006281 Keeping the hook in this position, rotate it upwards to the angle 90°and push both ends fully in the direction of arrow as shown in the figure. 006282 NOTE: • Make sure that the driver bit is inserted straight in the screw head, or the screw and/or bit may be damaged. • When driving wood screws, predrill pilot holes to make driving easier and to prevent splitting of the workpiece. See the chart. 001904 Nominal diameter of Recommended size wood screw (mm) of pilot hole (mm) 3.1 (1/8") 2.0 - 2.2 (5/64" - 3/32") 3.5 (9/64") 2.2 - 2.5 (3/32" - 3/32") 3.8 (5/32") 2.5 - 2.8 (3/32" - 7/64") 4.5 (11/64") 2.9 - 3.2 (7/64" - 1/8") 4.8 (3/16") 3.1 - 3.4 (1/8" - 9/64") 5.1 (13/64") 3.3 - 3.6 (1/8" - 9/64") 5.5 (7/32") 3.7 - 3.9 (9/64" - 5/32") 5.8 (7/32") 4.0 - 4.2 (5/32" - 11/64") 6.1 (15/64") 4.2 - 4.4 (11/64" - 11/64") 90 006283 OPERATION Screwdriving operation 006269 First, slide the action mode change lever to the position of symbol and select the fastening torque. 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. Release the switch trigger as soon as the clutch cuts in. • If the tool is operated continuously until the battery cartridge has discharged, allow the tool to rest for 15 minutes before proceeding with a fresh battery. Drilling operation First, slide the action mode change lever to the position of symbol. Drilling in wood When 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. 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. 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. • If the tool is operated continuously until the battery cartridge has discharged, allow the tool to rest for 15 minutes before proceeding with a fresh battery. 8
