Pressurizing the pedestal using a portable
pump
!
WARNING! Do not pressurize the pedestal beyond the
maximum safe working pressure indicated by the leading
edge of the red sector on the gauge. The pedestal is
tted with a pressure relief valve as a safeguard against
over-pressurization. Do not attempt to adjust the
pressure relief valve.
!
WARNING! A pressurized pedestal will rise rapidly when
safety catch is released. Do not release safety catch
when pedestal is pressurized and balancing load is not
installed. Always restrain the pedestal by hand pressure
on the steering ring when the safety catch is released.
To pressurize the pedestal using the Vinten portable *pump, proceed
as follows:
1. Set the control valve (2) to the WORK position.
2. Fully depress the moving column and engage the safety catch (7).
3. Attach the intended payload, see Fitting and balancing the load
on page 15.
4. Turn the Steering ring so the pressure gauge (3) can be seen
through the weight tray.
5. Connect the pump adaptor (5) to the pedestal charging valve (23)
by turning clockwise until nger tight.
6. Connect the pump hose (6) to the pump adaptor (5) and ip the
lever upwards to secure.
7. Position the pump between the legs, standing with both feet on the
pump feet.
8. Grip the pump handle 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 (3).
9. Disconnect the hose from the pedestal charging valve, but do not
ret the Schrader valve cap at this stage. Push the pump plunger
fully down, and store.

Note! In the event that the pedestal air pressure has
dropped to 0 psi, proceed as follows:
Follow steps 3 to 4. The pump features a shock
function (Lever in Position A), this allows the pump to
store pressure with every stroke up to approximately
75psi. When this pressure is achieved turn the lever to
position B. This will force the O-ring in the pedestal to
seal. Resume from step 5.
