riods must be strictly observed.
• If the mixer is fixed to a steel structure, ensure that the structure is sufficiently strong.
Use fixation materials with sufficient strength!
Use suitable materials to avoid electrochemical corrosion!
• Tighten all screwed connections. Observe torque specifications.
