Discs:
•
Inspect the disc (Figure 8) periodically to determine it’s wear characteristics, if signs of uneven wear appear the
cause should be determined and corrected. If repairs are needed contact EDCO or your EDCO representative.
• Rigid Head can be used on uneven expansion joints, high spots, joint curls and bridge decks, removing coatings
and grinding rough concrete surfaces. Use with a vacuum or water for dust control but not the same time.
• Flex Head can be used preparing a smooth, fl at fl oor to receive a new coating, removing coatings, grind rough
concrete surfaces. Can be used with a vacuum or water for dust control but not the same time.
•
Each new machine is shipped with a RIGID HEAD (FLEX HEAD OPTIONAL) 10”/255 mm factory balanced disk.
It is important to maintain the coupling to which the disk is attached. A worn coupling, damaged bearings or a bent
shaft will cause the grinding discs to wear unevenly. (Figure 9 rigid head assembly & 9A fl ex head assembly.) It is
important to note FLEX HEAD for smooth fl at surfaces, RIGID HEAD for buckled, bumpy or rough surfaces.
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 below..)
