	GENERAL SAFETY RULES		tors. There is an increased risk of electric shock if
		USA002-2	your body is grounded.
	(For All Tools)		6. Do not expose power tools to rain or wet condi-
			tions. Water entering a power tool will increase the

risk of electric shock.

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

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.

Electrical Safety

4.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 insula-

tion eliminates the need for the three wire grounded power cord and grounded power supply system.

5.Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigera-

7.Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock.

8.When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W”.

These cords are rated for outdoor use and reduce 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 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 switch is off before plugging in. Carrying tools with your finger on the switch or plugging in tools that have the switch on invites accidents.

12.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.

13.Do not overreach. Keep proper footing and balance at all times. Proper footing and balance

enables better control of the tool in unexpected situations.

14.Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions. Ordinary eye or sun glasses are NOT eye protection.

Tool Use and Care

15.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.

16.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.

17.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.

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

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

20.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.

21.Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tools operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools.

22.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

23.Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury.

24.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 Maintenance instructions may create a risk of electric shock or injury.

USE PROPER EXTENSION CORD: 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. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Table 1 shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.

SPECIFIC SAFETY RULES

USB040-5

DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to sander safety rules. If you use this tool unsafely or incorrectly, you can suffer serious personal injury.

1.Hold 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.

2.Always use safety glasses or goggles. Ordinary eye or sun glasses are NOT safety glasses.

3.Hold the tool firmly.

4.Do not leave the tool running. Operate the tool only when hand-held.

5.This tool has not been waterproofed, so do not use water on the workpiece surface.

6.Ventilate your work area adequately when you perform sanding operations.

3

7.Use of this tool to sand some products, paints To start the tool, simply pull the switch trigger. Release

and wood could expose user to dust containing hazardous substances. Use appropriate respiratory protection.

8.Be sure that there are no cracks or breakage on the pad before use. Cracks or breakage may cause a personal injury.
