Installing guard
1. Loosen the Quick-Release Clamp (1)
2. Align the protrusions on the wheel guard band with the notches on the gear housing
3. Push the guard onto the gear housing and adjust position
4. Close the Quick-Release Clamp
Note: If the clamp is too loose or too tight, open completely and adjust the lever-tightening screw.
Fitting a grinding, cutting or flap disc
Note: Ensure you have the correct guard installed for the disc you plan to install.
1. Ensure that the Inner Flange (13) is in place on the Spindle (11) 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.
Note: Ensure the direction indicator on the disc top surface is the same direction as the arrow indicator on the
front of the gear casing.
3. Screw the Outer Flange (12) onto the Spindle (11). The raised centre of the Outer Flange should face
towards the disc when installing a grinding disc, and away when installing a cutting disc
4. Depress the Spindle Lock Button (2) and rotate the Spindle until you feel the lock engage
5. You can now use the supplied Pin Spanner 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, it may be beneficial to fit the Grinding Guard (9)
and rotate it beneath the Auxiliary Handle (8) purely for the benefit of protecting the operator's hand. This will
depend on the design of the wire cup brush and the operation being performed.
1. Remove the Outer Flange (12), Grinding Disc (10) (if installed) and Inner Flange (13) from the Spindle (11)
2. Screw cup brush directly onto Spindle
3. Depress the Spindle Lock Button (2) 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
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
Adjusting the swivel-action handle
Note: The main handle position of this angle grinder can be adjusted to suit the individual application and user
preference for different work positions. This increases operator safety and comfort dramatically when working
with heavy angle grinders.
1. Depress the Swivel-Action Button (3) (Image F)
2. Rotate the Rear Handle (4) into the desired position
Note: The Rear Handle rotates 90° clockwise or anticlockwise from its standard position (Image G).
3. Ensure the Rear Handle is firmly locked in position and the Swivel-Action Button has been released
Note: Change the Auxiliary Handle (8) to a position that best complements the orientation of the main Rear
Handle and suits the application.
Operation
WARNING: ALWAYS wear eye protection, adequate respiratory and hearing protection, as well as suitable
gloves, when working with this tool.
Switching on and off
WARNING: Due to this angle grinder's high power rating it is necessary to completely unwind the cable
of any extension leads or cable reels used to connect this device to the mains power supply.
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
Note: Switching off the angle grinder under load will significantly reduce the service life of the on/off switch.
1. Start the machine by gripping the Rear Handle (4) and Auxiliary Handle (8) firmly
2. Shift the Lock-Off Device (6) forward and squeeze the On/Off Trigger Switch (5) (Image F)
3. Release the On/Off 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 (Image A)
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 the Cutting Guard (15) is fitted when using cutting discs.
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
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 no less than 75% of their original size.
Using a wire cup brush or wire wheel
Warning: Always check that the no-load speed of the grinder does not exceed the maximum speed of the cup
brush or wire wheel.
• 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
