5.4 Preventive measurements for winter operation
In order to warrant a faultless operation of the Ruthmann-Steiger during
winter time, at temperatures below zero, among other things, the following
preventive measurements must be carried out.

Keep the door locks running free and free of ice.

Avoid accumulations of water remains. Draining holes for water must be
free.

Check the sensory system for cleanness. All limit switches and ap-
proach switches must be kept free of snow and ice

Ensure softness of rubber buffers.

Keep steps and floor of working cage free of snow and ice.

Ensure that the retraction and extension chains are free of ice.

Gliding parts in and at components must not be frozen.

The spring drive (flat coil) of the cable / hose drum must not be frozen.

Take care of an oil exchange in the hydrostate in case of extreme cold
temperatures. This can be achieved for example through a lower speed
of „Steiger-movements“.
