Resumen del manual
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. 005710 005710 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: 1. Lamp • 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. 005749 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. 1 1. Reversing switch lever 1 A B ASSEMBLY 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 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. 003920 003920 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.

Before starting your job, always perform a test operation to determine the proper fastening time for your bolt or nut. Especially for the bolt smaller than M8 (5/ M10 (3/8”) 80 (58) (72) Fastening torque 16”), perform the above test operation to prevent the trouble on socket or bolt, etc. • If the tool is operated continuously until the battery cartridge has discharged, allow the tool to rest for 15 Proper fastening torque 60 M10 (3/8”) (43) M8 (5/16”) 40 (29) M8 (5/16”) (14) 0 1.0 2.0 3.0 4.0 5.0 (S) minutes before proceeding with a fresh battery. Fastening time 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 an...
