Physically check that the chisel is secure before operating. The chisel will have approximately 1-3/4” of play, but should not come out when pulled. Operating Instructions Read the entire Important Safety Information section at the beginning of this manual including all text under subheadings therein before set up or use of this product. Work Piece and Work Area Set Up Designate a work area that is clean and 1. well-lit. The work area must not allow access by children or pets to prevent distraction and injury. Route the power cord along a safe 2. route to reach the work area without creating a tripping hazard or exposing the power cord to possible damage. The power cord must reach the work area with enough extra length to allow free movement while working. Secure loose work pieces using a vise 3. or clamps (not included) to prevent movement while working. There must not be objects, such as utility 4. lines, nearby that will present a hazard while working. General Operation To prevent serious injury: Wear ANSI-approved safety goggles, ear protection, steel-toe boots, and dust mask during use. Keep feet clear of Breaker Hammer. Keep children and animals well clear of the work area. Use this tool only with a 20 AMP Circuit Breaker. This Breaker Hammer may have decreased performance for a brief period at the beginning of each use. This warm- up 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. Only use sharp tipped chisels. Dull tipped chisels can cause unneces- sary chisel movement, resulting in tool wear and possible injury. Figure 3Before each use, check the Chisel for dullness, cracks or other damage: Never use a dull or damaged Chisel. See Figure 3. Clearly mark the work area.1. Plug in the Breaker Hammer.2. Place the Chisel on the block you will be 3. breaking. NOTE: Carbon Brushes (51) will wear during use. The Breaker Hammer will cease functioning if the Brushes are worn. This does NOT mean Breaker Hammer is malfunctioning or broken, only that the worn Brushes will need to be replaced with the included Brushes by a qualified technician. Grasp the handles firmly with both hands 4. and depress the Trigger (86). As you break the block into big chunks, 5. release the Trigger (86) 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. When you are finished, release the 6. Trigger (86) and unplug the cord. Clean, then store indoors out of 7. children’s reach. Important - Replacing Carbon Brushes The Breaker Hammer will cease operation once the carbon brushes are worn. Check Carbon Brushes (51) after every hundred (100) hours of regular use. If brush change is necessary, it must be done by a qualified service technician. Figure 4Screws (1) Cover (2) 1.
