4.Remove adjusting keys or switches 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.

5.Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the tool in unexpected situations.

6.Use safety equipment. Always wear eye pro- tection. Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appro- priate conditions.

7.Wear hearing protectors, ear plugs or muffs when using tool. Noise level may affect hearing with prolonged use.

Tool Use and Care

1.Use clamp 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.

2.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.

3.Do not use tool if switch does not turn it ON or OFF. Any tool that cannot be controlled with the switch is dangerous and must be repaired.

4.Disconnect the plug from the power source before making any adjustments, changing accessories, or storing the tool. Such preven- tive safety measures reduce the risk of starting the tool accidentally.

5.Store idle tools out of the reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.

6.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.

7.Check for misalignment or binding of moving parts, breakage of parts, and any other condi- tion that may affect the tool's operation.If dam- aged, have the tool serviced before using. Many accidents are caused by poorly maintained tools.

8.Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool may become haz- ardous when used on another tool.

9.Keep handles dry and clean; free from oil and grease. Allows for better control of the tool.

Service

1.Tool service must be performed only by quali- fied repair personnel. Service or maintenance performed by unqualified repair personnel could result in injury.

2.When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance Section of this manual. Use of unauthorized parts or failure to follow mainte- nance instructions may create a risk of electrical shock or injury.
