General Power Tool Safety Warnings
WARNING
!
Read all safety warnings and instructions. Failure to follow the warnings
and instructions may result in electric shock, fire 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) power tool or
battery-operated (cordless) power tool.
Work area safety
Keep work area clean and well lit. Cluttered
or dark areas invite accidents.
Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. Power
tools create sparks which may ignite the dust
or fumes.
Keep children and bystanders away while
operating a power tool. Distractions can
cause you to lose control.
Electrical safety
Power tool plugs must match the outlet.
Never modify the plug in any way. Do not
us e a ny adapter pl ug s with earthe d
(grounded) power tools. Unmodified plugs
and matching outlets will reduce risk of electric
shock.
Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased risk
of electric shock if your body is earthed or
grounded.
Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
Do not abuse the cord. Never use the cord
for carrying, pulling or unplugging the power
tool. Keep cord away from heat, oil, sharp
edges or moving parts. Damaged or entangled
cords increase the risk of electric shock.
When operating a power tool 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 the power tool in damp locations
is unavoidable, use a Ground Fault Circuit
Interrupter (GFCI) protected supply. Use of
an GFCI reduce the risk of electric shock.
Personal safety
Stay alert, watch what you are doing and
us e co mmon sense w hen opera ting a
power tool. Do not use a power tool while
you are tired or under the influence of drugs,
alcohol or medication. A moment of inattention
while operating power tools may result in
serious personal injury.
Use personal protective equipment. Always
wear eye protection. Protective equipment
such as dust mask, non-skid safety shoes, hard
hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
Prevent unintentional starting. Ensure the
sw itch is in th e o ff-po sitio n b efore
connecting to power source and / or battery
pa ck, picki ng up or carrying the t ool.
Carrying power tools with your finger on the
switch or energizing power tools that have the
switch on invites accidents.
Remove any adjusting key or wrench before
turning the power tool on. A wrench or a
key left attached to a rotating part of the
power tool may result in personal injury.
Do not overreach. Keep proper footing and
balance at all times. This enables better
co ntrol of the power to ol in unexpe ct ed
situations.
Dress properly. Do not wear loose clothing
or jewelry. Keep your hair, clothing and
gloves away from moving parts. Loose
clothes, jewelry or long hair can be caught in
moving parts.
If devices are provided for the connection
of dust extraction and collection facilities,
ensure these are connected and properly
used. Use of dust collection can reduce dust-
related hazards.
Power tool use and care
Do not forc e the power to ol. Use the
correct power tool for your application. The
correct power tool will do the job better and
safer at the rate for which it was designed.
Do not use the power tool if the switch does
not turn it on and off. Any power tool that
ca nn ot be co nt ro ll ed wi th th e swi tc h is
dangerous and must be repaired.

Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
Store idle power tools out of the reach of
child ren and do n ot allow perso ns
unfamiliar with the power tool or these
instructions to operate the power tool.
Power tools are dangerous in the hands of
untrained users.
Maintain power tools. Check for misalignment
or binding of moving parts, breakage of
parts and any other condition that may
affect the power tool’s o per ati on. I f
damaged, have the power tool repaired
before use. Many accidents are caused by
Safety Rules for Orbital Sanders
Hold power tools by insulated gripping
surfaces when performing an operation
where the cutting tool may contact hidden
wiring or its own cord. Contact with a "live"
wire will make exposed metal parts of the tool
"live" and shock the operator.
Unplug the san de r bef or e cha ng in g
accessories. Accidental start-ups may occur
if sander is plugged in while changing an
accessory.
Use clamps or another practical way to
secure and support the workpiece to a
stable platform. Holding the work by hand
or against your body leaves it unstable and
may lead to loss of control.

