EXTENSION CORDS

When using an extension cord, be sure to use one heavy enough to carry the current your product will draw and is in good condition . An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. The following table 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.

			Minimum Gage for Cord Sets
Volts			Total Length of Cord in Feet
120V			0-25	26-50	51-100	101-150
240V			0-50	51-100	101-200	201-300

MOTOR

Your Black & Decker tool is powered by a Black & Decker-built motor. Be sure your power supply agrees with nameplate marking. 120 Volts AC only means your tool will operate on standard 60 Hz household power. Do not operate AC tools on DC. A rating of 120 volts AC/DC means that you tool will operate on standard 60 Hz AC or DC power. This information is printed on the nameplate. Lower voltage will cause loss of power and can result in over- heating. All Black & Decker tools are factory-tested; if this tool does not operate, check the power supply.

AUXILIARY HANDLE (FIG. 1)

An auxiliary handle (5) is furnished with your grinder and can be screwed into either side of the grinder housing. This handle SHOULD BE USED AT ALL TIMES to maintain complete control of the tool. TIGHTEN SECURELY.

STARTING AND STOPPING THE TOOL

To start the tool, slide the ON/OFF switch forward (1). For continuous operation, slide the switch (2) fully forward and press front end down. To stop the tool, release the ON/OFF switch. To stop the tool while running in continuous mode, press the rearward part of the switch.

NOTE: Do not switch the tool on or off while under load conditions. Allow the grinder to run up to full speed before touching the surface to be ground. Lift the tool from the surface before turning the tool off. CAUTION: Allow the tool to stop before setting down.

OVERLOAD

Overloading will cause damage to the motor of your angle grinder. This can happen if your angle grinder is subjected to heavy use for prolonged periods of time. Do not in any circumstances, attempt to exert too much pressure on your angle grinder to speed up your work. The abrasive accessories operate more efficiently when light pressure is exerted, thus avoiding a drop in the speed of your angle grinder.

GRINDING AND WIRE BRUSHING

ATTACHING THE WHEEL GUARD (FIG. 2)

Turn off and unplug the tool. NEVER GRIND OR BRUSH WITHOUT GUARD IN PLACE.

•Place the angle grinder on a table, spindle (9) facing up.

•Placing the spring washer (8) over the spindle and locate it on the shoulder (10).

•Place the guard onto the tool as shown.

•Place the flange (11) over the spindle with the protrusions facing towards the guard. Make sure that the screws are tight and that the guard can be rotated.

FITTING DEPRESSED CENTER WHEELS (FIGS. 3,4,5,6)

Turn off and unplug the tool. CAUTION: Never use any grinding wheels without the proper guard.

1.)Ensure that the guard is fitted properly. Place the inner flange (12) on the spindle (9) as shown (Fig. 3). Ensure that it is located on the two flats.

2.)Place the grinding wheel (4) on the spindle (9) and inner flange (12) as shown Fig. 4.

3.)Fit the threaded outer flange (14) making sure it is facing in the correct direction for the type of wheel fitted. For thick grinding wheels Fig. 5, the flange (14) is fitted with the raised portion facing towards the wheel. For thin grinding wheels, the flange (14) is fitted with the inner portion facing away from the wheel.

4.)Press in the spindle lock button and rotate the spindle until it locks. Keeping the lock button pressed in, tighten the outer flange with the spanner wrench provided as shown in Fig. 6. Hubbed wheels do not require mounting flanges and may be tightened with standard wrenches.

5.)When using a depressed-center wheel, hold the tool so that an angle of approximately 30° exists between the wheel and the work.

WARNING: Check rated speed on depressed-center wheel. Never use a wheel with rated speed lower than the speed on the nameplate of the tool.

Note: Sanding flap discs are considered to be grinding wheels and must be used with guards.

FITTING WIRE BRUSHES

Wire cup brushes screw directly on the spindle of the machine without the use of flanges. When using wire brushes, thread firmly on spindle by hand. The guard may be removed for brushing with flat wire brushes.

