General Power Tool Safety Warnings |
|
Read all safety warnings and all instructions. Failure to follow the warnings |
! WARNING |
|
|
and instructions may result in electric shock, fire and/or serious injury. |
|
SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
Work area safety
Keep work area clean and well lit. Cluttered or dark areas invite accidents.
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 children and bystanders away while operating a power tool. Distractions can cause you to lose control.
Electrical safety
Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
Do not 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 for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
If operating a power tool in a damp location is unavoidable, use a Ground Fault Circuit Interrupter (GFCI) protected supply. Use of an GFCI reduces 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 a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and / or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dustrelated hazards.
Power tool use and care
Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.

Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained users.
Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use.
Many accidents are caused by poorly maintained power tools.
Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
Battery tool use and care
Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
When battery pack is not in use, keep it away from other metal objects like paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to another.
Shorting the battery terminals together may cause burns or a fire.
Under abusive conditions, liquid may be ejected from the battery, avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
Service
Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
Safety Rules for Cordless Hammer Drills
Wear ear protectors when impact drilling.
Exposure to noise can cause hearing loss.
Use auxiliary handle(s) if supplied with the tool. Loss of control can cause personal injury.
Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring. Cutting accessory contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.
Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body leaves it unstable and may lead to loss of control.
Do not drill, fasten or break into existing walls or other blind areas where electrical wiring may exist. If this situation is unavoidable, disconnect all fuses or circuit breakers feeding this worksite.
Always wear safety goggles or eye protection when using this tool. Use a dust mask or respirator for applications which generate dust.
Use thick cushioned gloves and limit the exposure time by taking frequent rest periods. Vibration caused by hammer-drill action may be harmful to your hands and arms.
Secure the material being drilled. Never hold it in your hand or across legs.
Unstable support can cause the drill bit to bind causing loss of control and injury.
Disconnect battery pack from tool before making any assembly, adjustments or changing accessories. Such preventive safety measures reduce the risk of starting the tool accidentally.
Position yourself to avoid being caught between the tool or side handle and walls or posts. Should the bit become bound or
-3-
BM 2610028048 12-12_BM 2610028048 12-12.qxp 12/5/12 10:27 AM Page 4
jammed in the work, the reaction torque of the tool could crush your hand or leg.
If the bit becomes bound in the workpiece, release the trigger immediately, reverse the direction of rotation and slowly squeeze the trigger to back out the bit. Be ready for a strong reaction torque. The drill body will tend to twist in the opposite direction as the drill bit is rotating.
Do not grasp the tool or place your hands too close to the spinning chuck or drill bit.
Your hand may be lacerated.
When installing a drill bit, insert the shank of the bit well within the jaws of the chuck.
If the bit is not inserted deep enough, the grip of the jaws over the bit is reduced and the loss of control is increased.
Do not use dull or damaged bits and accessories. Dull or damaged bits have a greater tendency to bind in the workpiece.
When removing the bit from the tool avoid contact with skin and use proper protective gloves when grasping the bit or accessory.
Accessories may be hot after prolonged use.
Check to see that keys and adjusting wrenches are removed from the drill before switching the tool "ON". Keys or wrenches can fly away at high velocity striking you or a bystander.
Do not run the tool while carrying it at your side. A spinning drill bit could become entangled with clothing and injury may result.
Additional Safety Warnings
GFCI and personal protection devices like electrician’s rubber gloves and footwear will further enhance your personal safety.
Do not use AC only rated tools with a DC power supply. While the tool may appear to work, the electrical components of the AC rated tool are likely to fail and create a hazard to the operator.
Keep handles dry, clean and free from oil and grease. Slippery hands cannot safely control the power tool.
Develop a periodic maintenance schedule for your tool. When cleaning a tool be careful not to disassemble any portion of the tool since internal wires may be misplaced or pinched or safety guard return springs may be improperly mounted.
Certain cleaning agents such as gasoline, carbon tetrachloride, ammonia, etc. may damage plastic parts.
Ensure the switch is in the off position before inserting battery pack. Inserting the battery pack into power tools that have the switch on invites accidents.
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities
contains chemicals known to cause cancer, birth defects or other reproductive 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 chemicallytreated lumber.
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 microscopic particles.

