Warranty

12-Month
Warranty.

Every WVI hydraulic breaker is backed by a 12-month manufacturer's warranty covering defects in materials and workmanship. Extended coverage available for volume orders.

All WVI hydraulic breakers carry a 12-month warranty from the date of shipment.
Warranty covers manufacturing defects in materials and workmanship under normal operating conditions.
Wear parts — chisels, bushings, retainer pins, and diaphragms — are consumables and not covered.
Warranty is void if the breaker is operated outside the specified excavator weight range.
Damage caused by improper hydraulic oil, contaminated oil, or incorrect oil flow/pressure is excluded.
Unauthorized modification or disassembly by non-WVI personnel voids the warranty.
Extended warranty (up to 24 months) available for orders of 10+ units — contact sales for terms.
