Slacken bar holding nuts, then tighten the chain tensioner screw so that when the saw is sitting flat, the nose of the bar just starts to rise, that's a useful indicator for correct chain tension.Then re-tighten the nuts holding the bar in place! Chain should not be coming off the bar! Also once tension is correct if the chain is moving whilst the engine is idling then the engine idling speed needs reduced, another little screw for that.
As a former frequent chainsaw user and an occasional one now, who's done several training courses and refreshers, I'd say take a course or at least shadow someone who is qualified for basic maintenance (sharpening/filter cleaning/bar replacement etc) and cutting techniques and definitely get PPE - protective trousers and boots most important for protection of limbs, helmet with visor and earguards for eyes/hearing.....obviously. Keep your thumb around the handle and not on top.
Most serious accidents with chainsaws in the industry at least these days are from hung up trees, i.e. the one being felled gets stuck in the neighbouring trees, people then start cutting the neighbouring tree which is holding the weight of the first one and all kinds of dangerous things can happen. It's crush injuries rather than cut injuries that are the most common serious injuries/fatalities in the industry. Kickback is largely protected by the chainbrake just ahead of the handle, older saws didn't offer that protection. Outside the industry stats for farmers having accidents with saws is bad, they tend to crack on with tasks without PPE or training, used to doing everything themselves.
Clearing windblown trees (fallen but still rooted) is also very dangerous especially if done incorrectly, tremendous stored forces in the stem of a rooted fallen or leaning tree can be released very quickly when cut.
Go to respect chainsaws, not saying dont use one or get one but get PPE and some basic training if you do.
Jeez... don't encourage him!
As a former chainsaw instructor, the simple advice is don't, don't, don't. Don't pick up a chainsaw without training and correct PPE.
And if one did do the training, one would know that trying to cut a sofa is a ludicrous idea. It will be made of a whole variety of materials unsuitable for cutting by chainsaw. The only certainty will be that both the user and the saw would come to grief.
Find something to get annoyed about, get a sledgehammer, get the sofa, and then just let the tension out ...
