10. Momentarily close the needle valve com-
pletely, record the PSI gauge and immediately
open the needle valve back up._____
CAUTION
This step must be performed very quickly or
damage may occur to the hydraulic system.
11. Record the PSI._____ The new pressure read-
ing is (and replaces the previous reading) (PSI
“C”).
12. Enter the recorded test results from PSI
“B”_____ and the new PSI “C”_____
13. If the recorded PSI “C” is equal to the PSI
recorded earlier (PSI “B”), the pressure relief
valve is functioning correctly, and this is now
the Final PSI “C”._____ Continue to the
Hydraulic Cylinder Troubleshooting section.
14. If the recorded PSI “C” is equal to the PS
recorded earlier (PSI “B”), but exceeds the
3200 PSI limit, the Pressure Relief Valve
Adjustment section must be performed to
lower the PSI._____
15. If the recorded PSI “C” is below the PSI
recorded earlier (PSI “B”), the Pressure Relief
Valve Adjustment section must be performed in
an attempt to bring the PSI back into the cor-
rect specifications before condemning the con-
trol valve.
16. Shut the log splitter off.
17. Repeat the above section and continue to
make eighth turn adjustments until the correct
pressure relief specifications have been
achieved.
NOTE
Always shut the log splitter off when making
adjustments.
18. If the pressure relief valve has been adjusted
to the correct specifications, the control valve
is good. Perform the Hydraulic Cylinder Trou-
ble-shooting section.
19. If the pressure relief valve will not adjust to the
correct specifications, REPLACE THE CON-
TROL VALVE. See Figure 6-90.
20. Shut the log splitter off.
Hydraulic Cylinder Troubleshooting
IMPORTANT: This section is to be performed
after all the other Test Kit sections have been
performed.
1. Enter the recorded test results from the read-
ing Final PSI “C”_____.
2. Rotate the needle valve counter-clockwise to
the completely open position._____ See Fig-
ure 6-91.
