IMPORTANT SAFETY INSTRUCTIONS
READ ALL INSTRUCTIONS
FOR PERSONAL SAFETY THIS MACHINE MUST BE PROPERLY GROUNDED
The power cord of this machine is equipped with a three-prong (grounding) plug which mates with a standard
three-prong (grounding) wall receptacle to minimize the possibility of electric shock hazard. Where a
standard two-prong wall receptable is encountered, it is the personal responsibility and obligation of the
customer to have it replaced with a properly grounded three-prong wall receptacle. DO NOT, UNDER ANY
CIRCUMSTANCES, CUT OR REMOVE THE THIRD (GROUNDING) PRONG FROM THE POWER CORD.
Always unplug your machine before cleaning or making any repairs-(NOTE: We strongly recommend that you return the
unit to the factory for repair.) USE ONLY IDENTICAL REPLACEMENT PARTS TO REPAIR THIS MACHINE.

EYE PROTECTION
When operating the grinder, always protect yourself against
eye injuries from flying glass. Wear safety glasses or use
one of the Glastar eye shields. Either the glass or plastic
type is available as an option from your dealer. They mount
over the grinding head and keep flying chips from hitting the
face or hair.
VENTILATION
Openings in the grinder back and bottom are provided for ventilation. To insure reliable operation
and to protect the grinder from overheating, these openings must not be blocked or covered. Do not
place grinder near or over a radiator or heating vent. If this unit is installed within another enclosure,
be sure that adequate ventilation has been provided.
OPERATION
First install the flexible stopper in the drain hole located in the left-front corner of the water basin. Make
certain it is pushed in hard; then add water. It is not necessary to completely fill the reservoir. Add enough
water - about two cups - so the water level is at least touching the bottom of the grinding head. Then dip the
sponge in water and squeeze it several times to make certain it is thoroughly wet. Replace the sponge in its
pocket behind the grinding head, and turn on the grinder. As the head turns, water is pumped into the
sponge, keeping it soaking wet. The wet sponge keeps the diamond surface clean and cool. never use the
machine without first checking the water level and making certain the sponge is in place behind the grinding
head. If you notice a white paste or powder building up on the piece of glass being ground, the sponge is not
keeping the head wet enough. You should adjust the sponge by raising it a little higher on the head, or you
may have to add more water to the machine. If you use the diamond grinding head dry, you will considerably
shorten its life.
When you start to grind, push the glass against the grinding head with firm pressure. The diamond surface cuts better
with firm pressure against it. Excessive pressure will not hurt the diamond surface, although it may slow or stop the
motor. If this happens, don't be concerned. Just back the glass off slightly...and the motor will resume its normal speed.
If you have to make a deep cut into the glass in one specific area, it is best to use intermittent pressure. By using this
technique, you will allow the sponge to clean the glass residue from the diamond so that it cuts more efficiently.
Grinder coolant should prolong the life of the diamond head. A solution of 1 part coolant to 64 parts water or 1
tablespoon to 2 cups of water is recommended.
The head slings water as it rotates. The splash guard catches most of this water and returns it to the reservoir. If your
finger touches the diamond head when it is rotating, it will feel smooth. The diamond surface is not nearly the hazard to
fingers as is a belt sander or a silicone carbide grinding wheel.

DIAMOND GRINDING HEADS
The diamond cutting surface of the head is 5/8" (15.875 mm) high. Glastar has installed the head so that the
full 5/8" (15.875 mm) of diamond extends above the top plate. If all the glass you grind is 1/8" (3.175 mm)
thick or less, you will only use the lower one-fifth of the cutting surface. When the diamond cutting surface
dulls, lower the head 1/8" (3.175 mm). This will provide a new, sharp grinding surface. When that area dulls,
lower the head another 1/8" (3.175 mm) and so forth. This will allow five surfaces; each surface should last
approximately 20 to 50 hours, a total of 100 to 250 hours of grinding from one head. If you grind 1/4" (6.350
