Load Adjustment
Drifting
If a spring arm supports a load that is greater (or less) than the force of the spring, the spring arm will not stay perfectly
in place because the weight of the load pulls the spring arm downward (or upward).
Adjustment of the spring inside the spring arm will allow the user to fine tune the spring arms ability to support a
load. Load adjustments must also be carried out during regular maintenance.
Risk of Damage to the Spring
The spring arm supplied has a specific spring with a specific load range. Please refer to your product sticker attached
to the arm for your exact load ranges. Not adhering to these load ranges may result in permanent damage to the
spring, causing the arm to drift and prematurely fail. Replacement or service by a technician may be required.
Risk of Pinched Fingers
Fingers can be pinched or cut if inserted into the load adjustment window of the spring arm body. Exercise caution
when making adjustments to components inside the spring arm body. Components inside will move when spring arm
is moved up or down. Do not insert fingers or tools into the load adjustment window when the spring arm is moving.
Installation: Adjustments
In order to carry out load adjustments, observe the
following instructions:
1. Ensure that the main covers of the spring arm have
been removed and the lighthead has been installed
to the spring arm.
Note: While performing a load adjustment, it
is recommended that you compensate for the
removal of the covers by adding an equivalent to a
1 lbs weight (equal to one side cover being hung)
at the end of the spring arm.
2. Locate the load adjustment window [1] in the
spring arm body and the load adjustment nut [2].
(Depending on its first calibration, the spring arm
may have to be moved up or down to bring the nut
into view.)
3. Insert the adjustment tool [3] into one of the holes
on the nut.
