Always nice to get off a little early .My Monday's going great, it's 1.30pm and I've already knocked off from work .
Yeah, I tap out the filters fairly often (well when I remember). Dry blue gum is the hardest in my immediate area and is hard on chains - it's twice as hard as white oak. I broke a number of carbide chain cutters off and put backward pointing burrs on full chisel chains cutting that stuff and there are a number of species around in other parts that are harder again. Changing to semi-chisel certainly solved the damage problem but is slow going and you're soon producing sawdust as much as chips so it does clog the filter faster, no question. No such trouble when it's green. The other local species also dust up the filters when dry but without the chain damage.
Never had a problem with the oilers. TBH, I rarely actually check, other than noting that it uses 3/4 tank of bar oil for every tank of 2-stroke.
I figured you would have some problems with filters.
Do you have the maxflow on limby.
