Make any needed repairs or replace the cord if necessary. Side Handle For operating convenience, the side handle can be rotated to any position around the tool (360s). NEVER OPERATE TOOL WITHOUT SIDE HANDLE IN PLACE. Depth Rod To adjust the depth rod, loosen the handle and move rod so that the distance between the end of the rod and the end of the bit equals the desired drilling depth (Figure 1). NOTE: Bit must be fully seated in the hammer when measuring. Figure 2 shows how the depth rod contacts the work surface when the desired hole depth is reached. Figure 1 Figure 2 TOOL OPERATION Switch The motor is operated by a variable speed trigger switch which, when depressed, turns the tool on. The variable speed switch allows slow starting when hammering for exact hole positioning or when working with brittle surfaces such as glazed tile. The further the trigger is depressed, the higher the R.P.M. (Revolutions Per Minute) and B.P.M. (Beats Per Minute). Releasing the trigger turns the tool off. Changing Bits The 5013 is designed for the B & D SDS bit system in sizes from 3/16” to 5/8” in diameter. 1. Unplug the unit from power source when inserting bits. 2. Insert the bit with a slight twist. The locking 3. To release bit, pull front end of chuck bac (Figure 3) and pull bit out. takes place automatically durin drilling/hammer drilling. Figure 3 4 Reversing Switch The hammer is equipped with a reversing switch for backing out jammed drill bits or large screws. To operate the hammer in forward, slide the lever in Figure 4 to the right (when viewed from the chuck end) as shown. To operate in reverse, slide the lever to the left. Always be sure that the tool is off and has stopped coasting before changing its direction. Hammer/Drill Selector Lever (Figure 5) Your hammer is equipped with a selector lever to control drilling or hammering action. 1. Turn the tool off and allow it to stop before shifting. 2. To select “hammer drilling”, rotate the selector lever clockwise to the hammer symbol. 3. To select “drilling”, rotate the selector lever counterclockwise to the drill position. Figure 4 SELECTOR LEVER Fiflure 5 DRILL HAMMER Hammer Drilling 1. Position selector lever in the “hammer” position. 2. When drilling, use just enough force on the hammer to keep it from bouncing excessively or “rising” off the bit. Too much force will cause slower drilling speeds, overheating, and a lower drilling rate. 3. Drill straight, keeping the bit at a right angle to the work. Do not exert side pressure on the bit when drilling as this will cause clogging of the bit flutes and a slower drilling speed. 4. When drilling deep holes, if the hammer speed starts to drop off, pull the bit partially out of the hole with the tool still running to help clear debris from the hole. 5. Do not pour water into the hole to settle dust. Water causes clogging of bit flutes which will tend to make the bit bind in the hole. Drilling Always unplug the tool when attaching or changing bits or accessories. 1. Position selector lever in the “drill” position. 2. 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 bits or hole saws. 3. Be sure the material to be drilled is anchored or clamped firmly. If drilling thin material, use a “back-up” block to prevent damage to the material. 4. Always apply pressure in a straight line with the bit. Use enough pressure to keep the bit biting, but do not push hard enough to stall the motor or deflect the bit. 5. Hold tool firmly to control the twisting action. 6. IF TOOL STALLS, it is usually because it is being overloaded. RELEASE TRIGGER IMMEDIATELY, remove bit from work, and determine cause of stalling. Do not click trigger off and on in an attempt to start a stalled tool. This can damage the tool. 7. To minimize stalling or breaking through the material, reduce pressure on hammer and ease the bit through the last fractional part of the hole. 8. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent jamming. 9. With the variable speed feature 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. Maintenance Disconnect tool from the power supply and periodically take the following maintenance action: 1. Clean any dirt build-up out of the air slots in the housing. 2. Check the condition of the power supply cord, plug and extension cord. Repair at once if damaged. 3. Your hammer has a maintenance feature called the “B&D check point system.” When the tool requires motor brush replacement, it will shut down automatically. At this time the tool should be taken to an authorized service center for cleaning, regreasing, and preventative maintenance. Accessories Recommended accessories for use with...
