I just lost Internet service for 3 hours... right in the middle of an Ebay transaction.
Dunno which is worse? We have gotten so dependent on technology...
Everything slams to a halt when it fails.

I don't want to beat the issue to death, but something came to mind after my post and when someone said about the piston installed 'backwards'. Used to be, at one time and I don't know if the technique still is in use, but race car builders used to taper the piston bore slightly so that the piston would be tighter at the top of the stroke than at the bottom. The theory was a better 'seal' at that point. If you could obtain the engineering drawings of the handpiece, which is doubtful they'd release those, this would answer that question. Perhaps the design of that handpiece incorporates a tighter seal of the piston on the forward or backward(?) stroke. As I don't have a handpiece, I couldn't measure such. But, that's a problem that the maker should solve. Those handpieces aren't free, and you shouldn't have a problem at all. Keep us posted.
I remember you posted this thread time ago:

Probably this is the cause of your problem and maybe is not just a problem of the handpiece but of the unit contamination too.
Good Luck!!!

I've got one but mine only has 6 filters in it. Still didn't work. Water built up into the hose until it reached a level that the air pushed the whole slug into the 4th filter and I'm sure it got into the last 2 as well.
I quit using it and bought a small oiless compressor, but the GMax never worked right after the above. Probably got the same problem as yours does. I bought a new 901 but things only improved slightly.
Gotta love GRS. Josh and Shane Rock. I overnighted the equipment yesterday. Arrived just before noon today. Just got the message it's already been picked up by FedEx for overnight delivery to me tomorrow. That is what I call top shelf customer service. DJ you have some great people working for you.
I'll update with what was wrong as soon as I find out.

The graver match hoses were clean, but after 3 years if heavy use eith an unmsintained compressor it was dirty. No oil in the internal lines. The maestro mysteriously fixed itself in transit. The 901 had a mushroomed piston. It was replaced with the new heavier model. My monarch had a broken anvil. Wonder if I should engrave softer guns? They cleaned my filthy pedal. So, I believe I'll be ok for another 3 years. Or I can take up maintenance...

Concrete floors...?
I began with a wood tongue & groove floor, extended the shop with a concrete floor - and within a month I was looking for something to cover it.
The "accident" that made me start looking for something better - cost me around $1,000.
Since then I have always had either wood or linoleum shop floors!
You may have gotten off easy?

I've had the anvil fail several times with the Monarch. I did some Beta testing for GRS and they fixed the pin that held the anvil in place.
These days, I've had a prototype 901 and a prototype Maestro that has run for what seems like centuries.
My old GraverMax (brand new in 1991) and Monarch has a squillion hours on it and still stroking.

Maybe you should get a Magnum Handpiece - it's their one for heavy duty work. Also works great for light duty. I have a Magnum and a Monarch and I feel that between them they overlap the standard 901's power range. The Monarch will go lighter than the 901 but not quite as heavy. The Magnum won't go quite as light as the 901 but goes much heavier.
When I use my GraverMach I normally use whichever handpiece I was using last, unless I need to do some fine shading (Monarch) or deep and heavy cutting (Magnum). For Lindsay users the Magnum is like putting in the Titanium piston.

Glad to hear that it was, in part, a mushroomed piston, but not glad to hear of that problem in the first. Sometimes, several factors are at work. It's good hear of 'problem resolved', and, fortunately, a staff that was able to take care of the problem. If I ever obtain such handpieces, I'll certainly keep in mind your experiences. The mushroomed piston was why interference was felt. The cracked anvil didn't help, either. Thanks for keeping us posted.
