Introduction

CAUTION

Further work

This Operation Manual may be used to carry out only the work described in
it. Further work that is carried out in an incorrect way can lead to serious
damage to the machine.

ABB Turbocharging recommends having further work carried out only by
trained personnel from an ABB Turbocharging Service Station.

Mark the casing position for assembly.

Not all tools are marked with a part number. Identification is guaranteed by the tool list. This
list is enclosed with the tool set.

WARNING

Servicing the tools

The tools must be checked for damage before and after use.

Visually inspect for corrosion, cracks, deformation and wear.

Damaged tools must no longer be used and must be replaced.
