Skid clamp adjustment
To adjust the skid clamp:
The skid clamp
is applied or released by turning the handle clockwise or counter-clock-
wise. The handle has a pull-off/push-on ratchet adjustment. To take up wear, pull the han-
dle away from the spindle, rotate counter-clockwise and release.
Repeat the above procedure, as necessary, until the clamp locks when applied but allows
free movement when released.
Elimination of radial and side play in the moving column.
If excessive radial or side play is apparent in the moving column, refer to the appropriate section
in the Maintenance Manual. This adjustment should be carried out by a competent person.
Routine maintenance
At three-yearly intervals, the three steel wire ropes in the column elevation mechanism should be
replaced.
This procedure should be carried out by a competent person in accordance with the appropriate
section in the Maintenance Manual.
