User manual RYOBI 12V IMPACT DRIVER KIT BID1211

[. . . ] OPERATOR'S MANUAL CORDLESS IMPACT DRIVER MODEL NO. BID-1211 THANK YOU FOR BUYING A RYOBI CORDLESS IMPACT DRIVER. Your new cordless impact driver has been engineered and manufactured to Ryobi's high standard for dependability, ease of operation, and operator safety. Properly cared for, it will give you years of rugged, trouble-free performance. CAUTION: Carefully read through this entire operator's manual before using your new cordless impact driver. Pay close attention to the Rules for Safe Operation, Warnings, and Cautions. [. . . ] When the reversing switch is pushed in from the side of "R", the bit rotates clockwise when viewed from the handle end of the tool. When the reversing switch is pushed in from the side of "L", the bit rotates counterclockwise. The trigger can be locked by positioning the reversing switch in the middle. Lock the trigger whenever the tool is not in use. DISPOSAL OF THE EXHAUSTED BATTERY Recycle Ni-Cd batteries. Take the battery to the shop from which it was purchased as soon as the post-charging battery life becomes too short for practical use. Please do not discard the exhausted battery. Page 2 FASTENING TORQUE The proper fastening torque differs depending on the kind and size of the screw and the type of the material to be fastened. When fastening a screw smaller than M6, check the fastening torque and fastening time. 5) X-axis (abscissa) : Fastening time (Second) Y-axis (ordinate) : Fastening torque (Nm) Carefully adjust the fastening torque by controlling the trigger-squeezing force so that the screw is not damaged. To avoid the reduction of the fastening torque, keep the battery properly charged. The fastening torque is affected by the following factors. VOLTAGE When the battery is almost discharged, the voltage will drop and the fastening torque will be reduced. FASTENING TIME If the fastening time is prolonged, the fastening torque will be increased. However, if the fastening torque reaches the maximum, it will not increase any more. SCREW AND BOLT Even though the torque coefficient and class of the screws or bolts are the same, the fastening torque will differ according to their diameters. Generally, the larger the diameter, the higher the fastening torque. On the other hand, even though the diameter of the bolts or screws are the same, the fastening torque will differ according to the torque coefficient, their class and their length. BIT Failure to use the correct size bit causes a reduction in the fastening torque. SWITCH The rotation speed and the fastening torque can be adjusted by controlling the trigger-squeezing force. The lower the rotation speed, the lower the fastening torque. LED LED will be lighted when depressing switch trigger. WARNING!Do not incinerate the battery even if it is severely damaged or is completely worn out. The battery and charger are specifically designed for use in conjunction with one another. [. . . ] 2. Avoid storing the battery in a container with other metal objects such as nails, coins, etc. 3. Do not expose the battery to water or rain. Do not store the tool and battery in locations where the temperature may reach or exceed 50°C. Page 3 OPERATING GREEN LIGHT "ON" INDICATES FULLY CHARGED BATTERY CHARGER NEVER COVER THE AIR VENTS SINCE THEY MUST ALWAYS BE OPEN FOR PROPER MOTOR COOLING. 1. Hold the tool firmly and place the tip of the bit in the screw head so that it is perpendicular to the screw head. [. . . ]
