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.
Always disconnect power
to the machine before
performing maintenance.
Failure to do this may
result in serious person-
al injury.
