PREPARATION

Before you start – Safety information

• Always use eye protection conforming to a recognized standard (for example: ANSI Z87.1) – (CSA or ANSI).
• Always wear a mask or respirator when dust is generated.
• Keep bystanders out of the work area when operating the tool.
• WARNING! Always ensure that the work area is free of flammable materials, liquids or gases, as use of this tool may create sparks.
• Do not wear loose clothing or jewellery. Keep your hair tied up.
• WARNING! Immediately replace the grinding wheel(s) which are cracked. Do not overtighten the shaft nuts.
• NEVER grind with the side of the wheel. Grinding should only take place with the front part of the wheel.
• NEVER apply pressure to the workpiece when the grinding wheel is cold. The wheel should be heated by applying the workpiece gradually.
• NEVER use the grinding machine without the wheel guards. Keep thumbs and fingers away from the wheel.

Before you start – Protection against electricity
In the event of a malfunction or short circuit, grounding provides the path of least resistance for electricity and reduces the risk of electric shock to the operator. This tool is equipped with an electrical cord that has an equipment grounding conductor and a grounding plug. The plug MUST be plugged into an outlet that is properly installed and grounded in accordance with ALL local codes and regulations.

DO NOT MODIFY THE SUPPLIED PLUG. If it does not fit in the outlet, install the appropriate outlet with the assistance of an electrician.

Improper connection of the equipment grounding conductor may result in an increased risk of electrical shock. The conductor with green insulation (with or without yellow strips) is the equipment grounding conductor. If it is necessary to repair or replace the electrical cord or plug, DO NOT connect the equipment grounding conductor to a current-carrying terminal.

CHECK with a qualified electrician or service personnel if you do not fully understand the grounding instructions, or if you are unsure if the equipment is properly grounded.

EXTENSION CABLE USE

Use only 3-conductor extension cords with 3-pin plugs and 3-socket outlets that accept the tool’s plug. Repair or replace damaged or worn cables immediately. Ensure that the extension cord is properly connected and in good condition. Do not use damaged extension cords. Always replace an extension cord that is damaged. When using an extension cord, make sure that it is sufficient to carry the current that the tool will draw. An undersized cable will cause a voltage drop in the line, resulting in power loss and overheating. Before connecting the motor to the power line, make sure the switch is in the OFF position and that the current is rated with the current on the motor nameplate. Operating at a lower voltage will damage the motor and is not covered under warranty.

UNPACKAGING

1. Unpack all the contents of the package and place them on a flat and stable surface.
2. Remove all packing materials and transport devices (if any).
3. Ensure that all contents of the package are complete and free from damage. If any component is missing or if any component has been damaged during shipment, contact your local dealer. Use of a damaged or incomplete product poses a risk of injury and property damage.
4. Ensure that you have all parts and tools required for assembly and operation. This includes appropriate personal protective equipment.

BENCH GRINDER PREPARATION

Bench Grinder fixing.

WARNING: Do not use the bench grinder unless it has first been securely installed on a suitable workbench.

Place the machine on a stable and level workbench or tool stand and ensure that it is properly secured. The front of the machine should be easily accessible after it has been fixed. The power supply should be located at a maximum distance of 100 – 150 cm from the machine’s fixing point.

Assembly of the protective glass eye shield.

WARNING: Never use the bench grinder unless the protective glass has first been installed.

1. Align the slot of the protective glass arm with the slot located in the upper part of the bench grinder guard and proceed to attach using a screw and nut.
2. Ensure that the gap between the protective glass arm and the wheel is not more than 2 mm (Fig. A, B).

Assembly of the machining workpiece support surface.

The workpiece support surface shall be installed such that the gap between the wheel and the support surface does not exceed 2 mm.

1. Place the workpiece support surface against the rail of the wheel guard. Ensure that the support surface is “facing” in the correct direction. The curved corner should “face” away from the wheel.
2. Pass the screw through the slot in the rail and the mounting surface.
3. Place the groove and washer on the end of the screw on the other side.
4. Secure the screw using the knob (Fig. C)

Left wheel installation

WARNING: Before performing any wheel installation or replacement work, make sure the machine is turned off and disconnected from the power supply.

1. Remove the screws from the wheel guard and then pull it out.
2. Remove the nut from the axle using a suitable wrench. The nut on the right axle has a clockwise thread, while the nut on the left axle has a counterclockwise thread.
3. Remove the outer gasket from the shaft.
4. Place the wheel onto the shaft and once seated in position, rotate the wheel by hand to confirm that the wheel moves freely and does not contact any surface.
5. Reinstall the gasket, nut and bumper.
6. Connect the machine to the power supply, turn the machine on and allow the wheel to rotate unloaded  for one minute at maximum speed to ensure that there are no cracks. (Fig. D)

WARNING: Before you can loosen/tighten the shaft nut, hold the shaft steady using a second wrench on the brush nut.

Brush Installation

WARNING: Before performing any wheel installation or replacement work, make sure the machine is switched off and disconnected from the power supply.

1. Insert a suitable wrench into the left wheel nut to hold the pivot shaft steady, and with a second wrench, loosen and remove the brush nut. Remove the outer gasket from the shaft.
2. Place the brush onto the shaft and once it is seated in position, rotate the brush by hand to confirm that the brush moves freely and that it is not in contact with any surface.
3. Reinstall the gasket and nut.
4. Connect the machine to the power supply, turn the machine on and allow the brush to rotate unloaded for one minute at maximum speed to ensure that it is in good condition (Fig. E, Fig. F).

OPERATION

CONNECTION TO POWER SUPPLY

WARNING: Check the voltage. The voltage of the power supply must match the voltage requirements of the tool as listed on the tool’s rating label.
WARNING: Before connecting the machine to the power supply, make sure the ON/OFF switch is in the off position.

Connect the machine to a properly grounded 230 V ~ 50 Hz power supply whose socket is compatible with the machine’s plug.

SWITCHING ON/OFF

Before connecting the machine to the power supply, rotate the wheel and brush by hand to ensure that they rotate freely.

• To turn the machine on, set the ON/OFF switch to the ‘I’ position.
• To turn the machine off, set the ON/OFF switch to the ‘O’ position

GENERAL INSTRUCTIONS

1. Before each use, check the wheel and brush and make sure they are not damaged.
2. After turning the machine on, wait until it reaches its maximum speed before starting your work.
3. The safety glass is adjustable and should be positioned to provide the operator with a clear field of vision through it.
4. Hold the workpiece against the support surface and feed it smoothly and evenly into the wheel.
5. Proper adjustment of the workpiece support surfaces will provide the correct working angle for efficient grinding. As the diameter of the wheel is subject to wear, you will need to readjust the position of the support surface.

Secure the twin wheel to a horizontal, stable surface before using it. Positioning the twin wheel towards the forward end of the bench will make it easier to handle long tools.

If possible, allow sufficient space on the left side of the machine to allow easy access to the wheel.

An alternative method is to fix the machine to a sheet of plywood, which could then be held in place by suitable means on a bench or table to give the twin wheel the most convenient position; before using the machine, ensure that the protective glass is positioned as close to the wheel surface as possible to prevent sparks flying.

It is a sensible precaution to use safety glasses when using the twin bench wheel.

The machine can be used to grind profiles or virtually any cutting tool, chisels, drills, etc.

However, care should be taken not to grind a tool too hard or for too long to avoid overheating.
