Maintenance
The life of your Greenlee Fairmont hydraulic tool will
be extended with proper care and handling. The preven-
tative maintenance checks listed below are suggested
on a regular basis and whenever needed.
Daily:
• The operator should wipe all exposed surfaces clean
of dirt and foreign material. Inspect hydraulic hoses
and couplings every operating day. Repair or replace
if cracking, wear or damage is evident.
Monthly
• Make a detailed inspection of hoses and connections.

Troubleshooting
Before You Begin
1. Verify that the pressure and return hoses are con-
nected properly to the tool and power source ports.
2. Power source reservoir must be filled to FULL level
with hydraulic fluid.
3. Start the power source. All power source shut-off
devices must be engaged or opened (clutch en-
gaged, separate on/off valves open, etc.).
4. 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. Check 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. Disconnect the existing tool
from the hoses and power source.
3. 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 the next step.
4. Stop the power source. Disconnect the existing
hoses from the known working tool and power
source.
5. Connect a different set of hoses to the known
working 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.
