GENERAL POWER TOOL SAFETY
WARNINGS
WARNING! Read all safety warnings and all
instructions. Failure to follow the warnings and
instructions 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 mains-operated (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
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.
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
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 earthed (grounded) power
tools. Unmodied 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 a residual current device (RCD)
protected supply. Use of an RCD reduces the risk
of electric shock.
3. PERSONAL SAFETY
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 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 off-position before connecting to
power source and/or battery pack, picking up or
carrying the tool. Carrying power tools with your
nger 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 or
jewellery. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewellery
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
these devices 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.
6
2200W ANGLE GRINDER EN
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
a) Have your power tool serviced by a qualied
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
SAFETY INSTRUCTIONS FOR ALL
OPERATIONS
Safety Warnings Common for Grinding, Sanding,
Polishing or Abrasive Cutting-Off Operations:
a) This power tool is intended to function as a
grinder, sander, wire brush, polisher or cut-
off tool. Read all safety warnings, instructions,
illustrations and specications provided with this
power tool.
b) Operations such as wire brushing, 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
specically 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
7
2200W ANGLE GRINDER EN
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) 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 ammable
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.
q) Recommendation that the tool always be
supplied via a residual current device with a
rated residual current of 30 mA or less.
FURTHER SAFETY INSTRUCTIONS
FOR ALL OPERATIONS
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 rm 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 specic 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, accidental
contact with wheel and sparks that could ignite
clothing.
d) 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.
e) Always use undamaged wheel anges that
8
2200W ANGLE GRINDER EN
are of correct size and shape for your selected
wheel. Proper wheel anges support the wheel
thus reducing the possibility of wheel breakage.
Flanges for cut-off wheels may be different from
grinding wheel anges.
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.
ADDITIONAL SAFETY WARNINGS
SPECIFIC FOR ABRASIVE CUTTING-
OFF OPERATIONS
a) Do not “jam” the cut-off wheel or apply excessive
pressure. Do not attempt to make an excessive
depth of cut. Overstressing the wheel increases
the loading and susceptibility to twisting or
binding of the wheel in the cut and the possibility
of kickback or wheel breakage.
b) Do not position your body in line with and behind
the rotating wheel. When the wheel, at the point
of operation, is moving away from your body, the
possible kickback may propel the spinning wheel
and the power tool directly at you.
c) When wheel is binding or when interrupting
a cut for any reason, switch off the power tool
and hold the power tool motionless until the
wheel comes to a complete stop. Never attempt
to remove the cut-off wheel from the cut while the
wheel is in motion otherwise kickback may occur.
Investigate and take corrective action to eliminate
the cause of wheel binding.
d) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully reenter the cut. The wheel may bind,
walk up or kickback if the power tool is restarted in
the workpiece.
e) Support panels or any oversized workpiece
to minimize the risk of wheel pinching and
kickback. Large workpieces tend to sag under
their own weight. Supports must be placed under
the workpiece near the line of cut and near the
edge of the workpiece on both sides of the wheel.
f) Use extra caution when making a “pocket
cut” into existing walls or other blind areas.
The protruding wheel may cut gas or water
pipes, electrical wiring or objects that can cause
kickback.
SAFETY WARNINGS SPECIFIC 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 SPECIFIC 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.

mounted.
Loosen the Clamp Adjusting Nut (15).
Place the wheel guard (8) with coded projection into
the coded groove on the spindle of the machine head
and rotate to the required position (working position).
The closed side of the wheel guard (8) must always
point to the operator.
Then tighten the Clamp Adjusting lever (A2).
Wheel Guard for Cutting
WARNING! For cutting metal, always work with
the wheel guard for cutting.
The wheel guard for cutting (13) is mounted in the
same manner as the wheel guard for grinding.
Open the clamping lever. Place the wheel guard (8)
with coded projection into the coded groove on the
spindle of the machine head and rotate to the required
position (working position).
To fasten the wheel guard (8), close the clamping
lever.
The closed side of the wheel guard must always point
to the operator.
NOTE: with the clamping lever open the clamp
adjusting nut can be adjusted to ensure the guard is
securely clamped after the clamping lever is nally
closed.
2. INSTALLING AND ADJUSTING AUXILIARY HANDLE (See
Fig. B)
An auxiliary handle is supplied and can be xed into
any of the three positions on the gear housing. If you
are right handed t the handle as shown in Fig B. If
you are left handed t the handle the other way round.
When using a cutting disc, you can screw the handle
into the position on top of the gearcase.
NOTE: This handle should be used at all times to
maintain complete control of the tool.
3. FITTING THE DISCS (See Fig. C1, C2, C3)
Put the inner ange onto the tool spindle. Ensure it is
located on the two ats of spindle (See Fig C1).
Place the disc on the tool spindle and inner ange.
Ensure it is correctly located. Fit the threaded outer
ange making sure it is facing in the correct direction
for the type of disc tted. For grinding discs, the
ange is tted with the raised portion facing towards
the disc. For cutting discs, the ange is tted with the
ABN: Australian Business Number. By this number,
business information such as entity type, status,
business location etc. can be found at website

Press in the spindle lock button (1) and rotate the
spindle by hand until it is locked. Keeping the lock
button pressed in, tighten the outer ange with the
spanner provided (See Fig C3).
