Changing AV mounts

[D A Tree Surgeons]

I had a new customer in the shop this afternoon. He asked about chainsaw servicing, and asked if I changed the AV's on every service, as apparently his current dealer does.

 

I think this is a bit over the top, I check them of course, and change if required.

 

Do any of you have your AV,s changed on routine servicing?

 

In Answer to your Question

We do not have are AV Mounts changed on a routine Service:001_smile:

And I think you have misunderstood the process of HAVS monitoring.

Why would you want to test the mounts individually? You don’t test the individual mounting, you test the machine and thus all the mounts at the same time.

 

There is no interpretation of the results, the machine produces a value, that then falls in the parameters or not, simple as that.

 

When you presume to say that I am in favour or changing AV mounts at each service you are wrong to say that. It’s the narrow view of someone fixing saws. Replacing AV mounts is a good idea where appropriate but its far from the whole story, you need to take a step back and see the AV mount as a part of HAVS monitoring

 

What I am in favour of is not having people with hands in a state like mine. A couple of decades ago saws were a lot cruder than now and HAVS was unheard of and it has taken its toll on cutters of that generation.

 

 

I do understand the process of HAVS monitoring, but as yet it is not something that is done in the chainsaw service shop, so as a narrow minded mechanic it is something I leave to designers and testers.

 

What is done, or rather, what I do, is to check each AV individually to determine their serviceability and, if in my judgement they need replacing.

Apart from replacing them as a matter of course, that is all I can do.

 

The decision to replace as a matter of course, or as required, is the subject of this thread.

 

If we were to have to carry out HAVS tests on a service, then we would indeed have to interpret the results. The test would show vibration levels which would be compared to the levels of a new saw. We would then have to identify what was causing the excess vibration. This would involve checking the AV's individually as well as other factors.

 

I have to admit to being a little wiser now as to why some customers may feel they need the AV's replaced in order to satisfy their HSE policy. This is something I had not previously considered. Thank you to all contibutors to this thread for that.

 

And I do sympathise with you over your shot hands, Treequip. Hopefully the strides forward in AV technology and HSE directives will save the younger generation from similar problems.

As a narrow minded tech I just stare at the saw all day before deciding that stuff the customer it look ok to me. And send them an invoice for a days labour.......

[GardenKit]

As a narrow minded tech

 

You too??

[Rich2484]

You too??

 

Yeah definatly.....

 

What about you spud?

[spudulike]

Yeah definatly.....

 

What about you spud?

 

Hi...Mr thicky here - I stare at the saw and the saw stares back at me.......so I boil its bits in me ultrasonic cleaner - there that learnt him:lol:

 

What are AVs anyway -guess Audio Visuals???

 

Everybody knows Husqvarna have the best AV mounts:001_tt2:

AV systems have moved on greatly since then though, and it's your generation (old) trying to tell my generation (young, youthful and eager) to avoid white finger and carpal tunnel, but the time stuff is stupid! 20 mins on a strimmer/brushcutter/saw/blower means nothing will get done, and for those payed a set day rate, the idea is to get done and in the pub as fast as possible!

I rigorously inspect AV mounts to the best of my ability. This includes paying attention to how our saws "feel". I look after 29 machines including blowers/pole saws ets

 

I work wit the saws I fix, so I can gauge (often by comparison & a 2nd opinion) there condition & act when needed.

 

The ones most frequently replaced are for the 200t's front handle, which, when replaced, I will replace the rear AV rubber at the same time.

 

Hope this helps

Yes AV systems have moved on, but have they moved far enough?

 

When I was youg and full of vim and vigor I destinctly remember the old boys telling us not to be so keen to jump on that big saw, they were the ones with hand problemsand and we largely ignored them just as you are doing now.

 

The only diference now is that thses days its not just what some old geezer said which we could largely ignore, the problrm has been identified reaserched and quantified so you will be ignoring the old geezer and a pile of science:laugh1:

 

I dont think you will listen but you will probably remember, perhaps we are all doomed to repeat the mistakes of others.

 

Geting in the pub as fast as possible is all well and good but dont run so fast you leave your health behind
