Vinten FHR-35 User Manual page 21

If the camera cradle tilts backwards (points upward) then the camera
must be moved towards the front of the head (fore).
3.
Reposition the camera as required on the camera cradle and
secure in position. The horizontal balance is correct when the
camera cradle comes to rest in a horizontal position.
4.
Tighten the bolts securing the camera to the cradle and recheck
the horizontal balance. Readjust if necessary.
Note: If the camera has to be moved too far fore or aft to balance
the head, you can remove the camera cradle base plate and
refit it, using two screws, 50 mm further in the required
direction.

CAUTION! Risk of damage to equipment. Be prepared to
prevent the camera and camera cradle from falling away
suddenly.
1.
Tilt the camera approximately 30° upward and release it.
If the camera stays in the same position when released, the
payload is properly balanced with the C of G on the tilt axis.
If the camera continues to move upwards after releasing the
camera cradle, the payload is mounted too high—lower the
camera cradle.
