The adjusting ring can be placed at any position. Screwdriving Hold the tool firmly and place the point of the driver bit in the screw head. Apply forward pressure to the tool to the extent that the bit will not slip off the screw and turn the tool on to start operation. 007411 007319 High tensile bolt 0 120 100 80 60 40 20 N m Fastening torque Fastening time S) Proper fastening torque (ft lbs) (87) (72) (58) (43) (29) (14) ( M12(1/2") M10(3/8") (M12) M8(5/16") (M10) (M8) (1/2") (3/8") (5/16") 0 1.0 2.0 3.0 Tightening bolts The proper fastening torque may differ depending upon the kind or size of the screw/bolt, the material of the workpiece to be fastened, etc. The relation between fastening torque and fastening time is shown in the figures. 007317 120 100 80 60 40 20 Standard bolt N m Fastening torque Fastening time S) Proper fastening torque (ft lbs) (87) (72) (58) (43) (29) (14) ( 0 1.0 2.0 3.0 M14(9/16") M12(1/2") (M14) M10(3/8") (M12) M8(5/16") (M10) (M8) 0 (9/16") (1/2") (3/8") (5/16") NOTE: • Use the proper bit for the head of the screw/bolt that you wish to use. • When fastening screw M8 or smaller, carefully adjust pressure on the switch trigger so that the screw is not damaged. • Hold the tool pointed straight at the screw. • If you tighten the screw for a time longer than shown in the figures, the screw or the point of the driver bit may be overstressed, stripped, damaged, etc. Before starting your job, always perform a test operation to determine the proper fastening time for your screw. CAUTION: • 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. The fastening torque is affected by a wide variety of factors including the following. After fastening, always check the torque with a torque wrench. 1. When the battery cartridge is discharged almost completely, voltage will drop and the fastening torque will be reduced. 2. Driver bit or socket bit Failure to use the correct size driver bit or socket bit will cause a reduction in the fastening torque. 3. Bolt • Even though the torque coefficient and the class of bolt are the same, the proper fastening torque will differ according to the diameter of bolt. • Even though the diameters of bolts are the same, the proper fastening torque will differ according to the torque coefficient, the class of bolt and the bolt length. 8 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 drilling operation CAUTION: • There is a tremendous and sudden twisting force exerted on the tool/bit at the time of hole breakthrough, when the hole becomes clogged with chips and particles, or when striking reinforcing rods embedded in the concrete. To drill in the concrete or tiles, first, turn the action mode changing lever so that the arrow on the lever points to the mark on the tool body. The adjusting ring can be aligned in any torque levels for this operation. 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. CAUTION: • 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. Screwdriving operation CAUTION: • Adjust the adjusting ring to the proper torque level for your work. When driving small wood screws or machine screws. set the action mode changing lever to the mark. Adjust the adjusting ring to the proper torque level for your work. 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 sure that the driver bit is inserted straight in the screw head, or the screw and/or bit may be damaged. • 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. NOTE: • When driving wood screws, predrill pilot holes to make driving easier and to prevent splitting of the workpiece. See the chart.
