·Due to our continuing program of research and development, the specifications herein are subject to change without notice.

·Note: Specifications may differ from country to country.

Power supply

The tool should be connected only to a power supply of the same voltage as indicated on the nameplate, and can be operated on single-phase AC/DC supply. They are double-insulated in accordance with Euro- pean Standard and can, therefore, also be used from sockets without earth wire.

Safety hints

For your own safety, please refer to the enclosed Safety instructions.

ADDITIONAL SAFETY RULES

1.Wear a hard hat (safety helmet), safety glasses and/or face shield. It is also highly recom- mended that you wear a dust mask, ear pro- tectors and thickly padded gloves.

2.Be sure the bit is secured in place before operation.

3.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.

4.In cold weather or when the tool has not been used for a long time, let the tool warm up for several minutes by operating it under no load. This will loosen up the lubrication. Without proper warm-up, hammering operation is dif- ficult.

5.Always be sure you have a firm footing.

Be sure no one is below when using the tool in high locations.

6.Hold the tool firmly with both hands.

7.Keep hands away from moving parts.

8.Do not leave the tool running. Operate the tool only when hand-held.

9.Do not point the tool at any one in the area when operating. The bit could fly out and injure someone seriously.

10.When drilling or chipping into walls, floors or wherever ªliveº electrical wires may be encountered, DO NOT TOUCH ANY METAL PARTS OF THE TOOL!

Hold the tool by the insulated grasping sur- faces to prevent electric shock if you drill or chip into a ªliveº wire.

11.Do not touch the bit or parts close to the bit immediately after operation; they may be extremely hot and could burn your skin.

SAVE THESE INSTRUCTIONS.

OPERATING INSTRUCTIONS

Side grip (auxiliary handle) (Fig. 1 & 2)

For maximum control and safer operation, always use the side grip with this tool. The side grip swings around to either side, allowing easy handling of the tool in any position. Loosen the side grip by turning it counterclockwise, swing it to the desired position and then tighten it by turning clockwise. (Fig. 1)

The side grip can also be installed in the position shown in Fig. 2. Remove the side grip from the grip base by turning the side grip counterclockwise. Screw the side grip on either side of the tool, whichever is convenient.
