Work Area Tool USE and Care, Electrical Safety

GENERAL SAFETY RULES — FOR ALL BATTERY OPERATED TOOLS

WARNING!

READ AND UNDERSTAND ALL INSTRUCTIONS.

Failure to follow all instructions listed below, may result in electric shock, fire and/or serious personal injury.

SAVE THESE INSTRUCTIONS

WORK AREA

TOOL USE AND CARE

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 presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.

3.Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you to lose control. Protect oth- ers in the work area from debris such as chips and sparks. Provide barriers or shields as needed.

ELECTRICAL SAFETY

4.Do not abuse the cord. Never use the cord to carry the tool. Keep cord away from heat, oil, sharp edges, or moving parts. Replace damaged cords immediately. Damaged cords may create a fire.

5.A battery operated tool with integral batteries or a separate bat- tery pack must be recharged only with the specified charger for the battery. A charger that may be suitable for one type of battery may create a risk of fire when used with another battery.

6.Use battery operated tool only with specifically designated bat- tery pack. Use of any other batteries may create a risk of fire.

PERSONAL SAFETY

7.Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use tool while tired or un- der the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious per- sonal injury.

8.Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from mov- ing parts. Loose clothes, jewelry, or long hair can be caught in mov- ing parts.

9.Avoid accidental starting. Be sure switch is in the locked or off position before inserting battery pack. Carrying tools with your finger on the switch or inserting the battery pack into a tool with the switch on invites accidents.

10.Remove adjusting keys or wrenches before turning the tool on. A wrench or a key that is left attached to a rotating part of the tool may result in personal injury.

11.Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enable better control of the tool in unex- pected situations.

12.Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions.

13.Use clamps or other practical way 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.

14.Do not force 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.

15.Do not use tool if switch does not turn it on or off. A tool that cannot be controlled with the switch is dangerous and must be re- paired.

16.Disconnect battery pack from tool or place the switch in the locked or off position before making any adjustments, changing accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally.

17.Store idle tools out of reach of children and other untrained per- sons. Tools are dangerous in the hands of untrained users.

18.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 sparks, burns, or a fire.

19.Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools with sharp cutting edge are less likely to bind and are easier to control.

20.Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool’s opera- tion. If damaged, have the tool serviced before using. Many acci- dents are caused by poorly maintained tools. Do not use a damaged tool. Tag damaged tools “Do not use” until repaired.

21.Use only accessories that are recommended by the manufac- turer for your model. Accessories that may be suitable for one tool may create a risk of injury when used on another tool.

SERVICE

22.Tool service must be performed only by qualified repair person- nel. Service or maintenance performed by unqualified personnel may result in a risk of injury.

23.When servicing a tool, use only identical replacement parts. Fol- low instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance Instructions may create a risk of shock or injury.
