SECTION 6: MAINTENANCE
Schedule
To reduce risk of shock or
accidental startup, always
disconnect machine from
power before adjustments,
maintenance, or service.
Metal chips and other debris left on the machine
will invite oxidation and a gummy residue build-up
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 mill and treat them with a
non-staining lubricant after cleaning.
Keep unpainted cast iron surfaces rust-free
with regular applications of products like G96
®
Gun Treatment, SLIPIT
®
, or Boeshield
®
T-9 (see
Figure 57 and the Grizzly catalog or website).

Regular maintenance will help ensure proper
care of the equipment. We strongly recommend
that all operators make a habit of following the
maintenance procedures found in this section.
For optimum performance from this machine, this
maintenance schedule must be strictly followed.
Ongoing
To maintain a low risk of injury and proper
machine operation, if you ever observe any of the
items below, shut the machine down immediately,
disconnect it from power, and fix the problem
before continuing operations.
• Loose mounting bolts or fasteners.
• Worn, frayed, cracked, or damaged wires.
• E-STOP button not working correctly.
• Worn or loose V-belts (see Page 52).
• Missing or open belt guards/door.
• Coolant not flowing correctly.
• Any other unsafe condition.
Before Beginning Operations
• Press the E-STOP button on the control
panel to prevent high-speed spindle startup
when connected to power.
• Make sure the X-axis power feed is turned
OFF to prevent unintentional table movement
when connected to power.
• Check the coolant reservoir in the base. Fill it
or clean it out if necessary (see Page 51).
• Perform all required lubrication tasks (see
Page 45).
• Check table movement in all three axes for
loose/tight gibs. Adjust the gibs if necessary.
Daily, After Operations
• Push the E-STOP button, turn the mas-
ter power switch OFF, and disconnect the
machine from power.
• Vacuum/clean all chips and swarf from table,
slides, and base.
• Wipe down all unpainted or machined sur-
faces with a high-quality rust preventative.
