Extension Cords
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. 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.

Not Recommended
Sanding
Lead based 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 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.
Assembly/Adjustment Set-Up
WARNING: Always unplug sander from power supply before any of the following
operations.
Attaching Sandpaper
To operate the paper clamps on your sander, simply lift them up with your thumb, as shown
in Figure 1. Rotate the clamp lever downward until the clamp is fully opened.
Insert one short edge of the paper under the clamp. Push edge squarely up against the flat
wall of the platen and close the paper clamp on that side. Wrap the sandpaper around to fit
the other edge under the opposite paper clamp. Push as much paper under the second
clamp as possible before securing the paper clamp. Any slack in the paper will reduce
sanding performance.
NOTE: The QS540 comes with the paper punch shown in figure 2. The punch may be
permanently attached to a workbench by screwing it down using the two holes provided. If it
is on a work surface simply press the sander ( with sandpaper firmly attached ) down on the
punch to create the dust collection holes. If it is hand held simply press the punch against
the sander pad.
Operating Instructions
WARNING:
To reduce the risk of serious personal injury, read, understand and follow all
important safety warnings and instructions prior to using this tool.
Switch
To turn the tool ON, push the portion of the dust protected switch marked "I". To turn the tool
OFF, push the portion of the switch marked "O".
Operation
Grasp the sander and turn it ON. Move it in long, sweeping strokes along the surface, letting
it do the work. Utilize an even pressure across the sanding pad. Excessive pressure in the
corner area may cause damage. Pushing down on the tool while sanding actually slows the
removal rate and produces an inferior quality finish. Check your work often. Sander is
capable of removing material rapidly.
Dust Extraction
WARNING: Collected sanding dust from sanding surface coatings (polyurethane,
linseed oil, etc.) can self-ignite in sander dust bag or elsewhere and cause fire. To
reduce risk, empty bag frequently and strictly follow sander manual and coating
manufacturer's instructions.
Your sander comes equipped with a cloth canister to collect the dust generated while
sanding. To attach the canister onto the sander simply slide it firmly onto the dust extraction
port at the back of the sander and twist it slightly.
To empty the dust canister, remove it from the sander by simply twisting slightly and pulling it
straight back. Dump the sanding debris into an appropriate trash receptacle.
You may, if you prefer, attach a vacuum cleaner to the tool to collect the dust as you sand.
Simply remove the dust bag, and install a vacuum hose.
Ensure that the vacuum cleaner can be placed such that it will not tip over or interfere with
the motion of the sander. If this cannot be done, do not use the vacuum cleaner. Turn on the
vacuum cleaner before beginning to sand and turn it off after turning off the sander. Empty
vacuum cleaner as required.
Maintenance / Cleaning
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.
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.
