1. Set the light bar to the preferred work angle.
a. Pull the park pin (A, Figure 14) and rotate 90° to
unlock the light bar.
b. Rotate the light bar to the preferred work angle.
c. If the light bar rotates loosely or does not remain in
the preferred work position:
• Remove the cap plug from the center of the light
bar.
• Tighten the pivot nut until desired resistance is
achieved.
• Replace the cap plug.
2. Set the tower arms to the preferred work angle.
a. Loosen the adjustment nut (B, Figure 14) on each
tower arm.
Note: Six-light models also feature a park pin similar to the
light bar. Pull and rotate 90° to retract.
b. Rotate each tower arm to the preferred work angle.
c. Tighten the adjustment nuts.
Note: On six-light models, lock each tower arm with the park
pin.
3. Set each individual light fixture to the preferred work
angle.
• Yoke center pivot (C, Figure 14) - adjusts the
horizontal angle of each individual light fixture. Grasp
the sides of the yoke to adjust.
• Fixture pivots (D, Figure 14) - adjust the vertical angle
of each individual light fixture. Move the light fixture
up or down to adjust.
