SECTION 6: MAINTENANCE
Always disconnect power to the machine before performing maintenance. Failure to do this may result in serious person- al injury.
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.
Monthly
•Drain and clean the coolant tank, then add new fluid (Page 70).
•Change the headstock oil (Page 65).
Annually
•Change the gearbox oil (Page 66).
•Change the apron oil (Page 67).
•lubricate end gears (Page 69).
•Check/level bedway (Page 23).
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.
