PREVENTIVE MAINTENANCE
IMPORTANT:
•
Any repair or servicing that requires dismantling the pump must be performed in a dirt-free
environment by a qualified technician.
•
Dispose of machine and fluids properly.
Lubrication
For Hand/Foot, Manual Valve, and Remote Control Operated Pumps:
If the pump is operated on a continuous duty cycle for extended periods, the manufacturer recommends installing an
automatic air line oiler in the air inlet line as close to the pumping unit as possible. Set the unit to feed approximately
one drop of oil per minute into the system. Use SAE grade oil, 5W to 30W.
For Tandem Pumps:
These models have an integral air pressure regulator, air filter and lubricator. Set the lubricator to feed one drop of oil
per minute to the system. Use SAE grade oil, 5W to 30W. For servicing the air regulator, lubricator and filter system,
see the operating and service instructions provided.
Bleeding Air From The System
During the first moments of operation or after prolonged use, a significant amount of air may accumulate within the
hydraulic system. This entrapped air may cause the cylinder to respond slowly or behave in an unstable manner. To
remove the air, run the system through several cycles (extending and retracting the cylinder) free of any load. The
cylinder must be at lower level than the pump to allow air to be released through the pump reservoir.
Inspecting The Hydraulic Fluid Level
Check the fluid level in the reservoir after every 10 hours of use. Drain and replenish the reservoir with Power Team
hydraulic fluid after every 300 hours of use approximately.
For pumps with a 105 cubic inch (1.7 l) reservoir capacity:
The fluid level should be 1/2 inch (12.7 mm) from the filler/vent cap with all cylinders retracted.
For pumps with a 2 gallon (7.6 l) reservoir capacity:
The fluid level should be 1-3/4 inch (44.5 mm) from the filler/vent cap with all cylinders retracted.
Draining And Flushing The Reservoir
IMPORTANT: Wipe the pump exterior completely clean before attempting this procedure!
1. Remove the screws that fasten the pump assembly to the reservoir. Remove the pump assembly from the
reservoir. Do not damage the gasket, filter or safety valve.
2. Drain the reservoir of all fluid and refill half full with clean hydraulic fluid. Rinse the filter clean.
3. Place the pump assembly back onto the reservoir, and secure with two of the machine screws assembled in
opposite corners of the housing.
4. Run the unit for several minutes. Use the same method described in the section titled "Priming the Pump Unit."
5. Drain and clean the reservoir once more.
6. Refill the reservoir with Power Team hydraulic fluid and replace the pump assembly (with gasket) on the reservoir
and install the screws. Torque the screws as follows: For 105 cubic inch (1.7 l) reservoirs, torque to 25 to 30 inch
pounds (2.8 to 3.4 N•m); for 2 gallon (7.6 l) reservoirs, torque to 35 to 45 inch pounds (4.0 to 5.0 N•m)
IMPORTANT: Drain and clean the other hydraulic system components (hoses, cylinders, etc.) before
reconnecting them to the pump. This will prevent contaminated fluid from entering the pump again.
