Because the pump has a rubber bladder fitted inside the tank it can be
used either horizontally or vertically.

Safety feature

The pump is equipped with a safety valve that regulates the output pres-
sure. The safety valve is set to the maximum working pressure at the
factory.
Installation
Connecting compressed air
PP63B-1000 / PP80B-1000 The pump requires a compressed air
pressure of at least 0,6 MPa (6 bar, 87 psi) to develop hydraulic
pressures of 63 MPa (630 bar, 9140 psi) and 80 MPa
(800 bar, 11,600 psi).
PP70B-1000 / PP100B-1000 The pump requires a compressed air pres-
sure of at least 0,65 MPa (6,5 bar, 94 psi)to develop hydraulic pressu-
res of 70 MPa (700 bar, 10150 psi) and 100 MPa (1000 bar, 14500 psi).
Make sure that the air pressure does not exceed 1,2 MPa (12 bar, 174
psi) as this could damage the pump. To ensure efficient operation and
long life use clean compressed air with a water trap and oil mist lubrica-
tion. Connect the compressed air line using a G 1/4" coupling, as shown
in Fig. 2, item A.
Connecting the hydraulic hose
Connect the hydraulic hose using a G 1/4" coupling (Fig. 2, item B) or use
REHOBOT quick couplings. To allow the hydraulic hose to rotate freely use
coupling ASE10. When connecting a hydraulic hose or coupling to the
pump it is important to use a spanner to hold the connector on the pump
and prevent it from turning (Fig. 3).
Bleeding the hydraulic system
When hoses or tools are connected to the pump they can introduce air into
the hydraulic system, which could lead to operating problems. Bleed the
system by running the tool or cylinder through 3–4 cycles (by pumping out
until fully extended, then releasing) with no load. Make sure that the tool or
cylinder is kept lower than the pump to allow the air to flow back into the oil
reservoir of the pump. Then hold the pump with the oil reservoir at the top
while pressing the pump pedal and release pedal at the same time (Fig. 4)
for around 15 seconds. It may be necessary to top up the oil depending on
the volume of air in the connected hoses or tool, see Filling with oil.
Accessories
The pump can be equipped with accessories such as a gauge / gauge
adapter, etc. It is possible to connect a return pipe. All rams, accessories,
and tools that are connected to the pump must be designed for a working
pressure that is equal to or higher than the maximum working pressure of

the pump. NOTE! The pump is equipped with a safety valve on the hydraulic
side. It has been factory-set for maximum working pressure. The safety
valve (Fig. 4, Pos. A) can be adjusted ONLY by REHOBOT or a workshop
authorized by REHOBOT. For simple reduction of the hydraulic pressure, we
recommend you to use a reduction valve for incoming compressed air.
Use
Starting
To extend the cylinder or tool, press the pump pedal (Fig. 5, item A). The
pump will stop and maintain the achieved hydraulic pressure when the
pedal is released in the neutral position.
Releasing
To release the cylinder or tool, press the release pedal (Fig. 5, item B). Hold
the pedal down until the cylinder has moved back to the desired position.
NOTE! If the pump is overfilled when a cylinder or tool is released , the
surplus oil will run out of the valve in the filler plug.

Maintenance

When necessary lubricate moving parts such as the pneumatic piston and
valve with high-grade grease.
Service
Filling with oil
Check the oil level before use. Always measure the oil level with the cylinder
or tool in the lowest or retracted position. To ensure efficient operation use
an hydraulic oil that conforms to ISO VG 10.
• Stand the pump up with the pneumatic motor lowermost (Fig. 6).
• Unscrew the oil filler plug (Fig. 6, item A).
• Fill the oil reservoir through the filler hole until the oil reservoir is
completely full (1,050 cm , 64 in

• Screw the oil filler plug back into place.
For safety reasons, service and repair of this product must be done by a
knowledgeable person. Upon the slightest doubt, contact your distributor
for information about the nearest authorized workshop.
