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.
•
An Industrial vacuum, capable of handling high volume of fi ne dust, such as the
VAC - 290 (Figure 5), should be used when dry grinding with this machine. If the
material being used is hazardous or contains Silica - the vacuum unit should be
capable of removing Respirable Silica and hazardous particles of less than 1
micron and if necessary, have the capability to be equipped with a HEPA fi lter.
Most standard vacuum drum type units use a paper bag fi lter. The dust created
during grinding is extremely fi ne and will clog the fi lter bag of these units and eventu-
ally damage the vacuums motor. In addition, damage to the TG-10 engine could
occur.
•
The collected debris and fi lters should be disposed of according to procedures that
comply with current EPA/OSHA standards.
To Start the Machine:
•
Tilt the machine back slightly, just enough for the disc to be clear of the slab surface.
•
Press the ON button on the power box.
•
Be sure to check motor for correct rotation.
•
Gently set the machine back down until the disc touches the slab surface and begin moving the machine.
To Stop the Machine:
•
Tilt the machine to allow the disc to clear the slab surface.
•
Press OFF button on the power 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 fl ow of water to the disc.
Only use enough water fl ow to reduce dust. Excess water fl ow will
create clean up problems and could cause a hazardous walking area.
Always use dust control when using this product, vacuum or
water mist.

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 fl at - do not attempt to grind against vertical surfaces. Be sure the machine is in the correct
operating position. (See Figure 6 on next page..)
