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.
