Check the following points regularly, but at least daily:
▪
The platform must not start up until the swing door is locked.
▪
It must not be possible to open the swing doors when the platform is not in the landing.
▪
When the contact bar or the safety bottom on the platform is actuated, the platform must stop
immediately.
▪
The platform must stop independently when reaching the stops.
▪
When releasing the drive command button, the platform must stop without a longer overrun.
▪
The emergency stop button must shut down the entire system when pressed.
▪
If an emergency call is available, it must always work.
9.2 Cleaning
Clean the unit at regular intervals to remove dust and dirt. Please observe the following points:
▪
For safety reasons, the lift must always be taken out of operation before cleaning.
▪
Never use cleaning agents that require special ventilation.
▪
Do not use aggressive cleaning agents to clean plastic-coated or painted surfaces.
▪
Stainless steel surfaces should be treated with a commercially available cleaning agent (stainless
steel care spray, slightly greasing), do not use scouring powder.
▪
The push buttons must never be treated with cleaning sprays or the like (sticking of the buttons
is possible!). The floor should be wiped with a damp dust rag.
▪
Avoid wetness, especially with the operating elements (no splashing water).
▪
Further maintenance work may only be carried out by authorised partner companies.
