note:

  Use the weight of the Breaker Hammer to help you break up concrete.  Use the tool 

in the vertical position whenever possible.  This tool was intended to break up larger pieces 

of concrete.

IMPORTAnT - REAd BEFORE uSE

This Breaker Hammer may have decreased performance for a brief period at the beginning 

of each use.  This warmup period lasts approximately 3-5 minutes.  This happens because 

the grease inside the tool may be somewhat thick, preventing the tool from operating at full 

efficiency while the motor is cold.  

This is perfectly normal and does not indicate a problem.  

To help reduce this effect, we recommend storing this equipment in temperatures no lower 

than 50-60° F.

Chipping a Straight Line

1. 

Use chalk or another suitable writing material and mark you work surface to delineate 

the area you intend to hammer.

2. 

Plug in the Breaker Hammer.

3. 

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 Knob

.

4. 

The Breaker Hammer will begin to break the top layer of concrete.  If you push down, 

it will begin to break the next layer as well.  

5. 

Keep moving the Breaker Hammer along the line you want to section, breaking concrete 

as you go.  If the Breaker Hammer jumps off of the line or section, release the 

Switch 

Knob

 and reposition the Breaker Hammer.

6.  

When you are finished, release the 

Switch Knob

 and unplug the Breaker Hammer.

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 Knob

.

3. 

As you break the concrete into big chunks, release the 

Switch Knob

 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 Knob

 and unplug the Breaker Hammer.
