1100GTO, slight free play in RA axis only. Is a backstop adjustment needed?


I've had my 1100 for a few months and it has performed well.  However I noticed from day 1 a small amount of free movement in the RA axis while the Dec axis has none.  The amount of play in the RA axis is between 1 and 2 mm of movement at the tip of the counterweight shaft.  

Is this amount of play normal/correct, or should I adjust the RA gearbox backstop as described on page 34 fo the owners manual?
