Installation guide - Replacing a blade
General guidance for this part type - always follow your device manual- Cut resistant gloves
- Wrench or socket for bolted blades
- Never run the device without its guard or seal in place.
- Blender blades: check the rubber ring under the blade is seated, or the jar will leak.
- 1Switch off and unplug. Unplug the appliance or remove the battery; on petrol mowers disconnect the spark plug lead too.
- 2Remove the old blade. Wear gloves. Note which side faces up and the order of any washers, then undo the fixing. Mower blades: wedge a block of wood against the blade so it cannot turn.
- 3Check the new blade. Compare length, center hole and edge direction with the old blade before fitting.
- 4Fit and tighten. Fit the new blade the same side up with the washers in the same order, and tighten the fixing firmly.
- 5Reassemble and test. Refit guards or the jar seal and test briefly before regular use.
This is general guidance for the part type, not a model-specific procedure. If the part does not fit without force, stop and recheck compatibility.
