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 injury.
SAVE THESE INSTRUCTIONS
WORK AREA
1. Keep your work area clean and well lit. Cluttered benches and dark areas invite
accidents.
2. Do not operate power tools in explosive atmospheres, such as in the pres-
ence of flammable liquids, gases, or dust. Power tools create sparks which may
ignite the dust or fumes.
SKU 90120 For technical questions, please call 1-800-444-3353. PAGE 2
3. Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to lose control. Protect others in the work area from
debris such as chips and sparks. Provide barriers or shields as needed.
ELECTRICAL SAFETY
4. 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 electrician if you are in doubt as to whether the outlet is properly grounded. If the tools should electrically malfunction or break down, ground-
ing provides a low resistance path to carry electricity away from the user.
5. 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 polarized outlet. Do not change the plug in
any way. Double insulation
power cord and grounded power supply system.
6. 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.
eliminates the need for the three wire grounded
7. Do not expose power tools to rain or wet conditions. Water entering a power
tool will increase the risk of electric shock.
8. Do not abuse the Adapter’s power cord. Never use the Power Cord to carry
the Charger or pull the Plug from an outlet. Keep the Power Cord away from
heat, oil, sharp edges, or moving parts. Replace damaged Power Cords immediately. Damaged Power Cords increase the risk of electric shock.
PERSONAL SAFETY
9. Stay alert. Watch what you are doing, and use common sense when operating a power tool. Do not use a power 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.
10. 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.
11. Avoid accidental starting. Be sure the Rotation Button (33) is in the locked
position before inserting the Battery. Carrying power tools with your finger on
the trigger, or inserting the Battery with the trigger depressed, invites accidents.
12. Do not overreach. Keep proper footing and balance at all times. Proper footing
and balance enables better control of the power tool in unexpected situations.

13. Use safety equipment. Always wear eye protection. Dust mask, nonskid safety
shoes, hard hat, or hearing protection must be used for appropriate conditions.
Always wear ANSI approved safety goggles when working with this tool.
TOOL USE AND CARE
14. Use clamps (not included) or other practical ways to secure and support the
workpiece to a stable platform. Holding the work by hand or against your body is
unstable and may lead to loss of control.
15. 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 is designed.
16. Do not use the power tool if the trigger does not operate it. Any tool that cannot
be controlled with the trigger is dangerous and must be replaced.
17. Remove the battery from the tool and set the Rotation Button (33) to its cen-
ter, locked position before making any adjustments, changing accessories,
or storing the tool. Such preventive safety measures reduce the risk of starting
the tool accidentally.
18. Store idle tools out of reach of children and other untrained persons. Tools
are dangerous in the hands of untrained users.
19. Maintain tools with care. Keep drill bits sharp and clean. Properly maintained
accessories with a sharp cutting edge are less likely to bind and are easier to control. Do not use a damaged tool or accessory. Tag damaged tools “Do not use” until
repaired.
20. Check for misalignment or binding of moving parts, breakage of parts, and
any other condition that may affect the tool’s operation. If damaged, have the
tool serviced before using. Many accidents are caused by poorly maintained
tools.
21. 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
22. Tool service must be performed only by qualified repair personnel. Service or
maintenance performed by unqualified personnel could result in a risk of injury.
23. When servicing a tool, use only identical replacement parts. Follow instruc-
tions in the
Use of unauthorized parts or failure to follow maintenance instructions may create
a risk of electric shock or injury.

section of this manual.
