IMPORTANT SAFETY INSTRUCTIONS
WARNING! When using electric tools, machines or equipment, basic safety
precautions should always be followed to reduce the risk of re, electric shock,
and personal injury.
GENERAL SAFETY RULES
WARNING! READ AND UNDERSTAND ALL INSTRUCTIONS. Failure to follow
all instructions listed below may result in electrical shock,re, and/or serious
personal injury.
KEEP YOUR WORK AREA CLEAN AND WELL LIT. Cluttered benches and
dark areas invite injuries.
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 dust or fumes.
KEEP CHILDREN AND BYSTANDERS AWAY while operating a power tool.
Distractions can cause you to lose control. Protect others in the work area from
debris such as chips and sparks. Provide barriers and shields as needed.
ELECTRICAL SAFETY
4. DOUBLE INSULATED TOOLS are equipped with a polarized plug. One blade
is wider than the other, so it will t into a polarized outlet only one way. If it does
not t fully in the outlet, reverse the plug. If it still does not t, contact a qualied
electrician to install a polarized outlet. Do not change the plug in any way.
Double Insulation eliminates the need for a three wire grounded power cord
and grounded power supply system.
5. 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.
6. DO NOT EXPOSE POWER TOOLS TO RAIN OR WET CONDITIONS. Water
entering a power tool will increase the risk of electric shock.
7. DO NOT ABUSE THE CORD. Never use the cord to carry the tool or to pull the
plug from an outlet. Keep the cord away from heat, oil, sharp edges, or moving
parts. Replace damaged cords immediately. Damaged cords increase the risk
of electric shock.
8. WHEN OPERATING A POWER TOOL OUTSIDE, USE AN OUTDOOR-RATED
EXTENSION CORD RATED “W-A” or “W”. These cords are rated for outdoor
use and reduce the risk of electric shock.
PERSONAL SAFETY
9. STAY ALERT. Watch what you are doing & use common sense when operating
a power tool. Do not use tool while tired or under the inuence of drugs,
alcohol, or medication. A moment of inattention while operating power tools may
result in serious personal injury.
10. 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.
11. AVOID ACCIDENTAL STARTING. Be sure the switch is in the OFF position
before plugging in. Carrying tools with your nger on the switch or plugging in
tools with the switch on invites accidents.
12. 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.

IMPORTANT SAFETY INSTRUCTIONS
13. DO NOT OVERREACH. Keep proper footing and balance at all times. Proper
footing and balance enables better control of the tool in unexpected situations.
14. USE SAFETY EQUIPMENT. Always wear eye protection. Dust mask, non-skid
safety shoes, hard hat, or hearing protection must be used for appropriate
conditions.
TOOL USE AND CARE
15. USE CLAMPS OR OTHER PRACTICAL WAYS TO SECURE AND SUPPORT
THE WORK PIECE. Holding the work by hand or against your body is unstable
and may lead to loss of control.
16. DON’T FORCE THE TOOL. Use the correct tool for your application. The
correct tool will do the job better and more safely at the rate for which it was
designed.
17. DO NOT USE THE TOOL IF THE SWITCH DOES NOT TURN IT ON OR OFF.
Any tool that cannot be controlled with the switch is dangerous and must be
repaired.
18. DISCONNNECT THE PLUG FROM THE POWER SOURCE BEFORE
MAKING ANY ADJUSTMENTS, changing accessories, or storing the tool.
Such preventive measures reduce the risk of starting the tool accidentally
19. STORE IDLE TOOLS OUT OF REACH of children and other untrained
persons. Tools are dangerous in the hands of untrained users.
20. 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. Do not use a damaged tool. Tag damaged tools, “Do not use” until
repaired.
21. CHECK FOR MISALIGNMENT OR BINDING OF MOVING PARTS,
BREAKAGE OF PARTS, and any other conditions that may affect the tool’s
operation. If damaged, have the tool serviced before using. Many accidents are
caused by poorly maintained tools.
22. USE ONLY ACCESSORIES THAT ARE RECOMMENDED BY THE
MANUFACTURER for your model. Accessories that may be suitable for one
tool become hazardous when used on another tool.
SERVICE
23. TOOL SERVICE MUST BE PERFORMED BY QUALIFIED REPAIR
PERSONNEL at an authorized service centre. Service or maintenance
performed by unqualied personnel could result in a risk of injury.
24. 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.
SPECIFIC SAFETY RULES FOR YOUR ANGLE GRINDER
25. ALWAYS USE PROPER GUARD WITH THE GRINDING WHEEL. A guard
protects the operator from broken wheel fragments, should it shatter in use.
26. ACCESSORIES MUST BE RATED FOR AT LEAST THE SPEED
RECOMMENDED ON THE TOOL WARNING LABEL. Wheels and other
accessories running faster than their rated speed can y apart and cause injury.
27. HOLD TOOL BY INSULATED GRIPPING SURFACES when performing an
operation where a 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.

GUARD
Your grinder comes with an adjustable wheel guard (J, g.II). This is to allow you to
grind at various angles and still be protected to some extent from ying residue or
debris should a disc shatter in use.
If the guard needs to be installed, or if you wish to rotate the guard to provide
more protection at the angle you plan to use the grinder:
WARNING- Be sure the tool is switched off and unplugged.
Loosen the clamping screw (a, g.II) on the collar
Locate the guard collar onto the tool or rotate the guard to give you protection
and expose the disc on the appropriate side.
Tighten the screw to clamp the guard in place.
CAUTION- Do not use this tool with the guard removed.
SIDE HANDLE
The auxiliary side handle (I, g.III) for your grinder may be tted to either the left or
right side of the unit. Select the position which provides the most comfortable and
safe use.
WARNING- Be sure the tool is switched off and unplugged.

