Disassembling the pilot and maintaining the base plate
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.
The maintenance described below uses the two-stage pilot as a reference. Refer to the spare
parts lists to make sure that you replace all the maintenance parts relevant to your device
model during maintenance.
Observe the following cleaning instructions:
▪
Before assembly, all parts must be cleaned in order to remove any foreign particles
(swarf) and soiling.
▪
If fasteners (screws, washers, etc.) are replaced with identical new parts, any oil on
these new parts must first be removed.
Proceed as follows:
