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
• Place the machine onto a flat surface, guard uppermost
• Ensure that the Spacer (6) is in place on the Spindle (4) and positively engaged
• Place the cutting/grinding disc onto 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
• Depress the Spindle Lock Button (7), and rotate the spindle until you feel
the lock engage
• You can now use the Pin Spanner (8) supplied to fully tighten the
threaded flange. When tight, release the spindle lock button. The grinder
is now ready for use
• 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
• 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 or 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.
• 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
• When grinding or sanding, keep the tool at approximately 15˚ to the
work surface
• 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
Maintenance
WARNING: Always ensure that the machine is disconnected from the mains
power supply before performing any maintenance procedure.
Cleaning
• Keep your machine clean. Do not allow waste to collect on any part of
the tool. Always clean dust and particles away and never allow ventilation
holes to become blocked. Use a soft brush or dry cloth to clean the
machine. If available, blow through the ventilation holes with clean, dry,
compressed air
Brushes
• Over time the carbon brushes inside the motor may become worn
• Excessively worn brushes may cause loss of power, intermittent failure,
or visible sparking
• A spare pair of brushes is supplied with this tool. If you suspect that the
brushes may be worn, replace the brushes. There is a brush access panel
on either side of the body of the tool. Be sure to replace both brushes; do
not replace one brush only
Disposal
• Do not dispose of power tools, or other waste electrical and electronic
equipment, with household waste
• Contact your local waste disposal authority for information on the proper
