Grinder Use and Maintenance
A. Bit Use
Remember to wear safety glasses or install a protective face shield
when grinding.
1) If you are a first time user, get the feel of the grinder by turning
on the grinder and grinding a piece of scrap glass. Begin by
pushing the glass into the grinding bit using light pressure and
moving the glass back and forth across the bit (Fig.10).
2) Slowly increase the pressure until you feel comfortable with
the grinding speed and your control. You’ll quickly learn the
optimum grinding pressure for the types of glass you use.
3) Stop periodically and check the sponge placement and water
level. Grinding without water greatly reduces the life of your
grinding bits.
4) Over time, a bit may grind less effectively causing your glass
to chip this is a result of wearing away of the bit’s diamond
surface. When this happens, it is time to expose a new portion of
the diamond surface. Loosen the set screw using the hex wrench
and move the grinding bit up on the shaft to expose a new 1/8"
section of diamond.
5) Secure the bit back in place making sure to tighten it against
the flat side of the motor shaft. Reposition the sponge if needed.
B. Care Information
1) NEVER GRIND DRY. Always make sure the sponge for the
grinder bit is wet while grinding.
2) While using the grinder bit, use only light to medium pressure
on the bit. Do not push material against bit using excessive force.
Unnecessary pressure will shorten grinder and grinder bit life.
3) Clean water reservoir and Super Sponge™ after each use.
Remove water reservoir and flush out grinding residue around
the sides of the base. The drain hole (Fig.11) in the grinder box
allows water to flush through the drain (Fig.12) when cleaning or
if using large volumes of water when grinding.
4) If the grinding bit becomes dry, add water directly to the Super
Sponge™.
5) To extend the life of the grinder, clean and lubricate the motor
shaft, inside openings of all bits and all set screws every 25 hours
of use.
6) Grinder bits should be removed from the machine if they are
not in use for a week or more. This will keep them from
“cementing” to the shaft. It will also provide you with the opportunity
(and habit) of inspecting the motor shaft and bits for proper care
and maintenance.
7) DO NOT GRIND METAL. It will make the surface unsuitable
for glass in seconds.
