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.

2610031969 09-13_2610031969 09-13.qxp 10/3/13 10:50 AM Page 3
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 Drill/Drivers
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 hold the tool with both hands. If the bit jams two hands will give you maximum control over torque reaction or kickback.
Always wear safety goggles or eye protection when using this tool. Use a dust mask or respirator for applications which generate dust.
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 or place the switch in the locked or off position before making any assembly, adjustments or changing accessories. Such preventive safety measures reduce the risk of starting the tool accidentally.
-3-
2610031969 09-13_2610031969 09-13.qxp 10/3/13 10:50 AM Page 4
Position yourself to avoid being caught between the tool or side handle and walls or posts. Should the bit become bound or 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 bit, insert the shank of the bit well within the chuck. If the bit is not inserted deep enough, the grip of the
chuck over the bit is reduced and the loss of control is increased. After bit insertion, pull on bit to ensure it is locked.
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 drill 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.

You will extend the life of your bits and do neater work if you always put the bit in contact with the work before pulling the trigger. During the oper ation, hold the tool firmly and exert light, steady pressure. Too
much pressure at low speed will stall the tool. Too little pressure will keep the bit from cutting and cause excess friction by sliding over the surface. This can be damaging to both tool and bit.

DRILLING WITH VARIABLE SPEED
The trigger controlled variable speed feature will eliminate the need for center punches in hard materials. The variable speed trigger allows you to slowly increase RPM. By using a slow starting speed, you are able to keep the bit from “wander ng”i. You can increase the speed as the bit “bites” into the work by squeezing the trigger.
DRIVING WITH VARIABLE SPEED
Variable speed drills will double as a power screwdriver by using a screwdriver bit in the drill mode. The technique is to start slowly, increasing the speed as the screw runs down. Set the screw snug yl by slowing to a stop. Prior to driving screws, pilot and clearance holes should be drilled.
FASTENING WITH SCREWS
This procedure shown in (Fig. 10) will enable you to fasten ma terials together with your Cordless Drill/Screwdriver without stripping, splitting or separating the material.
FASTENING
WITH SCREWS
1. Drill 2/3 diameter and 2/3 of screw length for soft materials, full length for hard materials.
Screw
Apply a slight even pressure when driving screws.
2. Drill same diameter as screw shank.
3. Countersink same diameter as screw head.
Adjustable
Screw
Drill
FIG. 10
First, clamp the pieces together and drill the first hole 2/3 the diam eter of the screw. If the material is soft, drill only 2/3 the proper length. If it is hard, drill the entire length.
Second, unclamp the pieces and drill the second hole the same diameter as the screw shank in the first or top piece of wood.
Third, if flat head screw is used, countersink the hole to make the screw flush with the surface. Then, simply apply even pressure when driving the screw. The screw shank clearance hole in the first piece allows the screw head to pull the pieces tightly together.
The adjustable screw drill accessory will do all of these oper ations quickly and easily.
Screw drills are available for screw sizes No. 6, 8, 10 and 12.
DRILL BITS
Always inspect drill bits for excessive wear. Use only bits that are sharp and in good condition.
TWIST BITS: Available with straight and reduced shanks for wood and light duty metal drilling. High speed bits cut faster and last longer on hard ma erialst.
CARBIDE TIPPED BITS: Used for drilling stone, con crete, plaster, cement and other unusually hard nonmetals. Use continuous heavy feed pres sure when employing carbide tip bits.
DRILLING WOOD
Be certain workpiece is clamped or anchored firm yl. Always apply pressure in a straight line with the drill bit. Maintain enough pressure to keep the drill “biting”.
When drilling holes in wood, twist bits can be used. Twist bits may overheat unless pulled out frequently to clear chips from flutes.
Use a “back-up” block of wood for work that is likely to splinter, such as thin materials.
You will drill a cleaner hole if you ease up on the pressure just before the bit breaks through the wood. Then complete the hole from the back side.
DRILLING METAL
There are two rules for drilling hard materials. First, the harder the material, the greater the pres sure you need to apply to the tool. Second, the harder the material, the slower the speed. Here are a couple of tips for drilling in metal. Lubri cate the tip of the bit occasionally with cutting oil except when drilling soft metals such as alu minum, cop per or cast iron. If the hole to be drilled is fairly large, drill a smaller hole first, then enlarge to the required size, it’s often faster in the long run. Main tain enough pressure to assure that the bit does not just spin in the hole. This will dull the bit and greatly shorten its life.
RUNNING NUTS AND BOLTS
Variable speed control must be used with caution for driving nuts and bolts with socket set attach ments. The technique is to start slowly, increasing speed as the nut or bolt runs down. Set the nut or bolt snugly by slowing the drill to a stop. If this procedure is not followed, the tool will have a tendency to torque or twist in your hands when the nut or bolt seats.
