Unpacking and assembling your grinder
• Your grinder is supplied with the flange, spacer, pin spanner (8) and
handle loose. Before beginning to assemble these parts, check the
condition of the grinder. If any parts are damaged or missing, have these
parts repaired or replaced before use.
Attaching the handle
• The grinder should never be used without the supplied handle (2).
Attempting to use the grinder without the handle, or with the handle
incorrectly fitted, is highly dangerous and could result in severe injury
to yourself or others around you.
• The handle can be fitted in three different positions. Threaded holes are
provided in the cast metal head of the grinder to accept the handle.
• The handle simply screws clockwise into each hole. Always ensure that
the handle is tight, and secure before using the grinder. Always use the
handle position most suitable for the particular job that is to be done.

Before Use

• Always check that all parts and attachments are secure, and that rotating
parts will not foul on guards or machine case.
• Always hold the machine, using both hands, by the handles provided.
• Be aware that the cast metal gear housing may get hot during use.
• Hot air will be emitted from the ventilation holes.
• Ensure that the ventilation holes are not obscured in any way.
• Always wear appropriate personal protective equipment for the job that
you are to do. Use of this machine requires ear defenders, safety goggles,
gloves, a breathing mask, and if appropriate a hard hat.
Operating Instructions
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.
Fitting a grinding or cutting disc
• Ensure that the spacer (6) is in place on the spindle (4) and positively
engaged.
• Place the cutting or grinding disc onto the spacer. (Note, if using depressed
centre discs, ensure that the depression is towards the spacer).
• Screw the threaded flange (5) onto the spindle (4). The raised centre
of the threaded flange should face towards the disc when installing a
grinding disc, and away when installing a cutting disc.
6
• Depress the spindle lock button (7), and rotate the spindle until you
feel the lock engage.
• You can now use the pin spanner supplied to fully tighten the threaded
flange. When tight, release the spindle lock button. The grinder is now
ready for use. (fig B)
• To remove a disc, depress the lock button, rotate the spindle until
you feel the lock engage, and use the pin spanner (8) to remove the
threaded flange.
Fitting a wire cup brush
• Remove threaded flange, disc and spacer.
• Screw cup brush directly onto spindle.
• Depress spindle lock button, and rotate spindle until you feel the
lock engage.
• A suitable spanner can now be used to tighten the cup brush. When
tight, release the lock button. The machine is now ready for use. (fig C)
• To remove a cup brush, depress the lock button, rotate the spindle
until you feel the lock engage, and use a suitable spanner to remove
the cup brush.
Switching on
• 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 placing the grinder down. Always hold the machine
securely, using both hands, on the handles provided.
• To start the machine, grip the handle (2) firmly. The safety catch that is
located on the on/off switch needs to slide backwards to allow the switch
to be depressed.
• To stop the machine release the on/off switch (1).
Grinding or sanding
• Only use discs specifically manufactured for grinding operations.
Stone and metal grinding discs are not interchangeable, use the correct
disc for your application.
• When grinding or sanding, keep the tool at approximately 15˚ to the work
surface. (fig D)
• When using a new grinding disc, do not move the machine in a forward
direction, as the disc can cut into the surface of the work. Allow the edge
of the disc to round off before grinding in a forward direction.
Cutting
• Only use discs specifically manufactured for cutting operations.
Stone and metal cutting discs are not interchangeable, use the correct
disc for your application.
• Never use cutting discs for grinding operations.
• When cutting, always keep the angle of the disc constant. Do not apply
any sideways force to cutting discs.
Using a cup brush or wire wheel
• Always check that the maximum speed of the cup brush or wire wheel
does not exceed the no load speed of the grinder.
• Ensure that no part of the cup brush or wire wheel can contact the guard,
or body, of the machine.
• Run the grinder, with cup brush or wire wheel attached, for at least 30
seconds before use to check that cup brush or wire wheel is secure, and
properly balanced.
• When using a wire cup brush or wire wheel, avoid applying excess
pressure. Using greater force will not make the cup brush or wire wheel
more effective, but will cause premature breakage of the brush wires.
