Make sure the machine is fully contacting the floor and none of the tools are dislodged from their
holders. In dry grinding/slicing applications, turn the dust collector on and make sure all hose
connections are secure. Hold on to the handle of the machine with one hand and with the other
hand, turn the motor start button. Start and stop the machine once to check that all of the tools
are secure in their holders and the operator controls are working correctly. Make sure the
emergency stop button is operating correctly each time the machine is started. If a tool becomes
dislodged, you will hear a clunk noise and you must immediately stop the motor and re-attach the
tool. A smooth sound will result from of the tools in their holders. Grasp the handle of the
machine with both hands and steady your stance to control the movement of the machine.

The proper method of operating the machine is to swing the machine from side to side in a
sweeping motion, while pushing the machine in a forward direction. With this movement, the most
productive pattern can be created allowing for greater production capacity and even coverage of
the work area. See figure 8. If the machine is left running on one area of the floor too long, it will
create a depression in the surface. This result is usually not desired and may require corrective
repairs to those areas. The Blastrac BMG-2500 has a unique floating head coupling system that
follows the contours of the floor and attacks the high spots first.
It is important to recognize that
in order for the machine to remove materials from the low spots on the floor, it must
reduce the surrounding higher areas first.
The sweeping side-to-side motion of the machine
will help even out the floor. If the floor has severe differences in elevations from high to low areas,
the choice must be made to either remove the entire floor down to the low spots or to fill the low
areas by other methods or techniques.
