Due to a lockout mechanism, the control switch can only be adjusted when the ON/OFF switch is not depressed. Always allow the motor to come to a complete stop before using the control switch. Fig. 6 1 3 2 Forward (clockwise) rotation, push the control switch to the left position (1). Check the direction of rotation before use. Reverse (counterclockwise) rotation, push the control switch to the right position (2). Check direction of rotation before use. Locking the trigger, push the control switch to center position (3). The trigger will not work while the control switch is in the center locked position. Always lock the trigger or remove the battery pack before performing maintenance, changing accessories, storing the tool and any time the tool is not in use. Starting, Stopping & Controlling Speed 1. To start the tool, pull the trigger. 2. To stop the tool, release the trigger and an electric brake stops the tool instantly. All models feature variable speed control. To vary the speed, simply increase or decrease pressure on the trigger. The further the trigger is pulled, the greater the speed. Drilling Set the clutch adjusting ring to the drill position (Cat. No. 0514-20 only). Place the bit on the work surface and apply firm pressure before starting. Too much pressure will slow the bit and reduce drilling efficiency. Too little pressure will cause the bit to slide over the work area and dull the point of the bit. If the tool begins to stall, reduce pressure slightly to allow the bit to regain speed. If the bit binds, reverse the motor to free the bit from the workpiece. APPLICATIONS To reduce the risk of electric shock, check work area for hidden pipes and wires before drilling or driving screws. WARNING! Drilling in Wood, Composition Materials and Plastic When drilling in wood, composition materials and plastic, start the drill slowly, gradually increasing speed as you drill. When drilling into wood, use wood augers or twist drill bits. Always use sharp bits. When using twist drill bits, pull the bit out of the hole frequently to clear chips from the bit flutes. To reduce the chance of splintering, back work with a piece of scrap wood. Select low speeds for plastics with a low melting point. Drilling in Metal When drilling in metal, use high speed steel twist drills or hole saws. Use a center punch to start the hole. Lubricate drill bits with cutting oil when drilling in iron or steel. Use a coolant when drilling in nonferrous metals such as copper, brass or aluminum. Back the material to prevent binding and distortion on breakthrough. Drilling in Masonry When drilling in masonry, select the hammer-drill operating mode (Cat. No. 0514-20 only). Use high speed carbide-tipped bits. Drilling soft masonry materials such as cinder block requires little pressure. Hard materials like concrete require more pressure. A smooth, even flow of dust indicates the proper drilling rate. Do not let the bit spin in the hole without cutting. Do not use water to settle dust or to cool bit. Both actions will damage the carbide. Driving Screws and Nut Running Drill a pilot hole when driving screws into thick or hard materials. Set the clutch adjusting ring to the proper position and set the speed to low. Use the proper style and size screwdriver bit for the type of screw you are using. With the screwdriver bit in the screw, place the tip of the screw on the workpiece and apply firm pressure before pulling the trigger. Screws can be removed by reversing the motor. Overloading Continuous overloading may cause permanent damage to tool or battery pack. page 6 MAINTENANCE To reduce the risk of personal injury always unplug the charger and remove the battery pack from the charger or tool before performing any maintenance. Never disassemble the tool, battery pack or charger. Contact a MILWAUKEE service facility for ALL repairs. WARNING! Keep your tool, battery pack and charger in good repair by adopting a regular maintenance program. After six months to one year, depending on use, return the tool, battery pack and charger to a MILWAUKEE service facility for: • Lubrication • Brush inspection and replacement • Mechanical inspection and cleaning (gears, spindles, bearings, housing, etc.) • Electrical inspection (battery pack, charger, motor) • Testing to assure proper mechanical and electrical operation Maintaining Tool If the tool does not start or operate at full power with a fully charged battery pack, clean the contacts on the battery pack. If the tool still does not work properly, return the tool, charger and battery pack to a MILWAUKEE service facility for repairs. Maintaining Battery Pack MILWAUKEENickel-Cadmium battery packs will operate for many years and/or hundreds of cycles when they are maintained and used according to these instructions. A battery pack that is stored for six months without being used will discharge itself. Batteries discharge at a rate of about 1% per day. Charge the battery every six months even if it is un...
