[. . . ] A battery short can cause a large current flow, overheating, possible burns and even a breakdown. Do not store the tool and battery cartridge in locations where the temperature may reach or exceed 50°C (122°F). Do not incinerate the battery cartridge even if it is severely damaged or is completely worn out. the battery cartridge can explode in a fire. [. . . ] Do not operate charger if it has received a sharp blow, been dropped, or otherwise damaged in any way; take it to a qualified serviceman. Do not disassemble charger or battery cartridge; take it to a qualified serviceman when service or repair is required. Incorrect reassembly may result in a risk of electric shock or fire. Be aware that this tool is always in an operating condition, because it does not have to be plugged into an electrical outlet. Check the socket carefully for wear, cracks or damage before installation. Be sure no one is below when using the tool in high locations. The proper fastening torque may differ depending upon the kind or size of the bolt. When driving into walls, floors or wherever "live" electrical wires may be encountered, DO NOT TOUCH ANY METAL PARTS OF THE TOOL!Hold the tool only by the insulated grasping surfaces to prevent electric shock if you drive into a "live" wire. Always switch off the tool before insertion or removal of the battery cartridge. ⷠTo remove the battery cartridge, withdraw it from the tool while pressing the buttons on both sides of the cartridge. ⷠIf the charging light flashes alternately in green and red color, a problem exists and charging is not possible. The terminals on the charger or battery cartridge are clogged with dust or the battery cartridge is worn out or damaged. ⷠIf you wish to charge two battery cartridges, allow 15 minutes between chargings on the fast charger. If you leave the battery cartridge in the charger to prevent spontaneous discharging after full charge, the charger will switch into its "trickle charge (maintenance charge)" mode and keep the battery cartridge fresh and fully charged. Always stop tool operation and charge the battery cartridge when you notice less tool power. Charge the Nickel Metal Hydride battery cartridge when you do not use it for more than six months. the fastening torque is affected by a wide variety of factors including the following. After fastening, always check the torque with a torque wrench. When the battery cartridge is discharged almost completely, voltage will drop and the fastening torque will be reduced. Failure to use the correct size socket will cause a reduction in the fastening torque. 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. [. . . ] CAUTION: Always be sure that the tool is switched off and the battery cartridge is removed before carrying out any work on the tool. To maintain product safety and reliability, repairs, maintenance or adjustment should be carried out by a Makita Authorized Service Center. Always check the direction of rotation before operation. ⷠUse the reversing switch only after the tool comes to a complete stop. [. . . ]
