004451 Lighting up the front lamp CAUTION: • Do not look in the light or see the source of light directly. Pull the switch trigger to light up the lamp. The lamp keeps on lighting while the switch trigger is being pulled. NOTE: • Use a dry cloth to wipe the dirt off the lens of lamp. Be careful not to scratch the lens of lamp, or it may lower the illumination. 004343 Reversing switch action This tool has a reversing switch to change the direction of rotation. Depress the reversing switch lever from the A side for clockwise rotation or from the B side for counterclockwise rotation. When the reversing switch lever is in the neutral position, the switch trigger cannot be pulled. CAUTION: • 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. • When not operating the tool, always set the reversing switch lever to the neutral position. 1. Reversing switch lever A B 1 1 ASSEMBLY ASSEMBLY CAUTION: • Always be sure that the tool is switched off and the battery cartridge is removed before carrying out any work on the tool. Selecting correct socket Always use the correct size socket for bolts and nuts. An incorrect size socket will result in inaccurate and inconsistent fastening torque and/or damage to the bolt or nut. 004372 Installing or removing socket To install the socket, push it onto the anvil of the tool until it locks into place. To remove the socket, simply pull it off. 1 2 1. Socket 2. Anvil OPERATION OPERATION Standard bolt kind or size of the bolt, the material of the workpiece to be . 140 N m .

Before starting your job, always perform a test M8 M10 0 1.0 2.0 3.0 4.0 5.0(S) Proper fastening torque operation to determine the proper fastening time for your bolt or nut. Especially for the bolt smaller than M8 (5/16”), perform the above test operation to prevent the trouble on socket or bolt, etc. • If the tool is operated continuously until the battery 120 (1224) 100 (1020) 80 Fastening torque (816) 60 M10 (612) 40 (408) M8 20 (204) cartridge has discharged, allow the tool to rest for 15 Fastening time 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. Socket • Failure to use the correct size socket will cause a reduction in the fastening torque. • A worn socket ( wear on the hex end or square end ) 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. 4. The use of the universal joint or the extension bar somewhat reduces the fastening force of the impact wrench. Compensate by fastening for a longer period of time. 5. The manner of holding the tool or the material of driving position to be fastened will affect the torque. 6. Operating the tool at low speed will cause a reduction in the fastening torque. MAINTENANCE CAUTION: • Always be sure that the tool is switched off and the battery cartridge is removed before attempting to perform inspection or maintenance. 001145 Replacing carbon brushes Remove and check the carbon brushes regularly. Replace when they wear down to the limit mark. Keep the carbon brushes clean and free to slip in the holders. Both carbon brushes should be replaced at the same time. Use only identical carbon brushes. 004344 Use a screwdriver to remove the brush holder caps. Take out the worn carbon brushes, insert the new ones and secure the brush holder caps. After replacing brushes, insert the battery cartri...
