GENERAL SAFETY RULES
WARNING:
Read all instructions. Failure to follow all
instructions listed below may result in electric
shock, fire and/or serious injury.
SAVE THESE INSTRUCTIONS
WORK AREA
Keep your work area clean and well lit. Cluttered
benches and 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 bystanders, children, and visitors away while
operating a power tool. Distractions can cause you to
lose control.
ELECTRICAL SAFETY
Double insulated tools are equipped with a polarized
plug (one blade is wider than the other). This plug will
fit in a polarized outlet only one way. If the plug does
not fit fully in the outlet, reverse the plug. If it still
does not fit, contact a qualified electrician to install a
polarized outlet. Do not change the plug in any way.
Double insulation
wire grounded power cord and grounded power supply
system.
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.
Don’t 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 to carry the
tools or pull the plug from an outlet. Keep cord away
from heat, oil, sharp edges, or moving parts. Replace
damaged cords immediately. Damaged cords increase
the risk of electric shock.
When operating a power tool outside, use an outdoor
extension cord marked “W-A” or “W”. These cords
are rated for outdoor use and reduce the risk of electric
shock.
PERSONAL SAFETY
Stay alert, watch what you are doing and use common
sense when operating a power tool. Do not use tool
while tired or under the influence of drugs, alcohol,
or medication. A moment of inattention while operating
power tools may result in serious personal injury.
Dress properly. Do not wear loose clothing or jewelry.
Contain long hair. Keep your hair, clothing, and gloves
away from moving parts. Loose clothes, jewelry, or long
hair can be caught in moving parts.
eliminates the need for the three-
Avoid accidental starting. Be sure switch is off
before plugging in. Carrying tools with your finger on the
switch or plugging in tools that have the switch on invites
accidents.
Remove adjusting keys or wrenches before turning
the tool on. A wrench or a key that is left attached to a
rotating part of the tool may result in personal injury.
Do not overreach. Keep proper footing and balance
at all times. Proper footing and balance enables better
control of the tool in unexpected situations.
Use safety equipment. Always wear eye protection.
Dust mask, nonskid safety shoes, hard hat, or hearing
protection must be used for appropriate conditions.
Do not wear loose clothing or jewelry. Contain long
hair. Loose clothes, jewelry, or long hair can be drawn
into air vents.
Do not use on a ladder or unstable support. Stable
footing on a solid surface enables better control of the
tool in unexpected situations.
TOOL USE AND CARE
Use clamps or other practical way to secure and
support the workpiece to a stable platform. Holding
the work by hand or against your body is unstable and
may lead to loss of control.
Do not force tool. Use the correct tool for your
application. The correct tool will do the job better and
safer at the rate for which it is designed.
Do not use tool if switch does not turn it on or off. Any
tool that cannot be controlled with the switch is dangerous and must be repaired.
Disconnect the plug from power source before making
any adjustments, changing accessories, or storing the
tool. Such preventive safety measures reduce the risk of
starting the tool accidentally.
Store idle tools out of the reach of children and other
untrained persons. Tools are dangerous in the hands of
untrained users.
Maintain tools with care. Keep cutting tools sharp
and clean. Properly maintained tools with sharp cutting
edges are less likely to bind and are easier to control.
Check for misalignment or binding of moving parts,
breakage of parts, and any other condition that may
affect the tool’s operation. If damaged, have the tool
serviced before using. Many accidents are caused by
poorly maintained tools.
Use only accessories that are recommended by the
manufacturer for your model. Accessories that may be
suitable for one tool, may become hazardous when used
on another tool.
Keep the tool and its handle dry, clean and free from
oil and grease. Always use a clean cloth when clean-
ing. Never use brake fluids, gasoline, petroleum-based
products, or any strong solvents to clean your tool. Following this rule will reduce the risk of loss of control and
deterioration of the enclosure plastic.

GENERAL SAFETY RULES
SERVICE
Tool service must be performed only by qualified
repair personnel. Service or maintenance performed by
unqualified personnel may result in a risk of injury.
SPECIFIC SAFETY RULES
This power tool is intended to function as a grinder,
sander, wire brush, or polisher. 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.
