Before Operation:
• Before starting the engine, perform a visual inspection of the entire machine. Be sure all fasteners are tight and
secure, check for signs of metal cracking or fatigue, inspect for damage. Be sure guards are in place, secure and
undamaged.
• Inspect diamond grinding disc. Check for loose or damaged diamond segments and replace if necessary. Check
that the damond disc has been correctly mounted and be sure it is tight. Different diamond/matrix discs wear at
different rates. Be sure to use the correct diamond/matrix combination for your specific application.
Operating Instructions
The EDCO edge grinders are designed to be used in conjunction with other EDCO surface preparation products. It’s
small, lightweight construction allows the operator to grind close to obstacles.
These units are equipped with a single 7” diameter Diamond Segmented Disc that is an aggressive surface material grinder
for removing excess concrete, epoxy mortar, urethane coatings and overlays, and non-skid abrasive coatings on steel,
concrete, or polymer slab floors. A scarifier disc is optional. This machine is capable of either wet or dry grinding.
To Start Grinding:
• Operating the machine from the rear, push down, or if operating from the front, lift the handle very slightly to shift
some of the weight off of the disc, but do not let the disc lift from the slab surface. The slight weight shift will aid
the engine in reaching the operating speed without an excessive start-up power draw. Once the engine reaches
operating speed, allow the edger-grinder to settle back down on the slab with the full weight on the disc.
• If the disc is out of balance, stop immediately and have the problem fixed or damage to the equipment will result.
For Wet Grinding:
• Water is not necessary as a coolant but rather as a means of controlling dust. Lightly dampen the floor or use a
fine mist.
Do not use an excessive amount of water . Excess water on the surface will create a dangerous, slip-
pery surface and more work during cleanup.
• Sprinkle a small amount of sand on the slab to create a slurry during grinding. The slurry tends to keep the dia-
monds free from build up and the cutting edge exposed. If a squeaking sound is heard or the machine tends to
pull to one side, the diamond segments may have filled and are no longer grinding effectively. Discontinue use of
machine. Make sure the throttle is completely closed (full stop position) to insure the engine will not accidently fire
(kick back) when removing the disc which could cause bodily injury and/or damage to the machine. Then follow
the directions for replacing the diamond disc or optional scarifier disc.
