4. The manner of holding the tool or the material of driving position to be fastened will affect the torque. 5. Operating the tool at low speed will cause a reduction in the fastening torque. Hammer drill mode CAUTION: • Always hold the tool firmly during operation. There is a tremendous and sudden twisting force exerted on the tool/bit at the time of hole break-through, when the hole becomes clogged with chips and particles, or when striking reinforcing rods embedded in the concrete. Be sure to use a tungsten-carbide tipped bit. Position the bit at the desired location for the hole, then pull the switch trigger. Do not force the tool. Light pressure gives best results. Keep the tool in position and prevent it from slipping away from the hole. Do not apply more pressure when the hole becomes clogged with chips or particles. Instead, run the tool at an idle, then remove the bit partially from the hole. By repeating this several times, the hole will be cleaned out and normal drilling may be resumed. Drilling mode CAUTION: • Pressing excessively on the tool will not speed up the drilling. In fact, this excessive pressure will only serve to damage the tip of your bit, decrease the tool performance and shorten the service life of the tool. • There is a tremendous force exerted on the tool/ bit at the time of hole break through. Hold the tool firmly and exert care when the bit begins to break through the workpiece. • A stuck bit can be removed simply by setting the reversing switch to reverse rotation in order to back out. However, the tool may back out abruptly if you do not hold it firmly. • Always secure small workpieces in a vise or similar hold-down device. • Do not pull the switch trigger repeatedly when the motor is locked. It may damage the tool. For drilling in wood, the best results are obtained with wood drills equipped with a guide screw. The guide screw makes drilling easier by pulling the bit into the workpiece. For drilling in metal, to prevent the bit from slipping when starting a hole, make an indentation with a center-punch and hammer at the point to be drilled. Place the point of the bit in the indentation and start drilling. Use a cutting lubricant when drilling metals. The exceptions are iron and brass which should be drilled dry. NOTE: • Choose suitable speed for the work load. Drilling over the following capacity may damage the tool. - High speed Low speed Drilling capacity Steel 6.5 mm (1/4") Wood 12 mm (15/32") Steel 10 mm (3/8") Wood 21 mm (13/16") Screwdriver mode CAUTION: • Adjust the number on the LED display to the proper torque level for your work. • Make sure that the driver bit is inserted straight in the screw head, or the screw and/or bit may be damaged. • Hold the tool firmly. When the clutch cuts in or refastening, a sudden twisting force may occur and it can twist your wrist. Place the point of the driver bit in the screw head and apply pressure to the tool. Start the tool slowly and then increase the speed gradually. NOTE: • This tool employs an electronic clutch. The tool stops automatically when the clutch cuts in. To keep operating, release the switch trigger once. • When driving wood screw, pre-drill a pilot hole 2/3 the diameter of the screw. It makes driving easier and prevents splitting of the workpiece. • See the following chart for the relation between the number of torque setting and fastening torque rate. The fastening torque rate will be different depends on materials. Make a test fastening to get the desired torque before operation. Number on LED Display 1 3 5 7 9 Fastening torque rate Low (1) High (2) Approx. 2.5 N•m Approx. 1.1 N•m (Approx. 1.8 ft•lbs) (Approx. 0.8 ft•lbs) Approx. 4.6 N•m Approx. 2.0 N•m (Approx. 3.3 ft•lbs) (Approx. 1.4 ft•lbs) Approx. 8.1 N•m Approx. 3.0 N•m (Approx. 5.9 ft•lbs) (Approx. 2.2 ft•lbs) Approx. 10.0 N•m Approx. 4.0 N•m (Approx. 7.3 ft•lbs) (Approx. 2.9 ft•lbs) Approx. 11.5 N•m Approx. 5.8 N•m (Approx. 8.4 ft•lbs) (Approx. 4.2 ft•lbs) 12 ENGLISH
