Hot Blanket PVC Benders only have a 90 warranty!!! If these are used improperly, such as the end of the PVC not being properly supported at the ends and the blanket is resting on the concrete while making a bend this WILL burn a hold in the side of the blanket and this is not covered under warranty. Also, after each bend, this bender should be given 10 minutes to cool. This is NOT a unit designed for consistent production bends.
This tool is NOT repairable, do not attempt to modify this product!
