WORK AREA
Keep your work area clean and well lit. Cluttered benches and dark areas invite ac-
cidents.
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. Distrac-
tions 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 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 a three-wire
grounded power cord and grounded power-supply system.
Avoid 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 grounded.
Don’t expose power tools to rain or wet conditions. A wet power tool will increase the
risk of electric shock.
Do not abuse the cord. Never use the cord to carry the tool. Never tug on the cord
to pull the plug from an outlet. Keep the cord away from heat, oil, sharp edges, and
moving parts. Replace damaged cords immediately. Damaged cords increase the risk
of electric shock.
When operating a power tool outdoors, use an extension cord suitable for outdoor
use. These cords are rated for outdoor use and reduce the risk of electric shock.
If an extension cord is necessary, a cord with adequate size conductors should
be used to prevent excessive voltage drop, loss of power, or overheating. The table
shows the correct size to use, depending on cord length and nameplate amperage rating
of tool. If in doubt, use the next heavier gauge. Always use UL and CSA listed extension
cords.

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 clothes, jewelry, or long
hair can be caught in moving parts.
Do not overreach. Keep proper footing and balance at all times. Proper footing and
balance enables you to better control 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.
If devices are provided to connect to dust extraction and collection equipment,
ensure they are properly connected. Using these devices can reduce dust-related
hazards.
TOOL USE AND CARE
Use clamps or other practical ways to secure and support the work piece to a
stable platform. Holding the work piece by hand or against your body is unstable and
may lead to loss of control.
Do not force the tool. Use the correct tool for your application. The correct tool will
do the job better and safer at the rate for which it’s designed.
Do not use the tool if the switch does not turn it on or off. Any tool that cannot be
controlled with the switch is dangerous and must be repaired.
Store idle tools out of the reach of children and other untrained persons. Tools are
dangerous in the hands of untrained users.
Disconnect the plug from power source before making any adjustments, changing
accessories, or storing power tools. Such preventive safety measures reduce the risk
of starting the power tool accidentally.
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 misaligned or bound moving parts, broken parts, and any other condi-
tion that may affect the tool’s operation. If it’s damaged, have the tool serviced
before using it again. 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 type of tool may be dangerous when used for
another tool.
Use tools in good condition, adapted to the task to be performed. This do-it-yourself
equipment should be used as such and not be considered as heavy-duty equipment.

SERVICE
Tool service must only be performed by qualified repair persons. Service or maintenance
performed by unqualified persons could result in a risk of injury. For questions on war-
ranty or service, call our toll-free number at 1-866-513-6723.
SPECiFiC SaFEtY RuLES
Hold the tool by insulated gripping surfaces when performing an operation where
the cutting tools may contact hidden wiring. Contact with a “live” wire will make
exposed metal parts of the tool “live,” and can shock the operator, resulting in serious
personal injury.
Do not touch the bit immediately after drilling. The hot bit can cause a severe burn.
Do not overload the motor.
When changing accessories, use the appropriate collets.
When using the drill for an extended period of time, take regular breaks to allow the
drill to cool down.
Do not work with a faulty grinding or cutting disc or bent mandrel.
Remove the plug from the outlet before carrying out any adjustment, servicing, or
maintenance.
Ensure that the disc dimensions are compatible with the mandrel.
Abrasive discs and grinding stones should be stored with care in accordance with
manufacturer’s instructions.
Inspect the discs and grinding stones before using. Do not use chipped, cracked, or
otherwise defective products.
Ensure that mounted discs and grinding stones are fitted in accordance with the
manufacturer’s instructions.
Ensure that the abrasive product is correctly mounted and tightened before using.
Run the tool in no-load for 30 seconds in a safe position. Stop immediately if there is
considerable vibration or if other defects are detected. If this happens, disconnect the tool
from the main power supply, and check the machine to determine the cause.
Do not use separate reducing bushings or adapters to adapt large hole abrasive discs
and grinding stones.
Check that the work piece is properly supported.
Do not use the cutting disc for side grinding.
Ensure that sparks resulting from using the drill do not create a hazard (e.g., come
in contact with operator or bystanders, or ignite flammable substances).
Ensure that ventilation openings are kept clear while working in dusty conditions.
If you need to clear the dust, disconnect the tool from the main supply (use non-metallic
objects) and avoid damaging internal parts.
