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.
