WARNING: Always wear ANSI-approved impact safety goggles. Wear a full face shield
if you are producing metal filings or wood chips. Wear an ANSI-approved dust mask or
respirator when working around metal, wood, and chemical dusts and mists. Always wear
ear protection. Ear protection is required for any other persons in the work area.
WARNING: Be aware of flying concrete chips. Keep all spectators clear of the work
area.
WARNING: Do not operate this tool if you have back, neck, wrist, or other conditions or
injuries that will be aggravated by the severe jerking forces that this tool exerts upon its
operator.
WARNING: If the Rotary Hammer ever gets out of your control, immediately release the
Switch (107).
NOTE: Use the weight of the Rotary Hammer to help you break up concrete. Use the tool
in the vertical position whenever possible.
IMPORTANT - READ BEFORE USE
This Rotary 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 in 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 Rotary 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 (107).
4. The Rotary 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 Rotary Hammer along the line you want to section, breaking
concrete as you go. If the Rotary Hammer jumps off of the line or section, release
the Switch (107) and reposition the Rotary Hammer.
6. When you are finished, release the Switch (107) and unplug the Rotary Hammer.
