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.
•oil level not visible in the sight glasses.
•Damaged or malfunctioning components.
Daily, Before Operations
•Check/add headstock oil (Page 67).
•Check/add gearbox oil (Page 68).
•Check/add apron oil (Page 69).
•lubricate the bedways (Page 69).
•add oil to the ball oilers (Page 70).
•Clean/lubricate the leadscrew (Page 69).
•disengage the feed lever and feed selection lever on the apron (to prevent crashes upon startup).
•Ensure carriage lock bolt is loose.
Daily, After Operations
•Press the EMERGENCY STOP button (to prevent accidental startup).
•Vacuum/clean all chips and swarf from bed, slides.
•Wipe down all unpainted or machined sur- faces with an oiled rag.
Every 50 Hours
•Lubricate end gears (Page 71).
Every 1000 Operating Hours
•Change the headstock oil (Page 67).
•Change the gearbox oil (Page 68).
•Change the apron oil (Page 69).
Annually
•Check/level bedway (Page 27).
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 vulnerable to rust if left unprotected (especially parts that are exposed to water soluble cutting fluid). Use a quality ISo 68 way oil (see Page 64 for offerings from Grizzly) to prevent corrosion.
