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 all of 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 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 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 influence 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 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 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 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
a) Have your power tool serviced by a qualified repair person using only
identical replacement parts. This will ensure that the safety of the power tool is

ADDITIONAL SAFETY INSTRUCTIONS FOR ANGLE GRINDERS
a) This power tool is intended to function as a grinder, polisher or cut-off
tool. 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 or 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 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 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 shock the operator.
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 flammable materials. Sparks could ignite
these materials.
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.

Additional safety instructions for grinding and cutting-off operations
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 operator from broken wheel fragments and
accidental contact with wheel.
NOTE: The above warning may be omitted for die grinders and grinders or cut-off
grinders with rated capacity of less than 55mm.
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.
Additional safety instructions for 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.

BE SURE TO DISCONNECT THE ANGLE GRINDER FROM THE POWER SUPPLY
BEFORE ATTACHING OR REMOVING A DISC OR ATTACHMENT.
Make sure the grinding or cutting disc is mounted with the label on top or
facing the angle grinder. If you are fitting any other kind of attachment, refer to
attachment fitting instructions. Ozito Industries P/L will not be responsible for
any damage or injury caused due to the incorrect fitting of grinding or cutting
discs or any other kind of attachment. Incorrect attachments can
cause the motor to burn out, generally damage the tool and/or cause injury.
Assembling the Side Handle
The side handle should be assembled to the grinder prior to use. This is done by
screwing the threaded end of the handle firmly in to the metal gear case of the
grinder. There are three different positions that the handle can be fitted to the grinder.
Choose the most appropriate position considering user comfort (preferred hand) and
the task at hand. Rubber plugs can seal the unused holes in the metal gear case. Two
have been supplied on the unit.
Adjusting the Safety Guard
Ensure the guard is fitted and at an angle which ensures it is between you and the
disc/wheel. The guard is there to protect you from dislodging objects at the work
piece and from accidental contact with the disc/wheel, of your hand, fingers or other
parts of your body.
To adjust the guard, loosen the guard securing screw using the allen key supplied in
the kit box. Rotate the guard into the required position, then refasten the screw.
Ensure the guard is firmly secured prior to use.
Attaching and Removing Grinding Discs
• Inspect the grinding disc before fitting and during use to ensure it is not deformed
or cracked.
Note: Always ensure replacement discs/wheels maximum no load “RPM” speed
exceeds the no load speed marked on the rating label of this grinder. Use of a disc or
wheel which maximum no load “RPM” speed is less than the grinders is a hazard.
•Remove the outer flange (threaded flange) by hand if loose. If tight, depress the
spindle lock button at the top of the metal gear case and rotate the spindle to
locate the lock position. With the spindle locked and the spindle lock button still
depressed, use the pin spanner supplied to loosen (anti-clockwise) the outer flange.
•Holding the angle grinder with the spindle facing upwards, ensure the inner flange
(non-threaded flange) is on the spindle and located correctly. The two machined
flat sections on one side of the inner flange must face the angle grinder and locate
in the appropriate position on the spindle.
• Insert the grinding disc onto the angle grinder spindle with the disc label facing
the angle grinder. The hole in the disc should be located onto the spindle. Ensure
that the hole in the disc locates and fits firmly into the ring section of the inner flange.
•Screw the outer flange onto the spindle with the raised ring section facing the
angle grinder. This ring section must locate within the hole in the disc.
OPERATION

OPERATION (cont.)
• Tighten the outer flange by locking the spindle, as explained previously, then
use the pin spanner to tighten the flange.
• Removal of the disc is conducted in reverse order to the above.
Note: 80mm flanges should be used for cutting discs as they offer more support
for the disc. When fitting the outer flange (threaded flange) over a cutting disc, the
raised ring section should face away from the grinder in order for the face of the
outer flange to sit flush against the bottom side of the cutting disc. 40mm flanges
should be used for grinding discs but the 80mm flanges can also be used if they
do not interfere with the work piece you are grinding. If they come into contact
with the work piece while the disc is spinning, it may be wiser to use the 40mm
flanges as such contact may cause damage to the flanges and cause difficulty
when trying to change discs.
• Regularly check that the disc outer flange has not loosened during use.
Note: When fitting a cutting disc, the raised ring section on the outer flange
should face away from the disc.
Paper Washers
10 paper washers have been included in this kit. These are for using with cutting
discs. When using cutting discs with angle grinders, it is not uncommon for the
outer flange to self tighten during use.
By placing the washer over the spindle between the top of the cutting disc and
the inner flange, this ensures the outer flange can easily be removed as described
in Attaching and Removing Grinding Discs.
Replacement paper washers can be supplied by your local hardware store. They
usually come packed within the boxes that cutting discs are supplied in.
Grinding and Cutting Discs
• Do not fit or use a grinding disc for cutting applications - For cutting, use a
cutting disc and ask your hardware retailer for advice regarding the type of
material you wish to cut. Grinding discs are used for grinding metal only.
• The grinding disc is not solid. It is made from grit which is bonded together
with reinforcement and adhesives. It is always possible that a part of the disc
can dislodge and fly away from the tool at high speed. This is why you must
wear the appropriate safety equipment (glasses, gloves and protective
clothing).
• Do not use any kind of attachment (discs or otherwise) which have a diameter
greater than 230mm (9”).
