General Safety Rules
WARNING! READ AND UNDERSTAND ALL INSTRUCTIONS. Failure to follow all instructions listed below may result in electric shock, fire and/or serious personal
injury.
SAVE THESE INSTRUCTIONS
WORK AREA
•Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.
•Do not operate power tools in explosive atmospheres, such as in the presence of flam- mable 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
•Grounded tools must be plugged into an outlet properly installed and grounded in accordance with all codes and ordinances. Never remove the grounding prong or modify the plug in any way. Do not use any adapter plugs. Check with a qualified elec- trician if you are in doubt as to whether the outlet is properly grounded. If the tools should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user. Applicable only to Class I (grounded) tools.
•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 polar-
ized 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. Applicable only to Class II (double insulated) tools.
•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 damaged cords imme- diately. 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. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. The following table shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage num- ber, the heavier the cord.
| | | | Minimum Gage for Cord Sets |

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 medication. 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 clothing, 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 fin- ger on the switch or plugging in tools that have the switch on invites accidents.
•Remove adjusting keys or switches before turning the tool on. A wrench or 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 balance 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 plat- form. Holding the work by hand or against your body is unstable and may lead to a loss of con- trol.
•Do not force tool. Use the correct tool for your application. The correct tool will do the job bet- ter and safer and 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 dangerous 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 con- dition 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 another tool.
SERVICE
•Tool service must be performed only by qualified repair personnel. Service or maintenance 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 Safety Rules for Hammer Drills
•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 safety goggles or other eye protection. Hammering and drilling operations cause chips to fly. Flying particles can cause permanent eye damage.
•Wear ear protectors when hammering for extended periods of time. Temporary hearing loss or serious ear drum damage may result from high sound levels generated by hammer drilling.
•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.
•Do not overreach while operating the tool. Maintain a balanced working stance at all times. When necessary, use only properly positioned, safe, platforms and scaffolding. WORK SAFE.
•Hammer bits and tools get hot during operation. Wear gloves when touching them.
CAUTION: Wear appropriate personal hearing protection during use. Under some con-
ditions and duration of use, noise from this product may contribute to hearing loss.
CAUTION: DO NOT TOUCH ANY METAL PARTS OF THE TOOL when drilling or driving into walls, floors or wherever live electrical wires may be encountered! Hold the tool only by insu- lated grasping surfaces to prevent electric shock if you drill or drive into a live wire.

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other con- struction activities contains chemicals known to cause cancer, birth defects or other reproduc- tive harm. Some examples of these chemicals are:
•lead from lead-based paints,
•crystalline silica from bricks and cement and other masonry products, and
•arsenic and chromium from chemically-treated lumber (CCA).
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscop- ic particles.
•Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and other construction activities. Wear protective clothing and wash exposed areas with soap and water. Allowing dust to get into your mouth, eyes, or lay on the skin may promote absorption of harmful chemicals.
WARNING: Use of this tool can generate and/or disburse dust, which may cause serious and permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory protection appropriate for the dust exposure. Direct particles away from face and body.
Side Handle
CAUTION: Always use side handle when provided and hold hammerdrill with both hands. A side handle is supplied with this hammerdrill. It clamps to the front of the gear case as shown in Figure 1 and can be rotated 360˚ to permit right or left hand use.
Switch (Fig. 2)
To start hammerdrill, depress the trigger switch (A). To stop hammerdrill, release the switch. To lock the trigger switch in the ON position for continuous operation, depress the trigger switch and push up the locking button (B). The tool will continue to run. To turn the tool OFF, from a locked ON condition, squeeze and release the trigger once. 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 hammerdrill is mounted in a drill press stand or other wise held stationary. Be sure to release the locking mechanism before disconnecting the plug from the power supply. Failure to do so will cause the hammerdrill to start immediately the next time it is plugged in. Damage or injury could result.
The variable speed trigger switch permits speed control. The farther the trigger switch is depressed, the higher the speed of the hammerdrill.
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.
The reversing lever (C) is used to reverse the hammerdrill for backing out screws or jammed bits. It is located above the trigger, shown. To reverse the hammerdrill, turn it OFF and push the reversing lever to the left (when viewed from the chuck end). To position the lever for forward operation, turn the hammerdrill OFF and push the lever to the right.
Hammer/Drill Selector
To switch the tool from the drilling mode to the hammering mode (or vice-versa) rotate the dial on the applicable symbol shown in Figure 3. For straight drilling, align the drill bit symbol toward the
