I can't remove the blade from my Bamix hand blender

Try to gently wiggle it off with needle nosed pliers.

My Bamix stopped working--no shaft movement and loud motor noise (think disuse caused motor lubricant to thicken). Propped it upside down and put drops of quality machine oil at seam where narrow blade shaft enters larger shaft (in center of curved guard). Probably not necessary, but added a few drops where large shaft enters handle. Oil slowly seeps in. Attached a blade to manually turn for oil distribution. Did this periodically over several hrs. Turned on low speed and it gradually returned to full speed capacity.

They get gently wiggled off. The notch is so that they click in and don't fall off while they are performing.

Amazon. All new blades still fit.

It seems you can no longer buy the MegaMixa HA-3058 however Bamix sell a similar product - in fact apart from a couple of aesthetic modifications it seems to be the same machine....

They sell many accessories and you can get blades. Check:
www.bamix.com
www.bamix-blender.co.uk

I have both machines and the blades are identical and inter-changeable between models.

Good luck, love my Bamix!

Excerpt from: http://www.bamix-usa.com/

It can happen that the attachments fall off the shaft as they have in time become loose. In this case simply press the spring blades lightly together with a pair of pliers

It says in the manual to soak it in very hot water for 10-20 minutes, then try again. This should free trapped food from the shaft

The blades pull straight off the shaft. If you look closely you will see a small notch on the blade that fits a tab on the shaft. This keeps the blade turning at the same speed as the shaft.

Anyway, pulling straight down on the blade should get it off. You might try boiling the tip in water to soften whatever gunk is holding it on. Be careful you don't burn your fingers when trying to pull off the blade after boiling it.
