Troubleshooting - Greenlee fairmont H8508 Instruction Manual

Troubleshooting

Before You Begin
1. Tool must be connected to the correct power source
system. See Tool Specification for type of hydraulic
system required. Verify the power source hydraulic
system.
2. Verify that the pressure and return hoses are
connected properly to the tool and power source
ports.
3. Power source reservoir must be filled to FULL level
with hydraulic fluid.
4. Start the power source. All power source shut-off
devices must be engaged or opened (clutch en-
gaged, separate on/off valves open, 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 tool, hoses or power source as the
problem area. The following steps will help to
determine the problem area.

Determining the Problem Area
1. Stop the power source. Disconnect the existing tool
from the hoses and power source.
2. Connect a known, properly operating tool to the
hoses and power source. See the tool's operator's
manual for correct hook-up procedure. Start the
power source.
If the known, properly operating tool operates, the
problem is in the disconnected tool. See the trouble-
shooting charts in this operator's manual.
If the known, properly operating tool does not
operate, the problem is likely to be in the hoses or
the power source. Proceed to Step 3.
3. Stop the power source. Disconnect the existing
hoses from the known, properly operating tool and
power source.
4. Connect a different set of hoses to the known,
properly operating tool and power source. Start the
power source.
If the known, properly operating tool operates with
the different set of hoses, the problem is in the
disconnected hoses.
If the known, properly operating tool does not
operate, the problem is in the power source.
See your power source operator's manual for
troubleshooting.
