•Engine exhaust from this product contains

chemicals known to the State of California to

causecancer, birth defectsorotherreproductive

harm.

•Gasoline is extremely ﬂammable and poisonous. It

should only be dispensed in well ventilated areas,

and with a cool engine.

•Small gasoline engines produce high concentrations of car-

bon monoxide (CO) example: a 5 HP 4 cycle engine opera-

tion in an enclosed 100,000 cu. ft. area with only one change

of air per hour is capable of providing deadly concentrations

of CO in less than ﬁfteen minutes. Five changes of air in the

same area will produce noxious fumes in less than 30 min-

utes. Gasoline or propane powered equipment should not be

used in enclosed or partially enclosed areas. Symptoms of

CO poisoning include, headache, nausea, weakness, dizzi-

ness, visual problems and loss of consciousness. If symp-

toms occur - get into fresh air and seek medical attention

immediately.

Operating Controls

About the TMC-7:

• The EDCO edge grinder is 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.

Before Starting:

• Before starting, 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 diamond 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

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 in reaching

the operating speed without an excessive start-up power draw.

Once the unit 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.

For Dry Grinding:

Check materials being removed to determine if they are listed on an EPA hazardous substance list. A

breathing respirator is required to help protect the operator.

• The EDCO industrial VAC’s have available optional HEPA ﬁlter kits designed to be used when removing

hazardous materials. Standard, shop-vac style vacuums are not capable of extended operation. In addition,

these standard vacs use paper bag ﬁlters that can clog and overload the vacuum motor.

• Dry grinding creates a large volume of airborne dust. The edgers are equipped with a 1-1/2” vacuum port for

attaching a high volume industrial vacuum capable of removing particles to three microns. If the materials

involved are hazardous, or unknown and assumed hazardous, the operator must assume responsibility for the

proper handling and disposal of the hazardous material.

Note: Hazardous debris, including vacuum ﬁlters, must be disposed of properly according to OSHA and

government standards.

Replacing the Diamond Grinding Disc:

• Disconnect from power source.

• To gain access to the disc, push down on the handle in the rear optional position and pivot the unit back on

the wheels until it comes to rest on the handle. (Figures 5)

• Remove plastic cap from belt cover (Figure 4). Place 9/16” socket on top of shaft. While holding ratchet on top, place 1 1/8”

socket on nut and remove. (Figure 3)

• Replace with a new disc and reverse the procedure. (Figure 3)

Inspect drive belt:

• Remove belt cover by removing 2 bolts. (Figure 6)

• Check belt tension. On new equipment, and after installing a new belt, the belt should be re-tensioned after the ﬁrst

four hours of use. A damaged, stretched, or worn belt should be replaced with a new one.

(Figures 7 - Shown with belt cover removed.) Loosen motor mount bolts and push down slightly to tension belts.

Re-tighten motor mount bolts. Replace belt cover.

Maintenance

Make sure the the engine or motor are turned off before

performing any maintenance.

• All maintenance should be performed regularly and by qualiﬁed personnel only.

• Never work under equipment without ﬁrst properly securing the equipment to prevent

it from moving or falling. Always work on a ﬂat and level surface.

• Grease disc bearings every 4 hours of use. To access grease the ﬁtting on the TMC-7 refer to (Figure 8).

These bearings are tapered roller bearings lubricated with High Temp Lubriplate No. 930-AA, or equivalent

bearing grease. Do not over lubricate. Be sure to clean up any excess grease after lubricating the

bearings. These bearings can occassionally require adjustment. If it is evident that these bearings need

adjustment they can be accessed by removing the belt over.

• Lubricate the wheel bearings from time to time with an occasional drop or two of oil to prevent binding.

• Proper belt tension must be maintained to transmit the motor power to the grinding disc.

Damage to the motor will occur and disc life shortened if belts are not kept at the

proper tension.

• Keep the Grinders clean. Be sure the safety decals are readable and properly maintained on the machine.

Grinding/cutting/drillingofmasonry,concrete,metalandothermaterials can generate dust, mists and fumescontaining chem-

icals known to cause serious or fatal injury or illness, such as respiratory disease, cancer, birth defects or other reproductive

harm. If you are unfamiliar with the risks associated with the particular process and/or material being cut or the composition

of the tool being used, review the material safety data sheets and/or consult your employer, the manufacturers/suppliers,

governmental agencies such as OSHA and NIOSH and other sources on hazardous materials. California and some other

authorities, for instance, have published lists of substances known to cause cancer, reproductive toxicity, or other harmful

effects.

Control dust, mist and fumes at the source where possible. In this regard use good work practices and follow the recom-

mendationsof the manufacturers/suppliers,OSHA/NIOSH, andoccupational andtrade associations. Watershould beused

for dust suppression when wet grinding/cutting/drilling is feasible. When the hazards from inhalation of dust, mists and

fumes cannot be eliminated, the operator and any bystanders should always wear a respirator approved by NIOSH/MSHA

for the material being used.

Grinding/cutting/drilling of masonry, concrete and other materials with silica in their composition may give off dust or mists

containingcrystalline silica. Silica isa basic componentof sand,quartz, brickclay, granite andnumerous other mineralsand

rocks. Repeated and/or substantial inhalation of airborne crystalline silica can cause serious or fatal respiratory diseases,

including silicosis. In addition, California and some other authorities have listed respirable crystalline silica as a substance

known to cause cancer. When grinding/cutting/drilling such materials, always follow the respiratory precautions mentioned

above.
