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.
Rotation Belt Adjustment / Tightening
WATCH THE VIDEO AT WWW.COMMANDLIGHT.COM/TECHNICAL-VIDEOS/
1. Raise lamp tree 45º and rotate away from
motor to access rotation motor screws.
2. Remove the (4) screws from the front
midplate cover.
3. Loosen, but do not remove, screws that
retain rotation motor.
4. Using a 1/2" wrench, loosen the jam nut on
the belt tensioner bolt. Using a 3/16" Allen
socket tighten the tensioner bolt to 20 inch
pounds. Tighten the jam nut to lock bolt
in place. 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.
5. Replace the cover 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.
