RYCO RY16-16 - Pump Operation; Operating the Pump

10 MINI CRIMPER SERIES OPERATION MANUAL
OPERATION
HYDRAULIC HAND PUMP
Before Using the Pump
1. Inspect all system ttings and connections to be sure they are tight and leak free.
2. Check oil level in reservoir and add oil if needed. Refer to instruction in
maintenance section.
3. Read and understand the following precautions before operating pumps:
BE CAREFUL: In certain situations the pump handle can “spring back”.
Always keep your body to the side of the pump, away from the line of force of the handle.
BE CAREFUL: Keep hands and ngers away from pinch point area between pump
handle and lifting handle, when operating the pump handle.
CAUTION: Never add extensions to pump handle. Extensions cause unstable pump operation.
CAUTION: To prevent mechanical damage, do not pull on pump handle after it has reached the end of its travel. Do
not apply side force to pump handle.
BE CAREFUL: At the stage of high pressure, take short strokes to reduce handle force.
Maximum leverage is obtained in the last 5 degrees of stroke.
Pump Operation
Two Stage Flow
Under no loading, the pump operates in the high ow stage for fast advance. When the load is contacted, the pump shifts
automatically to the low ow stage to build up pressure. After the pump shifts, priming takes less force.
Note: For the best performance, priming pump handle at moderate speed during the high ow stage. Fast handle speed in the high
ow stage will prevent the pump from delivering full volume of oil.
The RY16-HP is designed for use with single-acting cylinders (Crimper) and is equipped with an integral release valve.
1. Close the release valve by hand by turning dial clockwise until it stops.
2. Open the release valve by hand by turning dial counter-clockwise to release the pressure and allow oil to ow back to the
reservoir.
CAUTION: If release valve dial is difcult to turn or becomes stuck, discontinue using pump immediately.
Have pump inspected and repaired by RYCO authorised dealers.
Operating The Pump
Pump Position
The pump may be used in either the horizontal or vertical position. When operated in the vertical position, hose end of pump must
be pointing down, or the pump will pick up air and will not build up pressure properly.
