Note 1

Leading Edge wind turbines - LET will supply ‘non-wearing’ parts at no cost. For minor component failures, replacements may be sent directly to the customer / dealer for replacement by them. For more serious defects we may suggest a ‘return-to-base’ arrangement for replacement or repair.

In these cases, the purchaser will be responsible for taking the wind turbine off the tower/mast and paying the return carriage costs.

For the LE-300, during the first two years of the warranty period any component found to be defective in material or workmanship will, at the discretion of LET, be replaced or repaired at no charge. For the remaining three years of the warranty period, LET will supply ‘non-wearing’ parts at no cost. However, LET reserves the right to charge for any fitting of parts supplied during this three year period.

Where a turbine is to be replaced, it must be returned to LET before the replacement unit is despatched. Should the product prove to be irreparable, LET reserves the right to substitute an equivalent product, if available.

Your turbine must be installed and operated in accordance with the guide. Failure to do so will result in this warranty becoming null and void. Any unauthorised modifications to the turbine design will void the warranty and may compromise the safety of the machine.