completion of sanding and before storing
the sander. Be extremely careful of dust
disposal, materials in fine particle form may
be explosive. Do not throw sanding dust on
an open fire. Combustion from mixture of
varnishes, lacquers, polyurethane, oil or
water with dust particles can occur if there is
a static discharge, spark introduced in the
box, or excessive heat.
poorly maintained power tools.
Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to
control.
Use the power tool, accessories and tool
bits etc. in accordance with these instructions,
taking into account the working conditions
and the work to be performed. Use of the
power tool for operations different from those
intended could result in a hazardous situation.
Service
Have your power tool serviced by a qualified
re pa ir pers on using on ly identi ca l
replacement parts. This will ensure that the
safety of the power tool is maintained.
Always wear eye protection and a dust
mask for dusty applications a nd when
sanding overhead. Sanding particles can be
absorbed by your eyes and inhaled easily
and may cause health complications.
Use special precautions when sanding
chemically pressure treated lumber, paint
th at may be lea d base d, or any other
materials that may contain carcinogens. A
suitable breathing respirator and protective
clothing must be worn by all persons entering
the work area. Work area should be sealed
by p la stic s heeting and pe rsons not
protected should be kept out until work area
is thoroughly cleaned.
Do not wet sand with this sander. Liquids
entering the motor housing is an electrical
shock hazard.
Do not use sandpaper intended for larger
sanding pads. Larger sandpaper will extend
beyond the sanding pad causing snagging,
tearing of the paper or kick-back. Extra paper
extending beyond the sanding pad can also
cause serious lacerations.

Tool Tips
This tool is particularly suitable for one hand ed
operation, and access to corners and edges
that are otherwise difficult to reach and require
hand sanding. Profiles and grooves may be fin ished using the tip or edge of the selected
attachment, which should occasionally be
rotated during use to distribute the wear on the
attachment and backing pad surface.
Always be certain that smaller workpieces are
securely fastened to a bench or other support.
Larger panels may be held in place by hand on
a bench or sawhorses.
SANDING: Open-coat aluminum oxide sanding
sheets are recommended for most wood or
metal sand ing applications, as this synthetic
material cuts quickly and wears well. Some
ap plica tions , such as me ta l fin ishing or
cleaning, require spe cial abrasive pads which
are available from your dealer. For best results,
use sanding and polishing accessories which
ar e of sup erior quality a nd a re c arefu lly
selected to produce professional quality results
with your sander.
The following suggestions may be used as a
gen eral guide for abrasive selection, but the
best re sults will be obtained by sanding a test
sample of the workpiece first.
Grit
Coarse For rough wood or metal sanding,
Medium For general wood or metal sanding
Fine For final finishing of wood, metal,
Extra fine For final sanding of bare wood,
With the workpiece firmly secured, turn tool on
as described above. Contact the work with the
tool after the sander has reached its full speed,
and remove it from the work before switching
the tool off. Operating your sander in this
manner will pro long switch and motor life, and
greatly increase the quality of your work.

overlap the strokes by as much as 75%. DO
NOT apply exces sive pressure — let the tool
do the work. Ex cessive pressure will result in
poor handling, vibration, and unwanted sanding
marks (Fig. 10).
FIG. 10
If the surface is rough, begin with coarser grits
and then complete the surfacing with medium
and fine abra sives. To avoid uneven results, do
not skip more than one grit size when going
from coarser to finer, and do not sand in one
area for too long. When the job is completed,
gently lift the tool from the work surface and
slide switch to the "OFF" position.
POLISHING: Your Multi-finishing sander may
be fit ted with option al abrasive mes h or
polishing pads to polish or remove scratches or
co rrosi on from meta l, pain ted, or oth er
surfaces. The tool is oper ated in much the
same way as when sanding, but the following
points should be observed;
Use light pressure and a circular or overlapping
mo tion to remove scratches and corrosion or
pol ish a surface. If using a compound, use only
as much as necessary and do not use the dust
ex trac tion feature.
Wh en working in v ery confi ned areas o r
louvered pa nels, the pad extension plate
should be used.
Clean the buffing or mesh pads with mild deter gents and warm water. DO NOT use solvents.