Screw the handle rmly into the threaded hole on the left side of the metal gear
head (b, g.III) for right-handed operation.
Screw the handle rmly into the threaded hole on the right side of the metal
gear head (c, g.III) for left-handed operation.
GRINDING AND CUT-OFF WHEELS
Your grinder is designed to accept only 115 mm or 4-1/2" diameter abrasive
discs with a 7/8" bore.
Check to ensure that any discs you use on this machine are rated for the 11,000-
rpm operating speed of your grinder.
Check also for any damage to an abrasive disc before you install it. Any disc
that shows a crack, has been dropped, or subjected to other damage due to
temperature extremes or solvents should be discarded. A damaged disc can y
apart in use and may cause serious injury to the operator or bystanders.
INSTALLING A GRINDING WHEEL OR CUTTING DISC
WARNING- Be sure the tool is unplugged.
Turn the tool upside down.
Place the inner ange (K, g.IV) over the spindle so that the two raised portions
tangental to the center hole (d, g.IV) mate with the ats on the shaft (e, g.IV).
The t should be tight and the inner ange should now turn with the shaft.
Fit the grinding or cutting disc on top of the inner ange, ensuring the bore ts
over the 7/8" raised boss on the inner ange.
Screw the disc retaining outer ange nut (f, g.V) down over the disc.
Depending on the disc thickness, the boss (g, g.V) on the outer ange nut can
face down or up. Normally, it should go down into the 7/8” bore on the abrasive
disc. Very thin cutting discs may require that the boss face away from the disc
so that the ange nut and the inner ange will securely clamp the disc between
them.
Fit the two prongs of the wrench (h, g.VI) into the holes in the outer ange nut
(f, g.V & VI).
Depress the spindle lock button (C, g.I) rmly and ensure the spindle does not
turn.
While the spindle lock button is depressed, tighten the ange nut, turning it
clockwise with the wrench.
Turn the wheel by hand, checking for any obstruction to its free movement.

OPERATION
ENGLISH
SWITCH
WARNING- Be sure the tool is switched off before plugging it in.
Plug in the tool.
When starting, hold the tool rmly with both hands, i.e. one hand on the housing
and the other gripping the side handle.
Check to make sure the abrasive disc is not obstructed.
Slide the switch on the left side of the machine forward, in the direction of the
marked I (ON) position, with your thumb (1, g.VII).
Switching the tool on or off under load will damage the switch.
To lock the switch in the I (ON) position, press the front off the switch button
down slightly (2, g.VII) when it has been slid all the way forward.
Allow the angle grinder to run at idle for at least a minute with the abrasive disc
correctly assembled but not in use. A disc that shows vibration at this stage
should be discarded immediately.
To stop the tool, release the on/off switch; or when the switch is engaged in
the lock-on position, press at the rear end of the switch button (g.VIII) to
make it spring back to the 0 (OFF) position.
WARNING-
Turn off your tool at once, unplug and inspect it for serious problems if:
Moving parts get stuck
Speed drops to an abnormally low level
The motor housing gets hot
Sparks or odours emit from the casing
OPERATING PROCEDURES
CAUTION- Do not cover the exhaust vents while the tool is in use. This may
cause damage to the motor and reduce the efciency of the tool.
Before starting the grinder, put on safety glasses and make sure that the
grinding wheel, guard and the tool are in good condition and correctly tted.
Always hold the tool rmly with one hand on the rear handle and the other on the
side handle.
Turn the angle grinder on and then apply the grinding wheel to the workpiece.
For the best results, hold the grinder at a 10 - 15 degree angle to the work piece.
Guide the abrasive disc’s contact point back and forth over the workpiece with a
steady motion.
Use just enough pressure to keep the grinder from chattering or bouncing.
Avoid overloading the tool for a long time, heavy pressure will decrease its
speed and put a strain on the motor.
Lift the grinder away from the workpiece before turning your grinder off.
When cutting, avoid tilting the tool out of the cutting plane. Ensure the cutting
disc has a clean edge.
Do not use a cutting disc for rough grinding.

MAINTENANCE
WARNING- It is recommended that all repairs or parts replacement be performed
only by a qualied service technician.
CARBON BRUSHES
The brushes and commutator of the tool should be examined after several
months of use. When the sparks around the commutator become excessive, the
carbon brushes should be changed.
CLEANING
WARNING- Before cleaning or performing any maintenance, the power supply
must be disconnected from the tool.
Dry, compressed air may be the most effective cleaning method.
CAUTION- Always wear safety goggles when cleaning tools with compressed air.
Ventilation openings must be kept clean. Do not attempt to clean by inserting
pointed objects through openings.
Regularly inspect all mountings and screws to ensure they are properly
tightened. Should any screws be loose, tighten them immediately. Failure to do
so may result in serious damage.
Keep the tool housing and handle clean and free of oil and grease using mild
soap and a damp (not wet) cloth.
Avoid overloading your grinder. It will become hot and lose efciency. Running it
free of load for a minute or two will allow it to cool itself to normal temperature.
Inspect the cord regularly and have it replaced by an authorized repair facility if it
is damaged.
Lubrication for this tool is done at the factory and should not be necessary again
under normal use.
Check the grinding disc regularly for cracking and other damage. Do not use a
damaged disc.
An authorized repair centre should do any repairs, modication, or maintenance
that involve disassembling the tool. Any damage to the tool should be corrected
at an authorized repair centre.
