Cleaning &
Protecting
Regular cleaning is one of the most important
steps in taking good care of this machine. In most
shops, each operator is responsible for cleaning
the machine immediately after using it or at the
end of the day. We recommend that the cleaning
routine be planned into the workflow schedule, so
that adequate time is set aside to do the job right.
Typically, the easiest way to clean swarf from the
ways and table is to use a wet/dry shop vacuum
that is dedicated for this purpose only. The small
chips leftover after vacuuming can be wiped up
with a slightly oiled rag. Avoid using compressed
air to blow off chips, as it may drive them deeper
into moving surfaces and could cause sharp chips
to fly into your face or hands.
All visible swarf should be removed from the mill
during cleaning.
Besides the ways, all other 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 any parts that are
exposed to water soluble coolant). Typically, a thin
film of way oil is all that is necessary for protection
(refer to Page 36 for way oil from Grizzly).

Lubrication
The mill has numerous moving metal-to-metal
contacts that require regular and proper lubrica-
tion to ensure efficient and long-lasting operation.
Other than the lubrication points covered in this
section, all other bearings are internally lubricated
and sealed at the factory. Simply leave them
alone unless they need to be replaced.
DISCONNECT MACHINE FROM POWER before
performing any lubrication task!
Important: Before adding lubricant, clean the
debris and grime from the device and the imme-
diate area to prevent contamination of the new
lubricant.
Use the schedule and information in the chart
below as a daily guide for lubrication tasks.

The recommended lubrication schedule is
based on light-to-medium usage. Keeping
in mind that lubrication helps to protect
the value and operation of the mill, these
lubrication tasks may need to be performed
more frequently depending on usage.
