Replacing the handle
An adhesive (e.g. hair spray) is used in these instructions. When applied to
the handle, this substance works as a lubricant and as an adhesive once
dry.
After drying, the adhesive used must be able to resist a pull-off force
of 750 N. If in doubt, contact küschall® AG.
Difficulty:
Remove the old handle.
Remove any residue (residual adhesive, grease, dust) from the push
handle tube.
Apply a thin layer of hair spray all over the surface of the push handle
tube onto which the handle is to be slid.
Apply a thin layer of hair spray to the inside of the handle.
Slide the new handle onto the push handle tube.
Move the handle into the correct position (grooves facing upwards).

If a long handle has been fitted and this is to be replaced with a short
one, the push handle tube must be shortened by 35 mm. The push
handle tube must be replaced when switching from a short to a long
handle.
