Not sure if Les is just laughing at my refusal to have it on the truck. 

I couldn’t put a pile of junk like that on my truck.

One day you’ll understand.

 

 

Exactly that Mick and trying to educate kram.

I like the saw, it was nice enough to use, I will likely repair and keep it.

 

Stihls on the other hand are ear piercingly loud, and about as unpleasant noise as the german language - sounds like somone trying to vomit. Nothing against the Germans, just dont let them speak!

 

Anyway as said before, I'm a climber. I have an Echo 2511 (and its clone), Makita Uc002, Stihl 020T, all great saws that I enjoy using. 

 

This Lidl was for low cutting/roots abuse, the stuff I  wouldnt want to do to a good saw, and it did this well. I have a G372Xp clone for chogging down anything the 020T cant handle.

 

 

Next failure of the day, my newish Makita HP001 combi drill, which is the best one they do, first time using it in hammer mode, I believe the gearbox has shit itself, so that is going back tomorrow. Was it @AHPP that warned me about this drill?

Yes nothing wrong with the AV on the Lidl or ony two clones - 2511 or 372xp.

 

One interesting fact is that battery saws dont appear to have or need AV - I assumed some of the vibration came from the cutting action but it appears it is all from the engine, so they dont need it.

How come battery and electric tools like angle grinders are among the worst offenders causing vibration white finger ?

Thats interesting.. they have the specs listed, and none of the battery saws appear to have any AV mounts.

 

Comparing a Stihl ms194T, that lists 3.6m/s²

Msa190T 3.8/3.9m/s²

 

Makita UC002 5m/s². They dont do a comparable petrol top handle.

 

Husq T542i is listed 4.1/4.7m/s²

 

Echo 2511  3.5/4 m/s² and DCS2500 3.3/4.3m/s²

 

Perhaps traditional AV mounts are not so effective with motors, but there all similar.

Vibration is a oscillation X speed.

 

Electric tools should have virtually no vibration in principal, unless the motor/bearings are is damaged. It's always the attachment that induces vibration.

 

Grinders run super high rpm. If the disk is even slightly out of balance there is vibration. If the disk is perfectly balanced there should be no vibration.

 

Petrol tools oscillate by nature, due to the crank and piston system.

 

Electric saws have no inherent vibration in the motor and the chain speed (attachment) is low rpm and low mass, therefore no vibration from the attachment (unless damaged, missing teeth, improperly filed etc).

 

Long reach hedge cutters are notorious for vibration as there are oscillating elements at both ends of the shaft.

 

Any shafted tool can produce vibration of one or more of the shaft bearings goes bad.

 

My 131 pole saw developed a bad bearing, it now vibrates so much it heats my gloved hand on the trigger handle within seconds, from the friction of glove material moving with the handle.
