Head/Yoke Adjustment; Figure 42: Head/Yoke Adjustment - Nuvo VISTOR Installation & Service Manual

The head/yoke has been pre-adjusted by the factory. Should further adjustment be
necessary, utilize the following procedure.
• Find the yoke cap for your specific light as shown in a heavy circle below (see figure 42).
• Cradle the sides of the cap with your thumb and index finger. Squeeze and then pull out the
yoke cap to expose the nut, or gently pry off with a flat bladed screwdriver.
• Use a wrench or pliers to tighten the nut as shown. Add thread-locking liquid (e.g. Loctite)
around the inside of the nut if the nut continues to loosen during yoke rotation.
NOTE: Do not over tighten the nut. Doing so could result in equipment damage.
• Push the yoke cap back into its original position.
