When the reversing switch lever is in the neutral position, the switch trigger cannot be pulled. CAUTION: •Alwayscheck the direction of rotation before operation. •Use the reversing switchonlyafter the tool comes toa complete stop. Changing the direction of rotation before the tool stops may damage the tool. •When not operating the tool, always set the reversing switch lever to the neutral position. 001896 Speed change To change the speed, first switch off the tool and then slide the speed change lever to the “2” side for high speed or “1” side for low speed. Be sure that the speed change lever is set to the correct position before operation. Use the right speed for your job. CAUTION: •Always set the speed change lever fully to the correct position. If you operate the tool with the speed change lever positioned halfway between the “1” side and “2” 1 1.Speedchangelever side, the tool may be damaged. 1212 1.Lockbutton 2.Actionmodechangelever •Do not use the speed change lever while the tool is running. The tool may be damaged. 001897 Selecting action mode This tool has an action mode change lever. For drilling, depress the lock button and then slide the action mode change lever to the left ( symbol). For screwing, slide the action mode change lever to the right ( symbol) until it is locked. If it is hard to turn the lever, first turn the chuck slightly in either direction and then turn the lever again. CAUTION: •Always slide the action mode change lever all the way to your desired mode position. If you operate the tool with the lever positioned halfway between the mode symbols, the tool may be damaged. •Do not usethe action mode change lever while the tool is running. The tool may be damaged. 123 1.Adjustingring 2.Graduations 3.Pointer 001898 Adjusting the fastening torque The fastening torque can be adjustedin16steps by turning the adjusting ring so that its graduations are aligned with the pointer on the tool body. First, slide the action mode change lever to the position of symbol. The fastening torque is minimum when the number 1 is aligned with the pointer, and maximum when the marking is aligned with the pointer. The clutch will slip at various torque levels when set at the number 1 to 16. Before actual operation, drive a trial screw into your material or a piece of duplicate material to determine which torque level is required for a particular application. CAUTION: •The adjusting ring does not lock when the pointer is positioned only halfway between the graduations. ASSEMBLY CAUTION: •Always besure that the tool is switched off and the battery cartridge is removed before carrying out any work on thetool. 001899 Installing or removing driver bit or drill bit Hold the ring and turn the sleeve counterclockwise to open the chuck jaws. Place the bit in the chuck as far as it will go. Hold the ring firmly and turn the sleeve clockwise to tighten the chuck. To remove the bit, hold the ring and turn the sleeve counterclockwise. 12 1.Sleeve 2.Ring 001900 When not using the driver bit, keep it in the bit holders. Bits 45 mm long can be kept there. 12 1.Bit 2.Bitholder OPERATION 001901 Screwdriving operation 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. CAUTION: •Make surethat 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. Nominal diameter of wood screw (mm) Recommended size 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”) •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 screwmakes 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 bedrilleddry. CAUTION: •Pressing excessively on the tool will not speed up the drilling. In fact, this excessive pressure will only serve...
