Series 4A Set Up:
Step 1â€“ Adjust
the shoulder width adjustment
You will want to measure
the width of your neck (diag. 1-A). The Series 4A has a neck width that ranges
from 4.75 to 7.75 inches. Upon establishing that measurement, you will want to
adjust your shoulder adjustment (diag. 1-B) to 1 inch wider than your neck
measurement. Remove 4 screws and binary posts and set to correct position. If
you will be adjusting wider than the setting out of the box, you may need to
loosen the strap, video instructions
Step 2- Adjust
the UPPER ARM Angle
It is recommended that you
adjust this in your race seat to get the best angle for your individual needs.
There are two screws on each side (diag. 2-A ). Screw #1 is the only screw that
needs to be removed to adjust angle. Screw #2 does not need to be removed and
it has thread lock on it from mfg. Remove Screw #1, and adjust the arm angle so
that fits snug against body, but does not protrude into your body. Adjust both
sides to same angle.
Upon completion of steps
1-2, once you are 100% happy with the fit of your
restraint, we recommend that at this time your remove all screws one at a time
(except screw #2 in step 2) and secure them with tread lock â€œblueâ€ and tighten
Step 3- Adjust
tethers and strapping
It is recommended that you
evaluate the video here in
regards to adjustment of tethers and strapping. You will want to make sure the
strapping stays in the same configuration throughout the hardware as you receive
it from the mfg. There are two points which you will want to adjust (diag.
4-A). Point #1 should be adjusted to 2.75 inches (70mm) and Point #2 should be
adjusted to approx. 1.75 inches (45mm).
Step 4- Setting
