SANDING OPERATIONS
Selecting Sanding Disc
Sanding discs are made of extremely hard and sharp aluminum
oxide grits, phenol-resin bonded to a sturdy ber backing for fast
heavy-duty service and long life. The discs vary as to size and
spacing of the abrasive grits. OPEN COAT(type H) ― used for
soft materials and on paint or varnish. CLOSED COAT (type K) ―
used for metal, hardwood, stone, marble and other materials.
Sanding discs range in grit from 16 (very coarse) to 180
(very ne). To obtain best results, select sanding discs carefully.
Many jobs require the use of several grit sizes and at times both
“open coat and closed coat” discs are required to get the job done
faster. See chart for application examples.
Operation: Renishing painted wood or metal surfaces.

SANDING TIPS
For best results, tilt the Disc Sander at a 10° to 15° angle while
sanding so that only about 1” of the surface around the edge of
the disc contacts the work.
WARNING!
If the disc (accessory) is held at or the back edge of the disc
comes in contact with the work,a violent thrust to the side may
result.
If sander is tilted too much, sanding action will be too great and a
rough cut surface or gouging and snagging will result. Guide the
Disc Sander with crosswise strokes. Be careful not to hold the
sander in one spot too long. Do not use a circular motion, as this
makes swirl marks. Test before use on scrap stock.
Do not force or apply pressure when sanding. Use only the weight
of the tool for pressure. Excess pressure actually slows the tool
down. If faster stock removal is desired, change to a coarser grit
disc.
Remove gummy paint from metal with an “open coat” disc. Sand
until sparks start to appear, then stop and change to a “closed
coat” disc to remove any remaining paint.
SANDING WOOD
When sanding wood the direction of the disc motion at the contact
point should parallel the grain as much as possible. The rapid cut
of discs and the swirl type scratch pattern they occasionally cre-
ate generally prohibit their use for producing the nal nish.
Scratches and circular marks are usually the result of using too
coarse a grit. When changing to a finer grit, move across the
sanding lines that were made by a previous coarser disc.
SANDING METAL
When sanding automobiles or appliances, wipe the metal clean
with a non-ammable solvent or commercial cleaner to remove
all wax and grease. By doing this rst, the sanding discs will sand
better and last longer.
For heavy duty work, use a coarse grit disc rst. Follow-up with a
medium grit to remove scratches. To produce smooth nish, use
ne grit disc.
MAINTENANCE
After use, check the tool to make sure that it is in top condition.
It is recommended that you take this tool to an Authorized Ser-
vice Center for a thorough cleaning and lubrication at least once
per year.
DO NOT MAKE ANY ADJUSTMENTS WHILE THE MOTOR IS
IN MOTION.
ALWAYS DISCONNECT THE POWER CORD FROM THE
RECEPTACLE BEFORE CHANGING REMOVABLE OR EX-
PENDABLE PARTS (BLADE, BIT, SANDING PAPER ETC.),
LUBRICATING OR WORKING ON THE UNIT.

Kickback is the result of power tool misuse and/or incorrect
operating procedures or conditions and can be avoided by
taking proper precautions as given below.
a) Maintain a firm grip on the power tool and position
your body and arm to allow you to resist kickback
forces. The operator can control torque reactions or
kickback forces, if proper precautions are taken.
b) Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
c) Do not position your body in the area where power
tool will move if kickback occurs. Kickback will propel
the tool in direction opposite to the wheel’s movement at
the point of snagging.
d) Use special care when working corners, sharp edges
etc. Avoid bouncing and snagging the accessory.
Corners, sharp edges or bouncing have a tendency to
snag the rotating accessory and cause loss of control or
kickback.
e) Do not attach a saw chain woodcarving blade or
toothed saw blade. Such blades create frequent kickback
and loss of control.
Safety Warnings Specic for Grinding Operations:
a) Use only wheel types that are recommended for your
power tool and the specific guard designed for the
selected wheel. Wheels for which the power tool was not
designed cannot be adequately guarded and are unsafe.
b) The grinding surface of centre depressed wheels
must be mounted below the plane of the guard lip. An
improperly mounted wheel that projects through the plane
of the guard lip cannot be adequately protected.
c) The guard must be securely attached to the power
tool and positioned for maximum safety, so the least
amount of wheel is exposed towards the operator. The
guard helps to protect the operator from broken wheel
fragments, and sparks that could ignite clothing. accidental
contact with wheel.
d) Wheels must be used only for recommended
applications. For example: do not grind with the side
of cut-o wheel. Abrasive cut-o wheels are intended for
peripheral grinding, side forces applied to these wheels
may cause them to shatter.
e) Always use undamaged wheel flanges that are of
correct size and shape for your selected wheel.
Proper wheel anges support the wheel thus reducing the
possibility of wheel breakage.
f) Do not use worn down wheels from larger power tools.
Wheel intended for larger power tool is not suitable for the
higher speed of a smaller tool and may burst.
