Use a bull point, cold chisel, scaling chisel, etc. cAUTION: · Do not rotate the change lever when the tool is running under load. To avoid rapid wear on the mode change mechanism, be sure that the change lever is always positively located in one of the two or three action mode positions. The revolutions and blows per minute can be adjusted just by turning the adjusting dial. the dial is marked 1 (lowest speed) to 5 (full speed). Refer to the table below for the relationship between the number settings on the adjusting dial and the revolutions/ blows per minute. The torque limiter will actuate when a certain torque level is reached. As soon as the torque limiter actuates, switch off the tool immediately. This will help prevent premature wear of the tool. After drilling the hole, use the blow-out bulb to clean the dust out of the hole. Turn the tool on and apply slight pressure on the tool so that the tool will not bounce around, uncontrolled.
