Replacing gas struts
Bottom stage elevation assistance is provided by a gas strut located
in the telescopic column. To allow for various column loads, three
versions of the strut
are available, each
designed to operate
over a particular load
range.
To replace the bottom
stage gas strut:
1. Apply the wheel
brakes (14), set the
top stage (4) to its
maximum height
and engage the top
clamp (19).
Maintenance
Skid clamp adjustment
The top clamp is applied by pulling the ip lever out. The skid clamp
is applied and released by turning the handle clockwise or counter-
clockwise. The skid clamp is tted with a push-on/pull-o type ratchet
adjustment. The top clamp has a ip lever.
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.
