The Flo-Check USB Hydraulic System Analyzer is designed to give years of trouble-free service However, if trouble is
suspected, a few simple checks can be made
PC Connectivity
If there are connection issues with newer versions of Windows:
1 Make sure the unit and PC are connected with a USB A/B cable

Load Valve
If the valve fails to load the system, remove the valve body and check for foreign material, worn parts or seals
Flow
The absence of any flow reading may indicate a blockage of the turbine
1 Remove the retaining ring from the inlet port and carefully remove the turbine assembly Remove any material that may
be preventing easy rotation of the rotor
2 Reassemble and attempt a flow reading again
3 If the tester still fails to indicate flow, return the tester to the factory For return procedures, see
"Return Goods Authorization" on page 27
Burst Discs
The burst discs are designed to rupture at a specified pressure Testers provide protection from excessive pressure in either
direction (7500 PSI differential) with two internal burst discs that, when ruptured, bypass flow around the loading valve If
rupture occurs, replace the burst discs
WARNING
IF YOU DO NOT HAVE THE PROPER TOOLS TO ACCOMPLISH THIS TASK, RETURN THE TESTER(S) TO THE FACTORY FOR
REPLACEMENT OF THE BURST DISC HOUSING AND THE BURST DISCS. INJURY TO PERSONNEL AND/OR DAMAGE TO
EQUIPMENT MAY RESULT IF THE BURST DISCS ARE INSTALLED IMPROPERLY.
