Function Tests
Fundamentals
The Function Tests are designed to discover any
malfunctions before the machine is put into
service. The operator must follow the step-by-step
instructions to test all machine functions.
A malfunctioning machine must never be used. If
malfunctions are discovered, the machine must be
tagged and removed from service. Repairs to the
machine may only be made by a qualified service
technician, according to the manufacturer's
specifications.
After repairs are completed, the operator must
perform a pre-operation inspection and function
tests again before putting the machine into service.
