Fitting a wire wheel

Your bench grinder is capable of fitting a wire wheel instead of a grinding wheel.

When fitting a wire wheel ensure the wire wheel is the correct size for the grinder and also ensure the bore size of the wheel is correct for the spindle of the grinder.

Refer to the specification section of this manual for grinding wheel and bore sizes.

When fitting the wire wheel, follow the details as described in the section ‘Changing a grinding wheel’ on how to remove the grinding wheel. Ensure to leave the inner flange on the spindle of the grinder. Supplied with the grinder are 2 small rubber washers. Fit one rubber washer on to the spindle and push all the way until it makes contact with the inner flange. Slide the wire wheel onto the spindle, ensuring the wheel is a slide fit onto the shaft, all the way to the rear flange. Then fit the second rubber washer onto the spindle and push it against the wire wheel. Fit the outer flange and securing nut and tighten the nut as described in the section ‘Changing a grinding wheel’. Assemble the grinder and test as per the details in ‘Changing a grinding wheel’.

Warning. Ensure to wear safety glasses.

How to true and dress the wheels

Dressing a wheel cleans and levels the front surface to increase efficiency of operation and prevent vibration.

1.Dressing a wheel involves the use of a wheel dresser which is not supplied with the grinder. Follow the manufacturers instructions of the wheel dresser.

2.Adjust the tool rest to allow the front part of the wheel dresser to fit between the tool rest and wheel.

3.Start the motor and move the dresser across the front of the wheel a sufficient number of times until the surface is level. It is not necessary to apply excessive force in an attempt to dress the wheel in one pass of the wheel dresser.

4.Adjust the tool rest so that it is no more than 1-1.5mm from the wheel.

5.Adjust the spark deflector to ensure the gap between the bracket and wheels is less than 6mm.

Grinder adjustments

During the life of the grinder some adjustments are required to maintain a safe working environment. Please ensure the following:

•Always adjust the eye shields to the most comfortable and most effective angle to suit the task being performed.

•As the wheels wear, the spark deflector must be adjusted to ensure the gap between the spark deflector and the wheel does not exceed 6mm.

•As the wheels wear the tool rests must also be adjusted so there is never a gap greater than 1.5mm between the wheel and the edge of the tool rest.

Maintenance

Prior to any maintenance ensure the power has been turned off and the plug is removed so that the grinder is fully disconnected from the 240V supply.

Lubrication

1.All models use pre-lubricated sealed ball bearings for the motor and do not require lubrication.

2.If the wheels do not rotate freely, the bearings should be replaced by an authorised service centre.
