When the charging light goes out after about one hour, you may remove the fully charged battery cartridge. After charging, unplug the charger from the power source. CAUTION: 0 Your new battery cartridge is not charged. You will need to charge it before use. .Do not keep the button pressed in with tape, etc. or the circuit will not function pro- perly. Also, a malfunction of the charger may result possibly causing overheating, etc. 0 If you try to charge a cartridge from a just-operated tool, sometimes the charging light will not come on. If this occurs, let the cartridge cool off for a while. Then re-insert it and try to charge it once more. 0 When you charge a new battery cartridge or a battery cartridge which has not been used for a long period, it may not accept a full charge. This is a normal condition and does not indicate a problem. You can recharge the battery cartridge fully after discharging it almost completely a couple of times. 0 If you wish to charge two battery cartridges, allow 15 minutes between chargings on the fast charger. Use only the driver bit or socket bit shown in the figure. 11 mm Do not use any other driver bit or socket (7/16") bit. 9mm (3/8") To install the bit, pull the sleeve in the direction of the arrow and insert the bit into the sleeve as far as it will go. Then release the sleeve to secure the bit. Sleeve To remove the bit, pull the sleeve in the direction of the arrow and pull the bit out firmly. NOTE : If the bit is not inserted deep enough into the sleeve, the sleeve will not return to its original position and the bit will not be secured. In this case, try re-inserting the bit according to the instructions above. Switch action Tool speed is increased by increasing pres- sure on the trigger. To start the tool, simply pull the trigger. Release the trigger to stop. CAUTION: Before inserting the battery cartridge into the tool, always check to see that the trigger switch actuates properly and returns to the "OFF" position when released. Reversing switch action This tool has a reversing switch to change the direction of rotation. Move the revers- ing switch to the left for clockwise rotation or to the right for counterclockwise. CAUTION : 0 Always check the direction of rotation before operation. *Use the reversing switch only after the tool comes to a complete stop. Changing the direction of rotation before the tool stops may damage the tool. Operation The proper fastening torque may differ depending upon the kind or size of the screw, the type of material to be fastened, etc. The relation between fasteningtorque and fastening time is shown in the figures below.

Apply for- ward pressure to the tool to the extent that the bit will not slip off the screw and turn the tool on to start operation. NOTE : 0 Use the proper bit for the head of the screw that you wish to use. Hold the tool pointed straight at the screw. 0 If you fasten the screw for a time longer than shown in the figures above, the screw or 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 verify the adequate fasten- ing time for your screw. When fastening a machine screw in a steel plate, the proper fastening torque can be obtained in an extremely short time (approx. 0.1 -0.2 seconds). Turn the tool off as soon as the impact sound is heard. .When fastening screw M8 (5/16')or smaller, carefully adjust pressure on the trigger switch so that the screw is not damaged. 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. Drive 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 0 Even though the torque coefficient and the class of bolt are the same, the proper fastening torque will differ according to the diameter of the bolt. .Even though the diameters of bolts are the same, the prop...
