3. Charge the battery cartridge with room temperature at 10°C - 40°C (50°F - 104°F). Let a hot battery cartridge cool down before charging it. 4. Charge the Nickel Metal Hydride battery cartridge when you do not use it for more than six months. Refresh charging Refreshing adapter (optional accessory) can refresh an inactive battery cartridge. Refresh charging should be done once a week. When you charge a new battery cartridge or a battery cartridge that has not been used for a long time, it may not 1 1 Switch trigger ASSEMBLY accept a full charge. In this case, refresh charging must be done. The battery cartridge my decrease the tool performance, because the chemical substance of the battery cartridge is inactive. 002319 Switch action CAUTION: • Before inserting the battery cartridge into the tool, always check to see that the switch trigger actuates properly and returns to the “OFF” position when released. To start the tool, simply pull the switch trigger. Tool speed is increased by increasing pressure on the switch trigger. Release the switch trigger to stop. Electric brake This tool is equipped with an electric brake. If the tool consistently fails to quickly stop after switch trigger release, have tool serviced at a Makita service center. 002326 Reversing switch action 1. Reversing switch lever 1 A B 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. 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 Selecting correct socket 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 002334 1. Socket 2. Anvil OPERATION N.m (ft.lbs) Standard bolt M16 (5/8”) 140 (100) CAUTION: • Always insert the battery cartridge all the way until it locks in place. If you can see the red part on the upper side of the button, it is not locked completely. Insert it fully until the red part cannot be seen. If not, it may accidentally fall out of the tool, causing injury to you or someone around you. 002365 The proper fastening torque may differ depending upon the kind or size of the bolt, the material of the workpiece to be 120 (86) M16 (5/8”) 100 Proper fastening torque fastened, etc. The relation between fastening torque and fas tening time is shown in the figures.

Before starting your job, always perform a test 0 12345(S) Fastening time 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. • • 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...
