SECTION 6: MAINTENANCE
Schedule
To reduce risk of shock or
accidental startup, always
disconnect machine from
power before adjustments,
maintenance, or service.
For optimum performance from your machine,
follow this maintenance schedule and refer to any
specific instructions given in this section.
Daily Check:
• Loose mounting bolts.
• Damaged tooling.
• Worn or damaged wires.
• Clean debris and built up grime off of machine.
• Any other unsafe condition.
Every 8 Hours of Operation:
• Check/add headstock oil (Page 31).
• Lubricate ball oilers (Page 32).
• Lubricate table/column ways and quill (Page
32).
Every 40 Hours of Operation:
• Lubricate table leadscrews (Page 33).
Every 90 Days of Operation:
• Lubricate quill rack and pinion (Page 33).
• Lubricate Z-axis leadscrew (Page 34).
Annually:
• Change headstock oil (Page 31).
Metal chips left on the machine will invite oxida-
tion and a gummy residue build-up around the
moving parts. Use a brush and shop vacuum to
remove chips and debris from the working sur-
faces of the mill/drill. Never blow off the mill/drill
with compressed air, as this will force metal chips
deep into the mechanisms and may cause injury
to yourself or bystanders.
Remove any rust build-up from unpainted cast
iron surfaces of your mill/drill and treat with a non-
staining lubricant after cleaning.
Keep unpainted cast iron surfaces rust-free with
regular applications of ISO 68 way oil (see
Page 27 for offerings from Grizzly).
Cleaning and
Protecting
Lubrication
An essential part of lubrication is cleaning the
components before lubricating them.
This step is critical because grime and chips build
up on lubricated components, which makes them
hard to move. Simply adding more lubricant will
not result in smooth moving parts.
Clean all exterior components in this section with
mineral spirits, shop rags, and brushes before
lubricating.
DISCONNECT MACHINE FROM POWER
BEFORE PERFORMING LUBRICATION.
NOTICE
Follow reasonable lubrication practices as
outlined in this manual. Failure to do so
could lead to premature failure of your
machine and will void the warranty.
