NOTE: This is a critical adjustment. Adjusting the bracket height will change the
direction of strap pull across the forehead and affect the usefulness of the system.
Step 3 (Fig. 3) - Adjusting the angle of forehead strap
pull: Adjust the assembly up or down to achieve a
direction of pull on the forehead that is perpendicular
to the slope of the forehead (Fig.4).

Dynamic Forehead Strap Adjustment
STEP 1 - Putting on the strap: With the client in
the chair, ensure the head support system is cor-
rectly installed (refer to the previous sections on
system installation). Slide the forehead strap into
position (Fig. 1).
STEP 2 - Tensioning the strap: Using the tension adjusters
tighten the strap to the point required to maintain
constant forehead contact but not tight enough to cause
redness from excessive pressure. (Fig. 2)
Warning: The user’s head must be in full contact with
a support pad at the rear during this adjustment. Failure
to do this is extremely dangerous and will allow the strap
to become loose and slip over the user’s eyes or nose.
READ AND UNDERSTAND ALL INSTRUCTIONS AND WARNINGS BEFORE
ADJUSTING THE DFS TO THE USER.
