Notes:
•
Making a mark next to the cam on the bottom of the
spindle will make judging the adjustments much easier.
•
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.
•
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.
Rotation Belt Adjustment
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, 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.
