We note that you clean the filters out every 2,500 miles. We believe in the 20 HP. Instruction Book it states that the filters should be cleaned every 5,000 miles. At the present time you will notice that B.J. is suggesting that the cars run in France are receiving a different treatment to what we recommend in our Instruction Book. We therefore would like you to carry out the periodical [strikethrough]instruction[/strikethrough] inspection agreed to in the Instruction Book. Hs.{Lord Ernest Hives - Chair} | ||
