Stihl HT 101 pole pruner sprocket

[bradstow42]

I'm in the process of fitting a new sprocket to this Stihl pole pruner. The retaining screw appears to have a reddish residue on the threads just under the pan head. Not having a service manual, could anyone advise whether a touch of thread locker should be applied.

 

Thanks in anticipation.

I use Loctite on mine. I found once that the sprocket came loose when I'd let off power and dropped the chain onto a lump of wood at the same time. Probably the screw wasn't tight enough, but I removed it, applied Loctite and retightened to be on the safe side.

Thanks, Pedroski. Sounds like good advice.
