Gereeral Safety Instructions

WORK AREA

* Keep your work area clean and well lit. Cluttered benches

and dark areas invite accidents.

* 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 operat-

ing a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

* 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, ff the tools should electrically malfunction or break down, grounding provides a low resist-

ance path to carry electricity away from the user. Applicable only to Class I (grounded) tools.

* 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. ff 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 the three wire grounded power cord and grounded

power supply system. Applicable only to Class II (double

insulated) tools.

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. Don't expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. 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.

When operating a power tool outside, use an outdoor exten-

sion cord marked "W-A" or "W." These cords are rated for outdoor use and reduce the risk of electric shock.

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.

* Dressproperly.Donotwearlooseclothingorjewelry.

Containlonghair.Keep your hair, clothing, and gloves

away from moving parts. Loose clothes, jewelry, or long hair

can be caught in moving parts. Air vents often cover moving

parts and should also be avoided.

* 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.

* 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.

* Do not overreach. Keep proper footing and balance at all

times. Proper footing and balance enables better control of 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.

TOOL USE AND CARE

* 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.

* 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.

* 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.

* Disconnect the plug from the power source before making

any adjustments, changing accessories, or storing the

tool Such preventative safety measures reduce the risk of starting the tool accidentally.

* Store idle tools out of reach of children and other untrained

persons. Tools are dangerous in the hands of untrained users.

* 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 misalignment or binding of moving parts, break-

age 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.

* Use only accessories that are recommended by the manu-

facturer for your model Accessories that may be suitable for one tool, may become hazardous when used on another tool.

SERVICE

* Tool service must be performed only by qualified repair

personnel Service or maintenance performed by unquafified personnel could result in a risk of injury.

, 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.

Additional Specific Safety Instructions

for Grinders

. Always use proper guard with grinding wheel. A guard pro-

tects operator from broken wheel fragments and wheel contact.

* Accessories must be rated for at least the speed recom-

mended on the tool warning label Wheels and other acces- sories running over rated speed can fly apart and cause injury.

Accessory ratings must be above fisted minimum wheel speed

as shown on tool nameplate.

* 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.

, Do not use Type 11 (flaring cup) wheels on this tool Using

inappropriate accessories can result in injury.

* Before using, inspect recommended accessory for cracks

or flaws, ff such a crack or flaw is evident, discard the

accessory. The accessory should also be inspected when-

ever you think the tool may have been dropped. Flaws may cause wheel breakage.

, When starting the tool with a new or replacement wheel, or

a new or replacement wire brush installed, hold the tool in a well protected area and let it run for one minute, ff the

wheel has an undetected crack or flaw, it should burst in less than one minute, ff the wire brush has loose wires, they will be detected. Never start the tool with a person in line with the

wheel This includes the operator.

, Avoid bouncing the wheel or giving it rough treatment. If

this occurs, stop the tool and inspect the wheel for cracks or flaws.

* Direct sparks away from operator, bystanders or flamma-

ble materials. Sparks may be produced while using a sander or grinder. Sparks may cause burns or start fires.

, Always use side handle. Tighten the handle securely. The

side handle should always be used to maintain control of the tool at all times.

* Do not operate this tool for long periods of time. Vibration

caused by the operating action of this tool may cause permanent injury to fingers, hands, and arms. Use gloves to provide extra cushion, take frequent rest periods, and limit daily time of use.

, Clean out your tool often, especially after heavy use. Dust

and grit containing metal particles often accumulate on interior surfaces and could create an electric shock hazard.

SURFACE GRINDING WITH GRINDING WHEELS

1. Allow the tool to reach full speed before touching the tool to the work surface.

2. Apply minimum pressure to the work surface, allowing the tool to operate at high speed. Grinding rate is greatest when the tool operates at high speed.

3. Maintain a 20 ° to 30° angle between the tool and work surface.

4. Continuously move the tool in a forward

and back motion to avoid creating gouges

20°_30°

in the work surface.

