6. Adjustment of Arm Balance to Eliminate Drift
The jib arm on your DARAY light will have been balanced during manufacture, however over
time you may need to occasionally rebalance the arm, particularly if the arm ‘drifts’ into a
lower position when you move the head.
Note: Before adjusting the arm
tension, ensure the head and
handle are both attached.
Step 1
Push the primary arm up to its
highest position, this makes it
easier to adjust the tension.
Step 2
Locate the capstan (see image
circled right). This is accessible
through a small gap in the
underside of the primary arm,
through which you will see a nut
with two small holes in each side.
Insert a small implement (e.g. hex
wrench 2mm AF) into one of the holes
in the capstan located at the top of the
jib arm (can be seen when standing underneath
the arm). You will see stickers labelled 1 and 2 on either side of the capstan opening.
Step 3
TIP: Grip the hex wrench as close as you can to the base to prevent it from bending.
- If the arm is drifting downwards: Turn the capstan in the direction of label 2 until
desired balance is obtained.
- If the arm is drifting upwards: Turn the capstan in the direction of label 1 until
desired balance is obtained.
You should be able to set the head in the required position with no further movement once
you let go of the head.
To assist in making this adjustment, it may be necessary to remove the arm joint cover (see
section 6.4 – page 23). This provides better access to the slot through which the capstan nut is
adjusted.
Note: When re-assembling the arm joint cover, ensure that the moving cover is correctly
positioned with the ‘T’ notation on the component at the ‘Top’.
