Schedule
Cleaning &
protecting
use a brush and shop vacuum to remove chips
and debris from the mill. never blow off the mill
with compressed air, as this will force metal chips
deep into the mechanisms and may injure your-
self or bystanders.
Wipe built-up grime from the mill with a rag and a
mild solvent. remove any rust from the unpainted
cast iron surfaces of this mill, then treat them with
regular applications of products such as primrose
armor plate Way oil
, g96 ® gun treatment,
slipit ® , or Boeshield ® t-9 (see grizzly Catalog
for more details).
Lubrication
this mill has numerous moving metal-to-metal
contacts that require proper lubrication to help
ensure efficient and long-lasting mill operation.
other than lubrication points covered in this sec-
tion, all other bearings are internally lubricated
and sealed at the factory. simply leave them
alone unless they need to be replaced.
Before adding lubricant, clean debris and grime
from the devices to avoid contaminating the new
lubrication.
