Stihl HSA86 gearbox lubrication

Picked up a cordless HSA86 a few weeks ago to replace my nicked HS56.   One thing surprises me.................. there's no "plug" to remove for lubricating the gearbox. In fact they suggest taking it to a Stihl dealer every 50 hours to have the lubrication attended to. On this basis, a lot of "professional" users would be taking the tool down to the dealers every couple of weeks! Is this a ploy to give a bit of extra income to Stihl dealers I wonder:)

Anyway, removed the bottom plastic cover to reveal the gears etc which I then coated with a suitable lubricant.............. replaced the cover.......... all done in 5 minutes so don't let them con you into thinking it's difficult:)

    i bought a kombi strimmer head for my 90 power unit and thats not got a plug to refill grease they said they taken them out of all the strimmer gearboxs

    Recent Stihl strimmer heads have bog standard sealed bearings in. No way to get the grease into them unless you pull the bearing out and pop off the seals. To be fair, they work- no failures in six years with my FS460s.

    Hedgecutter heads don't last long without grease though. Are the electric Stihl ones metal gears? Many electric tools have plastic gears which are self lubricating.

    • The gears are all metal.  I'm surprised the strimmer heads don't require greasing........ I imagined.......... obviously wrongly............ the the grease was primarily there to lubricate the gears

        There's still grease in it it's just a sealed unit

    I picked up a Kombi pick tines attachment recently. No greasing required, its a sealed unit. And this thing does some hard graft!  A bit worrying as I grease nearly all my gear regularly and the grease goes somewhere! This affects all of us in this game so we'll see how this development goes.

    I had the exact same thought and when I questioned the guy in the shop he said they are a sealed unit so don't need a grease port but this doesn't seem right to me. I will be regressing my own like you.
