Resumen del manual
Never connect the green (or green and yellow) wire to a live terminal. if your unit is for'use on less than 150 volts, it has a plug like that shown in Figure A. If it is for use on 150 to 250 volts, it has a plug like that shown in Figure D. An adapter. Figures B and C, is available for connecting Figure A plugs to two-prong receptacles. The green-colored rigid ear, lug, etc., must be connected to a permanent ground such as a properly grounded outlet box. No adapter is available for a plug as shown in Figure D. Adapter shown in Figures B & C is Not for Use in Canada. GROUNDED OUTLET BOX , AMPUR MEAMS MMKDWTtfTMXih PRONG IS LONGEST Of THE 3 B.- c. D. We recommend that you NEVER disassemble the tool or try to do any rewiring in the electrical system. Any repairs should be performed only by B&D Service Centers or other qualified service organizations. Should you be determined to make a repair yourself, remember that the green colored wire is the “grounding" wire. Never connect this green wire to a “live" terminal. If you replace the plug on the power cord, be sure to connect the green wire only to the grounding (longest) prong on a 3 prong plug. EXTENSION CORD When using the tool at a considerable distance from power source, ^ a 3-conductor, grounding-type extension cord of adequate size must be used for safety, and to prevent loss of power and over-heating. Use the table below to determine the minimum wire size required in an extension cord. Use only three wire extension cords which have three-prong grounding-type plugs and three-pole receptacles which accept the tool's plug. Replace or repair damaged cords.

First, unplug the tooi, then press together the two prongs of the Retaining Spring (see Fig. 1) and re move spring. Unscrew brush cap and remove brush and spring assembly.

Keep brushes clean and sliding freely in guides. COMMERCIAL/ INDUSTRIAL USE WARRANTY . Black & Decker warrants this product for one year from the date of purchase. We will repair without charge, any defects due to faulty material or workmanship.

Fig. 2 Fig. 3 First, swing the Tool Retaining Spring (located In front of the nose piece) to one side. Insert tool bit into nose piece until shoulder on tool bit bottoms on nose piece. (NOTE: If tool bit does not bottom, hold Hammer so that tool bit Is touching the ground, and push the Hammer sharply downward to seat the tool bit.) Next, swing Tool Retaining Spring back into place so that it engages the shaft of the tool *btt. OPERATION Grasp handle of Hammer with one hand, and the barrel of Hammer with the other hand (see Fig. 2). If using Star Drills, grasp Hammer handle and the Turning Handle (see Fig. 3). Place tool in working position and depress trigger. When using Star Drills, swing Turning Handle in a 180° arc about 30 times per minute to prevent binding and to remove cuttings; exert firm even pressure for best results. NOTE: Use Dust Shield for all' overhead drilling. For best demolition performance always place the end of the bit close to an edge of the work, breaking the work away piece by piece (Fig. 4). Trying to break away too large a chunk may cause the bit to get stuck in the work and may also decrease demolition rate. Fig, 4 LUBRICATION The most important point in keeping your Electric Hammer free* running and powerful is regular oiling. Oil cups are located In the gear case under the switch handle. Oil liberally (several squirts from the can) after every 3 hours of Hammer operation« In overhead work, oil Hammer, through the nose piece rather than through the oil cups. Excess oiling will cause some leakage around the tool shank, but this does no damage and Hammer will clear itself rapidly in operation. Black & Decker Special Hammer Oil (See Hammer'Supplies* this booklet) has special qualities for adhering to high speed working parts and will greatly prolong the life of the tool. In an emergency, use high grade SAE No. 30 Oil. In from 30 days to 3 months, depending upon use, your Ham* mer sou id be sent to the nearest B&D Service Branch for a complete cleaning and replacement of lubricant in the gear case. Your Hammer will be returned to you completel...
