Accessories that may be suitable for one tool, may become hazardous when used on another tool. SERVICE 23. Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury. 24. 24. USE PROPER EXTENSION CORD: Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Table 1 shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord. Table 1: Minimum gage for cord Ampere Rating Volts Total length of cord in feet 120 V 25 ft. 50 ft. 100 ft. 150 ft.

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 lubrica tion. Without proper warm-up, hammering operation is difficult. tion. Without proper warm-up, hammering operation is difficult. . 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.
