Notes:
• Making a mark next to the cam on the
bottom of the spindle will make judging the
adjustments much easier.
• Having the lamp tree at either extreme of fully up or down, will affect the degree of
centering. Setting center while the lamp tree at a 45 degree angle produces the best results.
If problems persist, please call Command Light at 1-800-797-7974.

1. Raise lamp tree to permit easy access.
2. Remove the (6) screws from the 2-piece midplate cover.
3. Remove the (4) screws that retains the midplate surround cover. Rotate the cover up and
away from the main lift arm, around the pivot point.
4. Lower lamp tree fully and rotate away from motor to access rotation motor screws.
5. Loosen, but do not remove, screws that retain rotation motor.
6. Make sure both pulleys are parallel and in alignment with each other. To adjust any
misalignment, loosen the (2) set screws securing the small drive pulley to motor shaft.
Adjust as required and tighten set screws.
7. Belt should fit snugly, neither too loose nor too tight. Avoid any preload, which can cause
premature failure.
8. Using a suitable pry bar and a wood or polymer block/spacer, apply gentle pressure
between rotation motor case and sheet metal motor mount. Use caution to not over tighten
drive belt. Rotate lamp tree 180 degrees to verify that belt is not too tight. If belt is too
tight, rotation motor noise level will rise noticeably.
9. Replace all covers before returning light tower to active service.
• With the centering cam slightly loose,
it may be easier to adjust its position by
tapping on its edge with the assistance of
a socket driver rather than attempting to
move by hand.