Safety Warnings Specic for Sanding Operations:
a) Do not use excessively oversized sanding disc paper.
Follow manufacturers recommendations, when
selecting sanding paper. Larger sanding paper extending
beyond the sanding pad presents a laceration hazard and
may cause snagging, tearing of the disc or kickback.
Safety Warnings Specic for Polishing Operations:
a) Do not allow any loose portion of the polishing bonnet
or its attachment strings to spin freely. Tuck away or
trim any loose attachment strings. Loose and spinning
attachment strings can entangle your ngers or snag on
the workpiece.
INSTRUCTIONS FOR SAFE HANDLING
1. Make sure that the tool is only connected to the voltage
marked on the rating plate.
2. Never use the tool if its cover or any bolts are missing. If the
cover or bolts have been removed, replace them prior to use.

General Power Tool Safety Warnings
WARNING! Read all safety warnings, instructions, illustra-
tions and specications provided with this power tool. Failure
to follow all instructions listed below 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 corded or
battery-operated (cordless) power tool.
1) Work area safety
a) Keep work area clean and well lit. Cluttered or dark ar-
eas invite accidents.
b) Do not operate power tools in explosive atmospheres,
such as in the presence of ammable liquids, gases or
dust. Power tools create sparks which may ignite the dust
or fumes.
c) Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
2) Electrical safety
a) Power tool plugs must match the outlet. Never modify
the plug in any way. Do not use any adapter plugs with
grounded power tools. Unmodied plugs and matching
outlets will reduce risk of electric shock.
b) Avoid body contact with grounded surfaces such as
pipes, radiators, ranges and refrigerators. There is an
increased risk of electric shock if your body is grounded.
c) Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric
shock.
d) 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.
e) When operating a power tool outdoors, use an exten-
sion cord suitable for outdoor use. Use of a cord suit-
able for outdoor use reduces the risk of electric shock.
f) If operating a power tool in a damp location is un-
avoidable, use a ground fault circuit interupter
(GFCI) pro-tected supply. Use of an GFCI reduces the
risk of electric shock.
3) Personal safety
a) Stay alert, watch what you are doing and use com-
mon sense when operating a power tool. Do not use a
power tool while you are tired or under the inuence
of drugs, alcohol or medication. A moment of inattention
while operating power tools may result in serious personal
injury.
b) 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.
c) Prevent unintentional starting. Ensure the switch is
in the o-position before connecting to power source
and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or
energising power tools that have the switch on invites ac-
cidents.
d) 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.
e) Do not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situations.
f) 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.
g) 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.
h) Do not let familiarity gained from frequent use of tools
allow you to become complacent and ignore tool safe-
ty principles. A careless action can cause severe injury
within a fraction of a second.
4) Power tool use and care
a) Do not force the power tool. 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.
b) Do not use the power tool if the switch does not turn it
on and o. Any power tool that cannot be controlled with the
switch is dangerous and must be repaired.
c) Disconnect the plug from the power source and/or the
battery pack from the power tool before making any ad-
justments, changing accessories, or storing power tools.
Such preventive safety measures reduce the risk of starting
the power tool accidentally.
d) Store idle power tools out of the reach of children and do
not allow persons unfamiliar with the power tool or these
instructions to operate the power tool. Power tools are
dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalignment or bind-
ing of moving parts, breakage of parts and any other
condition that may affect the power tools operation. If
damaged, have the power tool repaired before use. Many
accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained
cutting tools with sharp cutting edges are less likely to bind
and are easier to control.
g) Use the power tool, accessories and tool bits etc. in ac-
cordance with these instructions, taking into account the
working conditions and the work to be performed. Use
of the power tool for operations dierent from those intended
could result in a hazardous situation.
h) Keep handles and grasping surfaces dry, clean and free
from oil and grease. Slippery handles and grasping surfaces
do not allow for safe handling and control of the tool in unex-
pected situations.
5) Service
a) Have your power tool serviced by a qualified repair
person using only identical replacement parts. This will
ensure that the safety of the power tool is maintained.
Safety Warnings Common for Grinding, Sanding
or Polishing Operations:
a) This power tool is intended to function as a grinder,
sander or polisher tool. Read all safety warnings,
instructions, illustrations and specications provided
with this power tool. Failure to follow all instructions
listed below may result in electric shock, re and/or serious
injury.
b) Operation such as wire brushing or cutting-o are not
recommended to be performed with this power tool.
Operations for which the power tool was not designed may
create a hazard and cause personal injury.
c) Do not use accessories which are not specifically
designed and recommended by the tool manufacturer.
