CLEANING
Cinders and dirt inside the hydraulic installation cause bad working and precocious wear.
Before assembling, it is necessary to clean the different parts with a lot of care:
- All the possible protection caps, plastic bags and tape used for packing have to be removed.
- The connection pipes, whether they are flexible or iron have to be cleaned perfectly from the inside.
Especially the iron pipes have to be cleaned from the inside and cinders have to be removed from
the ends. A pipe bender, not flame, has to be used to bend the iron pipe.
- Before pouring the oil into the pump unit tank, check that no dirt or water is inside it.
- Use always a good filter to pour or add oil in the tank.
- For the cleaning of the pipes and the pump unit do not use fraying clothes or steel wool.
- The cylinder head and all the plastic or rubber parts have to be protected if paint, concrete or
welding machines are used in their neighborhood.
- All the parts of the installation which have been disassembled to be tested or repaired, the sealing
surfaces, the pipes and the fittings have to be cleaned perfectly before being reassembled.
INSTALLATION
For the installation or the replacement of the hydraulic installation components, the following points have to
be observed:
- Only use the material advised by OmarLift (especially the hydraulic oil) and the original OmarLift
spare parts.
- Avoid the use of sealing materials such as silicone, plaster or hemp which could penetrate the
hydraulic circuit.
- In case of pipes bought directly from the market are being used, only choose the ones responding to
the safety measures in force and according to the pressure of the installation. Note that the only use
of the hard pipe to connect the pump unit to the cylinder can transmit and increase the noise.
- Install the flexible hoses with the right bending radius suggested by the manufacturers and avoid the
use of hoses which are longer than necessary.
MAINTENANCE
During the periodical works of maintenance besides normal tests, it should be remembered that:
- The damaged pipes have to be replaced immediately.
- Get rid of oil leakage and its causes.
- The possible spilled oil has to be collected, so that leakage can be easily detected.
- It’s necessary be sure that there are no unusual and excessive noises in the pump, the motor or the
suspensions. Eventually, get rid of them.
ANTI-POLLUTION MEASURES
Possible spilled oil from the circuit during repair operations has not to be spread in the environment, but has
to be promptly collected with cloths or sponges and disposed carefully in proper containers. In case of oil
replacement, also the waste oil has to be disposed in proper containers.
For the disposal of oil and clothes containing oil contact the specialized companies according to the
regulations in force in the country of operation. Concerning the rules against the water pollution (see
underground direct acting installations with high quantities of oil) act according to the national rules.
1.5 CONTROL OF THE SUPPLIED MATERIAL
When the material is withdrawn before signing the delivery document of the forwarding agent, check that the
goods correspond to the list reported in the delivery document and to the requested order.
1.6 IDENTIFICATION PLATES
The main supplied components have their own plate containing all the data needed to identify them:
- Cylinder: adhesive plate on the cylinder head.