CHARGER INDICATORS, SyMBOLS AND MEANING (Model BC630)
If the indicator lights are “OFF”, the charger is not receiving power from power supply outlet.
If the green indicator light is
“ON”, the charger is plugged in but the battery pack is not
inserted, or the battery pack is fully charged.
If the green indicator light is “BLINKING”, the battery pack is being fast-charged. Fast-charging
will automatically stop when the battery pack is fully charged.
If the red indicator light is “ON”, the battery pack is too hot or cold for fast-charging. The charger will
automatically switch to fast-charging once a suitable temperature is reached.
If the red indicator light is
“BLINKING”, the battery pack 
cannot accept a charge or the contacts of the charger or battery pack are
contaminated. Clean the contacts of the charger or battery pack only as directed in these operating instructions or those supplied with your tool or battery pack.
CHARGING BATTERy PACK (Model BC630)
Plug charger cord into your standard power outlet.
With no battery pack inserted, the charger’s green indicator light will go ON. This indicates the charger is receiving power and the charger is ready for operation.
When you insert the battery pack into the charger. The charger’s green indicator light will begin to “BLINK”. This indicates that the battery is receiving a fast charge (Fig. 13).
When the indicator light stops “BLINKING” (and becomes a steady green light) fast charging is complete. The battery pack is fully charged and can be removed from the charger.
The battery pack may be used even though the light may still be blinking. The light may require more time to stop blinking depending on temperature.
The purpose of the green light is to indicate that the battery pack is fast-charging. It does not indicate the exact point of full charge. The light will stop blinking in less time if the battery pack was not completely discharged.
When you begin the charging process of the battery pack, a steady red light could also mean the battery pack is too hot or too cold.
Fast charging is only possible when the temperature range of the battery pack is between 32˚F (0˚C) and 113˚F (45˚C). When needed, the internal fan of the charger will turn on to aid the charging process and speed.
As soon as the battery pack reaches the correct temperature range, the battery charger will automatically switch to fast charging.
If the red indicator light is “BLINKING”, the battery pack cannot accept a charge.
•Check to make sure the battery pack is inserted into the charger properly.
•Clean the contacts of the charger or battery pack (e. g. by inserting and removing the battery several times) or replace the battery pack, as required.
When the battery pack is fully charged, unplug the charger (unless you're charging another battery pack) and slip the battery pack back into the tool.

TOOL TIPS
Following a few simple tips will reduce wear on the tool and the chance of injury to the operator.
NOTE: The high efficiency available from the rotary hammers can only be obtained if sharp and undamaged accessories are used. The “cost” to maintain sharp and undamaged accessories is more than offset by the “time saved” in operating the tool with sharp accessories.
You will extend the life of your bits and do neater work if you always put the bit in contact with the workpiece BEFORE pulling the trigger. During operation, hold the drill firmly and exert moderate, steady pressure. Too much pressure at low speed will stall the hammer. Too little pressure will keep the bit from cutting and cause excess friction by sliding over the surface. This can be damaging to the drill and bit.
Shanks of all drill bits should be wiped clean prior to using and immediately after removing.
Recall these instructions for safe operation:
1.Some materials require slow drilling speeds; whereas, others require higher speed to produce the best results.
2.All work must be supported or secured before drilling and steady, even pressure applied in line with the drill bit.
3.As the drill bit cuts through the opposite side, reduce the pressure and continue running the drill as the bit is withdrawn.
Materials such as glass, porcelain, ceramics, tiles, plastics, etc., should be drilled at low speeds with specially designed drill bits and lubricants.
DRILLING WOOD OR PLASTIC
If backing block is not used, ease up on the pressure just before the bit breaks through the wood to avoid splintering. Complete the hole from the opposite side immediately after the point breaks through. If bit binds, reverse the drilling operation to help remove the bit from the work.
DRILLING METAL
Make a center punch in the material for easier starting. Use enough pressure to keep the bit cutting. If the bit is allowed to merely spin in the hole, it will become dull within a short time. When drilling a larger hole, it is faster and easier on your power pack to first make a smaller hole and enlarge it to the required size. Lubricate the tip of the bit occasionally with CUTTING OIL for easier metal drilling. If bit binds, reverse the drilling to help remove the bit from the work.
DRILLING MASONRy
Use carbide-tipped masonry bit for cinder block, mortar, common brick, soft stone and other materials. The amount of pressure to be used is dependent upon the type of material being drilled. Soft materials require less pressure while the hard materials need more pressure to prevent the drill bit from spinning.
