To pressurize the pedestal using the Vinten portable pump, proceed as follows:
Fully collapse the moving column
(5)
and apply the safety catch
(24)
.
Set the control valve
(26)
to the WORK position (refer to
Setting the control valve
on page
16 for more detail).
Rotate the steering ring
(3)
so that the pressure gauge is visible through the viewing window
(2)
.
On the pump
(Fig 4)
, fold down both the feet
(P.3)
.
Depress the handle release button
(P.5)
and move the handle
(P.1)
to the horizontal posi-
tion, where it will lock.
Pull the hose
(P.4)
out of its stowage
(P.2)
. Connect the hose to the pedestal charging
valve.
Position the pump between the legs, standing with both feet on the fold-down feet
(P.3)
.
Grip the handle
(P.1)
with both hands and, using full steady strokes, pressurize the pedestal
to the required pressure. Do not exceed the maximum working pressure, indicated by the
leading edge of the red sector on the gauge
(2)
.
Disconnect the hose
(P.4)
from the pedestal charging valve, but do not refit the Schrader
valve cap at this stage. Fit the hose in its stowage
(P.2)
.
Push the pump plunger fully down, depress the handle release button
(P.5)
and move the
handle
(P.1)
to the vertical position, where it will lock the pump plunger in the closed posi-
tion.
Fold up both the feet
(P.3)
.
Pressurizing from an external pressure source
A pressure reducing valve must be fitted between the gas cylinder and the outlet connection of
the hose. The maximum pressure on the outlet side of the reducing valve must not exceed 9.6 bar
(139 psi).
To pressurize the pedestal from an external pressure source, proceed as follows:
Fully collapse the moving column
(5)
and apply the safety catch
(24)
.
Set the control valve
(26)
to the WORK position (refer to
Setting the control valve
on page
16 for more detail).
Rotate the steering ring
(3)
so that the pressure gauge is visible through the window
(2)
.
NOTE:
Do not exceed 3.5 bar (50 psi) if the pan and tilt head has yet to be fitted. For
further information refer to
Fitting and balancing the load
on page 22.
WARNING! This pedestal must be pressurized only with clean, dry air or
nitrogen.
