We had a franchisees training day last Saturday and one of the things that the franchisees brought up was the increasing number of jobs they had got to where the
panels in the oven have been tightened up too much, so much that they couldn’t get them off because the screws had been rounded off. I think the main reason if that some oven cleaning companies are using electric screwdrivers to tighten up the screws and over tightening them and doing so ruining the screws/nuts.
For us when we get to these it’s a case of pointing this out to the customer when we do our checks and apologising for being unable to do the full clean that we normally do.
This has been mainly on the NEFF, Bosch ovens where you need to use a T15 hex tool to get them off rather than using a screwdriver.
I learnt when I was in the RAF about how not to tighten up nuts when I over tightened a nut in the cockpit of a Sea Harrier Jump Jet. The nut overtightened and then head fell off, meaning a complete strip down of the cockpit to re tap and die the nut. So these days I check the screws are tight but don’t over do it.
We carry the T15 with a ratchet screwdriver. For me this is has always the most I have ever needed as they normally come off very easily and you just need to tighten them up so they are just tight.Google+
