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.

Every 1000 Operating Hours

Change the headstock oil (Page 67).

Change the gearbox oil (Page 68).

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.
