Machine Storage

To avoid rust problems or corrosion damage, use the following information to protect your invest- ment when storing the mill for any length of time.

disCONNECT MILL FROM POWER!

lubricate the mill as directed in the Lubrication section beginning on Page 44.

thoroughly clean all unpainted, bare metal surfaces, then coat them with a light weight grease or rust preventative. Take care to ensure these surfaces are completely cov- ered but that the grease or rust preventative is kept off painted surfaces.

Note: If the machine will be out of service for only a short period of time, use way oil or a good grade of medium-weight machine oil (not auto engine oil) in place of the grease or rust preventative.

loosen the belts to prevent them from stretch- ing during storage. Post a reminder on the mill that the belts need to be re-tensioned before resuming operations.

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 plastic parts.

At least once a month, start the mill 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.
