Maintenance
Cleaning
The KNIGHT
2
is constructed with corrosion resistant aluminum and stainless steel fasteners. To further
enhance corrosion resistance all exposed surfaces receive a powder coated paint finish. To ensure years
of trouble free service periodically clean all external surfaces with a mild detergent solution and a gentle
spray of water. DO NOT USE A HIGH-PRESSURE WASHER , which will force water into sensitive
electric circuitry.
Lamp lenses may be cleaned with any commercially available glass cleaner.
Upper and lower stage actuators are sealed units and do not require adjustment or lubrication. The
actuators have slip-clutches to compensate for minor stroke tolerances at the limits of its travel. The
actuator may produce a ratcheting sound at each end of the stroke which is normal. The actuators should
not be made to ratchet excessively, this can lead to premature actuator clutch failure.
All pivot points on the KNIGHT
2
are self-lubricating thermal polymer. Periodic cleaning with a
moisture displacing cleaner and soft bristle brush, without disassembly, to remove accumulated dirt and
debris will minimize wear.
Center Switch Adjustment
WATCH THE VIDEO AT WWW.COMMANDLIGHT.COM/TECHNICAL-VIDEOS/
Caution: For best results, angle of vehicle should be less than 10 degrees.
1. Raise lower section high enough to comfortably work on, and above the set safety limit
(i.e. Lights will turn on), then raise lamp tree to a 45 degree angle.
2. Visually verify the centering cam on the rotation spindle is contacting the roller of the center
switch arm.
3. Ensure that when the point of the centering cam is aligned with the roller of the center switch
arm, there is some play in the center switch arm. Without this play, the switch could be crushed or
damaged during rotation.
4. Rotate off center, then press the auto park button and let light tower proceed through sequence until
the lamp tree is a couple inches above the nested position, hit emergency stop.
5. Visually determine which side the lamp tree will be hitting the lift arm, then lower lamp tree
completely using the motion switch on the handheld controller.
6. Raise lower section above safety limit and to comfortable working height.
7. Make reference marks with a permanent marker on both sides of the cam.
8. Loosen screw on center switch cam slightly.
9. Tap centering cam toward the side that the lamp tree is hitting the lift arm.
10. Fully tighten the screw holding the center switch cam.
11. Raise lamp tree to a 45 degree angle, rotate off center.
12. Repeat steps 4-9 until satisfied with centering of the lamp tree.
13. If it looks like center is now adjusted properly, raise lamp tree to a 45 degree angle, and lower stage
all the way up, press autopark and let it go through the entire sequence.
14. If it is still hitting off center, repeat previous steps.
15. If problems adjusting center still persist you may need to adjust the center switch bracket, or call
