Note: The machine is supplied with the grinding guard pre-installed
1. Remove the Threaded Flange (5), Disc (10) (if installed) and Spacer (6)
from the Spindle (4)
2. Using a Phillips screwdriver (not supplied), remove the three screws
that secure the guard flange to the gear housing, taking care not to
lose the spring washers located on each screw
3. Remove the guard flange and guard
4. Place the ridge of the alternative guard into the sliding-groove on the
gear housing that leads around the spindle and secures the guard
in place
5. Re-place the guard flange on top, and line up the three holes for the
Phillips screws previously removed
6. Insert the three Phillips screws with spring washers and tighten
loosely, to allow the guard orientation to be adjusted
7. Slide the guard into the desired position
8. Retighten the three screws of the guard flange
9. Re-install the required disc as outlined in 'Fitting a grinding or cutting
disc'
Note: The guard can be moved through a range of approximately 90°, so
that it can be placed between the disc and the operator at any required
work angle.
Fitting a grinding or cutting disc
Note: Ensure you have the correct guard installed for the disc you plan to
install.
1. Ensure that the Spacer (6) is in place on the Spindle (4) and positively
engaged
2. Place the cutting or grinding disc onto the spacer
Note: If using depressed centre discs, ensure that the depression is
positioned towards the spacer.
3. 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
4. Depress the Spindle Lock Button (7) and rotate the spindle until you
feel the lock engage
5. You can now use the supplied Pin Spanner (8) to fully tighten the
threaded flange. When tight, release the spindle lock button. The
grinder is now ready for use (see Fig. B)
6. To remove a disc, depress the lock button, rotate the spindle until
you feel the lock engage, and use the pin spanner to remove the
threaded flange
Fitting a wire cup brush
Note: When using the angle grinder with wire cup brushes, the guards
become ineffective and should be removed.
1. Remove Threaded Flange (5), Disc (10) (if installed) and Spacer (6)
from the Spindle (4)
2. Screw cup brush directly onto spindle
3. Depress the spindle lock button and rotate the spindle until you feel
the lock engage
4. Tighten the cup brush with a suitable spanner. Release the lock
button. The machine is now ready for use (see Fig. C)
5. To remove a cup brush, depress the lock button, rotate the spindle
until you feel the lock engage, then use a suitable spanner to remove
the cup brush
Operation
Switching on/off
Note: Do not switch the machine on/off when the disc is in contact with the
workpiece. 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.
1. Grip the main and Auxiliary Handle (2) firmly. Press the Lock-Off
Button (11) to disengage the safety lock, then press the On/Off Trigger
Switch (1)
2. To stop the machine release the On/Off Trigger Switch
Grinding
• 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, keep the tool at approximately 15 to 30° to the workpiece
surface (see Fig. D)
Note: Do not apply too much pressure to the machine whilst grinding.
Excessive pressure does not result in more effective removal of material,
but will in fact cause premature wear of the grinding disc and increase
wear and tear on the machine.
Cutting
WARNING: Always ensure that the correct guard for use with cutting discs
or superabrasive wheels is installed.
• 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. The disc might shatter
and produce projectiles that could injure the operator and bystanders
• When cutting, always keep the angle of the disc constant. Do not apply
any sideways force to cutting discs, as this might lead to the disc
becoming jammed in the cut and shatter
WARNING: Do not apply too much pressure to the machine whilst cutting.
Excessive pressure does not result in more effective or faster cutting, but
will in fact cause premature wear of the cutting disc and increase wear and
tear on the machine.
Note: The cutting disc will wear during use, and the disc diameter will
gradually reduce in size. The smaller the disc becomes, the more strain will
be placed on the motor. To avoid damage to the machine, only use cutting
discs that are within approximately 25% of the original size.
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 come into contact
with the machine housing
• Run the grinder, with cup brush or wire wheel attached, for at least 30
seconds before use to check that the 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 bend the wires out of shape and damage the
brush
Accessories
• A wide range of compatible accessories, including grinding, cutting and
flap discs, diamond wheels, wire cups and more, is available from your
Silverline stockist. Spare parts can be obtained from toolsparesonline.

Maintenance
WARNING: Always remove the plug from the mains power supply before
carrying out any maintenance/cleaning.

• 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)
