4.1.3. With the 1/2" [13mm] socket wrench on the Adjuster, carefully unlock the arm. Turn the Adjuster counterclockwise
(CCW) to increase counterbalance force, or clockwise (CW) to decrease counterbalance force. Counterbalance is
correctly adjusted when the mounted instrument can be moved up or down with minimal force and does not rise or fall
after releasing the Arm.

4.2 Adjusting Height of the Mounted Instrument
WARNING
• Do not attempt to adjust height without device(s) mounted on Arm.
• Stand to the side of the VHM Arm and mounted instrument and use caution when disengaging the
Height Locking Knob. The total mounted load may have changed due to the addition or removal of
equipment (other than primary instrument) while the Height Locking Knob was engaged. A change in
the total load can cause a sudden downward or upward movement of the Arm when the Height Locking
Knob is disengaged.
4.2.1. Grasp mounted instrument and move to desired height. When Arm is counterbalanced correctly (sec 4.1), it will
maintain position when adjusted to a new height.
Note: Disengagement/ re-engagement of the Height Locking Knob is necessary during vertical adjustment of
mounted instrument (see WARNING above).
