A� Remove all packing materials from the assembled unit.
B� Inspect the unit upon arrival� The carrier, not the manufacturer, is responsible for any damage resulting
from shipment�
1. Filling the Pump Reservoir
Most pumps are shipped without hydraulic fluid in the reservoir. Hydraulic fluid may have been shipped in a
separate container, but if hydraulic fluid is needed, use only approved Power Team hydraulic fluid rated at AW
46 47 cSt @ 38°C (215 SUS @ 100°F). If low temperature requirements are needed, use hydraulic fluid 5.1
cSt @ 100°C (451 cSt @ -40°C)�
A� Clean the area around the filler cap to remove dust and grit� Debris in the hydraulic fluid can damage the
polished surfaces and precision-fit components of this pump�
B� Remove the filler cap and insert a clean funnel with a filter�
C� Fill the reservoir with hydraulic fluid to 1�3-3�8 cm (0�5-1�5 in�) from the cover plate�
D� Replace the filler cap� Verify the breather-hole is open, if applicable�
2. Hydraulic Connections
A� Clean the areas around the fluid ports of the pump and tools�
B� Inspect all threads and fittings for signs of wear or damage, replace as needed�
C� Clean all hose ends, couplers or union ends�
D� Remove the thread protectors from the hydraulic fluid outlets�
E� Connect the hose assembly to the hydraulic fluid outlet, and couple the hose to the tool�
: 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
3. Rotary Air Motor Lubrication
The air supply must be minimum 1�4 M
To ensure the pump can operate at a continuous duty cycle, and maximum speeds for extended periods,
RWP55 Series pumps are pre-assembled with a Filter Regulator / Lubricator assembly� Before use, the
lubricator should be filled with SAE 10 oil, up to the level marked on the bowl� With the air motor running, the
Lubricator drip feed should be set to supply 1-3 drops of oil per minute into the system (one drop for every 1�4-
2�1 M /min (49-75 CFM) of air), or refer to the air motor manufacturer's instructions for suggested drip rate�
3
NOTE: Ensure that a filter/regulator/lubricator/assembly is fitted to the air motor prior to use if it is not
pre-installed�
4. Bleeding Air from the System
After all connections are made, the hydraulic system must be bled of any trapped air� With no load on the
system and the pump vented and positioned higher than the hydraulic device, cycle the system several times�
Check the reservoir fluid level and fill to proper level with Power Team hydraulic fluid as necessary� If there is a
problem contact the Power Team�

INITIAL SETUP

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.
