It "catches" the chain if you have the misfortune of throwing one. It is a safety feature for both you and the saw. A flying chain has an amazing amount of destructive force.
i understand they have a close relationship to chain pitchers.
serioiusly, my double dawg/roller chain catcher came today for my ms361.
i left the original catcher in place and installed the kit. looks awesome!!! any advantages or disadvantages to having both?
i understand what they are supposed to do i guess, but i can see the point of his question. looks like a flailing chain would just hit those things (especially my roller type) and just keep flailing... at least causing the rest of the chain to whip around at you.
Volks, finally got mine today even though the dealer added on the shipping charge...msrp + shipping on a part that was back ordered for a month burns my ass. Anyway, I left both on as well.
$33.65 for the dawgs/catcher, out the door. bought a couple wedges too. wedges must be really high quality cuz the were stihl!!!!
i thought i read somewhere on AS that you should take the old catcher off (don't remember why) but the bolt held somthing else in place too........i'm too lazy, er, i mean busy to search for that thread.
