Operation
Height adjustment
The column has an on-shot stroke of 770 mm (30.3 in) and the load
can be moved over this distance, in perfect balance, by raising and
lowering the steering ring (22). The movement is adjustable for drag
(20) and an on-shot clamp (21) can be used to hold the moving
column in position if fixed height operation is required.
Drag control
Column movement is adjustable for drag and this is set according to
operator preference by means of the drag control (20) located at the
top of the outer tube. Turn the control clockwise to increase the drag
setting, and counter-clockwise to decrease it.
On-shot clamp
An on-shot clamp (21) can be used to hold the moving column in
position if fixed height operation is required. Move the clamp lever
fully to the left to apply the clamp. Move it fully to the right to release
the clamp.
