Risk of injury due to improper lifting
When lifting and handling device components, the weight of the components
and assemblies can result in injury, especially in the torso area.
 Make sure to always have enough people lifting heavy device components
(guideline using metric units: 15 - max. 55 kg / guideline using imperial units:
30 - max. 120 lbs, depending on age and gender). Comply with all the occupa-
tional health and safety regulations and instructions that apply at the installa-
tion location!
 Use suitable hoisting equipment and slings in order to handle heavy device
components. Make sure to take into account the device components' center of
gravity and to attach the slings only to the secure device component locations
intended for this purpose.
 Wear the required personal protective equipment.
Crush and impact hazard posed by components falling or toppling over acci-
dentally.
When working with heavy components that have been removed or are yet to be
installed, injury may result if the components start moving in an uncontrolled
manner, e.g., fall down from the working surface or topple over.
 Place removed components exclusively on level, horizontal working surfaces
with enough load-bearing capacity.
 If necessary, secure removed components so that they will not fall or topple
over.
 Wear the required personal protective equipment.
 Exercise caution when performing the relevant tasks.
Make sure that the following requirements are met:
 The system is not pressurized, see Starting maintenance (see page 41).
