Maintenance
Skid clamp adjustment
The skid clamp is applied and released by turning the handle
clockwise or counter-clockwise. The handle has a push-on/pull-off
type ratchet adjustment.
To adjust the skid clamp pull the clamp handle away from the spindle,
rotate it 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 on the elevation tube
or top stage
If excessive radial or side play is apparent on the elevation tube or top
stage. Then this adjustment should be carried out by a competent and
suitably trained 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 trained person.
