Hi everybody,

I just became the owner of an AP900GTO of 1999 fitted with CP3 V1 chip and a Keypad.
What is the procedure to perform a re-greasing of the motor box because the grease seems to be old (there is dried deposit)?
Is-it also necessary to check and re-greasing the RA and DEC axis, is there a procedure to do this?

Is there a list of possible upgrade of the AP900GTO version to the latest one (CP3 to CP4, V1 to V2, new motor box...)?

Thanks for your feedback,
