Operation

Unpacking

Unpack the pedestal, ensuring that all transport packing and retaining fixings are removed.

Steering mechanism checks

Rotate the crab/steer knob (25) anticlockwise to select CRAB (x4), and turn the steering ring (29) until ‘crab
mode’ engages. Check that the pedestal ‘crabs’ correctly, freely moving as directed by the steering ring (29)
without any rotation of the pedestal base.

Rotate the crab/steer knob (25) clockwise to select STEER (x1) and turn the steering ring (29) until it locks in
position and ‘steer mode’ engages. Check that the pedestal turns freely, rotated by the locked steering ring
(29).

Pressurizing the pedestal

The Fusion FP-145/FPH-145 pedestal may be pressurized from an external pressure source or by using the
Vinten portable pump (Part No. 3357-3). Trim weights (30) are provided for fine balance.

A correctly pressurized pedestal will balance its payload, allowing movement over the full on-shot stroke of the
moving column with minimum effort, and will maintain its position when the steering ring is released. Balance
can be adjusted by adding or removing trim weights (30) to the weight tray pockets (3), or venting some of the
internal pressure.

Ascertain the payload to be fitted to the pedestal (payload = pan and tilt head, camera, lens and all ancillary
equipment). Referring to the graph (Fig 2), mark the payload on the horizontal axis then strike a vertical line
from the load figure to the balance line. At the intersecting point strike a horizontal line to the vertical axis and
read off the required pressure.

The pedestal pressure must be reduced to a maximum of 7.2 bar (105 psi) before fitting the pan and tilt head
(refer to Fitting the load on page 18 for more detail).

WARNING! 1. Do NOT lift unaided. This product weighs up to 130 kg (286.6 lb).

2. Do NOT lift the pedestal by the steering ring - use the lifting handles (10).

3. Do NOT release the column lock (27) if the pedestal pressure exceeds 7.2
bar (105 psi) without a balancing load installed. Reduce as necessary,
using the Schrader valve cap (1).

CAUTION! Do not reduce pedestal pressure below 3.5 bar (50 psi). This ensures that the elevating

mechanism remains in tension, preventing damage to the pedestal.

WARNING! 1. Do NOT pressurize the pedestal beyond the maximum safe working pres-

sure indicated by the leading edge of the red sector on the gauge.

2. Do NOT adjust the pressure relief valve. Personal injury and pedestal
damage may occur.
