HON 670 / HON 671 Controllers Component Documentation
Crush and impact hazard posed by components falling or toppling over accidentally.
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.
