•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).

Every 1000 Operating Hours

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.
