2. Turn on the Main Electrical Disconnect Switch (8) on the left side of the control panel.
Voltmeter (7) indicates the power source voltage, check that the voltage is within specified range;
turn on Power Source Switch with Indicator Light (1). All other power should be off.
3. Put a piece of glass that is long enough to occupy Pos.1-Pos.5 wheel on the input conveyor.
Set the Conveyor Direction Switch (11) to the glass working direction (right to left), Activate
Conveyor Transmission Switch (10), the glass should start moving. Stop Conveyor Transmission
Switch (10) or Emergency Switch (9) when the front of the glass passes the Pos. 4 wheel.
4. Turn the hand-wheel of Pos.1-Pos.5 spindles clockwise to move the wheels toward the
grinding position until the wheel touches the glass (manually turning the wheels during spindle
adjustment will help you hear the wheel touch the glass). Record the indicator’s position and then
turn the hand-wheel of the spindles anti-clockwise to move the wheels away from the glass grinding
position.
5. Restart Conveyor Transmission Switch (10), when the glass leaves the main machine to the
output conveyor, stop Conveyor, Switch (10) or Emergency Switch (9).
6. Turn the hand-wheel of Pos.1-Pos.5 spindles clockwise to move the wheels towards the glass
grinding position back to the above-mentioned adjustment position that you recorded.
Grinding Testing

.
Now all the wheels are at Zero grinding position. You can now adjust the wheel position
according to the grinding amount desired. In normal operation, Pos.1 grinds about 1/32” of the
flat-edge grinding amount. Always test with the Water Pumps running!
2. Adjust the arris wheels in so they grind the desired amount of seam. Generally keep this to a
small amount of grinding.
3. Slowly adjust the No.4 polish wheel up to achieve the best quality polish.
4. Adjust the No. 5 polish wheel up to give the best final luster, start Water Pump Switch (15),
check the coolant flow and start the Motor Switches (14), start Conveyor Transmission Switch (10).
5. Put the glass that was used for adjusting the wheel position on the input conveyor. Adjust the
wheel grind position according to the indication on the Grinding Motor Ampere Meter (2).
Quantity grinding
1. After several test runs, all the wheels are in the best grinding position. Now you can start
quantity grinding.
2. Add about 1/2 pound of synthetic diamond coolant (Cat No. 2651005) to the 45 gallon tank of
clean water and start Water Pumps, Switch (15), and check that the coolant is flowing to the wheels.
Start the Motors (Switches 12-13-14), start Conveyor Transmission Switch (10). Adjust the
transmission speed according to the glass thickness and grinding amount. Put the glass on the input
conveyor.
3. Watch the indication on the Grinding Motor Ampere Meter (2) and make up the loss of
wheels if it is necessary especially on the polishing wheel. Lower Amp readings indicate less
contact with the wheel and therefore the wheel can be adjusted closer to the glass.
