Flat Side of
Motor Shaft
Remove the disk retaining nut from the disk support collar which is
already installed on the base of the grinder shaft (FIG.2).
4. Using the hex wrench, loosen the screw holding the disk support collar on
the shaft and remove the collar (FIG.3).
5. Lubricate the full length of the grinder motor shaft (FIG.4), as well as the
inside opening of the disk support collar, the disk and the disk retaining nut
threads with a thin coat of anti-seize. Anti-seize lubricant helps prevent the
bit from seizing on the shaft and seals out ground glass particles.
Anti-seize is readily available at any hardware store.
6. Reinstall the disk support collar by aligning the at surface of the shaft with
the collar hex screw.
7. Line up the pin hole on the bottom of the disk with the pin on the disk
support collar and lower the disk into place (FIG.5). Push disk down rmly
to minimize disk vibration and secure by threading the disk retaining nut
onto the collar.
8. Replace the water tray, grid surface, splash guard and beveling
block (optional).
B. Bit Installation
1. Before reinstalling the grinder bit, lubricate the top of the motor shaft and
inside the bit by applying a thin coating of anti-seize lubricant.
2. Slide the bit onto the motor shaft, positioning the set screw over the at
side of the motor shaft (FIG.6). Position the bit on the shaft so at least 1/8”
of the diamond surface is exposed above the grid work surface.
3. Secure the bit to the shaft by turning the set screw clockwise with the
hex wrench.
IMPORTANT: Always secure the bit to the at side of the motor shaft.
Tightening the bit to the rounded side can scar the shaft and prevent bit
removal!
C. Sponge Installation
The technologically advanced Super Sponge™can absorb over 10 times its
weight in water. Its superior wicking ability insures a sufcient water supply to
protect the bit and keep the glass cool.
1. Wet the Super Sponge™by immersing it in water until soft and pliable.
2. Fill the water reservoir (FIG.7) about 3/4 of the way to the top. You may
add special grinding lubricant if desired.
3. When using the grinder bit, keep the slide valve closed (FIG.8).
4. Insert the sponge between the sponge holder on the work surface and
grinder bit so that the bottom of the sponge is in contact with the coolant/
water in the reservoir and the top of the sponge is in contact with the
diamond surface of the bit (sponge may be trimmed to ensure proper t).
5. The wet sponge should remain in contact with the bit while grinding
(FIG.9). Periodically rinse out the sponge to remove grinding residue.
When the sponge becomes worn, replace it.
6. Should your sponge become dry during periods of non-use, simply
immerse in water and reinstall.

Deluxe Model Only
The Diamond Max Deluxe comes with 3/4” and 1/4” Silver Bullet™Bits for
grinding versatility.
1. To install the 3/4” grinder bit, remove 1” grinder bit.
2. Snap spacing collar into the grid surface to reduce the size of the
opening (FIG.10).
3. Slide the bit onto the motor shaft, positioning the set screw over the at
side of the motor shaft. Position the bit on the shaft so at least 1/8” of the
bit surface is exposed above the grid work surface.
4. Secure the bit to the shaft by turning the set screw clockwise with the
hex wrench.
5. The 1/4” grinder bit is useful for both drilling holes and intricate grinding.
The 1/4” bit is placed directly onto the top of the shaft and tightened with
the hex screw. It can also be installed without removing the 1” or 3/4” bit by
lowering the position of these bits on the shaft and installing the 1/4” bit on
top of the existing bit. You now have two bits to work simultaneously
6. Deluxe models also come with an Easy-On™foot-switch. This switch allows
you to easily turn the grinder on or off with a simple tap of the toe. To use,
plug grinder directly into the foot-switch, then plug foot-switch into any
outlet. Turn grinder to the ON position.
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 rst 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.11).
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 at side of
the motor shaft. Reposition the sponge if needed.
B. Disk Use
1. When ready to start disk grinding, remove the grid work surface, ll the
water reservoir 3/4 full, open the slide valve (FIG.12) and replace the
surface grid. If needed, you can increase water supply to the grinding disk
by slightly enlarging the holes located behind the slide valve using a paper
clip or a ridged metal object. Use caution to prevent over-enlargement of
the holes. Your Diamond Max™comes with a drain opening on the grinder
base to prevent excess water from building up under the disk (FIG.13).
FIG.12
Slide Valve Open
DIAMOND MAX™ELITE INSTRUCTION MANUAL - PAGE 4
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 rmly and move the glass from side to side
over disk. To grind an accurate 900straight edge hold material
against the back of the water reservoir. To grind accurate 300or 450miter
edges, use the reversible bevel block (FIG.14).
3. To avoid unnecessary disk vibration, ensure a secure t 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 ush out grinding
residue around the sides of the base under the disk. The drain hole in the grinder box allows water to ush
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 efciency 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
ne 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 ne 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.
