Fitting the auxiliary handle
WARNING: To ensure operator safety, ALWAYS use the Auxiliary Handle (6). Install it at the
most appropriate position for the individual task.
1. Screw the auxiliary handle clockwise into one of the two mounting points on the gear
housing. Tighten by hand
Note: The auxiliary handle can be mounted to the left or right side of the gear housing.
2. To remove the auxiliary handle, unscrew anti-clockwise
Fitting a grinding or cutting disc
WARNING: The correct guard, i.e. the supplied grinding guard for use with grinding discs,
MUST be installed for each application before operation commences. If using a cutting disc,
a cutting guard for cutting discs MUST be installed for each application before operation
commences. This is a legal requirement.
Note: The cutting guard is available from your Silverline dealer as an optional accessory
(product code 847124).
1. Ensure that the Spacer (3) is in place on the Spindle (1) 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 (2) onto the Spindle (1). 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 (4) 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 angle grinder is now ready for use
6. To remove a disc, depress the spindle 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 guard becomes ineffective
and should be removed.
1. Remove Threaded Flange (2), disc (if installed) and Spacer (3) from the Spindle (1)
2. Screw cup brush directly onto spindle
3. Depress the Spindle Lock Button (4) and rotate the spindle until you feel the lock
engage
4. Tighten the cup brush with a suitable spanner. Release the spindle lock button. The
machine is now ready for use (Fig A)
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
Adjusting the grinding guard
Note: The grinding 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.
1. Loosen the clamping mechanism of the Grinding Guard (7)
2. Move the grinding guard into a position where it is located between the disc and the
operator at the work angle to be used
3. Tighten the clamping mechanism of the grinding guard
Operation
Switching on and 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.
WARNING: Switching off the angle grinder under load will significantly reduce the service
life of the On/Off Slider Switch (5).
1. To start the machine, grip the main and Auxiliary Handle (6) firmly.
2. Push the On/Off Slider Switch (5) forward and slightly downward until it locks in the
‘1’ position
Note: As a safety feature, the sliding safety switch is spring-loaded to return the switch in
the off position upon touch or impact.
3. To stop the machine, slightly push down on the bottom part of the on/off slider
switch, which will unlock the mechanism and return the switch into the ‘0’ position
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
(Fig. B)
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 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.
Maintenance
WARNING: Always remove the plug from the mains power supply before carrying out any
maintenance/cleaning.
• Keep your machine clean at all times. Dirt and dust will cause internal parts to wear
quickly, shortening the machine’s service life. Clean the body of your machine with a
soft brush, or dry cloth. If available, use clean, dry, compressed air to blow through the
ventilation holes
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
• If you suspect that the brushes may be worn, have them replaced at an authorised
Silverline service centre
Note: One pair of spare carbon brushes is supplied with this machine.
Storage
• Store this tool carefully in a secure, dry place out of the reach of children
Disposal
Always adhere to national regulations when disposing of power tools that are no longer
functional and are not viable for repair.
• Do not dispose of power tools, or other waste electrical and electronic equipment
(WEEE), with household waste
• Contact your local waste disposal authority for information on the correct way to
dispose of power tools
