Operating Instructions
BLEEDING AIR from the SYSTEM:
After use, air may accumulate in the hydraulic system if the reservoir level has
been permitted to get too low. This air will cause the cylinder to responded in an unstable or slow manner. To
remove this air:
A. If the pump is positioned above the cylinders:
1. The hydraulic cylinder(s) must be positioned on their side with the couplers pointed upward.
2. Remove any load from the cylinder(s) and cycle the hydraulic system through several cycles (fully extend and
retract the cylinders).
B. If the pump is located below the cylinders:
1. Loosen cap screw on top of cylinders and start pump.
2. When oil replaces the air excaping (bleeding) from loosened screw in cylinder, stop pump and retighten the
screws.
DRAINING and FLUSHING the RESERVOIR:
The reservoir should be drained, flushed, and refilled with
Power Team hydraulic oil after approximately 300 hours of use.
1. Clean the pump exterior before the pump unit is removed from the reservoir.
2. Remove the screws that hold the motor and pump assembly to the reservoir.
Important: Do not damage the
gasket or bump the filter or hydraulic pressure regulating valves when lifting the pump and motor off the
reservoir.
3. After disposing of the used oil, clean the inside of the reservoir and fill with a suitable flushing oil. Rinse the filter
clean.
4. Place the pump and motor assembly back onto the reservoir and secure it with two machine screws assembled
on opposite corners of the housing.
5. Connect a hose to the advance port of the valve and place the other end of the hose into the oil filler plug hole.
6. Run the pump on "advance" for several minutes.
7. Remove the motor and pump assembly from the reservoir. Drain and clean the inside of the reservoir.
8. Fill the reservoir with Power Team hydraulic oil. Place the pump and motor assembly (with gasket) back on the
reservoir and tighten the screws securely and evenly.
HYDRAULIC FLUID LEVEL
•
Check the oil level in the reservoir after each 10 hours of use.
•
Proper oil level is within 1/2" of the filler plug when all cylinders are retracted.
ADDING OIL to the RESERVOIR
•
Use only Power Team hydraulic oil (215 SSu @ 100° F).
•
Clean the entire area around the filler plug before removing the filler plug.
•
Use a clean funnel with filter when adding oil.
•
Cylinder(s) must be fully retracted and the power supply disconnected when adding oil to the reservoir.
MAINTENANCE CLEANING
•
Keep the outer surface of the pump, all hose connections and any equipment hooked up to the pump as free of
dirt and oil as possible.
•
The breather hole in the filler cap must be kept clean and unobstructed at all times.
•
All unused couplers are to be sealed with thread protectors.
•
Change oil as recommended.
