Troubleshooting

Before You Begin
1. Any tool used with this power unit must be an
open-center system type tool.
2. Verify that the pressure and return hoses are con-
nected properly to the power unit and tool ports.
3. Power unit reservoir must be filled to the FULL mark
with hydraulic fluid.
4. Start the power unit hydraulic oil flow. All separate
shut-off devices must be opened (ON/OFF valves,
etc.)
5. After verifying all of the above, check the tool to see
if it operates.
If the tool does not operate, it will be necessary
to pinpoint the power unit, tool, or hoses and the
problem area. The following steps will help to deter-
mine the problem area.
