SECTION 6: MAINTENANCE
Schedule
Ongoing
To maintain a low risk of injury and proper
machine operation, if you ever observe any of the
items below, shut down the machine immediately
and fix the problem before continuing operations:
• Loose mounting bolts or fasteners.
• Worn, frayed, cracked, or damaged wires.
• Guards or covers removed.
• Emergency STOP button not working cor-
rectly or not requiring you to reset it before
starting the machine again.
• A reduction in braking speed or efficiency.
• Oil level not visible in the sight glasses.
• Coolant not flowing out.
• Damaged or malfunctioning components.
Daily, Before Operations
• Check/add headstock oil (Page 65).
• Check/add gearbox oil (Page 66).
• Check/add apron oil (Page 67).
• Check/add coolant (Page 70).
• Lubricate the ways (Page 67).
• Add oil to the ball oilers (Page 68).
• Clean/lubricate the leadscrew (Page 68).
• Disengage the feed selection lever on the
apron (to prevent crashes upon startup).
• Ensure carriage lock bolt is loose.
Daily, After Operations
• Depress STOP button and shut OFF the two-
speed motor switch (to prevent accidental
startup).
• Vacuum/clean all chips and swarf from bed,
slides, and chip drawer.
• Wipe down all unpainted or machined sur-
faces with an oiled rag.

Cleaning /Protecting
Because of its importance, we recommend that
the cleaning routine be planned into the workflow
schedule.
Typically, the easiest way to clean swarf from the
machine is to use a wet/dry shop vacuum that is
dedicated for this purpose. The small chips left
over after vacuuming can be wiped up with a
slightly oiled rag. Avoid using compressed air to
blow off chips, as this may drive them deeper into
the moving surfaces or cause sharp chips to fly
into your face or hands.
All unpainted and machined surfaces should be
wiped down daily to keep them rust free and in top
condition. This includes any surface that is vulner-
able to rust if left unprotected (especially parts
that are exposed to water soluble cutting fluid).
Use a quality rust protectorate such as SLIPIT
®
or
Boeshield
®
to prevent corrosion.
Always disconnect power
to the machine before
performing maintenance.
Failure to do this may
result in serious person-
al injury.
