[. . . ] Before using battery cartridge, read all instructions and cautionary markings on (1) battery charger, (2) battery, and (3) product using battery. 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 short the battery cartridge: (1) Do not touch the terminals with any conductive material. [. . . ] ⷠWhen not operating the tool, always set the reversing switch lever to the neutral position. Always stop tool operation and charge the battery cartridge when you notice less tool power. Always be sure that the tool is switched off and the battery cartridge is removed before adjusting or checking function on the tool. To change the speed, first switch off the tool and then slide the speed change lever to the "2" side for high speed or "1" side for low speed. Be sure that the speed change lever is set to the correct position before operation. cAUTION: · Always set the speed change lever fully to the correct position. If you operate the tool with the speed change lever positioned halfway between the "1" side and "2" side, the tool may be damaged. 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. Place the point of the driver bit in the screw head and apply pressure to the tool. cAUTION: · Make sure that the driver bit is inserted straight in the screw head, or the screw and/or bit may be damaged. nOTE: · When driving wood screws, predrill pilot holes to make driving easier and to prevent splitting of the workpiece. Nominal diameter of wood Recommended size of pilot screw (mm) hole (mm) 3. The fastening torque can be adjusted in 17 steps by turning the adjusting ring so that its graduations are aligned with the pointer on the tool body. The fastening torque is minimum when the number 1 is aligned with the pointer, and maximum when the marking is aligned with the pointer. The clutch will slip at various torque levels when set at the number 1 to 16. Before actual operation, drive a trial screw into your material or a piece of duplicate material to determine which torque level is required for a particular application. Always be sure that the tool is switched off and the battery cartridge is removed before carrying out any work on the tool. Fit the bit holder into the protrusion at the tool foot on either right or left side and secure it with a screw. First, turn the adjusting ring so that the pointer points to the marking. Drilling in wood When drilling in wood, the best results are obtained with wood drills equipped with a guide screw. The guide screw makes drilling easier by pulling the bit into the workpiece.
