Excellent post, very useful to FS56 and FS70 users!!

Thank You for the video. After 20 years (yes... twenty-btw still works) I bought a second one FS 55, I was shocked that the greasing point is missing. Seller told me it is maintenance free.....!!! The old one I greased 1-2 x per year, never NEVER failed the gearbox. Great idea the greasing adapter, like it.

Thanks for posting this, I really appreciate it. 👍

Good idea. Just bought one and I knew the gearbox needed greasing but I love the useage of the nozzle to reach the correct point. Thank ou and I wish you well.

Always learning and thank you so much for your video my friend, helped me a lot 👍🌿

Brilliant! Kudos to you for thinking to post this! No Kudos to Stihl and Echo that decided they could show they don’t really give a damn about making products that are easy to maintain😡

Just what I was looking for, very useful info, thank you!

Thanks, i have fs 55, the video is very useful !

Thank you for this - mine keeps welding the line in the head so hopefully a bit of grease will help stop getting it so hot

Exactly the video I was looking for. Thanx!

I just put a grease fitting in the hose of the grease gun and use that to get grease into the slot

Thanks very much for sharing this tip. Regards Simon / Adelaide / Australia

Excellent tip thank you for posting 👍👍

I have a video on doing this exact thing! Great job brother🤘🤘

thank you

Köszönöm!!

thank you very much mk15handyman very helpfull indeed thank you

I wonder if you can put a 1/4" zerk onto the head for easy greasing.

Thanks for the maintenance tip. The Stihl dealer says these are sealed & non-serviceable. Guess is they want to sell more trimmers. Even a sealed unit that doesn't leak will break- grease is subject to heat & shearing ( parts rubbing on each other) causes the grease to dry out. If the dealer had told me before purchase the gear unit was sealed, I would have bought one that wasn't sealed. Dealer will also tell you that replacing the gears cost nearly what the machine cost to begin with.

Ta ,thanks good tip.

I am using small 2.5cc syringe and fill 2.5cc to 3cc is enought but greasing 2 times a season. I will do today. Cos my main brush cutter sub one is bike gandle shindaiwa mountain use professional.

How did you take out that screw on the bolt after taking off the cover? I feel like I'm gonna brake the wrench it's on solid

I come to a halt at the 1.33 mark. The screw/bolt will not screw out. The nearest allen wrench in either metric or us either spins or gets a grip that can strip the female part of the screw out. I notice that you have a whacking big bolt. Did that mean you stripped the allen wrench and replaced it?

Do you think it's feasible to add a grease zerk fitting where its missing there grease access point?

Do that with your fc91 edger also

Where did you get the tip

I never know how much grease to squirt in there

What type of gear box is fa 55 called😢