NOTE: After mounting the grinder tool and before
switch on, check that the grinding tool is correctly
mounted and that it can be turn freely, make sure that
the grinding tool does not graze against the protecting
guard or other parts.
4. SPINDLE LOCK BUTTON
Clean the grinder spindle and all parts to be mounted.
For clamping and loosening the grinding tools, lock
the grinder spindle with the spindle lock button.
WARNING! Actuate the spindle lock button only
when the grinder spindle is at a standstill!
5. USING THE TURNABLE HANDLE (See Fig. D)
To best suit the different working positions, your angle
grinder is equipped with a turnable handle.
Press the rear of the locking button (2) on the turnable
handle and you can rotate the handle 900 to left or
right. Then release the locking button. A click will be
heard, when the handle is then fully locked in place.
WARNING! Make sure the handle in the locked
position before start the angle grinder.
Rotating the handle is permitted only when the grinder
spindle is at a standstill!.
6. HAND GRIP AREAS (See Fig. E)
Always hold your angle grinder rmly with both hands
when operating.
7. SAFETY LOCK-OFF SWITCH (See Fig. F)
Your switch is locked off to prevent accidental
starting. With your hand on the on/off switch (a) use
your nger to push lever (b) forward and then depress
on/off switch (a). Then release lever (b). Your tool is
now on. To switch off just release on/off switch.
8. SOFT START
Internal electronic components allow the motor speed
to increase slowly, which reduces the “twisting” effect
on your wrists due to the high power motor.
WARNING! Make sure the speed in top before
start grinding or cutting
9. TO USE THE GRINDER (SEE FIGS E & G)
ATTENTION: Do not switch the grinder on whilst
the disc is in contact with the work piece. Allow the
disc to reach full speed before starting to grind.
Hold your angle grinder with one hand on the main
handle and other hand rmly around the auxiliary
handle.
Always position the guard so that as much of the
exposed disc as possible is pointing away from you.
Be prepared for a stream of sparks when the disc
touches the metal.
For best tool control, material removal and minimum
overloading, maintain an angle between the disc and
work surface of approximately 15o- 30owhen grinding.
Use caution when working into corners as contact
with the intersecting surface may cause the grinder to
jump or twist.
When grinding is complete allow the work piece to
cool. Do not touch the hot surface.
10. CUTTING
WARNING! For cutting metal, always work with
the wheel guard for cutting
When cutting, do not press, tilt or oscillate the
machine. Work with moderate feed, adapted to the
material being cut.
Do not reduce the speed of running down cutting
discs by applying sideward pressure.
The direction in which the cutting is performed is
important.
The machine must always work in an up-grinding
motion. Therefore, never move the machine in the
other direction! Otherwise, the danger exists of it
being pushed uncontrolled out of the cut.
11. OVERLOAD
Overloading will cause damage to the motor of your
angle grinder. This can happen if your angle grinder is
subjected to heavy use for prolonged periods of time.
Do not in any circumstances, attempt to exert too much
pressure on your angle grinder to speed up your work.
If your angle grinder becomes too hot, run you angle
grinder under no load for 2-3 minutes until it has
cooled to normal operation temperature.
12. TO REPLACE THE BRUSHES (See Fig. H)
Remove the screw securing the motor brush cover
(See Fig. H). Remove the cover, gently lift out, and pull
the spade connector free. Hold back the coil spring
and slide the worn brush out of the housing, carefully
release the spring. Locate the replacement brush, (in
the same orientation) whilst again holding back the
11
2200W ANGLE GRINDER EN
coil spring. Ensure the brush is located and free to
move, release the spring; it should now sit within the
groove on the brush. Re-attach the spade connector to
the terminal, replace the cover and secure.
NOTE: Brushes should be replaced in pairs. If any
query, contact the Helpline.
WORKING HINTS FOR YOUR
GRINDER
1. Always start at no load to achieve maximum speed
then start working.
2. Do not force the disc to work faster, reducing the
Disc’s moving speed means longer working time.
3. Always work with a 15°-30° angle between disc
and workpiece. Larger angles will cut ridges into
the workpiece and affect the surface nish. Move
the angle grinder across and back and forth over
the workpiece.
4. 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
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.
5. When cutting very hard material best results can
be achieved with a diamond disc.
6. When using a diamond disc it will become very
hot. If this happens 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.
7. Always ensure the workpiece is rmly held or
clamped to prevent movement.
MAINTENANCE
Remove the plug from the socket before carrying
out any adjustment, servicing 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. Occasionally you may see sparks through the
ventilation slots. This is normal and will not damage
your power tool.
If the supply cord is damaged, it must be replaced
by the manufacturer, its service agent or similarly
qualied persons in order to avoid a hazard.
TROUBLESHOOTING
Although your new angle grinder is really very simple
to operate, if you do experience problems, please
check the following:
1. If your grinder will not operate check the power at
the main plug.
2. If your grinder wheel wobbles or vibrates, check
that outer ange is tight, check that the wheel is
correctly located on the ange plate.
3. If there is any evidence that the wheel is
damaged do not use as the damaged wheel may
disintegrate, remove it and replace with a new
wheel. Dispose of old wheels sensibly.
4. If working on aluminum or a similar soft alloy, the
wheel will soon become clogged and will not grind
effectively.