5. Remove the tool from work surface before turning tool off. Allow the tool to stop rotating before laying it down.

EDGE GRINDING WITH GRINDING WHEELS

CA UTION: Wheels used for cutting and edge grinding may break ff they bend or twist while the tool is being used to do cut-off work or deep grinding. To reduce the risk of serious injui%, limit the use of these wheels with a standard Type 27 guard to shallow cutting and notching (less than 1/2" in depth). The open side of the guard must be positioned away from the operator. For deeper cutting with a

Type 1 cut-off wheel use a closed, Type 1guard. See the chart on pages 4-5 for more information. Type 1guards are available at extra cost from your local dealer or authorized service center.

1. Allow the tool to reach full speed before

touching the tool to the work surface.

2. Apply minimum pressure to the work

surface, allowing the tool to operate at high speed. Grinding rate is greatest when the tool operates at high speed.

3. Position yourself so that the open-

underside of the wheel is facing away

from you.

4. Once a cut is begun and a notch is

established in the workpiece, do not change the angle of the cut. Changing

the angle will cause the wheel to bend

and may cause wheel breakage. Edge

grindingwheelsarenotdesignedtowithstandsidepressures causedbybending.

5. Removethetoolfromtheworksurfacebeforeturningthetool off.Allowthetooltostoprotatingbeforelayingitdown.

WARNING: Do not use edge grinding/cutting wheels for surface

grinding applications because these wheels are not designed for

side pressures encountered with surface grinding. Wheel breakage and injury may result.

SURFACE FiNiSHING WITH SANDING FLAP DISCS

1. Allow the tool to reach full speed before touching the tool to the work surface.

2. Apply minimum pressure to work surface, allowing the tool to operate at high speed. Sanding rate is greatest when the tool

operates at high speed.

3. Maintain a 5 ° to 10° angle between the tool and work surface. _

4. Continuously move the tool in a 5o_10° forward and back motion to avoid

creating gouges in the work surface.

5. Remove the tool from work surface before turning tool off. Allow the tool to stop rotating before laying it down.

ing disc and clamp nut are snug.

To remove the wheel, grasp and turn the backing pad and sanding pad while depressing the spindle lock button.

USING SANDING BACKING PADS Choose the proper grit sandpaper for your application. Sandpaper

is available in various grits. Coarse grits yield faster material removal rates and a rougher finish. Finer grits yield slower materi-

al removal and a smoother finish. Begin with coarse grit discs for fast, rough material removal.

Move to a medium grit paper and finish with a fine grit disc for optimal finish.

Coarse 16 - 30 grit Medium 36 - 80 grit

Fine Finishing 100 - 120 grit

Very Fine Finishing 150 - 180 grit

1. Allow the tool to reach full speed before touching tool to the work surface.

2. Apply minimum pressure to work surface, allowing the tool to operate at high speed. Sanding rate is greatest when the tool operates at high speed.

3. Maintaina5°to15°anglebetweenthe toolandworksurface.Thesanding

discshouldcontactapproximately oneinchofworksurface. 5o_15°

4. Move the tool constantly in a straight

line to prevent burning and swirling of work surface. Allowing the tool to rest on the work surface without moving, or moving the tool in a circular motion causes burning and swirling marks on

the work surface.

5. Remove the tool from work surface before turning tool off. Allow the tool to stop rotating before laying it down.

Mounting and Using Wire Brushes and Wire Wheels

Wire cup brushes or wire wheels screw directly on the grinder spin-

dle without the use of flanges. Use only wire brushes or wheels pro-

vided with a 5/8"-11 threaded hub. A Type 27 guard is required when using wire brushes and wheels. .&CAUTION: Wear work gloves when handling wire brushes

and wheels. They can become sharp.

CAUTION: Wheel or brush must not touch guard when mounted or while in use. Undetectable damage could occur to the accesso_ causing wires to fragment from accessory wheel or cup.
