Intended Use

Bench-mounted grinder for light to medium duty grinding tasks on metal workpieces, such as
sharpening drill bits and cutting/shaping tools and preparing metals for welding. Not intended for
commercial or industrial use.
Unpacking Your Tool
• Carefully unpack and inspect your tool. Familiarise yourself with all its features and functions
• Ensure that all parts of the tool are present and in good condition
• If any parts are missing or damaged, have such parts replaced before attempting to use this tool
Before Use
WARNING: ensure the tool is disconnected from the power supply before attaching or
changing any accessories or making any adjustments.
Note: This tool is earthed and must only be connected to mains with an earth connection. Do not
attempt to use it without an earth connection.
Assembling the bench grinder
Note: This tool must always be securely mounted to a strong, stable workbench (fittings not
supplied).
Attaching the spark arrestors with eye shields
• The grinder should never be used without the supplied Spark Arrestors (5) and Eye Shields (15).
Attempting to use the grinder without these correctly fitted is highly dangerous and could result
in severe injury to yourself or others around you
• Ensure the Spark Arrestor is installed with the bottom edge about 1.5mm from the wheel
surface; never let it exceed 2mm. Ensure the supplied spring washers are assembled with the
Spark Arrestors so vibration will not cause the fitting to loosen and allow the Spark Arrestor to
contact the wheel
• Angle the Eye Shield at the correct angle to maximise protection to your eyes in use and tighten
with the Eye Shield Adjuster (4). Safety glasses must always be worn in addition to the protection
offered by the Eye Shield
Attaching the tool rests
• The grinder should never be used without the supplied Tool Rests (13). 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
6
• Attach the Tool Rest with the Tool Rest Adjustment Knob (12) and position the edge of the Tool
Rest that is closest to the wheel at a distance of approximately 1.5mm
• Ensure the supplied spring washers are assemble with the Tool Rests so vibration will not cause
the fitting to loosen
Note: Each Tool Rest can be adjusted to best suit the work to be performed. Always ensure the Tool
Rest is securely tightened before use.
Note: As the Grinding Wheel (9 and 14) wears, it will be necessary to adjust the Tool Rest and Spark
Arrestor. The gap should be no more than 2mm at all times.
Removing & fitting a grinding wheel
Note: Only fit wheels of the correct size for this tool (see 'Specifications').
Removing
1. Reposition or remove the Spark Arrestor (5) and Tool Rest (13) if necessary
2. Remove the Wheel Guard (7) by removing the three Wheel Guard Nuts (2) and Wheel Guard
Bolts (8)
3. Wearing a protective glove, hold the Grinding Wheel (9 or 14) by hand and unscrew the Grinding
Wheel Nut (17). Remove Grinding Wheel Flange (16) ensuring that any additional washers are
retained for the new Grinding Wheel
4. 4Remove the old Grinding Wheel; clean the spindle and parts ready for the new Grinding Wheel
Fitting
1. Check the condition of the new Grinding Wheel (9 and 14); ensure it is not damaged or cracked.
Also ensure it is of the correct required grit before fitting
2. Fit the new Grinding Wheel on the spindle ensuring any required washers are refitted
3. Refit the Grinding Wheel Flange (16) and Grinding Wheel Nut (17)
4. Reassemble the Wheel Guard (7), Spark Arrestor (5) and Tool Rest (13)
5. Before use, run the Grinding Wheel for a minimum of 1 minute to ensure it operates normally
Note: If the tool does not operate normally after refitting a Grinding Wheel, repeat steps in
'Removing' and 'Fitting' .
Note: During reassembly, do not over-tighten the Grinding Wheel Nut. Doing so will make it
difficult to remove when disassembled at a later date, and can damage the wheel, which may crack.
Do not use excessive force.
Pre-operational checks
• Always check that all parts or attachments are secure, and that rotating parts will not contact
guards or tool case
• Hot air may be emitted from the tool when in use
Operation
WARNING: Always wear suitable personal protective equipment, including eye, hearing and
respiratory protection, when operating this tool.
WARNING: Be aware that the cast metal motor housing may get hot during use.
Switching ON & OFF
Note: Do not switch the tool 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 tool ON, press the 'I' on the ON/OFF Switch (11)
• To switch the tool OFF, press the 'O' on the ON/OFF Switch
Duty cycle: Do not exceed a maximum operating time of 30 minutes in every hour. It is
recommended to keep to an operating time of no more than 10 minutes to reduce risk of damage
to the tool from over-heating.
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 (13) 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 especially if the Spark Arrestor or Tool Rest is incorrectly
fitted. 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 amounts 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
