First Set Up – Assembly Instructions
To optimize the correct performance of your fixture, please follow these simple
assembly instructions, and refer to this manual if you ever need to reattach the
yoke assembly to your fixture.
In some instances, the yoke assembly will be shipped separated from your
fixture. There are several nylon washers that will be used to correctly space the
metal parts from one another. This will also allow the F8 to be adjusted and
tightened with only one lock point on the left or right side of the yoke. Proper
installation of the washers on the pivot points and the lock points are essential
to maintain the correct operation of the fixture.
The lock point (yoke knob) can be mounted on the left or right side of the
instrument, although it is recommended in most common set ups to keep the
lock point on the right side of the fixture (righty tighty). To install the yoke lay the
instrument on top of a protected surface. Layout your components to mimic
the configuration shown in figure 1. The side with the thumbscrew should have
the Serrated # 10/M5 x .36" OD, stainless washer and two of the 1/2" x .75
nylon washers. The side with the knob lock should have one 1/2" x .75 nylon
washer and the two 1⁄4” x .69 nylon washers. First place a 1/2" x .75 nylon
washer around each side of the pivot located on each of the yoke ears (fig 2).
Next, set the yoke orientation to “lean forward.” You will notice that the base of
the yoke has been shaped so when the yoke mount is vertical in a stand or
perpendicular to the ground, the yoke will sit at an angle towards the front of
the light. This is so the fixture can be pointed further down towards your
subject when placed on a stand (fig 3).
Install the center of the yoke and capture each side of the pivot point screws.
You may need to gently stretch the yoke to engage the pivot point screws. Slide
the small serrated stainless washer onto the slotted thumbscrew (fig 4). Note
the slight bend in the washer’s profile. The outer edge should touch the
thumbscrew (convex side), while the center points towards the pivot point
(concave side). Then take the third 1⁄ 2” x .75 nylon washer and install on the
top of the
yoke on the side that will have the thumbscrew. (fig 5). Install the
slotted thumbscrew into the pivot point, being sure to properly capturing the
nylon washer. Tighten the thumbscrew with a coin or other device only finger
tight. (fig 6). Now flip the instrument to the other yoke point. Slide a 1⁄4” x .69
nylon washer under the yoke at the lock point where the threaded hole will
accept the 1⁄4-20 yoke knob. (fig 7). Place the other 1⁄4” x .69 nylon washer
onto the yoke knob and tighten into the threaded hole, being sure to capture
the nylon washer below (fig 8). This completes the proper installation of the
yoke assembly to the F8.
