This takes up the reaction of the stall and allows you to keep the drill under control. The speed control senses your release of the trigger and resets the motor to run again. Figure 4 shows the instruction label (G) mounted behind the indicator light (E). There are three alert modes. 1. Check Mode: Light will flash once each time the trigger is depressed to indicate everything is functioning satisfactorily. Be sure to check for single flash periodically while using. If there is no flash, the tool should be returned to a DEWALT authorized service center for repair. 2. Engaged Mode: Should a stall condition still exist, the electronics will shut down the tool and the light will be steady on. When the unit is running in normal mode, there will be no light. 3. Alert Mode: A series of continual flashes as the trigger is pulled indicates that the electronics are no longer functioning. The tool may still be able to function without the benefit of AntiLock Control but should be serviced as soon as possible. Motor Brushes DEWALT uses an advanced brush system which automatically stops the drill when the brushes wear out. This prevents serious damage to the motor. Switch (Fig. 1) To start drill, depress trigger switch; to stop the drill, release trigger. To lock trigger in the on position for continuous operation, depress trigger and push up locking button (B), then gently release the trigger. To release the locking mechanism, depress the trigger fully, then release it. Before using the tool each time, be sure that the locking button release mechanism is working freely. Do not lock the switch on when drilling by hand so that you can instantly release the trigger switch if the bit binds in the hole. The locking button is for use only when the drill is mounted in a drill press stand or otherwise held stationary. Be sure to release the locking button before disconnecting the plug from the power supply. Failure to do so will cause the tool to start immediately the next time it is plugged in. Damage or injury could result. VARIABLE SPEED TRIGGER SWITCH This switch permits speed control: the farther the trigger is de pressed, the higher the speed of the drill. 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 for using abrasive and polishing accessories. REVERSING LEVER The reversing lever changes the direction of rotation of the drill and is used when backing out screws and jammed drill bits. To operate the tool in reverse, release the trigger switch and push the lever to the left (when viewed from the chuck end) as shown in Figure 2. To operate the drill in forward for drilling holes or driving screws (as well as when using other accessories) release the trigger switch and push the lever to the right (when viewed from the chuck end). Return the reversing lever to the forward position after all operations in reverse are completed. SWITCH LOCK-ON Your drill is equipped with a switch lock-on feature. If you wish to disable this feature, take your tool to any authorized service center.The service center can provide a lock-out key (D) to prevent the unit from being locked in the on position (Fig. 3). OPERATION 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. Side Handle WARNING: To reduce the risk of personal injury, ALWAYS operate the tool with the side handle properly installed and tightened. Failure to do so may result in the side handle slipping during tool operation and subsequent loss of control. Hold tool with both hands to maximize control. A side handle may be supplied with your drill. Side handles are included with these drills: DW231, DW235-220, DW235G, DW236, DW237, DW238, DW239, DW245, DW246, DW248, DW249. The side handle clamps to the front of the gear case and can be rotated 360 degrees to permit right- or left-hand use. Drilling 1. Use sharp drill bits only. For WOOD, use the low speed setting and twist drill bits, spade bits, power auger bits, or hole saws. For METAL, use the low speed setting and steel twist drill bits or hole saws. For MASONRY, such as brick, cement, cinder block, etc., use carbide-tipped bits rated for percussion drilling. Use low speed for bits greater than 3/8" (10 mm). 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. WARNING: Drill may stall if overloaded causing a sudden twist. Always expect the stall. Grip the dr...
