SECTION 6: MAINTENANCE
Sanding belts can be cleaned ("unloaded") with
commercially-available crepe-rubber belt clean-
ers. To clean, simply press the belt cleaner up
against the moving belt and move across the
surface of the belt until all wood dust has been
removed. Grizzly's line of professional-grade
PRO-STIK
® belt cleaners can be found on Page
21.
Sanding Belts
The grinding wheel should be inspected before
every use. Use the “ring test” method on
Page
17 to verify the structural integrity. Take care in
storing grinding wheels to keep them free from
potential damage due to being dropped or having
other items dropped on them.
Replace the wheel when the wheel diameter is
reduced to 5". Operating at anything less than this
diameter does not allow the proper alignment of
the tool rest and the eye shield.
Depending on the type of grinding you do, the
grinding wheel may require periodic dressing.
Refer to the “Wheel Dressing” instructions on
Page 18 for details on how this is done.
Grinding Wheels
Always be aware of the condition of your machine.
Routinely check the condition of the following
items and repair or replace as necessary:
• Damaged or loose grinding wheel
• Loose mounting bolts
• Worn switch
• Worn or damaged cord
• Worn or damaged support bearings
• Any other condition that could hamper the
safe operation of this machine.
General
Sealed and pre-lubricated ball bearings require
no lubrication for the life of the bearings. All bear-
ings are standard sizes, and replacements can be
purchased from our Parts Department or a bear-
ing supply store.
Lubrication
Disconnect power to the
machine when perform-
ing any maintenance,
assembly or adjust-
ments. Failure to do this
may result in serious
personal injury.
