Attn – Warranty Claims

In the case of Alternator or Engine replacement, Grandwatt will follow up to determine the best course of action with regards to return of replacement parts prior to shipping.


Parts needed for warranty work can be ordered directly from Grandwatt. Note: You are responsible to pay your parts invoice on time, even though this might be warranty. Warranty Credit/Reimbursement will take place once the claim has cleared Grandwatt Management review and also the final Factory Evaluation. (This process can take 30-60 days for review and is not guaranteed that service, or parts are claimable under warranty).


When needed, the factories may release a service bulletin to address a potential issue discovered in the field. While these TSB’s will not typically involve taking a unit out of service, it is important that they be addressed if your unit(s) fall within the scope of the TSB. When a TSB is issued, you will receive instructions on how to obtain the necessary parts (if applicable) and the allotted labor time to bill back for applying the TSB to your unit. Warranty claims from a unit failure where a TSB had not been implemented could be denied.


Grandwatt reserves the right to inspect any unit under warranty claim. We therefore suggest you keepcopies of all warranty claims documents and maintenance service records should any question come up. If there is need for inspection, we will ask you NOT to ship parts back and to have them available along with the unit. All routine as well as non-routine service should be documented for every unit obtained from Grandwatt. These service documents should include the date of service, Model and Serial (or inner companyasset ID with a cross reference), Hours on unit at time of service, type of work done, list of materials utilized (with part/model#) and final checkout. It is important to document Filter part#’s (Manufacturer of filter and filter part#, Oil Manufacturer and type). Warranty claims resulting from lack of proper maintenance, or no documented maintenance could be denied. (Periodic service stickers without backup will not suffice). PLEASE HAVE COPIES OF ALL SERVICE RECORDS AVAILABLE IF REQUESTED.


The more information sent in up front, the faster the claims process will go. We typically see a 30-60 day claim turnaround process once submitted to Grandwatt Warranty Dept. If the unit is owned by you (or your company), then a reimbursement may come in the form of a check, or a credit against money owed to Grandwatt. Our Credit Department, will work that out with you.

If the unit is 3rd party (one of your customers, or a service referral, you have 2 choices….

1)Hold the unit until after the claim is approved and then paid for by Grandwatt

  • a.You may choose, on your own to hold off completing the work until the claim is approved –depending on the claim and its severity.

2)Have the customer pay for their unit and once the claim is approved, issue them a credit.

  • a.We would suggest this if the unit is needed back in the field quickly.

We hope this document and the accompanying policy sheets and claim forms will have made it easy for you in case you need to submit a warranty claim.
