Important Safety Instructions for All Tools

WARNING: When using electric tools, basic safety precautions should always be followed to reduce risk of fire, electric shock, and personal injury, including the following:

SAVE THESE INSTRUCTIONS

WORK AREA

•Keep your work area clean and well lit. Cluttered benches and dark areas invite acci- dents.

•Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.

•Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

•Double insulated tools are equipped with a polarized plug (one blade is wider than the other.) This plug will fit in a polarized outlet only one way. If the plug does not fit

fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in any way. Double insulation eliminates the need for the three wire grounded power cord and grounded power supply system.

•Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is grounded.

•Don’t expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

•Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace dam- aged cords immediately. Damaged cords increase the risk of electric shock.

•When operating a power tool outside, use an outdoor extension cord marked “W-A”

or “W.” These cords are rated for outdoor use and reduce the risk of electric shock.

PERSONAL SAFETY

•Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use tool while tired or under the influence of drugs, alcohol, or medica- tion. A moment of inattention while operating power tools may result in serious personal injury,

•Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing , and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.

•Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with your finger on the switch or plugging in tools that have the switch on invites accidents.

•Remove adjusting keys or wrenches before turning the tool on. A wrench or a key that is left attached to a rotating part of the tool may result in personal injury.

•Do not overreach. Keep proper footing and balance at all times. Proper footing and bal- ance enables better control of the tool in unexpected situations.

•Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions.

TOOL USE AND CARE

•Use clamps or other practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control.

•Do not force tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed.

•Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled with the switch is dangerous and must be repaired.

•Disconnect the plug from the power source before making any adjustments, changing accessories, or storing the tool. Such preventative safety measures reduce the risk of starting the tool accidentally.

•Store idle tools out of reach of children and other untrained persons. Tools are dan- gerous in the hands of untrained users.

•Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools, with sharp cutting edges are less likely to bind and are easier to control.

•Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tools operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools.

•Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool, may become hazardous when used on anoth- er tool.

SERVICE

•Tool service must be performed only by qualified repair personnel. Service or mainte- nance performed by unqualified personnel could result in a risk of injury.

•When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance Instructions may create a risk of electric shock or injury.

Additional Specific Safety Rules for Rotary Hammers

•Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator.

•Wear ear protectors when hammering for an extended period of time. Temporary hear- ing loss or serious ear drum damage may result from high sound levels generated by ham- mer drilling.

•Wear safety goggles or other eye protection. Hammering and drilling operations cause chips to fly. Flying particles can cause permanent eye damage.

•Always use the side handle supplied with the tool. Keep a firm grip on the tool at all times. Do not attempt to operate this tool without holding it with both hands.

•Hammer bits and tools get hot during operation. Wear gloves when touching them.

• CAUTION:DO NOT TOUCH ANY METAL PARTS OF THE TOOL when drilling or dri- ving into walls, floors or wherever live electrical wires may be encountered! Hold the tool only by insulated grasping surfaces to prevent electric shock if you drill or drive into a live wire.

WARNING: Use of this tool can generate dust containing chemicals known to cause can- cer, birth defects or other reproductive harm. Use appropriate respiratory protection.

Side Handle (Fig. 1)

CAUTION: Always use side handle (A) and hold rotary hammer with both hands.. It clamps to the front of the gear case as shown and can be rotated 360˚ to permit right or left hand use. The grip may be unscrewed and retightened to relocate the handle in the desired location.

Switch (Fig. 1)

The variable speed trigger switch (B) permits speed control. The farther the trigger switch is depressed, the higher the speed of the rotary hammer.

NOTE: Use lower speeds for starting holes without a center punch, drilling in metal, plastics or ceramics, or driving screws. Higher speeds are better for drilling in wood and composition board and for using abrasive and polishing accessories.

Hammer/Drill Selector (Fig. 2)

To switch the tool from the drilling mode to the rotary hammer mode (or vice-versa) rotate the dial (A) on the applicable symbol shown above.

NOTE: The selector must be in either drill, or rotary hammer mode at all times.

SDS Chuck

To insert bit, insert shank of bit about 3/4” into chuck. Turn the bit slightly until it clicks into position. The bit will be securely held.

To release bit, pull the collar back and remove the bit.

Operation

DRILLING

1.Always unplug the drill when attaching or changing bits or accessories.

2.Always use sharp drill bits. For WOOD, use twist drill bits, spade bits, power auger bits, or hole saws. For METAL, use steel twist drill bits or hole saws. For MASONRY, such as brick, cement, cinder block, etc., use carbide-tipped bits rated for percussion drilling.

3.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.

4.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.

5.Hold tool firmly to control the twisting action of the drill.

6.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.

7.To minimize stalling or breaking through the material, reduce pressure on drill 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 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. The cutting lubricants that work best are sulphurized cutting oil or lard oil; bacon-grease will also serve the purpose.

NOTE: Large (5/16” to 1/2”)(7.6 mm to 13 mm) holes in steel can be made easier if a pilot hole (5/32” to 3/16”) (3.8 mm to 5 mm) is drilled first.
