Breaking up concrete

1. 

Place the bit on the center of a piece of concrete.  

2. 

Grasp the handles firmly with both hands.  When you are sure that no people or 
animals are in the vicinity, and it’s safe to begin, depress the Switch (107).

3. 

As you break the concrete into big chunks, release the Switch (107) and move to 
other large pieces until all of the larger pieces are broken.  Do not try to break up 
smaller pieces with this tool as it is too powerful and aggressive to control on small 
pieces.

4. 

When you are finished, release the Switch (107) and unplug the Rotary Hammer.

Using the Rotary Hammer as a hammer drill

NOTE:  When you inset the Auger bit the Rotary Hammer will automatically convert into a 

rotary hammer. The Auger bit will rotate and hammer at the same time.  

1.

As you drill into the concrete firmly press against the material being drilled into.

4.

How to adjust the Masonry Drill (118) speed           

          
The Masonry Drill (118) speed is adjusted by turning the Speed Control Knob (100) See 
Figure 4.  The higher the number the faster the Masonry Bit (118) will spin. The Rotary 
Hammer will automatically rotate and hammer once you attach the Masonry Bit (118).
