Assembly Your Small Gauge Nibbler is completely assembled. Before operating the Small Gauge Nibbler, a small amount of set-up is required. It is important that you read the entire manual to become familiar with the product BEFORE you operate the Nibbler. Before operating the Nibbler be sure that you have all parts described in the Parts List and Assembly Diagram located on the last pages of this manual. 1. Make certain that the drill (not included) is unplugged and that the power is OFF. Loosen the chuck on the drill. Insert the Shank of the Nibbler into the Chuck. Make certain that the chuck is tight and that the Shank of the Nibbler is centered within the jaws. Tighten the Chuck. The Nibbler requires a minimum of 3,000 RPM. 2. The Nibbler was designed for use on certain small gauge materials. The Nibbler can be used on stainless Steel (1/64 maximum thickness), copper (1/16 ), steel (3/64 ), PVC/Tile (5/64 ) and Plastics (3/32 ). Do not use the Small Gauge Nibbler on materials that it was not intended for. Keep the Nibbler oriented vertically with the Cutting Tip (3) facing downward. 3. Make certain that the work table or work surface height and position are set so that the Nibbler travel range is sufficient for the material to be worked on. 4. Make certain that the work piece is securely clamped. It should be held in a vise or bolted to the table. Never hold the material with your bare hands while using the Nibbler. This will result in severe personal injury. 5. If the material you are using is irregularly shaped and can t be laid flat on a workbench or table, it should be securely blocked and clamped. Any tilting, twisting or shifting will result not only in errors on the line to be cut, but also increases the chances of damage to the drill. 6. Set the workpiece so that the Nibbler will not come in contact with the table or workbench while the Nibbler is operating. 7. Mark off the line or figure that you wish to have the Nibbler cut on the workpiece. Line up the Cutting Tip (3) with the workpiece-see Figure 1. It is recommended that you practice cutting with a scrap workpiece before using the desired workpiece. 8. Once the instructions above have been followed, make certain that all safety instructions have been followed and turn the drill ON.

9. Grasp Nibbler firmly BEFORE turning on the drill, and hold securely while in use. With the Drill ON, pull the Nibbler through the marked section of the workpiece to make the desired cut. See Figure 1. 10. When the work is completed turn OFF the drill, wait for the Nibbler to stop vibrating before unplugging the drill s electrical cord. Loosen the drill s chuck and remove the Nibbler. Always store tools out of reach of children. General Maintenance 1. Keep the Nibbler clean and dry. Regularly clean the Nibbler with a dry brush or clean cloth. Prevent metal, wood, dust and debris from accumulating in the motor and Cutting Tip (3) areas. 2. Periodically lubricate the Oil Port (located near the Cutter) with a light machine oil.
