EXTENSION CORDS
WARNING: Use proper extension cords. Make
sure your extension cord is in good condition and is
a 2-wire extension cord which matching receptacle
which will accept the machine’s plug. When using an
extension cord, be sure to use one heavy enough to
carry the current of the machine. An undersized cord
will cause a drop in line voltage, resulting in loss
of power and overheating. If in doubt, use the next
heavier gauge. The smaller the gauge number, the
heavier the cord.

SAVE THESE INSTRUCTIONS
1. WORK AREA
- KEEP YOUR WORK AREA CLEAN AND WELL LIT. Clut-
tered benches and dark areas invite accidents.
- DO NOT OPERATE POWER TOOLS IN EXPLOSIVE ATMO-
SPHERES, SUCH AS IN THE PRESENCE OF FLAMMABLE
LIQUIDS, GASES OR DUSTS. Power tools create sparks
which may ignite the dust or fumes.
- KEEP BY-STANDERS, CHILDREN, AND VISITORS AWAY
WHILE OPERATING A POWER TOOL. Distractions can
cause you to lose control.
2. 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 eliminates the need for the
three wire grounded power cord and grounded
power supply system. Before plugging in the tool,
be certain the outlet voltage supplied is within the
voltage marked on the nameplate. Do not use “AC
only” rated tools with a DC power supply.
- AVOID BODY CONTACT WITH GROUNDED SURFACES
SUCH AS PIPES, RADIATORS, RANGES AND REFRIGERA-
TORS. There is an increased risk of electric shock
if your body is grounded. If operating the power
tool in damp locations is unavoidable, a Ground
Fault Circuit Interrupter must be used to supply the
power to your tool. Electrician’s rubber gloves and
footwear will further enhance your personal safety.
- DON’T EXPOSE POWER TOOLS TO RAIN OR WET CONDI-
TIONS. 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 mov-
ing 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. Refer to the “Recom-
mended sizes of Extension Cords” in the Accessory
section of this manual.
- GROUNDED TOOLS MUST BE PLUGGED INTO AN OUTLET
PROPERLY INSTALLED AND GROUNDED IN ACCORDANCE
WITH ALL CODES AND ORDINANCES. NEVER REMOVE
THE GROUNDING PRONG OR MODIFY THE PLUG IN ANY
WAY. Do not use any adapter plugs. Check with
a qualified electrician if you are in doubt as to
whether the outlet is properly grounded. If the tool
should electrically malfunction or break down,
grounding provides a low resistance path to carry
electricity away from the user.
3. 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 inat-
tention 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.
Keep handles dry, clean and free from oil and
grease. Rubber gloves and non-skid footwear are
recommended when working outdoors.
- 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. Do not use a tool
if the power switch does not turn it “ON” and “OFF”.
- REMOVE ALL ADJUSTING KEYS AND WRENCHES. Make
a habit of checking that adjusting keys, wrenches,
etc. are removed from the tool before turning it
“ON”.
- DO NOT OVERREACH. KEEP PROPER FOOTING AND
BALANCE AT ALL TIMES. Proper footing and balance
enable better control of the tool in unexpected
situations.
- USE SAFETY EQUIPMENT. ALWAYS WEAR EYE PROTEC-
TION. Dust mask, non-skid safety shoes, hard hat,
or hearing protection may be used for appropriate
conditions.
- KEEP HANDS AWAY FROM ALL CUTTING EDGES AND
MOVING PARTS.
- IF DEVICES ARE PROVIDED FOR THE CONNECTION OF
DUST EXTRACTION AND COLLECTION FACILITIES, EN-
SURE THESE ARE CONNECTED AND PROPERLY USED. Use
of these devices can reduce dust-related hazards.
4. TOOL USE AND CARE
- USE CLAMPS OR OTHER PRACTICAL WAYS TO
SECURE AND SUPPORT THE WORK-PIECE TO A STABLE
M-RK4747K 2006.6.2.indd 6 2006-7-5 10:54:26

7
ANGLE GRINDER ENG
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.
Excessive force only causes operator fatigue,
increased wear and reduced control.
- DO NOT USE TOOL IF SWITCH DOES NOT TURN IT “ON”
OR “OFF”. A tool that cannot be controlled with the
switch is dangerous and must be repaired.
- DISCONNECT THE TOOL FROM THE POWER SOURCE
BEFORE MAKING ANY ADJUSTMENTS, CHANGING AC-
CESSORIES, OR STORING THE TOOL. Such preventative
safety measures reduce the risk of starting the tool
accidentally.
- STORE IDLE TOOLS OUT OF 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
easier to control.
- CHECK FOR MISALIGNMENT OR BINDING OF MOVING
PARTS, BREAKAGE OF PARTS, AND ANY OTHER CONDI-
TION THAT MAY AFFECT THE TOOL’S OPERATION. If dam-
aged, 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 create a risk
of injury when used on another tool.
- USE THE RIGHT TOOL. Do not force the tool or attach-
ment to do a job for which it was not designed.
5. SERVICE
- TOOL SERVICE MUST BE PERFORMED ONLY BY QUALI-
FIED REPAIR PERSONNEL. Service or maintenance
performed by unqualified personnel could result in
a risk of injury.
- 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 electric shock or
injury.

