regular applications of products like G96® Gun Treatment, SLIPIT®, or Boeshield® T-9. (See Accessories on Page 27 for more details.)

Lubrication

An essential part of lubrication is cleaning the components before lubricating them.

This step is critical because grime and chips build up on lubricated components over time, which makes them hard to move.

Clean all exterior components in this section with mineral spirits, shop rags, and brushes before lubricating.

DISCONNECT MACHINE FROM POWER BEFORE PERFORMING LUBRICATION!

Follow reasonable lubrication practices as outlined in this manual. Failure to do so could lead to premature failure of machine and will void warranty.
