SAVE THESE INSTRUCTIONS
Motor
Your DEWALT tool is powered by a DEWALT built motor. Be sure your power supply agrees with the nameplate marking. Voltage decrease of more than 10% will cause loss of power and overheating. All DEWALT tools are factory tested; if this tool does no operate, check the power supply.
Spade Handle Assembly (Fig. 1)
This spade handle can be attached either horizontally or vertically. Place the handle into the locating boss on the back of the drill and assemble with holding knob.
Side Handle (Fig. 1)
WARNING: To reduce the risk of personal injury, ALWAYS operate the tool with the side handle properly installed. 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.
The side handle can be placed in either side of the drill or the top of the drill according to operator preference and available working clearance. The spade handle can be temporarily removed if working clearance at rear of tool is limited. Always replace spade handle when possible.
Switch (Fig. 2)
To start the drill, depress the trigger switch; to stop the drill, release the trigger.
A variable speed trigger switch (A) permits speed control—the farther the trigger is depressed, 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 using abrasive and polishing accessories.
The reversing lever (B) 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. After any reversing operations, return lever to forward position. The locking feature (C) is for use when the drill is mounted in a drill stand or otherwise firmly held…NOT BY HAND.
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.
Be sure to release the switch locking button before disconnecting the plug from the power sup- ply. Failure to do so will cause the tool to start immediately the next time it is plugged in. Damage or injury could result.
Chuck
To insert bit, open chuck jaws by turning collar with fingers and insert shank of bit about 3/4” (19mm) into chuck. Tighten chuck collar by hand. Place chuck key in each of the three holes and tighten in clockwise direction. It’s important to tighten chuck with all three holes.
To release bit, turn chuck key counterclockwise in just one hole, then loosen the chuck by hand.
Chuck Removal (Fig. 3, 4)
1.Place chuck key in chuck as shown in Figure 3. Using a wooden mallet or similar object, strike key sharply in a CLOCKWISE direction. This will loosen screw inside chuck.
2.Open chuck jaws fully. Insert screwdriver into front of chuck between jaws to engage screw head. Remove screw by turning clockwise (left-hand thread).
3.Place key in chuck as shown in Figure 4. Using a wooden mallet or similar object, strike key sharply in a COUNTERCLOCKWISE direction. This will loosen chuck so that it can be unscrewed by hand.
Drilling
1.Use sharp drill bits only. For WOOD, use twist drill bits, spade bits, power auger bits, or hole saws. For METAL, use high-speed steel twist drill bits or hole saws. For MASONRY, such as brick, cement, cinder block etc., use carbide-tipped bits.
2.Be sure the material to be drilled is anchored or clamped firmly. If drilling thin material, use a wood “back-up” block to prevent damage to the material.
3.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.
4.Hold drill firmly to control the twisting action of the drill. Use side handle.
CAUTION: Drill may stall if overloaded causing a sudden twist. Always expect the stall. Grip the drill firmly to control the twisting action and avoid injury.
5.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 OFF AND ON IN AN ATTEMPT TO START A STALLED DRILL
— THIS CAN DAMAGE THE DRILL.
6.To minimize stalling on breaking through the material, reduce pressure on drill and ease the bit through the last fractional part of the hole.
7.Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent jamming.
DRILLING IN WOOD
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 flutes. For larger holes, use spade bits, power auger bits, or hole saws. Work that is likely to splinter should be backed up with a block of wood.
DRILLING IN METALS
Use a cutting lubricant when drilling metals. The exceptions are cast iron and brass which should be drilled dry. The cutting lubricants that work best are sulphurised cutting oil or lard oil; bacon grease will also serve the purpose.
DRILLING IN MASONRY
Use carbide tipped masonry bits at low speeds. Keep even force on the drill but not so much that you crack the brittle materials. A smooth, even flow of dust indicates the proper drilling rate.
MAINTENANCE
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 attach- ments or accessories.
Cleaning
WARNING: Never use solvents or other harsh chemicals for cleaning the non-metallic parts of the tool. These chemicals may weaken the plastic materials used in these parts. Use a cloth dampened only with water and mild soap. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid.
Lubrication
All bearings used are factory lubricated to last the life of the tool. All needle bearings used receive their lubrication from the grease in the gear case. Clean and relubricate gear case yearly or whenever servicing requires the gear case to be removed. Use type and quantity of grease shown on Parts Bulletin packed with your tool.
Gear case is removed by removing the four screws from the front of the tool. If the chuck is too large to permit removal of the two top screws, see instructions for chuck removal.
Motor Brushes
This DEWALT tool uses an advanced brush system which automatically stops the tool when the brushes wear out. This prevents serious damage to the motor.
