Ok quick update. Had reply from a UK dealership.
”Thanks for your email. We do not have a manual for the C3 that contains the information you need unfortunately.I think going direct to Felco will be the best way to get the answers you require”.
Credit for a reply, but it has no information, no offer to follow up and contact Felco themselves. A lot of Felco dealerships are gardening based and if I was asking for secateur advise, I think they would have it. However, if you are selling a product I expect the literature to be available from Felco and the dealer to have contact with the technical/sales department of the producer. I have repaired, demonstrated and sold quarry crushers in my past life, and those boys (and girls) make you work for a sale, you have to know everything, and if not you find out about it and get back.
America has a name for customer service, anyone know a Felco dealer who knows his products? On a lighter note, do you think customer service in the US is better? That could be amusing…..
