Periodic maintenance requirements
During operation, periodically vacuum and brush chips
and debris from machine.
Operate knee and table lead screws through full range
of movement to evenly distribute lubricant.
Apply light machine oil to work table and other exposed
metal surfaces to prevent rust or corrosion.
Remove vent panels to check pulleys and belts for
unusual wear or grooving.
NOTE:
Operators should vary
speed occasionally to prevent formation of grooves on
pulley surfaces.
