General Power Tool Safety
Warnings
WARNING Read all safety
warnings and instructions.
Failure to follow the warnings and
instructions may result in electric
shock, re and/or serious injury.
Save all warnings and
instructions for future reference.
The term ″power tool″ in the
warnings refers to your mains-
operated (corded) Compact Belt
Sander.
Work area safety:1.
Keep work area clean and well lit.a.
Cluttered or dark areas invite acci-
dents.
Do not operate this Compact Beltb.
Sander in explosive atmospheres,
such as in the presence of amma-
ble liquids, gases or dust. Power
tools create sparks which may ignite
the dust or fumes.
Keep children and bystandersc.
away while operating this Compact
Belt Sander. Distractions can cause
you to lose control.
Electrical safety:2.
Power tool plugs must match thea.
outlet. Never modify the plug in
any way. Do not use any adapter
plugs with grounded power tools.

SKU 66891 For technical questions, please call 1-800-444-3353. Page 4
Unmodied plugs and matching out-
lets will reduce risk of electric shock.
NOTE: This Compact Belt Sander has a
2-Prong Power Cord plug.
Avoid body contact with groundedb.
surfaces such as pipes, radiators,
ranges and refrigerators. There is
an increased risk of electric shock if
your body is grounded.
Do not expose power tools to rainc.
or wet conditions. Water entering
this Compact Belt Sander will in-
crease the risk of electric shock.
Do not abuse the cord. Neverd.
use the cord for carrying, pulling
or unplugging this Compact Belt
Sander. Keep the cord away from
heat, oil, sharp edges or moving
parts. Damaged or entangled cords
increase the risk of electric shock.
When operating this Compact Belte.
Sander outdoors, use an extension
cord suitable for outdoor use. Use
of a cord suitable for outdoor use
reduces the risk of electric shock.
If operating this Compact Beltf.
Sander in a damp location is un-
avoidable, use a Ground Fault
Circuit Interrupter (GFCI) protected
supply. Use of a GFCI reduces the
risk of electric shock.
Specic Personal safety Rules:3.
Stay alert, watch what you are do-a.
ing and use common sense when
operating this Compact Belt Sand-
er. Do not use while you are tired
or under the inuence of drugs,
alcohol or medication. A moment
of inattention while operating power
tools may result in serious personal
injury.
Use personal protective equip-b.
ment. Always wear ANSI-approved
safety eye protection and a dust-
mask/respirator. Safety equipment
such as non-skid safety shoes, a
hard hat, or hearing protection used
for appropriate conditions will reduce
personal injuries.
Do not allow children to use thisc.
Compact Belt Sander. This power
tool is not a toy and should not be
operated by any child, or untrained
user, at any time.
Severe abrasion hazard.d. Keep
hands and ngers clear of moving
sanding belts, and do not let your
ngers rest over the front or right
edge of the Compact Belt Sander. If
the sanding belt should run off, or if
it is not properly adjusted, your n-
gers could come in contact with the
moving belt possibly causing serious
personal injury.
Severe pinching hazard.e. Keep
hands and ngers clear of front roller
at all times. Failure to do so may
result in ngers being pinched and/or
other personal injury.
WARNING! To reduce the risk of injury,

better and safer at the rate for which
it was designed.
Do not use this Compact Beltb.
Sander if the switch does not turn
it on and off. Any power tool that
cannot be controlled with the switch
is dangerous and must be repaired.
Disconnect the plug from thec.
power source before making any
adjustments, changing accesso-
ries, or storing. Such preventive
safety measures reduce the risk of
accidental starting.
Avoid unintentional starting.d. Pre-
pare to begin work before turning on
the Compact Belt Sander.
Do not lay the Compact Belte.
Sander down until it has come to
a complete stop. Moving parts can
grab the surface and pull the tool out
of your control.

GROUNDING
TO PREVENT
ELECTRIC SHOCK
AND DEATH FROM
INCORRECT GROUNDING
WIRE CONNECTION:
Check with a qualied
electrician if you are in doubt
as to whether the outlet is
properly grounded. Do not
modify the power cord plug
provided with the tool. Never
remove the grounding prong
from the plug. Do not use the
Compact Belt Sander if the
power cord or plug is
damaged. If damaged, have it
repaired by a service facility
before use. If the plug will not
t the outlet, have a proper
outlet installed by a qualied
electrician.

Double insulated tools may be used2.
in either of the 120 volt outlets shown
in the preceding illustration. (See
Outlets for 2-Prong Plug.)
Extension Cords
Grounded1. tools require a three wire
extension cord. Double Insulated
tools can use either a two or three
wire extension cord.
As the distance from the supply outlet2.
increases, you must use a heavier
gauge extension cord. Using exten-
sion cords with inadequately sized
wire causes a serious drop in voltage,
resulting in loss of power and pos-
sible tool damage.
(See Table A.)
The smaller the gauge number of the3.
wire, the greater the capacity of the
cord. For example, a 14 gauge cord
can carry a higher current than a 16
gauge cord. (See Table A.)
When using more than one exten-4.
sion cord to make up the total length,
make sure each cord contains at
least the minimum wire size required.
(See Table A.)
If you are using one extension cord5.
for more than one tool, add the
nameplate amperes and use the sum
to determine the required minimum
cord size. (See Table A.)
If you are using an extension cord6.
outdoors, make sure it is marked with
