GENERAL SAFETY INSTRUCTIONS
WARNING! Read all safety warnings and
all 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 mainsoperated (corded) power tool or
battery-operated (cordless) power tool.
1) WORK AREA SAFETY
a. Keep work area clean and well lit. Cluttered
or dark areas invite accidents.
b. 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.
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 earthed
(grounded) power tools.
Unmodified plugs and matching outlets will
reduce risk of electric shock.
b. 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.
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 extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces
the risk of electric shock.
f. If operating a power tool in a damp
location is unavoidable, use an earth
leakage circuit breaker. Use of an earth
leakage circuit breaker reduces the risk of
electric shock.
3) PERSONAL SAFETY
a. a) Stay alert, watch what you are doing and
use common sense when operating 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.
b. 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 off-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 accidents.
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

4
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.
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 off. 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 adjustments,
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 binding of moving parts,
breakage of parts and any other condition
that may affect the power tool’s 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 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.
5) SERVICE

Safety Warnings Common for
Grinding Operations:
a. This power tool is intended to function as
a grinder. Read all safety warnings,
instructions, illustrations and
specifications provided with this power
tool. Failure to follow all instructions listed
below may result in electric shock, fire and/or
serious injury.
b. Operations such as sanding, wire
brushing, polishing or cutting-off 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 fly 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. The arbour size of wheels, flanges, backing
pads or any other accessory must properly
fit the spindle of the power tool.
Accessories with arbour holes 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 flying debris
generated by various operations . The dust
mask or respirator must be capable of
filtrating 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 fly 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 could give the operator an
electric shock.
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. 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.

6
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.
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. Always use
auxiliary handle, if provided, for maximum
control over kickback or torque reaction
during start-up. 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 SPECIFIC FOR
GRINDING AND ABRASIVE CUTTING-
OFF 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 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, accidental contact
with wheel and sparks that could ignite
clothing.
c. Wheels must be used only for
recommended applications. For example:
do not grind with the side of cut-off wheel.
Abrasive cut-off wheels are intended for
peripheral grinding, side forces applied to
these wheels may cause them to shatter.
d. Always use undamaged wheel flanges that
are of correct size and shape for your
selected wheel. Proper wheel flanges
support the wheel thus reducing the
possibility of wheel breakage. Flanges for cut-
off wheels may be different from grinding
wheel flanges.
e. 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.
ELECTRICAL CONNECTION
The network voltage must conform to the

7
voltage indicated on the tool name plate.
Under no circumstances should the tool be
used when the power supply cable is damaged.
A damaged cable must be replaced
immediately by an authorized Customer Service
Center. Do not try to repair the damaged cable
yourself. The use of damaged power cables can
lead to an electric shock.
WARNING: Never operate a damaged
machine. Always tag a damaged machine and
take it out of service until repairs can be
made.

Motor and Electrical Requirements
WARNING: To reduce the risk of electrical
hazards, fire hazards or damage to the tool, use
proper circuit protection. To reduce the risk of
shock or fire, if the power cord is worn or cut, or
damaged in any way, have it replaced
immediately.
ELECTRICAL CONNECTIONS
NOTE: The plug supplied on your tool may not fit
into the outlet you are planning to use. Your local
electrical code may require slightly different power
cord plug connections. If these differences exist
refer to and make the proper adjustments per your
local code before your tool is plugged in and
turned on. In the event of a malfunction or
breakdown, grounding provides a path of least
resistance for electric current to reduce the risk of
electric shock. This tool is equipped with an
electric cord that has equipment grounding
conductor and a grounding plug. The plug must be
plugged into a matching outlet that is properly
installed and grounded in accordance with all local
codes and ordinances. Do not modify the plug
provided. If it will not fit the outlet, have the proper
outlet installed by a qualified electrician.
Improper connection of the equipment-grounding
conductor can result in a risk of electric shock. The
conductor with insulation has an outer surface that
is green with or without yellow stripes is the
equipment-grounding conductor. If repair or
replacement of the electric cord or plug is
necessary, do not connect the equipment-
grounding conductor to a live terminal.
If the power cord is worn or cut, or damaged in any
way, have it replaced immediately by a qualified
electrician. If the grounding instructions are not
completely understood, or if you are in doubt as to
whether the tool is properly grounded check with
a qualified electrician or service personnel.
WARNING: Do not permit fingers to touch the
terminals of plug when installing or removing
the plug from the outlet to avoid injury or
possible death from electrical shock.
WARNING: If not properly grounded, this tool
can cause an electrical shock, particularly when
used in damp locations, in proximity to
plumbing, or outdoors. If an electrical shock
occurs there is the potential of a secondary
hazard, such as your hands contacting the
milling head.
MOTOR SAFETY PROTECTION
IMPORTANT: To avoid motor damage, this
motor should be blown out or vacuumed
frequently to keep dust from interfering with
normal motor ventilation.
1. Connect this tool to a power source with the
appropriate voltage for your model.
2. If the motor won’t start, turn the switch “OFF”
immediately and unplug the tool.
3. If the motor suddenly stalls while milling,
release the trigger switch and unplug the
tool. The motor may now be restarted.
4. Fuses may "blow" or circuit breakers may trip
frequently for the following reasons:
a. Motor Is Overloaded - Overloading
can occur if you make too many start/
stops in a short time.
b. Line voltages should not be more than
10% above or below the nameplate
voltage. For heavy loads, however, the
voltage at motor terminals must equal
the voltage specified for your model.
Improper or dull milling head is being
used.
5. Most motor troubles may be traced to loose
or incorrect connections, overload, low
voltage, (such as small size wire in the supply
circuit) or to an overly long supply circuit
wire. Always check the connections, the load
and the supply circuit whenever motor
doesn’t work well. Check wire sizes and
length with the Wire Size Chart.