OPERATING INSTRUCTIONS
NOTE: Before using the tool, read the
instruction book carefully.
1. ON/OFF SWITCH
Slide the switch forward to start your tool and lock
your tool for continuous working. To switch off your
tool, depress the rear of the switch (See A).
2. HAND GRIP AREAS
Always hold your angle grinder firmly with both
hands when operating (See B).
3. ADJUSTABLE FRONT HANDLE
You have the option of two working positions to
provide the safest and most comfortable control of
your angle grinder (See C). The handle is screwed
clockwise into either hole on the sides of the gear
case.
4. SPINDLE LOCK BUTTON
Must only be used when changing a disc. Never press
when the disc is rotating!
5. DISC FITTING
The inner flange (6) is located over the spindle (7)
and on the spindle flat. Locate the disc onto the
inner flange and then the outer flange (5) is screwed
onto the spindle (See E). Press the spindle lock
button (4) and rotate the spindle until it locks, then
firmly tighten the outer flange using your special
spanner to clamp the disc (See D). The pins on your
special spanner locate in the holes on the outer
flange. Check the disc rotates freely and is securely
clamped. Make a no load test run for 30 seconds to
check disc vibration and disc run out. To remove a
disc, reverse these instructions.
6. ADJUSTABLE OUTER FLANGE CLAMPING
The outer flange (5) should be adjusted to suit
different disc thickness. For thinner cutting or
diamond discs the raised part of the outer flange is
fitted facing away from the disc (See F.1). For thicker
grinding discs the raised part of the outer flange is
fitted facing the disc to provide improved support
for the disc hole (See F.2). Always ensure your disc is
securely clamped.
7. GUARD ADJUSTMENT
To move the guard you must release the guard lock
bolt (8) using the other end of the special spanner
(See G). The guard can then be rotated to provide
maximum protection against sparks and debris.
Finally, tighten the guard bolt (8).
8. REMOVING THE GUARD
Only to be removed for use with sanding, flap disc
and wire cup brush accessories only. Never remove
your guard for any other working conditions. Remove
the disc, both flanges, guard bolt, screws (9) x 3 and
guard. Keep all parts in a safe place.
9. FITTING SANDING ACCESSORIES OR WIRE CUP BRUSH
Check the accessory specification for rated speed,
spindle thread and other dimensions are correct for
your angle grinder. Follow the fitting instructions
with your new accessory.
WORKING HINTS FOR YOUR ANGLE
GRINDER
a. If your power tool becomes too hot, run no load for
2-3 minutes to cool the motor.
b. Never start your angle grinder with the disc/ac-
cessory in contact with the workpiece.
c. Always start at no load to achieve maximum speed
then start working.
d. Do not force the disc to work faster, reducing the
Disc’s moving speed means longer working time.
e. Always work with a 10-20 angle between disc and
workpiece when grinding. Larger angles will cut
ridges into the workpiece and affect the surface
finish. Move the angle grinder across and back and
forth over the workpiece.
f. When using a cutting disc never change the
cutting angle otherwise you will stall the disc
and angle grinder motor or break the disc. When
M-RK4747K 2006.6.2.indd 9 2006-7-5 10:54:29

ANGLE GRINDER ENG
cutting, only cut in the opposite direction to the
disc rotation. If you cut in the same direction as
the disc rotation the disc may push itself out of the
cut slot.
g. When cutting very hard material best results can
be achieved with a diamond disc. When using a
diamond disc it will become very hot. If this hap-
pens you will see a full ring of sparks around the
rotating disc. Stop cutting and allow to cool at no
load speed for 2-3 minutes.
h. Always ensure the workpiece is firmly held or
clamped to prevent movement.
MAINTAIN TOOLS WITH CARE
Keep tools sharp and clean for better and safer
performance. Follow instructions for lubricating and
changing accessories. Inspect tool cords periodi-
cally and if damaged, have repaired by authorized
service facility.
Your power tool requires no additional lubrication or
maintenance. There are no user serviceable parts
in your power tool. Never use water or chemical
cleaners to clean your power tool. Wipe clean with a
dry cloth. Always store your power tool in a dry place.
Keep the motor ventilation slots clean. Keep all
working controls free of dust. If you see some sparks
flashing in the ventilation slots, this is normal and
will not damage your power tool.