Operations such as 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.
Do not use accessories which are not specifically de-
signed and recommended by the tool manufacturer. Just
because the accessory can be attached to your power tool,
does not assure safe operation.
The rated speed of the accessory must be at least equal
to the maximum speed marked on the power tool. Ac-
cessories running faster than their RATED SPEED can break
and fly apart.
The outside diameter and the thickness of your acces-
sory must be within the capacity rating of your power
tool. Incorrectly sized accessories cannot be adequately
guarded or controlled.
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.
Do not use a damaged accessory. Before each use in-
spect 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.
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. he eye
protection must be capable of stopping flying debris
generated by various operations. 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.
Keep bystanders a safe distance away from work area.
When servicing a tool, use only identical replacement
parts. Follow instructions in the Maintenance section
of this manual. Use of unauthorized parts or failure to
follow Maintenance Instructions may create a risk of
shock or injury.
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.
Hold 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 ²live² wire may make exposed metal
parts of the power tool ²live² and shock the operator.
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.
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.
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.
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.
Do not operate the power tool near flammable materials.
Sparks could ignite these materials.
Do not use accessories that require liquid coolants. Using
water or other liquid coolants may result in electrocution or
shock.
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.
Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
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.
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.
Do not attach a saw chain woodcarving blade or toothed
saw blade. Such blades create frequent kickback and loss
of control.
Use only wheel types that are recommended for your
power tool and the specific guard designed for the
4 - English
SPECIFIC SAFETY RULES
selected wheel. Wheels for which the power tool was not
designed cannot be adequately guarded and are unsafe.
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 operator from broken wheel fragments and
accidental contact with wheel.
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.
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.
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.
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.
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 fingers or snag on the
workpiece.
Be aware that wire bristles are thrown by the brush even
during ordinary operation. Do not overstress the wires by
applying excessive load to the brush. The wire bristles
can easily penetrate light clothing and/or skin.
If the use of a guard is recommended for wire brushing,
do not allow any interference of the wire wheel or brush
with the guard. Wire wheel or brush may expand in diameter
due to work load and centrifugal forces.
Always use proper guard with grinding wheel. A guard
protects operator from broken wheel fragments.
Know your power tool. Read operator’s manual carefully.
Learn its applications and limitations, as well as the
specific potential hazards related to this tool. Following
this rule will reduce the risk of electric shock, fire, or serious
injury.
Always wear eye protection with side shields marked
to comply with ANSI Z87.1. Failure to do so could result
in objects being thrown into your eyes, resulting in possible
serious injury.
Protect your lungs. Wear a face or dust mask if the
operation is dusty. Following this rule will reduce the risk
of serious personal injury.
Protect your hearing. Wear hearing protectors during
extended periods of operation. Following this rule will
reduce the risk of serious personal injury.
Inspect tool cords periodically and, if damaged, have
repaired at your nearest authorized service center.
Constantly stay aware of cord location. Following this
rule will reduce the risk of electric shock or fire.
Check damaged parts. Before further use of the tool, a
guard or other part that is damaged should be carefully
checked to determine that it will operate properly and
perform its intended function. Check for alignment of
moving parts, binding of moving parts, breakage of parts,
mounting, and any other conditions that may affect its
operation. A guard or other part that is damaged should
be properly repaired or replaced by an authorized service
center. Following this rule will reduce the risk of shock, fire,
or serious injury.
Make sure your extension cord is in good condition.
When using an extension cord, be sure to use one heavy
enough to carry the current your product will draw. A
wire gauge size (A.W.G.) of at least 14 is recommended
for an extension cord 50 feet or less in length. A cord
exceeding 100 feet is not recommended. If in doubt, use
the next heavier gauge. The smaller the gauge number,
the heavier the cord. An undersized cord will cause a drop
in line voltage resulting in loss of power and overheating.
Inspect for and remove all nails from lumber before using
this tool. Following this rule will reduce the risk of serious
personal injury.
If the power supply cord is damaged, it must be replaced
only by the manufacturer or by an authorized service center
to avoid risk.
Save these instructions. Refer to them frequently and use
them to instruct others who may use this tool. If you loan
someone this tool, loan them these instructions also.