Just because the accessory can be attached to your power
tool, it does not assure safe operation.
d) The rated speed of the accessory must be at least
equal to the maximum speed marked on the power
tool. Accessories running faster than their rated speed can
break and y apart.
e) The outside diameter and the thickness of your
accessory must be within the capacity rating of your
power tool. Incorrectly sized accessories cannot be
adequately guarded or controlled.
f) Threaded mounting of accessories must match the
grinder spindle thread. For accessories mounted by
anges, the arbour hole of the accessory must t the
locating diameter of the ange. Accessories that do not
match the mounting hardware of the power tool will run
out of balance, vibrate excessively and may cause loss of
control.
g) Do not use a damaged accessory. Before each use
inspect the accessory such as abrasive wheels for
chips and cracks, backing pad for cracks, tear or
excess wear, wire brush for loose or cracked wires.
If power tool or accessory is dropped, inspect for
damage or install an undamaged accessory. After
inspecting and installing an accessory, position
yourself and bystanders away from the plane of the
rotating accessory and run the power tool at maximum
no-load speed for one minute. Damaged accessories will
normally break apart during this test time.
h) Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety
glasses. As appropriate, wear dust mask, hearing
protectors, gloves and workshop apron capable of
stopping small abrasive or workpiece fragments. The
eye protection must be capable of stopping ying debris
generated by various operations . The dust mask or
respirator must be capable of ltrating particles generated
by your operation. Prolonged exposure to high intensity
noise may cause hearing loss.
i) Keep bystanders a safe distance away from work area.
Anyone entering the work area must wear personal
protective equipment. Fragments of workpiece or of a
broken accessory may y away and cause injury beyond
immediate area of operation.
j) Hold the power tool by insulated gripping surfaces
only, when performing an operation where the cutting
accessory may contact hidden wiring or its own cord.
Cutting accessory contacting a “live” wire may make
exposed metal parts of the power tool “live” and shock the
operator.
k) Position the cord clear of the spinning accessory. If
you lose control, the cord may be cut or snagged and your
hand or arm may be pulled into the spinning accessory.
l ) Never lay the power tool down until the accessory has
come to a complete stop. The spinning accessory may
grab the surface and pull the power tool out of your control.
m) Do not run the power tool while carrying it at your side.
Accidental contact with the spinning accessory could snag
your clothing, pulling the accessory into your body.
n) Regularly clean the power tool’s air vents. The motor’s
fan will draw the dust inside the housing and excessive
accumulation of powdered metal may cause electrical
hazards.
o) Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
p) Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in
electrocution or shock.
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or snagged rotating
wheel, backing pad, brush or any other accessory. Pinching or
snagging causes rapid stalling of the rotating accessory which
in turn causes the uncontrolled power tool to be forced in the
direction opposite of the accessory’s rotation at the point of the
binding.
For example, if an abrasive wheel is snagged or pinched by the
workpiece, the edge of the wheel that is entering into the pinch
point can dig into the surface of the material causing the wheel
to climb out or kick out. The wheel may either jump toward or
away from the operator, depending on direction of the wheel’s
movement at the point of pinching. Abrasive wheels may also
break under these conditions.

OPERATION
SLIDE ON-OFF SWITCH WITH LOCK (Fig. 3)
The tool is switched “ON” by the switch button located at the
top of the motor housing. The switch can be locked in the
“ON” position, a convenience for long grinding operations.
To turn the tool “ON” without locking it, slide the switch button
forward by applying pressure ONLY at the REAR portion of the
button. When pressure is released the switch button will snap to
“OFF” position.
To lock the switch “ON”, slide the switch button forward and press
“IN” the FRONT portion.
To unlock the switch, simply press and release the REAR portion
of the button. Switch is spring loaded and will snap back automati-
cally.
WARNING!
Hold the tool with both hands while starting the tool, since torque
from the motor can cause the tool to twist.
Start the tool before applying to work and let the tool come to full
speed before contacting the workpiece. Lift the tool from the work
before releasing the switch. DO NOT turn the switch “ON” and
“OFF” while the tool is under load; this will greatly decrease the
switch life.
GRINDING OPERATION
Selecting Grinding Wheels
WARNING!
Before using a grinding wheel, be certain that its maximum safe
operating speed is not exceeded by the nameplate speed of the
grinder. Do not exceed the recommended wheel diameter.
Disc Grinding Wheels
Grinding wheels should be carefully selected in order to use the
grinder most efficiently. Wheels vary in type of abrasive, bond,
hardness, grit size and structure. The correct type of wheel to use
is determined by the job. Use disc grinding wheels for fast grind-
ing of structural steel, heavy weld beads, steel casting, stainless
steel and other ferrous metals.
Grinding Tips
Efficient grinding is achieved by controlling the pressure and
keeping the angle between wheel and workpiece at 10° to 15°. If
the wheel is at, the tool is dicult to control. If the angle is too
steep, the pressure is concentrated on a small area causing burn-
ing to the work surface.
WARNING!
Excessive or sudden pressure on the wheel will slow grinding ac-
tion and put dangerous stresses on the wheel.
When grinding with a new wheel be certain to grind while pulling
tool backwards until wheel becomes rounded on its edge. New
wheels have sharp corners which tend to “bite” or cut into work-
piece when pushing forward.
