Each manufacturer has slightly different warranty terms. this page should help in clarification of what is covered by warranty and for how long.
Remember that a manufacturers Warranty covers the machine and its components against faulty parts and/or workmanship. Parts are not covered for wear, so items such as belts and blades are generally excluded from warranty.
Most warranties are only valid if the machinery is looked after and serviced in accordance with the instructions, so may be void if the servicing is not up to date and documented.
Many manufacturers do not offer any guarantee on machines used by professionals, although some do offer a limited guarantee.
