4. GRINDING
1. Place the workpiece onto the tool
rest.
2. Slowly guide the workpiece towards
the grinding wheel, ensuring that the
workpiece is at the desired angle
when it makes contact.
NOTE: Exert only light pressure on
the workpiece so that it can be ground
at constant speed. Instead of forcing
your work, high pressure will cause the
drive unit to slow down, even stop and
overloading the motor.
3. Move the workpiece from side to side
to produce an optimal grinding result.
This way the grinding wheel will be
evenly worn. Allow the workpiece to
cool down occasionally.
IMPORTANT! IF THE GRINDING WHEEL BECOMES JAMMED
DURING OPERATION, REMOVE THE WORKPIECE AND WAIT
UNTIL THE TOOL REACHES ITS TOP SPEED AGAIN.
IMPORTANT! FOR YOUR OWN SAFETY, IT IS ESSENTIAL
TO SECURE SMALL WORKPIECES WITH A CLAMP OR
VISE.
5. POLISHING
1. Apply a thin coating of polishing
paste (supplied) to the surface of
the Polishing wheel.
2. Press the workpiece onto the wheel
and move it back and forth across
the surface of the wheel.
3. Always carry out polishing work in the
direction of rotation of the polishing
wheel.
IMPORTANT! POLISHING IN THE OPPOSITE DIRECTION TO
THE DIRECTION OF ROTATION OF THE GRINDING WHEELS
CAN CAUSE DAMAGE TO THE WHEEL, WHICH IN TURN
CAN RESULT IN INJURIES.

6. MAINTENANCE
Changing the Wheels
1. Remove the 3 screws that
hold the side section of the
safety hood and remove the
wheel guard cover.
2. With a spanner, hold the
wheel nut on the opposite
side in position, while
loosening the wheel nut of
the wheel you wish to change
with another spanner.
NOTE: The grinding wheel on the left is fastened with a left handed
thread and the wheel on the right with a right-handed thread.
3. Remove the ange and
replace the grinding wheel.
4. To assemble, proceed in
the reverse order.
5. Manually spin the newly
mounted wheel to check
that it rotates freely prior
to operation.
Carbon brushes
Carbon brushes will wear out after
many uses, causing the Bench
Grinder to spark and/or stop.
The brushes are a wearing component
of the Bench Grinder and should be
replaced prior to the carbon wearing
out completely.
Take the Bench Grinder to a suitably
qualied electrician or power tool repairer for replacement.
Always replace both brushes at the same time.
NOTE: Ozito Industries will not be responsible for any damage or
injuries caused by the repair of the Bench Grinder by an unauthorised
person or by mishandling of the Bench Grinder.
Replacing the power cable
If the power cable for this equipment is damaged, it must be replaced
by the manufacturer or its after-sales service or similarly trained
personnel to avoid danger.
Cleaning
• Keep all safety devices, air vents and the motor housing free of
dirt and dust as far as possible. Wipe the equipment with a clean
cloth or blow it with compressed air at low pressure.
• We recommend that you clean the device immediately each time
you have nished using it.
• Clean the equipment regularly with a moist cloth and some soft
soap. Do not use cleaning agents or solvents; these could attack
the plastic parts of the equipment. Ensure that no water can seep
into the device. The ingress of water into an electric tool increases
the risk of an electric shock.
Storage
Store the equipment and accessories out of children’s reach in a
dark and dry place at above freezing temperature. The ideal storage
temperature is between 5 and 30 °C. Store the electric tool in its
original packaging.

BENCH GRINDER SAFETY WARNINGS
WARNING! When using mains-powered tools, basic safety precautions, including the
following, should always be followed to reduce risk of re, electric shock, personal injury
and material damage.
Read the whole manual carefully and make sure you know how to switch the tool off in an emergency, before
operating the tool.
Save these instructions and other documents supplied with this tool for future reference.
The electric motor has been designed for 230V and 240V only. Always check that the power supply
corresponds to the voltage on the rating plate.
Note: The supply of 230V and 240V on Ozito tools are interchangeable for Australia and
New Zealand.
This tool is double insulated therefore no earth wire is required.
If the supply cord is damaged, it must be replaced by an electrician or a power tool repairer in order to avoid
a hazard.
Note: Double insulation does not take the place of normal safety precautions when operating this tool. The
insulation system is for added protection against injury resulting from a possible electrical insulation failure
within the tool.
Using an Extension Lead
Always use an approved extension lead suitable for the power input of this tool. Before use, inspect the
extension lead for signs of damage, wear and ageing. Replace the extension lead if damaged or defective.
When using an extension lead on a reel, always unwind the lead completely. Use of an extension lead not
suitable for the power input of the tool or which is damaged or defective may result in a risk of re and electric
shock.
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.
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. Unmodied 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 inuence 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 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 qualied repair person using only identical
replacement parts. This will ensure that the safety of the power tool is maintained.
b. If the supply cord is damaged, it must be replaced by the manufacturer,
its service agent or similarly qualied persons in order to avoid a hazard.
