I have this trimmer head - AEG Bump Feed Line Trimmer Head - Bunnings New Zealand. But there are no instructions.
I wish to replace the head on the AEG 18V 33cm 4.0Ah Brushless Line Trimmer Force Kit - Bunnings New Zealand.
I have the AEG Metal Pin to remove the trimmer head.
I can see on the head where the pin is to go. I push the metal pin into the hole for the pin, but nothing happens. I can push and push the pin in (even use a block of wood at the end of the pin to save my hand), although I believe it doesn't it move a millimetre.
Hi @alkifaf,
The pin's only job is to lock the drive shaft in position. This stops it from spinning freely when trying to undo the head. So, you are inserting it correctly, but now you need to unscrew the head off the shaft as per the image below. When looking at it, the head needs to be turned clockwise to undo. Installation is the reverse.
Please let me know how you go.

As per your words on how to do this - I have succeeded.
I feel silly, but a little mad that AEG provide no words (and I had seen this diagram). I fully expected the pin to push in a little, so that there is some feedback that the head was ready to be unscrewed.
Nevertheless, your help has been invaluable.
That's fantastic to hear, @alkifaf; I'm glad you got it sorted.
It's only that I am familiar with this type of head removal, not that the images particularly helped me. I'll pass the feedback to AEG that a bit more information would help customers.
Hi,
I'm replacing the head on the AEG 18V 33cm 4.0Ah Brushless Line Trimmer.
I have the brand new bump head but cannot work out how to remove the remainder of the body. I also cannot locate the pin/tool. Can I use something like a hex key?
TIA.
Side note - the AEG manual is useless!!
Hello @jlidds
Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about your AEG line trimmer.
As per Mitchell's suggestion. The pin's only job is to lock the drive shaft in position. This stops it from spinning freely when trying to undo the head. So, you are inserting it correctly, but now you need to unscrew the head off the shaft as per the image below. When looking at it, the head needs to be turned clockwise to undo. Installation is the reverse.
Your objective is to look for that small access hole on the side of the feed head which is technically above it if the trimmer was facing in the correct orientation. I suggest using a long steel pin or https://www.bunnings.com.au/craftright-8-piece-t-handle-hex-key-set_p6060095 . One of the Allen keys should fit the access hole. Slowly push the Allen key into the hole until it stops, start rotating the trimmer head until the Allen key slots into the locking position. This technically stops the trimmer head from rotating, firmly grip the head and turn it clockwise to loosen and anticlockwise tighten as seen in the image below.
I have also included a general video demonstration on how it might be done - Unbelievable Trick To Easily Change Your Trimmer Head! (proceed to 45 second mark to see how its done)
If you need further assistance, please let us know.

Superb. This is exactly what I needed. Thanks, Eric!
