Incorrect repairs can be extremely dangerous for the user!
To prevent electric shocks, please observe the following tips:
• In the event of faults, housing and frame may be live!
• Touching live components inside the appliance may cause dangerous currents to flow through your
body!
• Unplug the appliance before repair!
