Operating Instructions

3 Counterbalance Control

The counterbalance system was designed to neutralise the

effect of the camera weight when it is tilted. The Skyline 70

Fluid Head offers an 8 position counterbalance system which

can be operated via the COUNTERBALANCE SELECTOR (fig. 2).

The COUNTERBALANCE SELECTOR must be operated when the

SLIDING PLATFORM is in a horizontal position. After changing

the Counterbalance setting it may be necessary to tilt the camera

back and forth to ensure that the CB spring has engaged. The

camera must be held securely while changing the Counterbalance

setting.

3.1 For safety ensure that Counterbalance position 8 is selected.

3.2 Hold the camera and release the TILT LOCK, then gently

tilt the camera from a horizontal position forward then

backward and observe its response. If the Camera 'Springs

Back' to the horizontal position then a lower Counterbalance

setting is required, select Counterbalance position 7 and

recheck, select lower setting again if necessary. Correct

counterbalance setting has been achieved when minimum

effort is required to move the camera over the entire tilt

range.

TIP Fine tuning can be achieved by adjusting the SLIDING

PLATFORM – see step 2.6.
