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 fixa-
tion. 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.
•
Wear protective equipment! Observe the work regulations.
–
Protective gloves: 4X42C (uvex C500 wet)
–
Safety shoes: Protection class S1 (uvex 1 sport S1)
–
Wear a safety harness.
