7 Troubleshooting and Repair
Bastian Solutions Conveyor encourages using the following troubleshooting techniques before contacting
a Bastian Solutions Conveyor representative as these are the same techniques used by our field service
engineers. To assist in data collection, Bastian Solutions Conveyor asks that any issues that arise be
recorded in a log, with the mark number, a description of the issue, and the steps taken to resolve the
issue. In case of a failure with unknown cause, do not discard broken or defective parts without checking
with our field service team, since the parts may be needed for warranty claims information or in
troubleshooting the root cause of the failure.
