Pressurizing manually
To pressurize the pedestal manually, proceed as follows:
Set the control valve (2) to the PUMP position.
Ensure that the bottom stage (6) is fully lowered and the red bottom clamp (19) is applied.
Push down on the steering ring (21) against any residual pressure and release the safety
catch (7).
Move the slide to the OFF position (O).
Using the steering ring (21), raise the top stage until fully extended. Commence pumping
by lowering and raising the top stage over the upper half of its travel. When the pressure
gauge (3) begins to register, pump the top stage over its full stroke. Stop pumping when
maximum working pressure is reached (indicated by the lower edge of the red sector on the
gauge) during the pumping stroke.
Set the control valve (2) to the INTERMEDIATE position and allow the top stage to rise fully.
Set the control valve (2) to the WORK position.
Install the camera mount and payload and balance the load as described below.
Pressurizing from an external source
To pressurize the pedestal using an external source, proceed as follows:
Set the control valve (2) to the WORK position.
Push down on the steering ring (21) against any residual pressure and release the safety
catch (7).
Move the slide to the OFF position (O).
Remove the Schrader valve cap (23) and connect the charging line from the pressure
source.
WARNING! Bottom stage elevation is assisted by a gas strut. The bottom
stage will rise rapidly if released with no payload fitted. Do not
lean over the pedestal when releasing the safety catch and/or
the bottom clamp
WARNING! A pressurized pedestal will rise rapidly if the control valve is set
to WORK. Do not move the control valve directly from PUMP to
WORK
WARNING! A pressurized pedestal will rise rapidly when safety catch is
released. Do not release safety catch when pedestal is pressu-
rized and balancing load is not installed. Always restrain the
pedestal by hand pressure on the steering ring when the safety
catch is released
