Lubrication
Cleaning &
Protecting
Sawdust, wood chips, and metal chips left on the
machine will invite oxidation and a gummy residue
buildup around the moving parts. Use a brush and
shop vacuum to remove chips and debris from the
working surfaces of the mill. Never blow off the
mill 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 drill press 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
28 for offerings from Grizzly).
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.