EDGE GRINDING

Edge grinding may be done with Type 27 depressed center wheels specifically designed for this purpose. These wheels are available locally. They must not be subject to side pressure. CAUTION: Wheels used for edge grinding may break if they bend or twist while being used for cut-off work or deep grinding. To reduce the risk of serious injury, limit the use of these wheels to shallow cutting and notching (less than 1/2” in depth). The open side of the guard must be positioned away from the operator.

SANDING

REMOVING THE WHEEL GUARD (FIG. 7 FOR SANDING AND USING FLAT WIRE BRUSHES.)

TURN OFF AND UNPLUG THE TOOL.

NOTE: To prevent loss of control, do not set tool down until accessory has completely stopped turning.

As shown in Fig. 7, place the grinder on a table, spindle up. Use a screwdriver to remove the

3 screws (6). Remove the flange (7), guard (4) and spring washer (8). Store these parts carefully.

PRECAUTIONS TO TAKE WHEN SANDING PAINT

1.Sanding of lead based paint is NOT RECOMMENDED due to the difficulty of controlling the contaminated dust. The greatest danger of lead poisoning is to children and pregnant women.

2.Since it is difficult to identify whether or not a paint contains lead without a chemical analy- sis, we recommend the following precautions when sanding any paint:

PERSONAL SAFETY

1.No children or pregnant women should enter the work area where the paint sanding is being done until all cleanup is completed.

2.A dustmask or respirator should be worn by all persons entering the work area. The filter should be replaced daily or whenever the wearer has difficulty breathing.

NOTE: ONLY THOSE DUSTMASKS SUITABLE FOR WORKING WITH LEAD PAINT DUST AND FUMES SHOULD BE USED. ORDINARY PAINTING MASKS DO NOT OFFER THIS PROTECTION. SEE YOUR LOCAL HARDWARE DEALER FOR THE NIOSH APPROVED PROPER MASK.

ENVIRONMENTAL SAFETY

1.Paint should be removed in such a manner as to minimize the amount of dust generated.

2.Areas where paint removal is occurring should be sealed with plastic sheeting of 4 mils thickness.

3.Sanding should be done in a manner to reduce tracking of paint dust outside the work area.

FITTING ABRASIVE DISCS

TURN OFF AND UNPLUG THE TOOL.

Use an abrasive disc with a backing pad for sanding with your angle grinder.

1.Remove the guard.

2.Place the flange, (backing pad and abrasive disc sold separately) and outer flange on the spindle as shown in Figure 8. Figure 8A shows how to attach an abrasive disc with a rub- ber backing pad.

3.Tighten the abrasive disc as shown in Figure 9 by depressing the spindle lock button and turning the abrasive disc by hand.

GENERAL INFORMATION

HELPFUL HINTS

•Hold your angle grinder with one hand on the body and the other hand firmly around the side handle as shown in Figure 10.

•Always position the guard so that as much of the exposed disc as possible is pointing away from you.

•Be prepared for a stream of sparks when the disc touches the metal. Direct away from people and flammable materials.

•Maintain an angle between the disc and work surface (Fig. 11) of approximately 30° when grinding and 10°-15° when sanding ( Fig. 12) for best tool control, material removal, and minimal loading.

WARNING: Always wear eye protection while operating this power tool including face and body protection when brushing.

TOOL MAINTENANCE

CLEANING: Blowing dust and grit out of the motor housing using compressed air is a necessary maintenance procedure. Dust and grit containing particles from metal grinding often accumulate on interior surfaces and could create an electrical shock hazard if not cleaned out. Never use solvents or harsh chemicals, use only mild soap and damp cloth to clean the tool. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid.

LUBRICATION

Black & Decker tools are properly lubricated at the factory and are ready for use. Tools should be lubricated regularly every year depending on usage. (Tools used on heavy duty jobs and tools exposed to heat may require more frequent lubrication.) This lubrication should be attempted only by trained power tool repairperson's such as those at Black & Decker service centers or in other qualified service personnel.

IMPORTANT

To assure product SAFETY and RELIABILITY, repairs, maintenance and adjustments should be performed by Black & Decker service centers or other qualified service personnel, always using Black & Decker replacement parts.
