GENERAL SAFETy RULES  
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.  
WARNING!  
Read all instructions. Failure to follow all instructions  
listed below may result in electric shock, fire and/or  
serious injury. The term “power tool” in all of the warn-  
ings listed below refers to your mains-operated (corded)  
power tool or battery-operated (cordless) power tool.  
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 these devices can  
reduce dust-related hazards.  
Do not wear loose clothing or jewelry. Contain long  
hair. Loose clothes, jewelry, or long hair can be drawn  
into air vents.  
SAVE THESE INSTRUCTIONS  
WORK AREA SAFETy  
Keep work area clean and well lit. Cluttered or dark  
areas invite accidents.  
Do not operate power tools in explosive atmo-  
spheres, 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  
Do not use on a ladder or unstable support. Stable

power tool. Distractions can cause you to lose control.  
ELECTRICAL SAFETy  
POWER TOOL USE AND CARE  
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 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 bind-  
ing 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 main-  
tained cutting tools with sharp cutting edges are less  
likely to bind and are easier to control.  
Do not expose power tools to rain or wet conditions.  
Water entering a power tool will increase the risk of elec-  
tric 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 exten-  
sion cord suitable for outdoor use. Use of a cord suit-  
able for outdoor use 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 safety equipment. Always wear eye protection.  
Safety equipment such as dust mask, non-skid safety  
shoes, hard hat, or hearing protection used for appropri-  
ate conditions will reduce personal injuries.  
Use the power tool, accessories and tool bits etc., in  
accordance with these instructions and in the manner  
intended for the particular type of power tool, taking  
into account the working conditions and the work to  
be performed. Use of the power tool for operations dif-  
ferent from those intended could result in a hazardous  
situation.  
Avoid accidental starting. Ensure the switch is in the  
off-position before plugging in. Carrying power tools  
with your finger on the switch or plugging in power tools  
that have the switch on invites accidents.

GENERAL SAFETy RULES  
SERVICE  
WARNING!  
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.  
To reduce the risk of injury, user must read instruction  
manual.  
Whenservicingapowertool,useonlyidenticalreplace-  
mentparts.FollowinstructionsintheMaintenancesec-  
tion of this manual. Use of unauthorized parts or failure to  
follow Maintenance instructions may create a risk of  
shock or injury.  
SPECIFIC SAFETy RULES  
Hold power 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.  
Know your power tool. Read operator’s manual care-  
fully. Learn its applications and limitations, as well  
as the specific potential hazards related to this tool.  
Following this rule will reduce the risk of electric shock,  
fire, or serious injury.  
Always wear safety glasses. Everyday eyeglasses  
have only impact-resistant lenses; they are NOT safety  
glasses. Following this rule will reduce the risk of serious  
personal injury.  
Protect your lungs. Wear a face or dust mask if the  
operation is dusty. Following this rule will reduce the  
risk of serious personal injury.  
properly and perform its intended function. Check for  
alignment of moving parts, binding of moving parts,  
breakage of parts, mounting, and any other conditions  
that may affect its operation. A guard or other part that  
is damaged should be properly repaired or replaced  
by an authorized service center. Following this rule will  
reduce the risk of shock, fire, or serious injury.  
Make sure your extension cord is in good condition.  
When using an extension cord, be sure to use one  
heavy enough to carry the current your product will  
draw. A wire gauge size (A.W.G.) of at least 14 is  
recommended for an extension cord 50 feet or less  
in length. A cord exceeding 100 feet is not recom-  
mended. If in doubt, use the next heavier gauge. The  
smaller the gauge number, the heavier the cord. An  
undersized cord will cause a drop in line voltage resulting  
in loss of power and overheating.  
Protect your hearing. Wear hearing protection during  
extended periods of operation. Following this rule will  
reduce the risk of serious personal injury.  
Inspect for and remove all nails from lumber before  
using this tool. Following this rule will reduce the risk of  
serious personal injury.  
Inspect tool cords periodically and, if damaged, have  
repaired at your nearest authorized service center.  
Constantly stay aware of cord location. Following this  
rule will reduce the risk of electric shock or fire.  
Check damaged parts. Before further use of the  
tool, a guard or other part that is damaged should  
be carefully checked to determine that it will operate  
If the power supply cord is damaged, it must be re-  
placed only by the manufacturer or by an authorized  
service center to avoid risk.  
Save these instructions. Refer to them frequently and  
use them to instruct others who may use this product. If  
you loan someone this product, loan them these instruc-  
tions also.

ELECTRICAL  
DOUBLE INSULATION  
EXTENSION CORDS  
Double insulation is a concept in safety in electric power  
tools, which eliminates the need for the usual three-  
wire grounded power cord. All exposed metal parts are  
isolated from the internal metal motor components with  
protecting insulation. Double insulated tools do not need  
to be grounded.  
When using a power tool at a considerable distance from  
a power source, be sure to use an extension cord that has  
the capacity to handle the current the tool will draw. An  
undersized cord will cause a drop in line voltage, resulting in  
overheating and loss of power. Use the chart to determine  
the minimum wire size required in an extension cord. Only  
round jacketed cords listed by Underwriter’s Laboratories  
(UL) should be used.  
WARNING:  
When working outdoors with a product, use an extension  
cord that is designed for outside use. This type of cord is  
designated with “WA” on the cord’s jacket.  
The double insulated system is intended to protect the  
user from shock resulting from a break in the product’s  
internal insulation. Observe all normal safety precautions  
to avoid electrical shock.  
Before using any extension cord, inspect it for loose or  
exposed wires and cut or worn insulation.  
NOTE:Servicingofaproductwithdoubleinsulationrequires  
extreme care and knowledge of the system and should be

side pressure to elongate a hole. Let the tool do the work.  
WARNING:  
Be prepared for binding at bit breakthrough. When these  
situations occur, the drill has a tendency to grab and kick  
in the opposite direction and could cause loss of control  
when breaking through material. If not prepared, this loss  
of control can result in possible serious injury.  
When drilling hard, smooth surfaces, use a center punch  
to mark the desired hole location. This will prevent the  
drill bit from slipping off-center as the hole is started.
