Replace - Request a spare cog from
your service agent.

drives the cog.
Note:
Under no
circumstances should you apply CRC or
a light oil to the potentiometer. It is a
dry bearing and any lubricant will
render the potentiometer useless).
Send the plate meter to your service
agent for repair.
Check the metal shaft is coming right
back into the base of the tube. Ensure
there is no grass or soil build-up
preventing it from doing so. Also check
the washer at the bottom of the shaft is
not catching on the bottom of the
plate.
Clean the plate meter.
This means that the plate meter does not know where the bottom is - therefore
does not record the reading.
