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 Inner Flange (6) is in place on the Spindle (4) and
positively engaged
2. Place the cutting or grinding disc onto the inner flange
Note: If using depressed centre discs, ensure that the depression is
positioned towards the inner flange.
3. Screw the Threaded Flange (5) onto the Spindle (4). The raised
GB
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 (3) 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
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 guards
become ineffective and should be removed.
1. Remove Threaded Flange (5), Grinding Disc (11) (if installed) and
Inner Flange (6) from the Spindle (4)
2. Screw cup brush directly onto spindle
3. Depress the Spindle Lock Button (3) 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 B)
5. To remove a cup brush, depress the spindle lock button, rotate the
spindle until you feel the lock engage, then use a suitable spanner
to remove the cup brush

Operating Instructions

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 Trigger Switch (7).
1. To start the machine, grip the Rear Handle (1) and Auxiliary Handle
(2) firmly
2. Press the Lock-Off Button (12) and squeeze the On/Off Trigger
Switch (7)
3. Release the trigger switch to stop the machine
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 C)
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 (optional accessory)
for use with cutting discs or superabrasive wheels is installed.
Note: This machine is not designed for wet 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. 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 shattering
