GB
• Combined or dual bench grinders should be fully assembled with both
sides fitted with wheels. Do not attempt to use such a grinder with only one
wheel installed
• Do not exceed the duty cycle of the grinder. Only use the grinder for the
maximum stated time and always allow the required switched-off cooling
period
• Do not exceed the maximum wear of the wheel stated by the wheel
manufacturer. This may be physical size reduction or, in some instances, a
maximum number of hours of use
• Ensure wheels are stored according to the wheel manufacturer's
instructions.
If you suspect that a wheel has degraded in storage DO NOT USE
• Ensure that grinding wheels are fitted correctly and securely prior to use.
Tighten grinding wheel lock nuts, secure bolts and check all clamps and guards
• After fitting a new grinding wheel, stand to one side of the grinder and
switch 'ON'. Let the grinder operate at full speed for approximately one minute
to allow undetected flaws or cracks to become apparent especially if the first
use of a wheel
• Keep fingers clear of the grinding wheels at all times. Do not work with
very small workpieces that could cause your fingers to contact the grinder or
wire brush wheel
• DO NOT attempt to use a grinding wheel for a cut off operation

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 a earth
connection. Do not attempt to use it without an earth connection.
Assembling the bench grinder
Note: This machine 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
• 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 assembled 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 & 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 and fitting a grinding wheel
Note: Only fit wheels of the correct size for this machine (see 'Specification').
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. Remove 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 & 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 machine 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 machine case
• Hot air may be emitted from the machine when in use
