I've run mine from end-to-end repeatedly without problems. I would suspect the duty cycle is also related to the amount of load (antenna size/weight, and wind) on it, so YMMV.
Looking at the schematic shows the "other" two pots on the back panel have the same function as the "Full Scale Adj", but instead of driving a meter, they send the scaled voltage out to the 8-pin DIN connector on the rear panel, where it is normally goes to the IF232 unit for position feedback.
I don't have a problem with the terminal strips on the back. I made 3' 'pigtails' with spade lugs on them, dressed them neatly into the nylon cable clamps, and then put some Molex connectors on them. I have the  mating Molex connectors on my rotor cables in the shack, and this allows me to unplug the control box and move it around without unscrewing all the terminals.
Total cost about 5 bucks....

I just finished up the cables for the rotor
And been reading thru the manual .. ( lacking a bit )

It says 5 minutes intermittent service and something
About 15 minutes rest.  I assume then , that it means
5 minutes on , 15 minutes off.  

Doesn't seem like it takes a whole 5 minutes to run the whole
Rotation , but wanted to know if its ok to go from one end of
The rotation to the other without stopping? Wanted to ask if that seems

For setup I ran the azimuth and elevation to CCW to the stop to make sure
It stopped correctly and the meter indicated correctly, then went the other
way to full meter deflection, to the
Stop and adjusted the Full Scale adjustment for full scale.  That's all
there is
To it?  Whats the voltage output adjustments for?

One more thing .. On a side note.. I thought it was cheesey to have "radio
Type terminal strips on a 600.00 rotor to connect the rotor cable too ... 
Why not have a couple connectors there? Even my old Wilson WR-500 had a
connector. Lol

I assume even with 2 small yagis on this rotor, I will now have to guy the
mast due to the
Added weight of the rotor on the mast ?
( better safe then sorry LOL )

Thanks everyone ..
