WARNING
Risk of impact
If the drive falls when work is being carried out, it can hit someone and cause
injury.
1. During installation and when dismantling, make sure nobody is located be-
low you.
2. During installation, make sure the rotary drive cannot come loose. The
same applies over longer periods, taking into account external influences
such as vibration, corrosion etc.
WARNING
Finger twisting
At the open end of the shaft, there can be unexpected rotational movements,
e.g. if the rotary drive is accidentally switched on or if the return spring is
triggered by a power outage.
1. Never stick your fingers into the open end of the shaft.
2. Only operate the rotary drive once it is installed.
3. Turn off the power to the rotary drive before starting work to avoid it be-
ing started unexpectedly.
CAUTION
Possible damage to musculoskeletal system
Working in positions with an adverse body posture can result in orthopaedic
injuries.
1. Make sure you are working as ergonomically as possible.
2. Use appropriate tools, e.g. steps for easy access.
3. Wear personal protective equipment: headgear and gloves.
