Belt life will be greatly increased by keeping the tracking adjustment set properly. To prevent
the sanding belt from rubbing against the sander housing, keep the edge of the belt about
7/64 in. (2.7mm) to 13/64 in. (5.1mm) from the housing as shown in 

figure 4

.

Handy Hints

• Always start your belt sander before it is in contact with the workpiece and do not switch it

off until after it has been lifted from the workpiece.

• Always hold your belt sander with two hands.
• Where possible, clamp the workpiece to a work bench or similar sturdy surface.
• Use the correct grit sanding belt for your application. The following is a suggested list of

belt grits to use with different materials.

Tool Care And Maintenance

Never apply excessive force when you use your belt sander. Too much force can result in an
overload and cause damage to the motor or the workpiece. If your belt sander becomes too
hot, operate it without load for 2 minutes. Always keep the air cooling vents clear. To clean
your belt sander, proceed as follows: 

WARNING: To prevent accidental operation, turn off and unplug sander before

performing the following operations.

Failure to do this could result in serious 

personal injury. 

• Use a clean dry paint brush to clear vents and ducts.
• Clean the housings using a clean damp cloth (do not use solvents, gas or turpentine.)

IMPORTANT: 

To assure product SAFETY and RELIABILITY, repairs, maintenance and

adjustment should be performed by authorized service centers or other qualified service
personnel, always using identical replacement parts.

• Clean your tool out periodically.

Other Important Safety Warnings and Instructions

Sanding 
Lead Base Paint

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

Personal Safety

• No children or pregnant women should enter the work area where the paint sanding is

being done until all clean up is completed.

• A dust mask 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 dust masks 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 proper (NIOSH approved) mask.

• NO EATING, DRINKING or SMOKING should be done in the work area to prevent

ingesting contaminated paint particles. Workers should wash and clean up BEFORE
eating, drinking or smoking. Articles of food, drink, or smoking should not be left in the work
area where dust would settle on them.

Environmental Safety

• Paint should be removed in such a manner as to minimize the amount of dust generated.
• Areas where paint removal is occurring should be sealed with plastic sheeting of 4 mils

thickness.

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

Cleaning And Disposal

• All surfaces in the work area should be vacuumed and thoroughly cleaned daily for the

duration of the sanding project. Vacuum filter bags should be changed frequently.

• Plastic drop cloths should be gathered up and disposed of along with any dust chips or

other removal debris. They should be placed in sealed refuse receptacles and disposed of
through regular trash pick-up procedures. During clean up, children and pregnant women
should be kept away from the immediate work area.

• All toys, washable furniture and utensils used by children should be washed thoroughly

before being used again.

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 your 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.

Use of Extension Cords

Make sure the extension cord is in good condition before using. Always use the proper size
extension cords with the tool – that is, proper wire size for various lengths of cord and heavy
enough to carry the current the tool will draw. Use of an undersized cord will cause a drop in
line voltage resulting in loss of power and overheating. For proper size cords see chart
below.

SAVE THESE INSTRUCTIONS

Adjustments

WARNING: To prevent accidental operation, turn off and unplug sander before

performing the following operations.

Failure to do this could result in serious 

personal injury. 

3 Position Handle - Figure 1 & 1A

A locking mechanism on the side of the handle can be loosened to allow the handle to move.
To adjust the handle, pull out on the locking arm (

Figure 1

) and move the handle to the

desired position (

Figure 1A

). Once the handle is in position, push the locking arm in to lock

the handle into position.

2 Position Belt Cover - Figure 2 & 3

The belt sander has an aluminum sanding belt cover at the front. When the handle is
positioned in the uppermost position, this cover can be raised as shown in 

Figure 2 

(Arrow 1

) and locked in this position to:

a.) Improve accessibility to narrow areas.
b.) Allow the use of the smaller diameter front roller to sand with (normally the aluminum
cover prevents this when in the “down” position). 
c.) Expose the top part of the belt for more versatile sanding (

Figure 3

). 

To lower the belt cover, grasp the flange on the side and move it slightly in the
direction shown in Figure 2 (Arrow 2) and return it to its closed position.
Note: 

The sanding belt cover cannot be locked in its raised position unless the bail handle is

in the uppermost position. 

WARNING: The sanding belt is exposed when the belt cover is raised. Use extra

caution when operating in this mode.

Adjusting The Sanding Belt Tracking - Figure 4

Turn the machine upside down (

Figure 4

), hold it firmly with one hand, start motor and

release switch immediately after observing tracking of sanding belt. If abrasive belt runs
outward, turn tracking adjustment knob clockwise and counterclockwise if belt runs inward.
