Installation
Unpacking
Unpack the pedestal ensuring that all transport packing and retaining fixings are removed,
including the Velcro strap (part no. 3320-268) securing the column lock.
Steering mechanism checks
1. Rotate the CRAB/STEER knob [17] anti-clockwise to select CRAB (x4 wheels) and
turn the steering ring [19], until CRAB mode engages. Check that the pedestal
“crabs” correctly, freely moving as directed by the steering ring without any rotation
of the pedestal base.
2. Rotate the CRAB/STEER knob [17] clockwise to select STEER (x1 wheel) and turn
the steering ring [19], until it locks in position and STEER mode engages. Check that
the pedestal turns freely, rotated by the locked steering ring.
Pressurising the pedestal
The pedestal or height drive may be pressurised from an external pressure source (see page 20)
or by using a portable pump (see page 21). Six trim weights are provided for compensation of
pressure variation.
A correctly pressurised pedestal will balance its payload—allowing movement over the full on-
shot stroke of the moving column with minimum effort—and maintain its position when the
steering ring is released. The balance can be adjusted by adding/removing trim weights to/from
the weight tray pockets [5] or by venting some of the internal pressure.
WARNING!
1. Heavy – DO NOT lift the pedestal 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 on top of the pedestal base.
3. DO NOT release the column lock, if the pedestal pressure
exceeds 7.2 bar (105 psi) without a balancing load installed.
Reduce pressure as necessary using the Schrader valve cap.
CAUTION! This pedestal must be pressurised with nitrogen or clean, dry air only to
prevent internal corrosion.
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.
