3.3 CLAMPING NUT ON ADJUSTABLE HANDLE
The clamping nut is captive (cannot be lost) and is designed to clamp the
height-adjustable handle unit in place. The clamping nut features a
special design that allows it to be tightened by hand. It is not
necessary to tighten the nut with force. To find out how far the
clamping nut should be tightened, Sano recommends rotating the nut
clockwise with the handle positioned low down so that the operator can
attempt to push the handle downwards using the weight of the upper
body. Keep tightening the nut until
the handle cannot be shifted. Very little force is applied to the handle
while moving on steps since the stairclimber is balanced while in
operation. The only time slight pressure is needed is while tilting the unit
during loading and unloading. Loosening the clamping nut by one turn is
quite sufficient for the handle to slide easily. The clamping range setting
is adjusted using a concealed setting screw (patented design), which
also acts as a safety screw and may only be adjusted by an approved
workshop. There is no point in undoing the nut any further since the
clamping range does not change. After approximately three turns the
clamping nut is blocked so that it cannot be lost.
NOTE
If the clamping nut cannot be undone, then it usually is already undone. Please check whether the
handle slides freely up and down, or whether you can see a section of exposed thread between
the nut and the handle.
NOTE
The following general rule applies for setting the height of the handle: The upper edge of the
handle (where the UP/DOWN switches are located) should be at about the same height as the
operator's shoulders (see also section
4.1 ).
