If you got questions...you can talk to THE MAN.

SID is the walking talking ENCYCLOPEDIA of ALL THINGS LITTLE GIANT!
As far as the floor question...I had my #50 on a 4" floor it did ok...but I did not do a lot of hammering..over time I believe I would have cracked the floor.
However, having said that...I did shim it with a piece of 3/8 inch conveyor belt. You can find this at any concrete supplier, gravel company etc. They usually have old dead belts laying around.
I honestly believe that makes a HUGE difference.
Use Redheads for floor anchors....do not use regular "lag" type anchors as I beleive they will pull out over time.
It always amazes me how much "vibration" can destroy the seemingly "indestructible ".
Good luck and have fun with yer new hammer.
Oh, and when you talk to SID tell him I said HI! and please ask him about the class he holds once a year. They re-buils a hammer from the ground up including pouring new babbit....
For anybody who has a Little Giant hammer, this class is an absolute "GOTTA DO"!
