What are your warranty terms?
The equipment is warranted for 1 year of normal operation from the date of commissioning or 18 months from the date of post-shipment, whichever occurs first. If any part has a proven manufacturing defect during the warranty period, it must be replaced or repaired free of charge. This does not cover any damage or failure resulting from misuse/abuse or failure to follow operating instructions and training. The warranty does not cover normal wear and tear and consumables. If damage or failure occurs due to causes beyond the control of the supplier, the warranty does not apply.
