Performing many varied assignments in and around factories for over 40 years,
I too have experienced (still do) what you are going through.
-Also, having taken training in various Safety, Ergonomics, OSHA, etc.,
I'm aware of various industrial injury causes.
Even so...I'm not claiming to be a Safety Expert...
Just been highly exposed to this type of phenomenon.
-What it sounds like to me is a symptom of:
repetitive stress injury...
caused by exposure of the hands to vibrating equipment.
-How long have you been using tools, such as polishers, that vibrate?
-Even though you stated that you didn't have this problem with the G110v2,
the affects of using vibrating tools/equipment are cumulative.
-Also the GG 6 may indeed have a different
'amplitude of vibration' compared to the G110v2.
Ergo...You
"feel" the numbness sensation faster, so to speak.
Eventually, if you keep on using this type of tools/equipment without proper safeguards,
you may develope/incur what's known as:
Vibration White Finger (VWF)..
-
VWF is a cumulative disorder caused by the use of vibrating tools/equipment.
There is no cure once you have developed it.
It is a nerve/blood-vessel disorder.
-When your hands are exposed to coldness your finger tips (and eventually the entire fingers)
will turn white at first; then, will turn blue upon being
warmed-up---with usually a lot pain being experienced.
Not a lot of fun...and it never, ever stops going through this vicious cycle!!
-However there are measures you can take to prevent reaching this
VWF disorder stage;
or, if obtained, can help reduce/ward-off the frequency and duration of white finger episodes.
For example:
-Use the best ergonomic tools/equipment that reduce vibration transference to the hands.
(You may have to make a serious: "which, if any, polisher is best for me and my health"...decision.)
-Use vibration absorbing gloves or pads. Gel padding is better than foam padding for protecting against vibration.
-Hold tools/equipment loosely. Tight grip sinks the ship.
-Limiting your time using a vibrating tool:
Short durations with frequent breaks---10-15 minutes each hour, for example.
-Always keep your hands warm to keep blood flowing.
If they get cold...warm 'em up as fast as posssible!
-Never smoke (or stop if you do) or use any other tobacco products...
(shrinks blood vessels)
-Caffeine, cocaine and amphetamines can act as 'triggers'.
Remove these from your diet.
-Any drugs/substances that inhibit blood flow have to be avoided.
-Exercise...Not only to maintain an overall physical fitness...
But exercise your fingers/hands to improve circulation.
-
Consultation with your Dr./Health-Care Provider is of utmost importance!!
-Stop using vibrating equipment. :dunno:
Remember: this is a cumulative disorder.
The more
you vibrate, the worse it will get.
It is, afterall, your Health & Well-being!!
-
This is a very serious situation you have presented...IMHO.
And...I hope you didn't mind me addressing it as such.
Take care!