WARNING:
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals
known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
•leadfromlead-basedpaints,
•crystallinesilicafrombricksandcementandothermasonryproducts,and
•arsenicandchromiumfromchemically-treatedlumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure

To prevent loss of control and possible serious
injury, always operate the grinder with the side
handle installed.
OPERATING THE GRINDER
See Figure 8, page 16.
Always carefully select and use grinding wheels that are
recommended for the material to be ground. Make sure
that the operating speed of any accessory wheel selected is
rated at 10,000 r/min. or more. The grinding wheel provided
with the grinder is suitable for grinding welds, preparing
surfaces to be welded, grinding structural steel, and grinding stainless steel.
To operate the grinder:
Secure all work in a vise or clamp to a workbench.
DANGER:
Never use the grinder with the wheel guard
removed and always be sure the wheel guard is
locked into place. It has been designed for use
only with the wheel guard installed. Attempting to
use grinder with wheel guard removed will result in
loose particles being thrown against the operator
resulting in serious personal injury.
Hold the grinder in front and away from you with
both hands, keeping the grinding wheel clear of the
workpiece.
Turn on the grinder and let the motor and grinding wheel
build up to full speed.
Lower the grinder gradually until the grinding wheel con-
tacts the workpiece.
Keep the grinder tilted at an angle from 5 to 15 de-
grees.
WARNING:
To prevent loss of control and possible serious
personal injury, always operate the grinder
with both hands, keeping one hand on the side
handle.
Move the grinder continuously at a steady, consistent
pace.
CAUTION:
If the grinder is held in one spot too long, it will
gouge and cut grooves in the workpiece. If the
grinder is held at too sharp an angle, it will also
gouge the workpiece because of concentration of
pressure on a small area.
Use just enough pressure to keep the grinder from chat-
tering or bouncing.
NOTE: Heavy pressure will decrease the grinder’s speed and
put a strain on the motor. Normally the weight of the tool
alone is adequate for most grinding jobs. Use light pressure
when grinding jagged edges or loose bolts where there is the
potential for the grinder to snag on the metal edge.
Lift the grinder away from the workpiece before turning
off the grinder.

MAINTENANCE
WARNING:
When servicing use only identical RIDGID®
replacement parts. Use of any other parts may
create a hazard or cause product damage.
WARNING:
Always wear eye protection with side shields
marked to comply with ANSI Z87.1 along with
hearing protection and where necessary a full
face shield. Failure to do so could result in serious
personal injury. If operation is dusty, also wear a
dust mask.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline,
petroleum-based products, penetrating oils, etc.,
come in contact with plastic parts. Chemicals can
damage, weaken or destroy plastic which may
result in serious personal injury.
Electric tools used on fiberglass material, wallboard, spackling compounds, or plaster are subject to accelerated wear
and possible premature failure because the fiberglass chips
and grindings are highly abrasive to bearings, brushes,
commutators, etc. Consequently, we do not recommend
using this product for extended work on these types
of materials. However, if you do work with any of these
materials, it is extremely important to clean the product using compressed air.
LUBRICATION
All of the bearings in this product are lubricated with a sufficient amount of high grade lubricant for the life of the unit
under normal operating conditions. Therefore, no further
lubrication is required.
REPLACING THE WHEEL GUARD
After extended use, the wheel guard may wear and need
replacing. If you drop the grinder and damage the wheel
guard it may also be necessary for you to replace it. Refer
to Installing the Wheel Guard earlier in this manual.
BRUSH REPLACEMENT
See Figure 9, page 16.
This product has externally accessible brush assemblies
that should be periodically checked for wear.
Unplug the angle grinder.
With a flat head screwdriver, remove the brush caps. The
brush assembly is spring loaded and will pop out when
you remove the brush cap.
Remove the brush assembly (brush and spring). Check
for wear. Replace both brushes when either has less than
1/4 in. length of carbon remaining. Do not replace one
side without replacing the other.
Reassemble using new brush assemblies. Make sure
curvature of brush matches curvature of motor and that
brush moves freely in brush tube.
Replace brush cap and tighten securely. Do not over-
tighten.
