General Maintenance Continued
Draining and Flushing the Reservoir
Clean the pump exterior before the pump interior is removed from the reservoir. Remove and discard the
screws fastening the motor and pump assembly to the reservoir.
Caution: Do not damage the pump filter or pressure regulating valves when lifting the pump and motor
off the reservoir. See Figure 12.
Clean the inside of the reservoir, and fill with Power Team hydraulic fluid. Rinse the filter clean.
Place the pump and motor assembly back onto the reservoir, and secure with two machine screws assembled
on opposite corners of the housing.
Refer to priming procedure. Place the hydraulic flow control valve in the neutral position. If the pump is
equipped with a valve that has only an advance or retract position, place the valve in the advance position, and
connect a hose to the advance port on the valve. Place the other end of the hose into the fluid filler plug hole.
Run the pump for several minutes.
Disconnect the motor and pump assembly, and drain and clean the inside of the reservoir.
Fill the reservoir with Power Team hydraulic fluid.
Place the pump and motor assembly (with new gasket) on the reservoir, and thread the new screws.
Tighten screws securely and evenly.
There are roll cages and carry handles that are shown on the front page that will need to be addressed before
you can remove the screws that fasten the pump assembly to the tank........
Lubrication (Air Driven Motor Only)
If the pump is operated on a continuous duty cycle, or at maximum speeds for extended periods, install an
automatic air line oiler in the air inlet line as close to the pumping unit as possible. Set the oiler to feed 1–3
drops of SAE No. 10 oil per minute into the system (one drop for every 1.4–2.1 M
refer to the air motor manufacturer's instructions.
Hose Connections
: To prevent personal injury from leaking hydraulic fluid, seal all hydraulic connections
with a high-quality, non-hardening, pipe thread sealant.
IMPORTANT : Sealant tape or non-hardening sealer tape can be used to seal hydraulic
connections if only one layer of tape is used. Apply tape carefully, two threads back, to prevent
it from being pinched by the coupler and broken off inside the system. Loose pieces of sealant
could travel through the system and obstruct the flow of fluid or cause jamming of precision-fit
parts.
Storage
Store the unit in a dry, well-protected area where it will not be exposed to corrosive vapors, dust, or other
harmful elements. If a unit has been stored for an extended period of time, it must be thoroughly inspected
before it is used.
