[. . . ] The clamshell rotator design utilizes 98 7/16-inch dual-stacked circumferential ball bearings to distribute load over the full diameter of the housing. This design minimizes stress and wear, and practically eliminates the possibility of destructive water entry: there is no shaft hole in the top of the housing. Instead of the usual AC motor drive used in older rotator designs, the G-800SA and G-1000SA use a DC motor, obviating the need for a large starting capacitor with its potential for failure exposed to outside temperature variations. The factory-lubricated rotator unit is housed in melamine resin-coated die-cast aluminum, intended to provide maintenance-free operation under all climatic conditions. [. . . ] Confirm that all solder joints are firm and cleanly made, as this part of the cable will be difficult to access once the rotator is installed on top of the tower. Do not slide the shell onto the connector at this time. Crimp the supplied pin contacts onto the wires on the opposite end of the cable, per the illustration below. Referring to your notes of the wire color at each pin of the round (rotator end) connector, insert the pins into the rectangular plug at the opposite (controller) end of the cable. Be sure that each wire from the round connector is routed to the corresponding pin number in the rectangular connector (i. e. Temporarily connect the round plug to the rotator, and the rectangular plug to the controller. Make sure that the POWER switch on the controller is set to "OFF, " then plug the controller's AC cable into your station's AC outlet. Then, grasp the needle at its center and pull it straight off, replace the needle to 180° (straight down), and replace the bezel. Just above the round connector jack on the rotator unit, you will observe two raised calibration marks (one each on the "rotating" bell and "fixed" base of the rotator). These two marks should be directly aligned with each other. If not, place a small piece of masking tape on the rotating bell and the fixed base of the rotator unit, and make a calibration mark will be used to verify the amount of rotation in the next step. Press the RIGHT (rotation) side of the seesaw switch, and continue rotating to the right until the calibration marks (from step 7) are again precisely aligned. Now check the indicator needle, which should also have rotated fully 360° so as to be pointing exactly to 180°. If the indicator needle is not pointing exactly to 180°, go to the rear panel of the controller, and use a small screwdriver to adjust the FULL SCALE ADJ potentiometer (see the drawing to the right) so that the indicator needle points exactly to 180°. Press the RIGHT switch again, and continue rotation to the right. You should observe the OVERLAP LED becoming illuminated as rotation passes the 180° point. If the OVERLAP LED does not light up at the 180° position, the OVERLAP LED ADJ potentiometer (on the rear panel of the controller) may be used to align the illumination threshold to the 180° point. Check to verify that rotation automatically stops at approximately 270° (West; representing a total rotation range of 450° from the original starting point). Press the LEFT and RIGHT (rotation) switches a few more times, verifying that rotation appears to be normal. If so, press the LEFT or RIGHT (rotation) switch to set the rotator to 270° (West). Set the SELECT SWITCH on the rear panel to the left (OPERATION MODE) position, and turn the POWER switch "OFF. " This completes the ground-based testing of the rotator and controller. 8. 9. 10. 11. 12. 13.

This is particularly useful when you need to have south at the top of the dial (or east or west) instead of north. [. . . ] The Yaesu GS-050 and GS-065 include guying "ears" which allow attachment of guy cables. As installing a guying system may cause the centerlines of the guy bearing and the rotator to become mis-aligned, be certain to check the roof tower attachment and guy cable alignment to ensure that the mast is straight.
