Fitting the Auxiliary Handle
WARNING: Ensure operator safety by ALWAYS using the Auxiliary Handle (5). Install it at the most
appropriate position for the individual task.
1. Screw the Auxiliary Handle clockwise into one of the Threaded Holes (1) on the gear housing. Tighten by
hand.
2. Unscrew anti-clockwise to remove the handle
Adjusting, removing and installing the Guards
WARNING: The correct guard MUST be installed for each application before operation commences.
WARNING: NEVER install a cutting disc or superabrasive cutting wheel without the correct cutting wheel
guard in place.
Note: The Guard (6) must be adjusted so that it is situated between the Disc (7) and the operator. Reset the
GB
Guard if the work angle or the position of the operator changes. Seek professional guidance if you are unsure
how to operate the guards or any other safety features of the tool correctly.
Note: The grinder is supplied with the Grinding Guard (6) pre-installed.
Adjusting the Guard
1. Open the Quick-Release Guard Clamp (8) (Image A).
2. The Guard can be moved through a range of approximately 90°, so that it can be placed between the Disc
(7) and the operator at any required work angle.
3. Close the Quick-Release Clamp.
Note: If the Clamp is too loose or too tight, open completely and adjust the Clamp tightening screw.
Removing Guard
Note: Skip Step 1 if no Disc is installed.
1. Depress the Spindle Lock Button (10), rotate the Spindle (11) until the lock engages, use the Pin Spanner
(14) to remove the Outer Flange (12) and remove the Disc (7).
2. Open the Quick-Release Guard Clamp (8), rotate the Guard until the protrusions on the band of the Guard
are aligned with the notches on the gear housing, and remove the guard (Image B).
Installing Guard
1. Loosen the Quick-Release Guard Clamp (8).
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 Guard 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 (7) 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 (13).
3. Screw the Outer Flange (12) onto the Spindle. The raised center 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 (10) and rotate the Spindle until you feel the lock engage.
5. You can now use the supplied Pin Spanner (14) to fully tighten the Outer 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 Outer 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 (6)
and rotate beneath the Auxiliary Handle (5) 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 Outer Flange (12), Disc (7) (if installed) and Inner Flange (13) from the Spindle (11).
2. Screw the wire cup brush directly onto Spindle.
3. Depress the Spindle Lock Button (10) and rotate the Spindle until you feel the lock engage.
4. Tighten the wire cup brush with a suitable spanner (not supplied). Release the Spindle Lock Button. The
tool is now ready for use (Image D).
5. To remove a wire cup brush, depress the Spindle Lock Button, rotate the Spindle until you feel the lock
engage. Once locked use a suitable spanner to remove the wire cup brush.
Operation
Switching ON & OFF
Note: Do not switch the tool ON/OFF when the Disc (7) is in contact with the workpiece. Always allow the
motor to reach full speed before applying the load, and to stop completely before placing the grinder down.
Always hold the tool 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 (2).
1. To start the tool, grip the Main Handle (3) and Auxiliary Handle (5) firmly.
2. Push the ON/OFF Switch (2) forward and slightly downward until it locks in the 'I' position
Note: As a safety feature, the Sliding Safety Switch is spring-loaded so that it can return the Switch to the
'OFF' position upon touch or impact.
3. Stop the tool by slightly pushing down on the bottom part of the Slider Switch and returning the Switch into
the '0' position.
Grinding
• Use only Discs specifically manufactured for grinding operations. Stone and metal Grinding Discs are not
interchangeable; use the correct disc for the application.
• When grinding, keep the tool at approximately 15-30° to the workpiece surface (Image E)
Note: Do not apply too much pressure to the tool 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 tool.
Cutting
WARNING: Always ensure the correct guard for use with cutting discs or superabrasive wheels is installed.
Note: This tool 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 tool 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 tool.
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 tool, only use cutting
discs that are at least 75% of the original size.
Using a Wire Cup Brush or Wire Wheel
WARNING: Loose bristles within the wire cup brush can become projectiles when in motion. ALWAYS
wear suitable eye protection, adequate respiratory and hearing protection, as well as suitable gloves, when
working with this tool.
• Always check that the no-load speed of the grinder does not exceed the maximum speed of the wire cup
brush or wire wheel
10
• Ensure that no part of the wire cup brush or wire wheel can come into contact with the tool housing
• Run the grinder, with wire cup brush or wire wheel attached, for at least 30 seconds before use to check
that the wire 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 wire 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 GMC stockist . Spare parts can be purchased from your GMC dealer
or online at www.toolsparesonline.com
