Please inform your customer as following: Stair Climber standard model TR 3, produced up to end 1988!
It is not longer possible to deliver for that model following spare parts:

TKD-59 Fahrschalter
TKD-14 Schalter – Zwischenstück
TKA-33 Schalthebel (Walze)
TKA-37 Schalter – Zwischenstück
TKA-38 Bowdenzug auf/ab
TKA-63 Not-Aus Knopf

For these reasons, and because the Stair Climber with its bowden cable operation for up/down and to emergency stop does not correspond, any more the today’s regulations! We recommend to take these units from market.
