Your Vehicle Warranty on having an AET Product Fitted
Alternative Engine Technologies Pty Ltd (“AET”) fully backs its proprietary products, with an industry standard 12-month replacement warranty on parts (Diesel Gas System, Mufflers, Ethanol Diesel Systems)(“AET Products”).
AET’s warranty is limited to replacing any faulty parts of an AET Product.
The AET Product Warranty is conditional on the AET Product being used and maintained in accordance with the instructions outlined in the AET Operators manual. An additional condition of the AET Product Warranty is that the owner or operator of the engine or generator ensures that it is regularly maintained as per the manufacturer recommendations, eg service intervals, oil and filter changes. Failure to follow either of these conditions will void any warranty, or warranty protection offered by AET.
Equipment Guarantee
The Equipment Guarantee is separate to the AET Product Warranty, and is an extended guarantee that AET offers its customers for engines that are still under manufacturer’s warranty.
If at any stage during the engine manufacturers warranty period it can be demonstrated that the installation of an AET Product has caused damage to the engine or generator AET will as soon as possible, where appropriate, reinstate the engine or generator to its state prior to the damage occurring. The repaired state will be consistent with the engine or generators normal expected wear at the time immediately prior to any damage occurring.
A condition of the AET Warranty is that the owner or operator of the engine or generator ensures that it is regularly maintained as per the manufacturer recommendations, for example with oil and filter changes. In addition, AET supplies an operator’s manual outlining the operating instructions and conditions of use of the AET Product. Failure by the owner or operator of the AET Product to follow the instructions outlined in the operator’s manual will void any warranty provided by AET.
