11 TROUBLESHOOTING
11.1 General
11.1.1 Think before you act
Upon noting a defective indication, recall what you
did the last time when you came across the same
indication. If what you did was correct and
successful, do the same again. If the symptom
noted is new to you, think of a possible cause in
accordance with the troubleshooting procedure
which follows.
11.1.2 Dust and dirt are often the main
causes
“Wear” is usually the result of abrasive particles.
When disconnecting or disassembling a part or
component, be sure to keep out dust and dirt.
11.1.3 Use original parts
Use only original parts to replace those that have
failed or reached their service limits. When
ordering, specify the needed replacement parts by
referring to the Parts Catalogue.
11.1.4 Perform servicing work safely
Use the right kind of hand tools to carry out each
working step in repair work. Avoid injury to
yourself and damage to the parts by using proper
tools. When lifting or carrying a part that is too
heavy for one person to handle, get another
person’s help and, if necessary, use a jack or a
hoisting device.
