To Stop the Electric Model:
• Tilt the machine to allow the disc to clear the slab surface.
• Turn rotary switch to the OFF position or press OFF button on the starter box.
Wet Grinding:
• In the wet grinding stage - water is fed from a standard garden hose into a
ball valve cut off, then into a nozzle that sprays over the disc assembly.
(Figure 4)
Use the ball valve to regulate the flow of water to the disc.
Only use enough water flow to reduce dust. Excess water flow will
create clean up problems and could cause a hazardous walking area.
Always use dust control when using this product, vacuum or water mist.
Dry Grinding:
Dry Grinding creates a large volume of airborne dust. For health reasons, the operator should
wear an applicable respirator. The dust may contain chemicals known to cause serious
illnesses, including Silicosis - a fatal disease of the lungs. Check the chemical properties of the
material to be removed and follow all EPA/OSHA regulations.
Controlling the Grind:
• Grinding discs are
extremely
aggressive. It is important to
KEEP THE GRINDER MOVING IN A SIDE-TO-SIDE
MOTION,
do not let the grinder stay in one spot, even for a few seconds, or the surface will be damaged. When
grinding is completed, tilt the machine back and shut off the power.
• To achieve a smooth “polished” surface, complete the grinding operation with an EDCO dual disc unit using
grinding stones or dyma-serts.
• To remove a light coating, move the grinder quickly. For heavier removal, move the grinder more slowly.
• Keep the grinding disc
flat
- do not attempt to grind against vertical surfaces. Be sure the machine is in the correct
operating position. (See
