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! 🇳🇱

I have the hedge trimmer 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

Brother. Question. how too remove the mounting screw for this head. That keeps the head swivel mounted

[jasonhewlett]

👍. An essential bit of maintenance, my ego trimmers need greasing daily . I have not replaced blades yet, the gearboxes pack in first. 😐

[GregsMowing]

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.

The screws which hold the blades in place down the full length of blades, do these get fully tightened ? Or left with a bit of play to allow blades to move ?

[Tropazio]

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

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.

Can you help....How do you repair a bent tooth on a hedge trimmer? Electric in my case.

🤣 you didn’t remove the main cam follower. You’ll have dirt buried under them. Also it sounded so rough when you hand turned the shaft. Your needle bearings are knackered.
