Maccullocoh "tool less tensioner"

[mad4x4]

First of all bit new about here...

 

We bought about 2 years ago a mucculloch 842 X Series Chainsaw with toolless tensioner on the bar. No regardless of what we do the chain slakens off very quickly ( 1/4 to 1/2 a tank of fuel). Can we do awa with the toolless bit and convert to 2 nuts. If so is there a kit or can some one give me an idea of what I need

Firstly, welcome to Arbtalk.

 

secondly, your McCulloch 842X saw.

Although this is very much a domestic saw there is no real reason why the toolless adjuster should not hold the bar forward, maintaining tension.

I think the problem may be more due to tensioning technique.

 

The bar on any saw has a bit of up and down movement at the tip when not tightly clamped. Usually the chain slackens as the tip moves upwards, which it tries to do naturally in work. The toolless adjuster will not provide sufficient grip to stop this.

 

Many operators who are unaware of this, tension the chain and clamp it with the weight of the bar hanging down. When put into work it then slackens.

If you ensure that the bar tip is held up as you tighten the side cover you will prevent further movement in work and may solve your problem.

 

Failing this, the standard 2 bolt side cover from a 738 should fit this saw and will set you back around £26.00.

I had exactly this problem with the toolless tensioner on my Husqvana 435 until I read your (I think it was your) previous reply on this subject. I took your advice and have had no more problems. Thankyou.

Tighten it finger tight , hold saw by back handel drop the bar tip onto a tree but , log or similar this will push it up .now tighten . This works with any type of saw .

Thanks for the good rep, coppiceer, but it wasn't me!

 

This is the first time I have replied to this sort of problem.

Sorry should have said adjust , then tighten .

Tried that today and it seems so much better. Thanks Lads

I just lift the end of the bar on my 345e with one hand so that the weight of the saw is on the bar and then tension. Works perfectly.

I brought this up some time ago - found out just through trial and error but seems it is common practice with those that know.
