nents subject to wear, will be free from any defects caused by faulty materials or workmanship (“Warranty”) for a
period of 5 years from the date of purchase of the product.
2. For products (excluding Meters) which carry the “Macnaught design ”endorsement, an additional Warranty period

Warranty period of 10 years.
3. For Meters, the Warranty period is 12 months from the date of purchase of the product.

(such as o-rings, seals, springs, hoses and batteries), the Warranty period is 12 months from the date of purchase
of the relevant product.
5. For products and components which are not manufactured by Macnaught and are supplied by Macnaught under
a brand name other than “Macnaught”, the Warranty period is the longer of 12 months from the date of purchase
of the relevant product and the period of the manufacturer’s warranty.
6. The warranties contained in clauses 1, 2, 3, 4 and 5 above are conditional on the purchaser, during the relevant
Warranty period:
a. delivering to Macnaught a detailed notice setting out full details of any defect in any product and
