Due to our continuing programme of research and development, the specifications herein are subject to change without notice. ⷠNote: Specifications may differ from country to country. Stay alert, watch what you are doing and use common sense when operating a power tool. [. . . ] If electrolyte gets into your eyes, rinse them out with clear water and seek medical attention right away. Do not short the battery cartridge: (1) Do not touch the terminals with any conductive material. 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). Always switch off the tool before insertion or removal of the battery cartridge. To remove the battery cartridge, withdraw it from the tool while sliding the button on the front of the cartridge. To insert the battery cartridge, align the tongue on the battery cartridge with the groove in the housing and slip it into place. Always insert it all the way until it locks in place with a little click. If you can see the red part on the upper side of the button, it is not locked completely. If not, it may accidentally fall out of the tool, causing injury to you or someone around you. If the cartridge does not slide in easily, it is not being inserted correctly. Press the shaft lock to prevent spindle rotation when installing or removing accessories. When the battery cartridge is inserted on the tool with the slide switch positioned in the "O (OFF)" position, the indication lamp flickers quickly for approximately one second. - If the tool continues to be overloaded and the indication lamp continues to light up for approximately two seconds, the tool stops. - In this case, to start the tool again, move the slide switch to the "O (OFF)" position once and then to the "I (ON)" position. - Battery cartridge replacing signal - When the remaining battery capacity gets small, the indicator lamp lights up during operation earlier than enough capacity battery use. - Accidental re-start preventive function - Even if the battery cartridge is inserted on the tool with the slide switch in the "I (ON)" position, the tool does not start. At this time, the lamp flickers slowly and this shows that the accidental re-start preventive function is at work. - To start the tool, first slide the slide switch toward the "O (OFF)" position and then slide it toward the "I (ON)" position. CAUTION: Before inserting the battery cartridge into the tool, always check to see that the slide switch actuates properly and returns to the "OFF" position when the rear of the slide switch is depressed. ⷠSwitch can be locked in "ON" position for ease of operator comfort during extended use. For continuous operation, press the front of the slide switch to lock it. [. . . ] ⷠALWAYS use guard with wire wheel brushes, assuring diameter of wheel fits inside guard. Wheel can shatter during use and guard helps to reduce chances of personal injury. Remove the battery cartridge from the tool and place it upside down allowing easy access to spindle. CAUTION: Always be sure that the tool is switched off and the battery cartridge is removed before attempting to perform inspection or maintenance. [. . . ]
