Operation
960 PS Series Hydraulic Power Pumps
Do not use this pump in a hazardous
environment. Hazards include
flammable liquids, gases, or other
materials. Using this pump in a
hazardous environment can result in
a fire or explosion.
Failure to observe these warnings
will result in severe injury or death.
Wear eye protection when operating
or servicing this tool.
Failure to wear eye protection can
result in serious eye injury from
flying debris or hydraulic oil.
Changing Accessories
Before changing the hydraulic accessory that is
connected to the pump, follow this procedure for
depressurizing the system.
Procedure for depressurizing the hydraulic system:
1. Disconnect the pump from the power source.
2. Rotate the release lever clockwise.
3. Disconnect the hose slowly to release any
trapped pressure.
Note: Starting the motor without a tool attached to the
pump will cause the pump to immediately build an
internal pressure of 689.5 bar (10,000 psi).
If this happens, shut off the pump and turn the valve
lever clockwise to release the hydraulic pressure.
1. Move release valve lever clockwise.
2. Check reservoir oil level. The oil level should be
within 13 mm (1/2") of the top of the reservoir.
If oil level is too low, refer to “Adding Oil” under
“Maintenance and Service” in this manual.
3. Turn the dipstick two turns counterclockwise.
Note: Operating the pump without loosening the
dipstick will result in poor pump performance.
4. Connect the pump to an appropriate power supply.
5. Start motor and allow pump to idle for a few minutes.
This will allow the hydraulic fluid to work through the
system and prime the pump.
6. Stop the motor. Turn the lever counterclockwise.
7. Start the motor to advance the hydraulic ram. When
finished, stop the motor. Turn the lever clockwise to
release the pressure.
Note: Starting the pump while the lever is in the
clockwise position may cause the ram to extend.
Turning the lever counterclockwise while the pump is
running may release the pressure.
8. During periods of heavy use, occasionally stop the
pump and check the oil temperature. The recommended operating temperature is 38 °C to 50 °C
(100 °F to 125 °F).
9. Tighten the dipstick.

Maintenance and Service
960 PS Series Hydraulic Power Pumps
Maintenance Schedule
Every time the pump is used:
• Check the oil reservoir level. The oil level should be
approximately 13 mm (1/2") from the top of the reservoir. If the oil level is low, refer to “Adding Oil” in this
section of this manual.
• Listen for unusual noises and observe the operation of
the pump for changes in performance. Either situation
may indicate that maintenance or repairs
are necessary.
Periodically:
Examine the hydraulic oil for changes in color or viscosity,
and the presence of dirt or other contamination.
Cleaning
• Periodically clean the exterior of the pump and motor.
Use a vacuum cleaner to clean the ventilation open-
ings.
• Clean the area around the reservoir vent, and be sure
the vent breather hole is open.
• Keep all hose connections clean and use protective
caps or plugs when couplers are not in use.
Inspecting Oil
Inspect the oil occasionally. A change in appearance,
such as darkening or thickening, indicates that the oil
needs to be replaced. Continued use of the oil after it
should be replaced will cause accelerated wear of
system components and will void the warranty.
Adding Oil
Do not use brake fluid. Brake fluid will ruin the seals.
Refer to the “Specifications” section of this manual to
determine the correct type of hydraulic oil and Greenlee
part number.
1. Rotate the valve lever in the clockwise position.
2. Disconnect the pump from the power supply.
3. Clean the area around the fill hole.
4. Remove the reservoir pipe plug.
5. Use Greenlee hydraulic fluid or an equivalent high
grade light hydraulic oil. Refer to “Specifications” in
this manual.
6. Pour the oil through a clean funnel with a filter
screen.
7. Add oil until the oil level is within 13 mm (1/2") from
the reservoir cover.
8. Replace the pipe plug.
Purging (Bleeding) Air from the System
Erratic performance may be caused by air in the
hydraulic fluid.
Note: Position the pump so that it is above the
accessory. Position the accessory so the hose
connection is upward. This will allow any air in the
accessory to escape into the hose and travel upward to
the pump reservoir.
1. Remove any items (conduit, cable, etc.) from the
hydraulic accessory.
2. Rotate the valve clockwise.
3. Turn the dipstick two turns counterclockwise.
4. Connect the pump to an appropriate power supply.
5. Start the hydraulic pump and advance the ram
(hydraulic cylinder) of the accessory to a full stroke
and repeat several times. Stop pump and rotate
valve clockwise to retract ram. As the ram retracts,
the oil in the hose will return to the reservoir in the
pump.
Draining and Flushing the System
1. Thoroughly clean the pump exterior.
2. Remove the motor mounting plate screws.
3. Remove the pump system from the reservoir.
Note: Do not damage the motor mounting plate
gasket, intake screen, or relief valve when removing
the pump.
4. Clean the interior of the reservoir and fill with clean
kerosene. Do not use solvents.
5. Rinse the intake screen.
6. Place the pump system into the reservoir and
replace the motor mounting plate screws.
7. Connect a hose to the pump. Insert the other end of
the hose into the pump reservoir at the fill hole.
8. Run the pump for a few minutes. While the pump
is running, rotate the control lever several times.
Start and stop the pump several times to cycle the
unloading valve.
Note: Do not operate pump for more than a few
minutes as system is not designed to operate with
kerosene.
9. Remove the hose and pump assembly from the
reservoir. Drain and clean the reservoir interior.
Allow the reservoir to dry.
10. Reassemble the pump system.
11. Fill the reservoir. Refer to “Adding Oil” in this section
of the manual.
Motor Maintenance
When repairs are necessary, send the motor to one of
the motor manufacturer’s authorized service stations.
