It uses a flat, toothed belt (like a cambelt) to drive the magnetic
'friction' flywheel and as that gently drifts against the guide /
tension rollers it gives of a sort of rhythmic squeak.

If the traction of the belt is acheived with the teeth (rather than just
friction) you may be able to get away with a little silicone grease.
(Only make sure it is silicone as normal grease will cause your rubber
to perish - and you won't be getting much squeeking after that!)

The sheds will most likely have some, if not a plumbers merchant will -
it's is used on the O rings of push fit waste fittings to make assembly
easy. CPC also do it in handy tubes:-
