> Check the equipment for correct functioning before each use. Do not use the
product if parts are missing or damaged.
Persons under the influence of drugs, alcohol or medication reducing reaction
times must not be allowed to handle or work on or with the platform steps.
The following safety instructions must be observed when:
• working with electrical equipment on the platform steps
• using the platform steps in the vicinity of electrical units
• using the platform steps in the vicinity of overhead power lines
