Blade assemblies are a wear item in the JTC range of blenders. They require periodic replacement based on use. National Kitchen Equipment recommends inspecting blade assemblies weekly according to the instructions below.
Contact us at 1300 767 146 or [email protected] if you need assistance with your blade assembly.Check for nicks, cracks, or gouges in the outer surface. If any are present, replace.
Inspect the blade assembly gear for signs of wear. The teeth of the gear should be deep and have continuous edges.
Inspect the bottom of the blade assembly below the gear. If you see that any part of the seal is torn, missing, or lifting, replace the blade assembly.
Rotate the blade by hand, feeling for smooth, consistent, light resistance.
Place the gear of the blade assembly between your index finger and thumb and push up and down (vertically) on the gear. If any vertical movement is detected, replace the blade assembly immediately.
