Carbon Brushes - OKODOKO - 4Pc - 22 X 12.4 X 6.2mm

The frequency of replacement depends on usage and the specific tool. Inspect them when you notice a decline in performance, such as reduced power or increased sparking. They are typically replaced when they have worn down to about half their original length.

Replacing only one carbon brush can lead to uneven wear on the motor's commutator and armature. This can cause increased friction, overheating, and premature failure of the motor. Always replace them in pairs.

These OKODOKO carbon brushes are designed for specific Macallister, Hilti, and Duss models. Using them in incompatible tools may not provide a proper fit, could damage the tool, and may not restore performance. Always check compatibility.

Installation is generally straightforward and involves accessing the brush holders on your power tool. However, it is recommended to consult your tool's manual for specific instructions. Ensure the tool is unplugged before starting.

The dimensions of these OKODOKO carbon brushes are 22mm x 12.4mm x 6.2mm.

These brushes are crafted from premium materials designed for durability and resistance to wear.

Ensure the new carbon brushes are seated correctly and making proper contact with the commutator. Verify the tool is properly plugged in and the power source is active.

Check that the brushes are the correct size and model for your tool. Ensure they are installed in pairs and are not binding in their holders. Clean the commutator surface if it appears dirty or damaged.

Confirm that both old brushes were replaced. Ensure the new brushes are making firm contact. Inspect the commutator for wear or damage, which may require professional service.

Ensure the brushes are properly aligned and not causing any friction. Check for any debris within the motor housing that might be interfering with rotation.
