4 Adjusting the parts
4-3 Adjusting the raising/lowering balance of the
balance arm
1. Detach the upper cover and lower cover of the
balance arm
(See Step 1,2
in “Adjusting the upper limit position of the
balance arm” [page 50].)
2. Adjust the raising/lowering balance of the balance
arm by turning the adjustment nut nearer the light
head, using the attached adjustment rod.
When adjusting the balance arm with the jig (optional),
attach the jig at the position shown in the figure below.
In case of adjusting the balance arm without a jig, adjust the
balance arm to make it tilt slightly upward so that the arm will
balance horizontally when equipped with the upper and lower
covers. If the arm still doesn't balance, detach the upper and
lower covers, then readjust the arm again.
3. Reattach the upper cover and lower cover of the
balance arm
(See Step 5,6 in “Adjusting the upper limit position of the
balance arm” [page 51].)
When the arm is raised excessively
-> Turn the nut toward the − side
When the arm is lowered excessively
-> Turn the nut toward the + side
