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 pressure. The safety valve is set to the maximum wor-
king pressure at the factory.
Installation
Connecting compressed air
The pump requires a compressed air pressure of at
least 0.65 MPa (6.5 bar, 94.3 psi) to develop hydraulic
pressures of 227.5MPa (2275 bar, 33000 psi).
Make sure that the air pressure does not exceed 1.0 MPa (10
bar, 145 psi) as this could damage the pump. To ensure ef-
ficient operation and long life use clean compressed air with
a water trap. Connect the compressed air line using a G 1/4"
coupling, as shown in Fig. 1, item B.
Connecting the hydraulic hose
Connect the hydraulic hose using a G 1/4" coupling (Fig. 1, item
H) or use REHOBOT quick couplings. 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 intro-
duce air into the hydraulic system, which could lead to opera-
ting 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 hig-
her 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 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 hydrau-
lic 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
•
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 aut-
horized workshop.
