Do not plug drain hole
. Set your grinder on a collection tray or shallow
pan that will capture the excess water.
2. While grinding, hold glass firmly and move the glass from side to side
over disk. To grind an accurate 90
0
straight edge hold material
against the back of the water reservoir. To grind accurate 30
0
or 45
0
miter
edges, use the reversible bevel block (FIG.14).
3. To avoid unnecessary disk vibration, ensure a secure fit between the
disk and lower support collar.
4. Minor chipping may occur with a new disk. Chipping will stop after a
little use.
C. Care Information
1. NEVER GRIND DRY. Always make sure the sponge for the grinder bit
is wet or that water is dripping on the disk while grinding.
2. DO NOT OPERATE WITHOUT DIAMOND DISK INSTALLED. Disk acts
as a cover to keep water from dripping on the motor housing.
3. 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.
4. Clean water reservoir and Super Sponge
™
after each use. Remove water reservoir and flush out grinding
residue around the sides of the base under the disk. The drain hole in the grinder box allows water to flush
through when cleaning or if using large volumes of water on the disk when grinding.
5. If the grinding bit becomes dry, add water directly to the Super Sponge
™
.
6. To extend the life of the grinder, clean and lubricate the motor shaft, inside openings of all disks and bits
and all set screws every 25 hours of use.
7. Grinder bits and disks 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.
8.
Some rust may form on the diamond disk, this will not effect the efficiency or life of the disk.
9. DO NOT GRIND METAL. It will make the surface unsuitable for glass in seconds.
Troubleshooting
Problem
: Grinder bit, disk or disk collar has become stuck onto the motor shaft.
Solution 1
: Loosen set screws and push the bit as far down the shaft as possible. Most often the shaft
above
where the bit was mounted crusts with glass debris, coolant, hard water residue, etc. Using a small piece of
fine steel wool or scrubby, polish the end of the shaft all the way down to where the bit rests.
Solution 2
: If you can push the bit down as above, but you notice that there is a burr or scar on the round side
of the motor shaft caused by the set screw in the wrong position (it appears as a small ring cut into the shaft),
you will need to polish it out. This can often be done by using the same steel wool mentioned above, but
occasionally it requires stronger abrasives. Be very careful here! You only want to remove the scar, you do not
want to make the shaft smaller. It may be necessary to use very fine grit emery cloth or sandpaper here. But
again, be very careful, the motor shaft can be easily damaged. Once the scar is polished out, remove the bit.
Clean both the bit and shaft and use lubricant. Never tighten the bit to the round side of the motor shaft.
Solution 3
: If the bit or disk is still stuck, use a plumbers helper or vice grip to remove the bit. If further
assistance is necessary, call Diamond Tech toll free at (800) 937-9593 for tech service or to obtain a Return
Authorization Number and further instructions to send your machine in for repair.
