Top stage
10
The top stage of the column has an on-shot stroke of 414 mm (16.3 in.) and the load can be moved
over this distance, in balance, by raising or lowering the steering ring.
11
A clamp
is provided for the top stage. This can be used to hold the top stage in position if fixed-
height operation is required. Turn the clamp lever clockwise to apply the clamp and counter-clockwise to
release it.
Brakes
12
Each of the pedestal wheels is fitted with a foot-operated brake
. The brakes are applied by pressing
down on the lever situated above the wheel and released by pressing on the centre 'pop-up' lever which is
raised when the brake is on.
Adjustment of cable guards
13
fitted to the studio version are height-adjustable and should be set as required.
Adjustment is carried out by slackening the knobs, setting the cable guard at the required height and
re-tightening the knobs.
Pedestal movement
14
The wheels on the studio version of the Vision pedestal have the facility of being locked into the straight
ahead position or of castoring freely. The castor/lock changeover is effected by track lock pins
, located
just above each castor; the pins on the folding skid legs have black knobs and the pin on the fixed leg has a
red knob. Each lock pin is spring loaded to engage in a hole in the castor top plate. Each track lock pin may be
secured in the disengaged position by pulling it up against the spring and turning it through 90°. To engage the
track lock turn the castor to align with the pin and then turn the lock pin so that the cross pin drops into the slot
in the housing. Note that the lock will only engage when the castor is correctly aligned.
15
The castor/lock arrangement provides castor, track and steer modes.
16
For castoring motion, disengage all three track locks
. The pedestal can now be moved freely in any
direction.
17
For tracking motion, engage all three track locks. The pedestal can now track back and forth in a
straight line.
18
For steer motion:
18.1 Position the fixed leg of the skid (the one with the RED knob on the track lock pin) in the intended
direction of travel.
18.2 Engage the black track locks.
18.3 Disengage the red track lock.
WARNING!: To ensure maximum stability, particularly when moving over uneven
ground, reduce pedestal height to a minimum
