Anleitung Zusammenfassung
If you use this tool unsafely or incorrectly, you can suffer seri ous personal injury. 1. Hold tools by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator. 2. Wear ear protectors when using the tool for extended periods. Prolonged exposure to high intensity noise can cause hearing loss. 3. Wear a hard hat (safety helmet), safety glasses and/or face shield. Ordinary eye or sun glasses are NOT safety glasses. It is also highly recommended that you wear a dust mask and thickly padded gloves. 4. Be sure the bit is secured in place before operation. 5. Under normal operation, the tool is designed to produce vibration. The screws can come loose easily, causing a breakdown or accident. Check tightness of screws carefully before operation. 6. In cold weather or when the tool has not been used for a long time, let the tool warm up for a while by operating it under no load. This will loosen up the lubrication. Without proper warm-up, hammering operation is difficult. 7. Always be sure you have a firm footing. Be sure no one is below when using the tool in high locations. 8. Hold the tool firmly with both hands. 9. Keep hands away from moving parts. 10. Do not leave the tool running. Operate the tool only when hand-held. 11. Do not point the tool at any one in the area when operating. The bit could fly out and injure someone seriously. 12. Do not touch the bit or parts close to the bit immediately after operation; they may be extremely hot and could burn your skin. 13. Some material contains chemicals which may be toxic. Take caution to prevent dust inhalation and skin contact. Follow material supplier safety data.

Pull out and then turn the tool retainer so that the dimple faces toward the large opening in the end of the tool (tool holder). The shank of the bit is then inserted into the tool holder with the notched portion on the shank facing back toward the tool retainer. Insert the bit into the tool holder as far as it will go.
