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. A charger that may be suitable for one type of battery may create a risk of fire when used with another battery. [. . . ] 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. 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 side 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. Insert the battery cartridge into charger until it stops adjusting to the guide of charger. Terminal cover of charger can be opened with inserting and closed with pulling out the battery cartridge. When the battery cartridge is inserted, the charging light color will change from green to red and charging will begin. The charging light will keep lighting up lit steadily during charging. One red charging light indicates charged condition in 0 - 80% and two red ones indicates 80 - 100%. With finish of charge, the charging lights will change from two red ones to two green ones. CAUTION: Always be sure that the tool is switched off and the battery cartridge is removed before adjusting or checking function on the tool. If you leave the battery cartridge in the charger after the charging cycle is complete, the charger will switch into its "trickle charge (maintenance charge)" mode which will last approximately 24 hours. Never use it for other purposes or for other manufacturer's batteries. ⷠWhen you charge a new battery cartridge or a battery cartridge which has not been used for a long period of time, it may not accept a full charge. You can recharge the battery cartridge fully after discharging it completely and recharging a couple of times. ⷠIf you charge a battery cartridge from a just operated tool or battery cartridge which has been left in a location exposed to direct sunlight for a long time, the charging light may flash in red color. 70°C, two charging lights may flash in red color, and when approx. [. . . ] CAUTION: Always be sure that the tool is switched off and the battery cartridge is removed before attempting to perform inspection or maintenance. CAUTION: Never use "rotation with hammering" when the drill chuck assembly is installed on the tool. In fact, this excessive pressure will only serve to damage the tip of your bit, decrease the tool performance and shorten the service life of the tool. there is a tremendous twisting force exerted on the tool/bit at the time of hole breakthrough.
