Main handle A B D E DWD010 F G DWD014 A B D E F G FIG. 1 C SHOWN IN FORWARD POSITION A C A English English INTENDED USE These heavy-duty V.S.R. drills are designed for professional drilling. DO NOT use under wet conditions or in presence of flammable liquids or gases. These heavy-duty drills are professional power tools. DO NOT let children come into contact with the tool. Supervision is required when inexperienced operators use this tool. ASSEMBLY AND ADJUSTMENTS WARNING: Prior to assembly and adjustment, ALWAYS unplug tool. Forward/Reverse Lever (Fig. 1) The forward/reverse lever (C) is used for withdrawing bits from tight holes and removing screws. It is located above the trigger switch. To reverse the motor, release the trigger switch FIRST and then push the lever to the right (viewed when holding the drill in the operating position) . After any reversing operations, return lever to forward position. OPERATION WARNING: Always observe the safety instructions and applicable regulations. WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect tool from power source before making any adjustments or removing/installing attachments or accessories. WARNING: To reduce the risk of personal injury, ALWAYS ensure workpiece is anchored or clamped firmly. If drilling thin material, use a wood “back-up” block to prevent damage to the material. WARNING: Do not attempt to tighten or loosen drill bits (or any other accessory) by gripping the front part of the chuck and turning the tool on. Damage to the chuck and personal injury may occur. Trigger Switch (Fig. 1) To start the drill, depress the trigger switch; to stop the drill, release the trigger switch. NOTE: Use lower speeds for starting holes without a center punch, drilling in metal or plastics, driving screws or drilling ceramics. Higher speeds are better for drilling wood and composition boards and using abrasive and polishing accessories. VARIABLE SPEED A variable speed trigger switch (A) permits speed control—the farther the trigger is depressed, the higher the speed of the drill. For continuous operation, press and hold the variable speed switch, move the lock-on button (B) up, then release the switch. To stop continuous operation, press the switch briefly and release it. Always switch the tool off when work is finished and before unplugging. Proper Hand Position FIG. 2 (Fig. 2) WARNING: To reduce the risk of serious personal injury, ALWAYS use proper hand position as shown in Figure 2. WARNING: To reduce the risk of serious personal injury, ALWAYS hold securely in anticipation of a sudden reaction. Proper hand position requires one hand under the the the other hand on the main handle (G). Drilling WARNING: To reduce the risk of personal injury, ALWAYS ensure workpiece is anchored or clamped firmly. If drilling thin material, use a wood “back-up” block to prevent damage to the material. 5 1. Use sharp drill bits only. For WOOD, use twist drill bits, spade bits, power auger bits, or hole saws. For METAL, use steel twist drill bits or hole saws. 2. Always apply pressure in a straight line with the bit. Use enough pressure to keep drill biting, but do not push hard enough to stall the motor or deflect the bit. 3. Hold tool firmly with both hands to control the twisting action of the drill. 4. IF DRILL STALLS, it is usually because it is being overloaded or improperly used. RELEASE TRIGGER IMMEDIATELY, remove drill bit from work, and determine cause of stalling. DO NOT CLICK TRIGGER ON AND OFF IN AN ATTEMPT TO START A STALLED DRILL — THIS CAN DAMAGE THE DRILL. 5. To minimize stalling or breaking through the material, reduce pressure on drill and ease the bit through the last fractional part of the hole. 6. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent jamming. 7. With variable speed drills there is no need to center punch the point to be drilled. Use a slow speed to start the hole and accelerate by squeezing the trigger harder when the hole is deep enough to drill without the bit skipping out. DRILLING IN METAL Start drilling with slow speed and increase to full power while applying firm pressure on the tool. A smooth even flow of metal chips indicates the proper drilling rate. Use a cutting lubricant when drilling metals. The exceptions are cast iron and brass which should be drilled dry. NOTE: Large [5/16" (8 mm) to 1/2" (13 mm)] holes in made easier if a pilot hole [5/32" (4 mm) to 3/first. DRILLING IN WOOD Start drilling with slow speed and increase to full power while applying firm pressure on the tool. Holes in wood can be made with the same twist drills used for metal. These bits may overheat unless pulled out frequently to clear chips from the flute...
