CAUTION
Material damage due to incorrect fixation
Defective fixation may limit the functionality of the mixer or damage it.
• If the mixer is fixed to a concrete structure, use anchor bolts for fixation. Follow the
manufacturer’s installation instructions! Temperature specifications and hardening
periods 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.
