[. . . ] 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. Use battery operated tool only with specifically designated battery pack. Failure to follow all instructions listed below, may result in electric shock, fire and/or serious personal injury. [. . . ] It may result in a risk of overheating, possible burns and even an explosion. If electrolyte gets into your eyes, rinse them out with clear water and seek medical attention right away. Do not charge Battery Cartridge when temperature is BELOW 10°C (50°F) or ABOVE 40°C (104°F). Do not attempt to use a step-up transformer, an engine generator or DC power receptacle. 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). Do not incinerate the Battery Cartridge even if it is severely damaged or is completely worn out. 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. CAUTION: Always be sure that the tool is switched off and the battery cartridge is removed before adjusting or checking function on the tool. 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. 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. [. . . ] If the shoe is held away from the workpiece during operation, strong vibration and/or twisting will be produced, causing the blade to snap dangerously. Always wear gloves to protect your hands from hot flying chips when cutting metal. Be sure to always wear suitable eye protection which conforms with current national standards. If the tool is operated continuously until the battery cartridge has discharged, allow the tool to rest for 15 minutes before proceeding with a fresh battery. [. . . ]
