Attaching the tool rests
• The grinder should never be used without the supplied Tool Rests (4).
Attempting to use the grinder without the tool rests, or with the tool rests
incorrectly fitted, is highly dangerous and could result in severe injury to
yourself or others around you
• The tool rests should be attached to the Wheel Guards (3), using the nuts and
bolts supplied
• The tool rests can be adjusted to best suit the work to be performed. Always
ensure that the tool rests are securely tightened before use.
• As the Grinding Wheel (1) wears, it will be necessary to adjust the tool rests. The
gap between the wheel and the rest should be less than 3mm at all times
Before Use
• Always check that all parts or attachments are secure, and that rotating parts
will not come in contact with the guards or machine case
• Be aware that the cast metal motor housing may get hot during use.
• Ensure that any ventilation holes are not obscured in any way. Hot air may be
emitted from the machine when in use
• Always wear suitable personal protective equipment while working with this
tool. Use of this machine requires ear defenders, safety goggles, gloves, and a
breathing mask
• This tool is earthed and requires an earthed 3-pin socket
• This tool is not suitable for outdoor use
Fitting a grinding wheel
• Only fit wheels of the correct size for this machine (see Specifications)
• Remove the screws in the end cover of the Wheel Guards (3), and remove the
end cover
• Remove the retaining nut from the centre of the grinding wheel
• The grinding wheel can now be removed and replaced
• Ensure that the retaining nut and end cover are replaced and securely tightened
before use
Note: Over-tightening the retaining nut can cause the wheel to crack. Do not use
excess force
Operating Instructions
Switching on/off
Note: Do not switch the machine on/off when under load. Always allow the motor
to reach its full speed before applying load, and to stop completely before leaving
unattended
• To start the machine, press the part of the On/Off Switch (5) marked 'I'
• To start the machine, press the part of the On/Off Switch (5) marked '0'
Note: The duty cycle of the bench grinder is a maximum 30 minutes continuous
operation. After 30 minutes continuous operation the grinder will require 30
minutes to cool before reusing. The cooling time is the ideal time to clean up and
remove the large amount of dust created by the grinding process.
Grinding
• Do not push the workpiece into the grinding wheel as you grind causing the
grinding wheel to slow. Instead allow the grinding wheel to maintain full speed
and apply very minimal pressure
• Do not use grinding wheels that are damaged or have worn down more than
25% from their original size
• Always hold work against the Tool Rest (4), and grip with both hands. Position
yourself so you have a comfortable grip on the workpiece without being
excessively close to the grinder. It is critical your clothes have no loose strands
of material especially on your arms and close to your hands that could be
caught by the grinding wheel forcing your hand into the grinding mechanism
• Do not attempt to work on material that is too small to grip securely
• Always refer to wheel manufacturer’s literature before use. Check that the
wheel is suitable for the material that you intend to work
• Metal grinding may produce sparks. Ensure that you are properly protected, and
that any flammable materials are removed from the work area
• When grinding, the workpiece will quickly become hot. It may be necessary
to quench the work in water to prevent heat damage. The fine-grade grinding
wheel will produce less heat and may be safer to use for some materials that
are easily heat damaged
• Some materials may contain trace amount of toxic materials. If you are unsure
of the composition of the workpiece, it is recommended to remove grinding dust
frequently and always wear suitable respiratory protection
• Metallic dust can damage other tools if allowed to accumulate by vents and be
drawn in when the tool is operated
• When grinding has finished for the session, remove dust and vacuum work
area and tool
Maintenance
WARNING: Always remove the plug from the mains power supply before carrying
out any maintenance/cleaning.
Cleaning
• Keep your machine clean at all times. Dirt and dust will cause internal parts
to wear quickly, shortening the machine’s service life. Clean the body of your
machine with a soft brush, or dry cloth. If available, use clean, dry, compressed
air to blow through the ventilation holes
Note: There are no user serviceable parts within the grinder body.
Disposal
Always adhere to national regulations when disposing of power tools that are no
longer functional and are not viable for repair.
• Do not dispose of power tools, or other waste electrical and electronic
equipment (WEEE), with household waste
• Contact your local waste disposal authority for information on the correct way
to dispose of power tools
