Chapter 2:

Common Issues

he Hydrobar Sprint 555 is designed to be a user-friendly, simple, and reliable bar feeder, covering a range of diameters
0.250” to 2.000” (up to 2.125” with bar end preparation). Although easy to use, including extremely quick changeovers and
the capability for unmanned operation this unit is not flawless. A list of common issues that have been documented by
service technicians and problems relayed back from customers has been compiled in this manual. This chapter discusses
the most common problems that have been observed. Along with each problem, a brief description is given as well as

quick reference charts of symptoms/solutions, sequences, and procedures for adjustments, changeovers and alignment.
