manual abstract
(See Fig.1) NOTE When the sleeve does not become loose any further, fix the side handle to the sleeve. Then, strike the grip of the side handle to the left in order to loosen the sleeve,while holding the ring by hand. (Fig.2) CAUTION Do not fix the side handle to the ring of the keyless chuck because of a risk that doing so may damage the ring. For Drill chuck with chuck wrench Fit the drill bit into the chuck and use the chuck wrench to secure it, tightening the chuck by each of the three holes in turn. (Fig.3) 6. Selecting the appropriate drill bit . When boring concrete or stone: Use the drill bits for concrete. . When boring metal or plastic: Use an ordinary metalworking drill bit. . When boring wood: Use an ordinary woodworking drill bit. However, when drilling 6.5mm or smaller holes, use a metalworking drill bit. 7. Selecting the driver bit Screw heads or bits will be damaged unless a bit appropriate for the screw diameter is employed to drive in the screws. 8. Confirm the direction of bit rotation (Fig.4) (FDV16VB) The bit rotates clockwise (viewed from the rear) by pushing the R-side of the reverse switch. The L-side of the switch is pushed to turn screws counterclockwise (i.e. to loosen them.) CAUTION . Never change the direction of bit rotation during operation. Turn the power switch OFF before changing the direction of bit rotation; otherwise, the motor will burn. . Always use with clockwise rotation, when using it as an impact drill. 9. IMPACT to ROTATION changeover (Fig.5) The impact drill can be switched from IMPACT (impact plus rotation) to ROTATION (rotation only) by simply sliding the change lever. When boring concrete, stone, tile or similar board materials, slide the change lever right. The drill head impacts against the material while continuing to rotate. When boring metal, wood or plastic, slide the change lever fully to the left. The drill simply rotates as an ordinary electric drill. CAUTION Do not use the impact drill in the IMPACT mode if the material can be bored by rotation only. Such action will not only reduce drill efficiency, but may also damage the drill tip. When changing over, ensure the change lever is slid as far as it will go. HOW TO USE 1. Pressure Drilling will NOT be accelerated by placing heavy pressure on the drill. Such action will only result in a damaged drill bit, decreased drilling efficiency and/or shortened service life of the drill. 2. Using a large diameter drill bit The larger the drill bit diameter, the larger the reactive force on your arm. Be careful not to lose control of the drill because of this reactive force. To maintain firm control, establish a good foothold, hold the drill tightly with both hands, and ensure that the drill is vertical to the material being drilled. 3. When drilling completely through the material When the drill bit bores completely through the material, careless handling often results in a broken, drill bit or damage to the drill body itself due to the sudden movement of the drill. Always be alert and ready to release pushing force when drilling through the material. 4. Speed adjustment and switch operation . FDV16VB English The drill speed can be adjusted from 0 through maximum speed by regulating the trigger squeezing force. The more the trigger is squeezed, the faster the drill rotates. When the trigger is squeezed fully, the speed becomes maximum speed. Turn the adjusting knob clockwise for higher speed and counterclockwise for lower speed. (Rotate the adjusting knob approximately 2-2/3 turns.) (Fig.6) . FDV16T To change speed, slide the shift knob in the appropriate direction, as indicated by the arrow in Fig.7. The mark “H” printed on the shift knob denotes High speed. The mark “L” denotes Low speed. When the shift knob is in High speed position, the rotation speed of the drill bit can be changed in two stages (High speed/Low speed) according to the method of pressing the switch trigger. . FDV16 The maximum speed can be obtained by pulling the trigger switch. . Pull the trigger switch and push the stopper, this keeps the switched in the on position, which is convenient for continuous running. The stopper can be released by pulling the trigger again. CAUTION Drill at a maximum rotation speed when drilling wooden materials. 5. When driving wood screws (FDV16VB) (1) Selecting a suitable driver bit Employ plus-head screws, if possible, since the driver bit easily slips off the heads of minus-head screws. (2) Driving in wood screws . Prior to driving in wood screws, make holes suitable for them on the wooden board. Apply the bit to the screw head grooves and gently drive the screws into the holes. . After rotating the screwdriver at low speed for a while until a wood screw is partly driven into the wood, squeeze the trigger more strongly to obtain optimum driving force. CAUTION . Exercise care in preparing a hole suitable for the wood screws taking the hardness of the wood into consideration. Should the hole be excessively sma...
