I have the hedge trimmer attachment.....im doing a service on the piece but have a problem....the 2 blade retainer nuts are deeply sunk into the chassis....7 mm if I'm not mistaken....very difficult to get a socket on to....most of my equipment is Stihl and this is one of the worst design flaws I have ever came across....once I get the 2 nuts n bolts out I will either use washers to push the nut higher or make the recess wider by drilling the edges giving more access
Nice one 👍✂️
Nice one, I've got a few in for sharpening at the moment, they all have a thin plate that goes between the circle washers under the white bar and the top blade. Not sure why yours hasn't got it.
Interesting I don't think ours has ever had that. I do have a newer model which now has a metal plate at the bottom probably to stop debris getting into it.
👍. An essential bit of maintenance, my ego trimmers need greasing daily . I have not replaced blades yet , the gearboxes pack in first. 😐
Needed this while ago..😊
Thanks, would have been good if you lifted out the cam drive too, 1, to check the wear, and 2 clean out the greese etc.
Had mine apart but saw no way to remove cam drive.... How to do that?
@@Tropazio Once the under side (blades etc) have been removed, this free's up the bearing and cam on that side. Then flip it, remove the black handle on the otherwise. You'll see a nut holding the other side of the cam (spur) drive. Undo the nut and the cam spur drive can now just fall out. There is then a bearing on that side too, check for wear. Been a hold up for spares with Stihl, but now back on line. I replaced cam and bearings.
@@911aircooled5 Many thanks
After use I always clean them with a steel brush and then spray it with WD-40, sharp them 4 to 8 times a year. Anyway great video, keep up the great work! 🇳🇱
cheer mate.
ideally you want a lubricant spray, wd40 isn't a lubricant it removes any lubricant if anything.
@@GregsMowing it removes resins that build up in between the blades from all the cutter materials.
Excellent
Thanks
I took mine apart, cleaned it and regreased it. It moves slowly but moves. I thought I put in too much grease but see it was about how much you added. I went back and removed a lot of the grease I added in the gear box prior to seeing your video. Should I go back and add more in the port? What else could make it go slowly as I cleaned the blades very well and wd'd them again once reinstalled. Thanks
Assuming the blades aren't too tight. I agree with you and Add a little more grease through the port shouldn't do any harm. It can be difficult to get the grease everywhere it needs to be.
@@MrGardener18 Thanks so much.... will try
