Troubleshooting - Greenlee LHFS-210001 Operation, Service And Parts Instruction Manual

Troubleshooting

Before You Begin
1. Tool must be connected to the correct power source
system. See Tool Specifications (page 6) for the
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-
engaged, 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, hose or power source as the
problem area. The following steps will help to
determine the problem area.

Determine the Problem Area
1. Check the power source flow and pressure if the
proper gauges and tools are available. If these
items are not available, proceed to the next step.
2. Stop the power source.
3. Disconnect the tool from the hoses and power
source.
4. Connect a known working 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 working tool operates, the problem is
in the disconnected tool. See the Troubleshooting
charts in this operator's manual.
If the known working tool does not operate, the
problem is likely to be in the hoses or the power
source. Proceed to next step.
5. Stop the power source.
6. Disconnect the existing hoses from the known
working tool and power source.
7. Connect a different set of hoses to the known
operating tool and power source. Start the power
source.
If the known working tool operates with the different
set of hoses, the problem is in the disconnected
hoses.
If the known working tool does not operate, the
problem is in the power source. See your power
source operator's manual for troubleshooting.
