SETUP & PREPARATION
ASSEMBLY
The Bench Grinder is a combination tool for the grinding and polishing of
metals, plastics, and other materials.
- IMPORTANT! THE EQUIPMENT AND PACKAGING MATERIAL ARE NOT TOYS. DO NOT LET CHILDREN PLAY WITH PLASTIC BAGS, FOILS OR SMALL PARTS. THERE IS A DANGER OF SWALLOWING OR SUFFOCATING!
- IMPORTANT! BEFORE ASSEMBLING YOUR BENCH GRINDER, MAKE SURE THAT THE MOTOR IS OFF AND THE TOOL DISCONNECTED FROM THE POWER SUPPLY TO PREVENT ACCIDENTAL STARTING.
Securing the Grinder
Before operating the Bench Grinder, it should be firmly secured to a workbench
or a stable base. Insert screws through the two mounting holes at either side
of the base and use a screwdriver to fix the grinder to the surface.
Fitting the Safety Shield Brackets
NOTE: All covers and safety devices must be properly fitted correctly before the equipment is switched on.
- Safety shields must be fitted to each wheel guard cover of the Bench Grinder before operation.
- Attach safety shields to the wheel guard cover by inserting two adjusting screws through the slots in the safety shield bracket and the corresponding holes in the safety hood.
- Position the safety shield bracket so that the distance between the grinding wheel and the safety shield bracket is as small as possible and does not exceed 2 mm.
- Hold the nut at the rear of the safety shield bracket in place with a spanner, while tightening the front adjusting screws with a screwdriver.
NOTE: Adjust the safety shield bracket periodically to compensate for wear on the grinding wheel.
Fitting the Safety Eye Shields
- Position the safety eye shields between the vertical braces at the top of the safety shield brackets.
- Insert a long screw through a washer, then through the safety shield bracket and safety eye shield (screws and washers supplied).
- Place a washer on the end of the screw and fasten the assembly in place with a nut.
- Hold the nut in place with a spanner, while tightening the screw with a screwdriver. Do not over tighten.
Fitting the Adjustable Tool Rest
The Bench Grinder comes with two adjustable tool rests that aid the user in
holding items steady as they are being applied to the grinding wheels.
- Align the slot in the tool rest with the hole in the bottom of the wheel guard cover.
- Place the washers on the threaded end of the star screw.
- Secure the adjustable tool rest to the grinder using the starscrew. Do not fully tighten until the final adjustments have been made.
- Adjust the tool rest so that the distance between the grinding wheel and the tool rest is as small as possible and does not exceed 2 mm. Tighten the star screw.
THE FLEXIBLE SHAFT
Installing the Flexible Drive
NOTE: Fitting the accessory flexible drive shaft is optional and should
only be fitted when required.
The flexible drive is designed for the grinding, deburring, polishing,
engraving, cutting, milling, and cleaning of wood, metal, and plastic in model
making, in workshops, and in the home. Use the tool and its accessories only
for the applications described.
- Insert the internal shaft of the flexible drive into the guide shaft on the right-hand side of the grinder.
- Secure the fastening nut of the flexible drive to the equipment thread by hand (left-hand thread).
NOTE: Adjust the tool rest periodically to compensate for wear on the grinding wheel.
IMPORTANT! WHEN YOU WORK WITH THE FLEXIBLE DRIVE, THE SAFETY SHIELD MUST BE PLACED RIGHT UP AGAINST THE ADJUSTABLE TOOL REST TO PREVENT ACCIDENTAL TOUCHING OF THE WHEELS.
Inserting the accessories into the Flexible Drive
- Press the supplied locking pin into the hole in the flexible drive and turn the shaft until the pin latches in place.
- Undo the collet chuck nut with the supplied spanner.
- Insert the required accessory into the sleeve and tighten the collet chuck nut.
