Hi,
I'm trying to locate a set of piston rings for a Promac 610.

I've identified the chainsaw by some web pics I've found.

From phone discussion with Bruce just now, I believe the part number I'm looking for is 94132.

The rings are the thin ones, 0.75 mm thick and the piston is 47 mm dia.
Also, where can I get an operator's manual for this model.

I have a new set of wide rings for the later Promac. Same bore size and Part number 94133, if anyone is interested.

I'd appreciate any help.
Many thanks,
John
