Vibration Safety
This tool vibrates during use.
Repeated or long-term exposure to vibration may
cause temporary or permanent physical injury,
particularly to the hands, arms and shoulders.

1. Tools marked with “Grounding Required” have
a three wire cord and three prong grounding

Double Insulated Tools: Tools
with Two Prong Plugs
B=(+'(;$V8/$LQ)/8-W$)+=W
1. Tools marked “Double Insulated” do not
require grounding. They have a special
double insulation system which satisfies
OSHA requirements and complies with
the applicable standards of Underwriters
Laboratories, Inc., the Canadian Standard
Association, and the National Electrical Code.
2. Double insulated tools may be used in either of the
120 volt outlets shown in the preceding illustration.$$$

Extension Cords
1. Grounded tools require a three wire extension cord.
Double Insulated tools can use either
a two or three wire extension cord.
2. As the distance from the supply outlet increases,
you must use a heavier gauge extension cord.
Using extension cords with inadequately sized wire
causes a serious drop in voltage, resulting in loss of
power and possible tool damage. ]%''$7*\+'$1F^
3. The smaller the gauge number of the wire, the
greater the capacity of the cord. For example,
a 14 gauge cord can carry a higher current
than a 16 gauge cord. ]%''$7*\+'$1F^
4. When using more than one extension cord to make
up the total length, make sure each cord contains at
least the minimum wire size required. ]%''$7*\+'$1F^
5. If you are using one extension cord for more
than one tool, add the nameplate$amperes
and use the sum to determine the required
minimum cord size. ]%''$7*\+'$1F^
6. If you are using an extension cord outdoors, make
sure it is marked with the suffix “W-A” (“W” in
Canada) to indicate it is acceptable for outdoor use.
7. Make sure the extension cord is properly wired
and in good electrical condition. Always replace
a damaged extension cord or have it repaired
by a qualified electrician before using it.
8. Protect the extension cords from sharp objects,
excessive heat, and damp or wet areas.

Workpiece and Work Area Set Up
1. Workpiece selection:
a. Workpiece must be free of foreign objects.
b. Wear a NIOSH-approved respirator and
have appropriate ventilation whenever
sanding pressure treated lumber.
2. Designate a work area that is clean and well lit.
The work area must not allow access by children
or pets to prevent distraction and injury.
3. Route the power cord along a safe route to reach
the work area without creating a tripping hazard or
exposing the power cord to possible damage. The
power cord must reach the work area with enough
extra length to allow free movement while working.
4. Secure loose workpieces using a vise or clamps
(not included) to prevent movement while working.
5. There must not be objects, such as utility lines,
nearby that will present a hazard while working.

1. Press the Clamp Wire Tab inward on both
sides of the unit and swing the clamps
on both sides up, out, and down.
2. Cut standard size 9″ x 11″ sheets of sandpaper
into thirds lengthwise to fit the Backing Pad. There
will be a little extra to overlap and fit under the
Clamp Wire. Z8$-8($=;'$(8/-$8/$V/*?'.$;*-.9*9'/F
3. After wrapping the overlapped edges of sandpaper
under the Clamp Wire, push the Clamp Wire back
into its locked position, thus trapping the ends of
the sandpaper in front and rear of the sander. The
sandpaper should now be held securely in place.
4. Use the included Hole Punch to
punch holes in the sandpaper.
Setting and Testing
1. Ensure the sanding paper is correctly attached to the
Sander and the Hole Punch has been used to make
holes in the sanding paper. Check that the holes
align with the holes in the Backing Pad so the Dust
Box will collect debris during the sanding operation.
2. Switch the On/Off Switch to ON and run
the tool for at least 30 seconds.
3. If abnormal noise/vibration occurs or the
sandpaper slips off, have the problem
corrected before further use.
General Instructions for Use
1. Hold the Sander using the Handle.
2. Make sure that the Switch is in the
off-position, then plug in the tool.
3. Hold the Sander securely with both hands.
Turn the Sander on by pressing the Switch ON.
0123435j The tool will restart automatically if stalled.
4. Always run the Sander for a few seconds
before contacting the workpiece.
5. Contact the workpiece with minimal pressure.
If the Sander is not removing enough material,
try a grittier piece of sandpaper. If you want to
remove a lot of material fast, use a belt sander.
38('6 All sanders leave sanding marks on the
workpiece. To minimize sanding marks, always
try to sand with the grain of the wood.
6. Occasionally stop the tool and empty the
Dust Box and check the sandpaper for tears,
wear, or fraying. Replace if necessary.
7. To prevent accidents, turn off the tool and
unplug it after use. Empty Dust Box and clean
tool. Store indoors out of children’s reach.

Troubleshooting
)/8\+', )8;;<\+'$_*=;'; J<Y'+?$%8+=(<8-;
Tool will not start. 1. Cord not connected.
2. No power at outlet.
3. Tool’s thermal reset breaker
tripped (if equipped).
4. Internal damage or wear.
(Carbon brushes or
Switch, for example.)
1. Check that cord is plugged in.
2. Check power at outlet. If outlet is unpowered,
turn off tool and check circuit breaker.
If breaker is tripped, make sure circuit is right
capacity for tool and circuit has no other loads.
3. Turn off tool and allow to cool.
Press reset button on tool.
4. Have technician service tool.
Tool operates slowly. 1. Forcing tool to work too fast.
2. Extension cord too long or cord
diameter too small.
1. Allow tool to work at its own rate.
2. Eliminate use of extension cord. If an extension
cord is needed, use one with the proper diameter
for its length and load. See Extension Cords
in Guard Plate Bolt section on page 4.
Performance
decreases over time.
Carbon brushes worn or damaged. Have qualified technician replace brushes.
Excessive noise
or rattling.
Internal damage or wear. (Carbon
brushes or bearings, for example.)
Have technician service tool.
Overheating. 1. Forcing tool to work too fast.
2. Blocked motor housing vents.
3. Motor being strained by long or
small diameter extension cord.
1. Allow tool to work at its own rate.
2. Wear ANSI-approved safety goggles and
NIOSH-approved dust mask/respirator while
blowing dust out of motor using compressed air.
3. Eliminate use of extension cord. If an extension
cord is needed, use one with the proper diameter
for its length and load. See Extension Cords
in Guard Plate Bolt section on page 4.
