Pre-operational checks
• Always check that all parts or attachments are secure, and that rotating parts will not
foul on guards or machine case
• Ensure that any ventilation holes are not obscured in any way. Hot air may be emitted
from the machine when in use
Operation
WARNING: Always wear suitable personal protective equipment, including eye, hearing and
respiratory protection, when operating this machine.
WARNING: Always unplug the grinder from the mains supply before attempting to fit or
replace any attachment. Never fit any attachment with a maximum speed lower than the
no load speed of the machine.
WARNING: Be aware that the cast metal motor housing may get hot during use.
Switching on and off
Note: Do not switch the machine on or off when under load. Always allow the motor
to reach its full speed before applying a load, and to stop completely before leaving
unattended.
• To switch the machine on, press the ‘1’ on the On/Off Switch (5)
• To switch the machine off, press the ‘0’ on the On/Off Switch (5)
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

Troubleshooting
Maintenance
WARNING: Always remove the plug from the mains power supply before carrying out any
maintenance/cleaning.
Cleaning
WARNING: ALWAYS wear protective equipment including eye protection and gloves when
cleaning this tool.
• Keep your tool clean at all times. Dirt and dust will cause internal parts to wear quickly,
and shorten the device’s service life
• Clean the body of your machine with a soft brush, or dry cloth
• Never use caustic agents to clean plastic parts. If dry cleaning is not sufficient, a mild
detergent on a damp cloth is recommended
• Water must never come into contact with the tool
• Ensure the tool is thoroughly dry before using it
• If available, use clean, dry, compressed air to blow through the ventilation holes (where
applicable)
