User error or maufacturing defect.

[Pinkfoot]

Just wondering really ,how many chainsaw saw failures are due to user error , I. E. Bad maintanace , bad practice , abuse or bad design and build quality. ?

[Mick Dempsey]

Define failure.

[treequip]

Some will be down to design and others to error

 

A clearer question is needed

[Pinkfoot]

Define failure.

 

Any component that prevents the tool from being used for its intended purpose through breakage , seizure etc. In other words , if it stops you working and has to be repaired.

It's all user error I think. The back handle fell off, well it's your fault as you bought the piece of junk and used it.

Piston scoring seems a major issue at the moment; lean seizing too...

 

Bad mix (user)/ ethanol (3rd party) / other?

 

Autotune, er, hum, ssshhhh.

 

Never used to get these issues with old school saws.

[Mick Dempsey]

In all fairness, after 20+ years of chainsaw usage, the only disappointing "not my fault" failures was two 357s blowing up long before they should have. Everything else has been my misuse/poor maintenance. Or reasonable wear through age.

(Only stihl /husky btw)

Score one failure to auto tune and one to very difficult to start unless you have the right technique or are very lucky, it is improving with running though so possibly some build quality issue.

Strange but the 3 home owner and a Chinese saw I use between work and home have all been faultless and have all cut about the same amount of wood as the pro saws.

We tried a container load of Chinese canopied silent diesel generators. Most where dead within a few months. We had a demo which has the oil changed at less than 50 hours and never gets more than 70 % load and is still going strong after 10 years so it does make you wonder if it's operator error. The genuine yanmar is 3 times the price and smokes like a pig when cold unlike the who flung dung. Thieves don't seem so keen on the Chinese stuff either. There is a good dealer network every scrap yard in the country has one on the pile.

Every machine which breaks is always a manufacturer defect....

 

Not my fault the saw wernt designed to cut stones!

No my fault that tractor is too wide!

Not my fault those electrics cant handle abit of water!

Not my fault that plastic cover doesnt stand upto being hit with a hammer!

Not my fault...
