8.7 Installing the regulator unit
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.
Observe the following cleaning instructions:
Before assembly, all parts must be cleaned in order to remove any foreign
particles (swarf) and soiling.
If screws, bolts, or washers are replaced with identical new parts, any oil on
these new parts must first be removed.
Proceed as follows:
