DIAMOND DISC GRINDER
THIS IS THE FIRST GRINDER DESIGNED SPECIFICALLY FOR STRAIGHT EDGES
All glass grinders on the market (such as the G8) do a great job on curves, but they are not very easy to use on straight edges. This is the perfect tool for straight edges and because it is a diamond disc, it is far more cost effective than a belt sander.
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.
SAVE THESE INSTRUCTIONS
When operating the grinder, always protect yourself against eye injuries from flying glass. Either wear goggles or place a piece of glass in the eye shield slot. Use double strength glass which is a maximum of 8 1/2 inches (21.59 cm) wide.
The length of the glass depends on your height above the machine when you are grinding. We suggest a piece 7 inches (17.78 cm) tall or more.
THE WATER SYSTEM
Place the plastic cup beside the grinder so that the drain hose on the right side of the grinder is directly over the cup. Put a cup of water in the water supply basin. Lift the slide valve very slightly to allow a steady drip on the disc...If a white paste forms on the edge of the glass where you are grinding, there is insufficient water. Raise the valve a little higher. When the supply basin is dry, return the water that has collected in the plastic cup to the basin. After you have used the water serveral times, it should be discarded and replaced with fresh water. Rinse out the basin and the grinder water well every 4 hours so that the drain does not plug.
When you have finished grinding, push the slide valve all the way down. If the valve leaks, even if it has been pressed all the way down, or it is difficult to move up and down, remove it and apply a little Vaseline to the rubber surface. That should cure both problems.
STRAIGHT EDGE GRINDING
Place the piece of glass against the vertical work surface, and use it as a guide to keep your work piece perpendicular to the grinding disc. As you grind, move the glass from side to side over the disc. This applies whether the piece you are grinding is wider than the 6" (15.24 cm) disc or very narrow.
Be sure to keep the glass moving from side to side constantly. If you hold the glass stationary and some of the glass extends beyond the disc, you will grind a step in the glass at the edge of the disc. In the corner of the step, there will be very large chips.
Vary the speed as you move the glass until you find a rhythm that works best for you.
If you have a very thick piece of glass such as a drapery or 1/4" (6.350 mm) plate that you intend to fit into lead, the edges can be beveled very easily using this machine.
Note that the splash guard is sloped down to the disc. This is a 15 degree angle. Rest the piece of glass on the splash guard, then gradually slide it toward the disc. When you touch start to move the glass from side to side, you will probably want to put the same width bevel on both sides of the glass.
The size of the chipping created by the 180 grit disc (this is the standard grit on the G9) is about the same as that created by a 100 grit head on a regular Glastar grinder. A rule of thumb is that almost all of the chipping should be covered by 3/16" (4.763 mm) foil when applied to 1/8" (3.175 mm) glass.
If the amount of chipping you get with a 180 grit disc is too great, then you may want to use a finer diamond such as 360 grit.
Do not grind any metal on this disc. It can make the surface unusable for glass in a matter of seconds.
To change disc, first remove the water supply basin by pulling straight up. The splash guard is removed in the same way.
Hold the disc with one hand and loosen the aluminum screw with the other. Once the screw and washer are removed, the disc can be lifted off the hub.
This machine operates on standard household current (115 volts, 60hz, single phase, AC). The power consumption is 1.4 amps.
This machine operates on standard household current (220/240 volts, 50/60 HZ, single phase, AC). The power consumption is 0.5 amps.
