MOTOr
Be sure your power supply agrees with the voltage marked on the nameplate. 120 Volts AC 60Hz
means alternating current only. Voltage decrease of more than 10% will cause loss of power and
over heating. All Porter Cable tools are factory-tested. If this tool does not operate, check the power
supply line for blown fuses and the plug and receptacle for proper contact.
Accessories must be rated for at least the speed recommended on the tool warning label.
Accessories running over rated speed can fly apart and cause injury. Accessory ratings must always be
above tool speed as shown on tool nameplate.
To reduce the risk of injury, turn unit off and disconnect it from power source
before installing and removing accessories, before adjusting or when making repairs. An
accidental start-up can cause injury.
NEVER modify the power tool or any part of it. Damage or personal injury could result.
ATTAcHING ABrASIvE PAPEr
your sander is designed to use 1/4 sized sanding sheets. you can size this paper by
a. cutting full sized (9" x 11") sandpaper into 1/4 sheets of 4-1/2" x 5-1/2".
b. cutting 1/2 sheet sandpaper into two 4-1/2" x 5 1/2" sheets. Pre-cut 4-1/2" x 5-1/2" sandpaper
is available at extra cost.
For normal operations, to attach the abrasive paper to your unit:
1. Soften the stiff sandpaper by pulling it over the 90° edge of a table or other straight edge (Fig. 1).
Concentrate on softening the edges that will be clamped.
2. Release the front and rear clamps by pulling up on the clamp levers (A) Fig. 2, and disengaging
them from the tabs on the base plate.
3. Insert one long edge of the abrasive paper (C) Fig. 4 under the front paper clamp until it contacts
the paper-limiting ribs. Close the front paper clamp (B) Fig. 3 and hook it into the lock position
behind the tab on the base plate.
4. Stretch the paper over the sanding pad and insert it under the opposite clamp in the same way.
5. If you are using the dust extraction feature, perforate the sandpaper with the provided paper
punch (Fig. 5).
SwITcH
To turn the unit on, depress the "ON" side of the dust protected switch Fig. 6. To turn the tool off,
depress the "OFF" side of the switch.
PAPEr PUNcH
To reduce the risk of injury, turn unit off and disconnect it from power source
before installing and removing accessories, before adjusting or when making repairs. An
accidental start-up can cause injury.
A paper punch (Fig. 5) is provided with your sander to let you perforate regular sandpaper to make dust
collection possible.
To perforate your sandpaper, install the sandpaper on the tool as instructed in this manual. With the
sander turned off and unplugged, place the paper punch on the paper so that the tabs at the edges
of the punch are against any two adjacent sides (A) Fig. 5 of the sanding pad. Press the punch
against the pad so that the 8 points penetrate the paper. Press the punch into the pad as far as it will
go. Remove the paper punch. you can use an alternate method of perforating the paper by fastening
the punch to a suitable work surface with #8 flathead screws. Two holes are provided in the punch
for this purpose. Press the sander (with the paper attached) on the punch.
DUST cOLLEcTION
To reduce the risk of injury, turn unit off and disconnect it from power source
before installing and removing accessories, before adjusting or when making repairs. An
accidental start-up can cause injury.
To reduce the risk of serious personal injury, NEVER operate this tool with perforated
paper unless the dust collection system is in place.
Empty dust collection system frequently, especially when sanding resin-coated sur-
faces such as polyurethane, varnish, shellac, etc. Dispose of coated dust particles according to
the finish manufacturer's guidelines, or place in a metal can with a tight fitting metal lid. Remove
coated dust particles from the premises daily. The accumulation of fine sanding dust particles may
self ignite and cause fire.
Do not use a dust collection device when sanding metal. Doing so creates a fire hazard,
which may cause serious personal injury and/or damage to the tool.
To use the dust collection system, install the dust container assembly (A) Fig. 7 on the dust port as
far as it will go.
NOTE: To use your shop vacuum with the dust collection system, remove the dust container
(B) Fig. 7 by twisting it and pulling it away from the adapter. Remove the black tag (J) Fig. 7,
and attach your vacuum hose directly to the adapter port (C) (Fig. 8).
To empty the dust container, remove it and empty it into a trash receptacle.
USING THE SANDEr
To operate your sander, grasp it as shown in Fig. 9 and turn it on. Move it in long, sweeping strokes
along the surface, letting it do the work. Pushing down on the tool while sanding actually slows the
removal rate and produces an inferior quality surface. Be sure to check your work often. This sander
is capable of removing material rapidly, especially with coarse paper.
your sander is designed to sand flush on three sides for sanding in corners. Its small size and light
weight make it ideal for overhead work.
On the final sanding steps, a better finish will result if you sand only with the grain.
To produce the best finish possible, start with coarse grit sandpaper and change gradually to finer
and finer paper. A final sanding with a piece of well-worn fine sandpaper will produce a professional
looking finish that in many cases will need no hand sanding. The rate at which the dust container will
fill up will vary with the type of workpiece and the coarseness of the sandpaper.
For best results, empty the container frequently and check the opening for debris.
When sanding painted surfaces, you may find that the sandpaper loads up and clogs with paint.
A heat gun will work much better to remove paint before sanding. FOLLOw ALL SAFETY
INSTrUcTIONS IN THE HEAT GUN INSTrUcTION MANUAL.
