View Full Version : Quick question about Stihl attachment maintenance

05-28-2011, 04:05 PM
I just bought the fixed hedge trimmer attachment for my KM 90 a month ago and have only used it about five times since then (I've been out of town a lot). I see that it has ports where you can pump grease into (two bolts with pictures of grease guns cast into the metal next to them), my question is about how often should I add grease to these ports? I bought the attachment off the rack at my dealer but never got an operators manual for it. Thanks for any info you can provide.
