Maintenance - REHOBOT CH Series Gebrauchanweisung

Overloading
Do not lift any load that exceeds the rated capacity of the ram.
Overloading may damage the equipment and cause personal
injury. A ram can support maximum load on the piston stop ring/
glands. However, avoid loading a ram when it is fully extended
as this causes unfavourable stresses. Therefore choose a ram
with a slightly longer stroke than is necessary for the intended
application.
Heat
Avoid exposing hydraulic equipment to temperatures higher than
60°C. Heat can destroy gaskets and hoses.
Accessories
The following pressure heads are available for all models:
THH – Pressure head with unthreaded hole *
THM – Pressure head with internal M thread *
THU – Pressure head with internal UN thread *
THR – Knurled solid pressure head
TS - Cylinder support plates
Support plates for CHFA cylinders are a simple and foremost
cost effective way to protect the cylinder base against damage.
Cylinder support plates are available for all CHFA cylinders.
*) For information about internal diameters and/or thread sizes,
contact REHOBOT or your nearest REHOBOT dealer.

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 system 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 neces-
sary.

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 type ISO VG10 or equal.

Storage
When hydraulic equipment is not in use:
Clean the equipment, make sure the hydraulic system is not
pressurized and store it somewhere clean and free from damp.
Make sure the equipment is not subject to extremes of tempera-
ture.
Hoses
Do not let hoses become twisted or sharply bent. If hydraulic
pressure is applied to a distorted hose it can cause an unfavour-
able 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 connec-
tions, or carry hand pumps by the lever unless it is fitted with a
lever lock.
Aluminum cylinders
• Note! The REHOBOT range of CHFA aluminium cylinders
are aimed to be used intermittent and in low-cycle
applications such as normal maintenance and lifting
operations. These aluminium cylinders are designed to
provide a lifetime of at least 5.000 cycles and should
therefore NOT be used in high-cycle operations like pro-
duction lines etc. Use of these cylinders beyond their
rated life can lead to sudden failure without warning
and could cause property damage, injury, or death.
Recycling
Hydraulic oil that is drained when servicing the jack must be col-
lected and handled according to applicable environmental laws
and regulations.
The various parts can be recycled at the end of their service life.
The unit consists of steel, hydraulic oil, rubber (seals), and plas-
tic. Collect the hydraulic oil and dispose of it separately. The unit
does not contain any pressurized components when released
from load. For more information about recycling of this product,
please contact the local authorities, your waste disposal service
or your provider.
