Charging will begin after the battery cartridge cools, The battery cartridge will cool faster if you remove the battery cartridge from the fast charger. If the charging light flashes alternately in green and red colour and a tone sounds 'beep, beep, beep, ..."for about 20 seconds, 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 twg battery cartridges. allow 15 minutes between chargings on the fast charger. Installing or removing driver bit or drill bit CAUTION: Always be sure that the tool is switched off and the battery cartridge is removed before installing or removing the bit. Hold the ring and turn the sleeve counter- clockwise to open the chuck jaws. Place the bit in the chuck as far as it will go. Hold the ring firmly and turn the sleeve clockwise to tighten the chuck. To remove the bit, hold the ring and turn the sleeve counterclockwise. Sleeve k Switch action Tool speed is increased by increasing pres- sure on the trigger. To start the tool, simply pull the trigger. Release the trigger to stop. CAUTION: Before inserting the battery cartridge into the tool, always check to see that the switch trigger actuates properly and returns to the “OFF” position when released. Reversing switch action This tool has a reversing switch to change the direction of rotation. Slide the revers- ing switch to the left for clockwise rota- tion or to the right for counterclockwise. CAUTION : Always check the direction of rotation before operation. *Move the reversing switch only after the tool comes to a complete stop. Changing the direction of rotation before the tool stops may damage the tool. Speed change To change the speed, slide the speed change lever to the "H" side for high speed or "L" side for low speed. To slide the speed change lever easily, pull the trigger slightly while pushing the speed change lever. Be sure that the speed change lever is set to the correct position before operation. Use the right speed for your job. CAUTIO N : Always set the speed change lever fully into the correct position. If you operate the tool with the speed change lever positioned halfway between the "H" side and "L" side, the tool may be damaged. Adjusting fastening torque The fastening torque can be adjusted in six stages by turning the adjusting ring so that the pointer on the adjusting ring points to a number on the tool body. The fastening torque is minimum when the pointer points to the number 1 and maximum when it points to the -\-marking. The clutch will slip at varying torque levels when the pointer is set at the numbers 1 to 5. The clutch is designed not to slip at the -8- marking. 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. NOTE : The adjusting ring cannot be locked with the pointer positioned half-way between the numbers. Screwdriving operation Place the point of the driver bit in the screw head and apply pressure to the tool. Start the tool slowly and then increase the speed gradually. Release the trigger as soon as the clutch cuts in. When driving wood screws, predrill pilot holes to make driving easier and to pre- vent splitting of the workpiece. See the chart.

Then proceed as follows. 0 Drilling in wood When drilling in wood, 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. 0 Drilling in metal To prevent the bit from slipping when starting a hole, make an indentation with a center- punch and hammer at the point to be drilled place the point of the bit in the indenta- tion and start drilling. Use a cutting lubricant when drilling metals. The exceptions are iron and brass which should be drilled dry. CAUTION: *Pressing excessively on the tool will not speed up the drilling. 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 force exerted on the tool/bit at the time of hole breakthrough. Hold the tool firmly and exert care when the bit begins to break through the workpiece. *A stuck bit can be removed simply by setting the reversing switch to reverse rotation in order to back out. However, the tool may...