IMPORTANT! ALWAYS DETACH THE FLEXIBLE DRIVE FROM THE GRINDER WHEN NOT IN USE. AN ATTACHED FLEXIBLE DRIVE MAY WHIP ABOUT UNCONTROLLABLY IF IT IS NOT BEING HELD.
OPERATION
CAUTION: TO REDUCE THE RISK OF ELECTRICAL SHOCK, A RESIDUAL CURRENT DEVICE (RATED 30mA OR LESS) SHOULD BE USED.
On/Off Switch
- To switch ON the equipment set the On/Off switch to the “I” position.
- After switching ON, wait for the equipment to reach its maximum speed of rotation. Only then should you begin with the grinding.
- Move the On/Off switch to the “O” position to switch OFF the equipment.
Variable Speed Dial
The required speed can be set with the variable speed dial.
Speed of the flexible Drive
The correct speed depends on the tool used and the type of material being
processed.
- Small cutters/grinding stones: High speed (not included).
- Large cutters/grinding stones: Low speed (not included)
Using the flexible Drive
- Precision work/ engraving: hold the drive unit like a pen.
- Rough work: hold the drive unit like the handle of a hammer.
GRINDING
-
Place the workpiece onto the tool rest.
-
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 a constant speed. Instead of forcing your work, high pressure will cause the drive unit to slow down, even stopping and overloading the motor. -
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 SAFETY, IT IS ESSENTIAL TO SECURE SMALL WORKPIECES
WITH A CLAMP OR VISE.
POLISHING
- Apply a thin coating of polishing paste (supplied) to the surface of the Polishing wheel.
- Press the workpiece onto the wheel and move it back and forth across the surface of the wheel.
- 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.
MAINTENANCE
IMPORTANT! BEFORE CLEANING YOUR BENCH GRINDER OR CARRYING OUT ANY
MAINTENANCE PROCEDURE, MAKE SURE THAT THE MOTOR IS OFF AND THE TOOL
DISCONNECTED FROM THE POWER SUPPLY TO
PREVENT ACCIDENTAL STARTING.
Changing the Wheels
-
Remove the 3 screws that hold the side section of the safety hood and remove the wheel guard cover.
-
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. -
Remove the flange and replace the grinding wheel.
-
To assemble, proceed in the reverse order.
-
Manually spin the newly mounted wheel to check that it rotates freely before 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 before the carbon wears out completely. Take the Bench
Grinder to a suitably qualified 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 unauthorized 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 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 finished 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.

ELECTRICAL SAFETY
WARNING! When using mains-powered tools, basic safety precautions, including the following, should always be followed to reduce the risk of fire, 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 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
aging. 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

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, fire, 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.
Work area safety
- Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.
- Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks that may ignite the dust or fumes.
- Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
Electrical safety
- 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 the risk of electric shock.
- 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.
- Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
- Do not abuse the cord. Never use the cord for carrying, pulling, or unplugging the power tool. Keep the cord away from heat, oil, sharp edges, or moving parts. Damaged or entangled cords increase the risk of electric shock.
- When operating a power tool outdoors, use an extension cord suitable for outdoor use. The use of a cord suitable for outdoor use reduces the risk of electric shock.
- If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. The use of an RCD reduces the risk of electric shock.
Personal safety
- 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.
- Use personal protective equipment. Always wear eye protection. Protective equipment such as dust masks, non-skid safety shoes, hard hats, or hearing protection used for appropriate conditions will reduce personal injuries.
- Prevent unintentional starting. Ensure the switch is in the off-position before connecting
- to a power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
- 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.
- Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
- Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.
- If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. The use of dust collection can reduce dust-related hazards.
Power tool use and care
- 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.
- Do not use the power tool if the switch does not turn on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
- 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.
- 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.
- 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.
- Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
- Use the power tool, accessories tool bits, etc. to 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.
Service
- 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 maintained.
- If the supply cord is damaged, it must be replaced by the manufacturer, its service agent, or similarly qualified persons to avoid a hazard.
