Rotate it sufficiently for the chuck to open far enough to accept the bit or accessory. 3. Fully insert the bit or accessory into the chuck (1) and tighten securely by rotating the chuck clockwise with one hand whilst holding the spindle lock button (9) pressed with the other hand. WARNING. Do not attempt to tighten the chuck by gripping the front part and turning the drill on. Damage to the tool and personal injury may result. Be sure to tighten the chuck with the spindle lock button held pressed to achieve maximum tightness. Operation Starting and stopping Operational controls 1. Ensure that the tool is in good condition. 2. Plug the cordset into the mains socket. 3. Depress the trigger switch (7) to start the drill and release the trigger when you wish to stop. 4. Press the lock-on button (5) whilst the trigger is depressed if you require continuous operation. To disengage the lock-on switch, press the trigger then release it. Variable speed trigger switch 1. You can adjust the speed of the drill between zero and maximum by varying the pressure on the trigger. The harder you press on the trigger the faster the drill will operate. Speed adjustment 1. You can change the maximum speed setting by turning the speed dial (8) located on the trigger switch (7). To increase the speed turn the dial so that the thickest part of the line is above the arrow on the trigger, as shown in Fig. 1. Reversing the direction of rotation 1. The forward/reverse switch (6) protrudes from one side of the drill to the other. 2. The arrow head symbol on each side of the switch indicates the direction of drilling when the switch is pushed from that side. The forward direction is selected when the arrow head symbol points to the front of the drill. The reverse direction is selected when the arrow head symbol points to the rear of the drill. CAUTION. Any attempt to reverse the direction of rotation whilst the drill is turning is likely to permanently damage the motor, gearing or both. Drilling/hammer mode selector You can use the drill for both hammer action and normal drilling. 1. Use the drilling/hammer mode selector (4) to select hammer or drill action. The type of drilling selected is indicated by the symbol on each side of the drill. 2. Push the selector to for hammer action. 3. Push the selector to for drill action. CAUTION. Change the mode of action only when the drill has come to a complete standstill. NOTE. Hammer action drilling should only be preformed in the forward direction. Fig. 1 9 Chuck replacement Chuck removal Always wear eye protection. Tighten the chuck around the shorter end of a hex key (not supplied) of 5mm or greater size. Using a wooden mallet or similar object, strike the longer end in the clockwise direction. This will loosen the screw inside the chuck. 1. Open chuck jaws fully. 2. Insert a phillips head screwdriver into front of chuck between jaws to engage screw head. Remove screw by turning clockwise. 3. Place the hex key in chuck and tighten. Using a wooden mallet or similar object, strike key sharply in the anti-clockwise direction. This will loosen the chuck so that it can be unscrewed by hand. Chuck installation 1. Screw the chuck on by hand as far as it will go and insert screw (LH thread). 2. Tighten the chuck around the shorter end of a 1/4”or large hex key (not supplied) strike the longer end in the clockwise direction with a wooden mallet. 3. Remove the hex key and open the jaws fully. Tighten the screw in the centre of the chuck firmly. Hints for use Note. When drilling into masonry the drilling rate is fast and burnout of the tip will occur if the drill bit is not constantly cleared. • Use only correctly sharpened drill bits, which are suitable for the material being drilled. • To drill hard materials, firm pressure is required on the power tool. However, excessive pressure does not improve performance and places unnecessary pressure on the tool and its bit. • When screw driving always use a pilot hole and set the speed dial to low. Press firmly on the screw head and pull the trigger gradually increasing the speed. It is always wiser to test the screw driving on a scrap piece of the same material you are using. • Larger diameter holes in hard wood, steel and concrete have to be drilled at slower speeds. However, the motor must not be struggling with the operation. If the motor is struggling DO NOT continue working, pull the drill clear of the workpiece and run it on fast speed for a minute or so allowing the motor time to cool down before you continue with the task. If the job is too hard for the drill do not continue otherwise you could permanently damage the motor. • Concrete drilling should be carried out on the highest speed. DO NOT overload motor when drilling concrete. DO NOT use too much pressure as the hammer action relies on the drill bit being able to move back and forward in the hole being drilled. Always clear the flutes of the drill bit by removing it from the hole regularly. Wood...