10
WIRE SIZES
NOTE: Make sure the proper extension cord is used
and is in good condition. Use only 3-wire extension
cords that have 3-prong grounding plugs and
3-pole receptacles that accept the tool’s plug. The
use of any extension cord will cause some loss of
power. To keep this to a minimum and to prevent
overheating and motor burnout, use the table on
Page 8 to determine the minimum wire size (A.
W.G.) extension cord.
UNPACKING
WARNING: To reduce the risk of injury from
unexpected starting or electrical shock, do not
plug the power cord into a power source outlet
during unpacking and assembly. The cord must
remain unplugged whenever you are working
on the tool.
Your tool is shipped complete in one box.
Remove the tool and all loose parts from the
carton.

THE EDGE CUT-OUT
When working against a wall or into a corner, the
Depth Shroud Base will prevent the grinding head
from reaching all the way to the edge. In this case,
one may remove the 3 knobs and remove the
entire Depth Shroud Base. This will expose the
Edge Cut-Out Door in the right side of the
Gearcase. This will allow the accessory Diamond
Grinding Head or TC Grinding Head to reach right
up to the edge. (When using the standard Scarifier
Wheel, it will not be possible to reach all the way to
the edge) Dust collection will not be ideal and
depth adjustment will not be possible with the
Shroud Base removed, so replace it as soon as
access to the Edge Cut-Out Door is no longer
needed.

REPLACING CARBON BRUSHES
The carbon brushes are a normal wearing part and
must be replaced when they reach their wear limit.
CAUTION: Always replace the brushes as a pair.
To replace:
Remove the four screws and remove tail cover.
Using pliers, rotate the brush spring out of the way
and slide old carbon brush out of the brush holder.
Unscrew the screw to remove the brush lead. The
old carbon brush many now be lifted away.
Install a new brush. Installation is the reverse of
removal.
Replace the motor tail cover.
NOTE: To reinstall the same brushes, first make
sure the brushes go back in the way they came out.
Otherwise a break-in period will occur that will
reduce motor performance and increase brush
wear. It is recommended that, at least once a year,
you take the tool to an Authorized Service Center
for a thorough cleaning and lubrication.
MAINTENANCE
WARNING: To reduce the risk of injury from
unexpected starting or electrical shock, unplug the
power cord before working on the machine.
Keep the tool clean. Remove accumulated dust
from working parts. Make sure that the tool
operates properly. Periodically check screws and
bolts for tightness.
KEEPING TOOL CLEAN
Keep the machine and air inlet louver clean at all
times to ensure correct and safe working. Under
extreme application conditions involving metal,
dust can enter the interior of the machine. The
protective insulation of the machine can be
adversely affected. In such cases the machine
should be blown out regularly though the air inlet
louver. It is recommended that a vacuum
attachment be used.
WARNING: To ensure safety and reliability, all
repairs, with the exception of externally accessible
brushes, should be performed at an Authorized
Service Center.

TOOL STORAGE
IMPORTANT: When the Power Scouring Machine is
not being used DO NOT leave it resting on the
Extraction/Shroud base plate or on the motor (tail
cover)
WARNING: If the replacement of the power
supply cord is necessary, this has to be done
by the manufacturer or their agent in order
to avoid a safety hazard.
Do not throw electric power tools into the
household waste! In accordance with the European
Directive 2002/96/EG on Waste Electrical and
Electronic Equipment and transposition into
national law, used electric power tools must be
collected separately and recycled in an
environmentally friendly manner.
