Using the pedestal

Height adjustment
The column has an on-shot stroke of 54 cm (21.3 in.) and the load can be moved over this distance, in
perfect balance, by raising and lowering the steering ring (3).
Column movement can be damped as required, by setting the drag control knob (6) located at the top of
the fixed column (21). Turn the knob (6) clockwise to increase the drag setting, and counter-clockwise to
decease it.
If fixed height operation is required, turn the knob fully clockwise to lock the moving column in position.
Brakes
The skid is fitted with a brake on each wheel. The brakes are applied by pressing down on the lever (15)
situated above the wheel and released by pressing down on the centre 'pop-up' lever which is raised when
the brake is on.
Cable guards
The cable guards (10) fitted to the studio version are height-adjustable and should be set as required. Ad-
justment is carried out by slackening the knobs (9), setting the cable guards at the required height and re-
tightening the knobs.
Cable clamp
A cable clamp (18) is provided on the fixed leg of the skid.
Crab steering
Directional control of the pedestal is achieved by rotating the steering ring (3) mounted at the top of the
column. This rotates all three aligned wheels simultaneously, providing crab steering.
The steering system is geared so that the skid wheels turn by the same amount as the steering ring. This
ensures, for example, that turning the steering ring by 90q will also cause the pedestal to change direction
by 90q
The steering ring is fitted with a movable indicator (4) which can be used to mark the straight-ahead position
of the ring and thus provide a reference point.

Transportation and storage

WARNING!
22
Local, national or international regulations may apply to the transport
and storage of pressurized pedestals.
The control valve (26) MUST be set to the WORK position when degas-
sing the pedestal, or only the pump volume will be vented and the tank
volume will remain.
Reducing the pedestal pressure below 3.5 bar (50 psi) will cause the
remaining pressure to leak.
