Using the column lock
The column lock [6] locks the column in the fully depressed position.
• To release the column lock, push down on the steering ring [19] against residual
pressure and rotate the column lock catch [6] downward into the OFF position.
• To engage the column lock, rotate the column lock catch [6] upward into the vertical
position. Fully depress the column [32] until the lock engages.
Cable clamp
A cable clamp is provided on the base [15] and the power box [23] (at the South side of the
pedestal, see Fig. 2).
WARNING!
1. DO NOT release the column lock, if the pedestal pressure
exceeds 7.2 bar (105 psi) without a balancing load installed.
Reduce as necessary using the Schrader valve cap.
2. DO NOT lean over the pedestal. An over-pressurised pedestal
may rise rapidly when the column lock is released, causing
personal injury.
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.
