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.
