DANGER

PROPERLY DISPOSE OF ALL ACCUMULATED MATERIALS PER OSHA AND ENVIRONMENTAL

PROTECTION AGENCY CODES AND

REGULATIONS. MANY ACCUMULATED MATERIALS CAN BE CLASSIFIED AS HAZARDOUS AND REQUIRE PROPER DISPOSAL PROCEDURES. CONTACT THE APPLICABLE GOVERNMENT AND/OR PRIVATE AGENCIES FOR SPECIFIC INFORMATION.

8)On job applications where the work process creates a considerable amount of loose material, it can become almost impossible to determine proper material removal depths and the extent of work already accomplished. The problem can be compounded if a vacuum system is not utilized. Loose material should be removed by sweeping or other, appropriate processes and the SURFACE GRINDER utilized until conditions again warrant removing the accumulated material.

STOPPING THE DFG/E SERIES ELECTRICALLY POWERED SURFACE GRINDER.

1)Stopping the SURFACE GRINDER is accomplished by moving the ON/OFF switch located on the operator handle to the OFF position. For safety considerations, it is also recommended that the extension cord be disconnected from both the SURFACE GRINDER and electric power source whenever the SURFACE GRINDER is not in use on the jobsite

STOPPING THE DFG/G SERIES GASOLINE POWERED SURFACE GRINDER.

1)Stopping the SURFACE GRINDER is accomplished by moving the engine throttle control lever to the idle speed position (depicted by the turtle). Machines powered by Honda engines can be then stopped by further moving the engine throttle control lever until the ignition system is grounded.

2)Machines powered by other engines may utilize a separate ON/OFF switch. If so equipped, turn the switch to the OFF position. Consult the material supplied by the engine manufacturer for specific information.

OPERATIONAL PARAMETERS AND TECHNIQUES

FOR THE DFG SERIES SURFACE GRINDER.

Application: All Models.

Early Age Grinding

Early age grinding is an alternative to floating and trowelling. It gets it name from the fact that the concrete is ground at an early age, after it has set but before it has gained much structural strength. The process usually involves the following steps:

1)Normal screeding of the floor.

2)Smoothing the floor surface with a skip float.

3)Cover the floor with polyethane sheeting.

4)Removing the sheeting and grinding the floor down a uniform depth of approximately 1/32 inch within 24 to 48 hours of the initial pouring.

The C06 and C10 silicon carbide grinding stones are usually used for the process, although the multi segmented, dry diamond blades can be use as an alternative with substantially greater productivity rates. The main benefit of early age grinding is that it eliminates late work in cold weather. With ordinary finishing methods, a slab cast in the morning of a cold weather day might not get finished trowelled until very late at night. With grinding, the construction crew are able to leave the job at the end of a normal work day and return 1 or 2 days later to finish the job. Early age grinding may not reduce the total number of work hours, but it usually eliminates the need for work at overtime rates, which can substantially increase total project costs.

One side benefit of early age grinding is that the process demands less skill than conventional floating and trowelling. This makes it an attractive process where skilled crew personnel may not be available. It is also an excellent procedure for concrete floors that will be eventually covered by carpet or an applied coating.

Definitions of floor flatness and levelness

The terms flatness and levelness have poorly understood meanings in everyday speech, but have important distinctions in floor construction.

Flatness is defined as planarity or lack of curvature. A more simple definition is that a flat floor is smooth and free of bumps and dips. An unflat floor is bumpy and wavy. Levelness is defined as horizontality or lack of slope. A level floor is horizontal. A floor that is unlevel is sloped or tilted.

A floor can be flat, but still not level. Some floors are specifically designed to be unlevel; they can be
