Maintenance
Attention
For installation, maintenance and repair work all poles of the power supply must be disconnected from the
step feeder in compliance with VDE provisions. Any work on electrical equipment of the step feeder shall
be carried out exclusively by a professional electrician, or by instructed persons (see chapter 2) working
under the direction and supervision of a professional electrician, according to electrotechnical rules.
Clean the step feeder at regular intervals to ensure smooth mechanical action. The cleaning intervals are to be set by
the user depending on the condition of the parts to be handled and on the specific ambient conditions prevailing at site
but should not be longer than once a week. During cleaning, check the sliding skids on the step plates for wear and
apply a thin layer of oil. The sliding skids prevent the metal components from touching each other. Replace the sliding
skids when the gap sizes are reduced to approx. 0.1 to 0.2 mm.
Check the following once a day:
1. Absence of foreign matter or rejects in the equipment
2. Tight fit of machine parts and proper transition areas
3. Tightness of spring steel plates of steps
If any one of these points is not fulfilled stop the equipment and initiate repairs and/or adjustments.
