Call 01908 660663 and ask for the Service Department. They will triage the problem and if a fault is diagnosed they will provide you with a returns number and a form to be completed which should be faxed back to them on the number they provide. They will arrange to collect your product (only from a business address otherwise you are responsible to pay the shipping cost), repair it and return it free of charge. Please Note, you will require to enclose your Toolstop invoice and completed returns form with the returned item. The Hitachi warranty is only valid in the UK, therefore any items being shipped abroad need to be returned to the UK for repair at the customer’s expense.
