Replacing gas struts
Bottom stage elevation assistance is provided by a gas strut located in the telescopic column. To
allow for various column loads, four versions of the strut are available, each designed to operate
over a particular load range.
To replace the bottom stage gas strut:
Apply the wheel brakes (15), set the top stage (4) to its maximum height and engage the
top clamp.
Remove the load, release the bottom clamp (19) and set the bottom stage (6) to its maxi-
mum height.
Tip the pedestal over and carefully lay it on its side.
WARNING! Set the bottom stage to its maximum height. If this is not done
the gas strut will be under compression. Attempted removal of a
compressed gas strut may lead to serious injury.
