System design
When you plan a hydraulic system always choose products
that are suitable for the task in hand. Check the limitations of
the product in terms of pressure range, lifting capacity and
connection options. The maximum working pressure of the
system must not exceed the maximum working pressure of
any components of the system.
We recommend the use of a pressure gauge to accurately
determine the safe range of use of any hydraulic systems.
Always make sure that hydraulic hoses and couplings, etc.,
are connected to the correct connection point (pressure or
return connection) on the pump, cylinder, valve or other
hydraulic component. Offset loading (Fig. 2)
In pulling operations it is important that the cylinder is not
subjected to bending (Fig. 2, B). Make sure that the attachment
points are aligned (Fig. 2, A).
Hoses
Do not let hoses become twisted or sharply bent. If hydraulic
pressure is äapplied to a distorted hose it can cause an
unfavourable rise in pressure that may damage the equipment.
If hoses are badly bent or twisted it may lead to internal
rupture and excessive wear.
Do not let sharp or heavy objects rest on the hose or run over
it. Never lift or carry hydraulic components by the hose or
connections
Accessories
When connecting accessories such as chain attachments,
pullers, etc., make sure that these are safely attached.
The capacity rating for tools etc., indicates the maximum force
developed by the tool. When using accessories, such as
spreader lugs, the maximum force cannot be used for reasons
of safety. REHOBOT or a REHOBOT authorised dealer will be glad to give
recommendations for specific applications.
Heat
Avoid exposing hydraulic equipment to temperatures higher
than 50oC. Heat can destroy gaskets and hoses.
Safety
Never disconnect a cylinder from the pump while the hydraulic
system is pressurised.

Never subject a cylinder to offset loading.
Always make sure that accessories, etc., are designed for a
working pressure/capacity that equals or exceeds the
maximum working pressure of the cylinder.
Never stand next to cylinders/accessories during pulling
operations. If a fastening or similar item breaks it could cause
injury.
Bleeding the hydraulic system
Air can collect in the hydraulic system when hoses or tools
are connected and this can lead to problems in operation. To
bleed the äsystem run the tool or ram through 3-4 cycles
(pumping to full extension then releasing) without any load. At
the same time make sure that the tool or ram is kept lower then
the pump so that air can travel back to the oil reservoir in the
pump. Then bleed the pump oil reservoir. Top up the pump with
oil if necessary.
Maintenance
Hydraulic equipment must be serviced and maintained
regularly to keep it in good working condition. For safety
reasons it is important that hydraulic products are serviced
and maintained by experienced personnel. If in any doubt,
contact your dealer for information about the nearest
authorised service agent. Always use original REHOBOT spare
parts.
Lubricate moving parts as necessary with a high quality
grease. Always use high quality hydraulic oil with good low
temperature äproperties.
Storage
When hydraulic equipment is not in use:
Clean the equipment, make sure the hydraulic system is not
äpressurized and store it somewhere clean and free from
damp. Make sure the equipment is not subject to extremes of
temperature.
