Notes on the selection of oils and greases

Original CGM HMS oils and greases

Besides regular and careful maintenance, the quality of the oils and greases used in the machine has a decisive influence on high performance, reliability and long service life of a machine and of its units and assemblies.

The lubricants tables in the CGM HMS Operating Instructions contain specifications for the oils and greases that are approved for use in CGM HMS machines. These oils and greases are especially adapted to CGM HMS machines and their units and assemblies.

Other oils and greases which do not fulfil the requirements of the specifications can be the cause of premature wear or of damage to and failures of machine units and assemblies.

For this reason, CGM HMS only approves the use of the specified oils and greases. All other qualities are not approved.

Alternative oils and greases

The oils and greases filled into the machine must meet at least the specifications mentioned in the lubricants tables of the CGM HMS Operating Instructions.

In the event of damage to the machine or to its units and assemblies caused by the use of alternative oils and greases that are not compatible with CGM HMS specifications, CGM HMS does not assume any responsibility and does not accept any warranty claims.

Avoid mixing of different hydraulic fluids

The machine has been run in at the factory with BM Long Term Hydraulic Fluid HSS (Part-No. 2482971). CGM HMS recommends using this high-grade hydraulic fluid also in operation as it has been made especially for use in these machines to which it is also perfectly adapted.

If oil analyses are performed regularly and with positive results, the BM Long Term Hydraulic Fluid can remain in the machine for up to 10 000 operating hours.

If an alternative hydraulic fluid is to be used, it must fulfil the same specifications. Please note that the change interval for alternative fluids is fixed at 5 000 operating hours.

There is an increased risk of damage to hydraulic components, if different hydraulic fluids are mixed during topping up as well as when changing over to a fluid of a different type or from another manufacturer.

For topping up, it is therefore necessary to use only same hydraulic fluid as the one that is already in the hydraulic system.

When changing over to an alternative hydraulic fluid, please observe that there is always a small amount of old fluid remaining in the hydraulic system even after the system has been emptied. The mixing of this residual amount of old fluid with the new alternative fluid reduces the properties of the fluid dramatically and can cause damage to components of the hydraulic system in operation.

To avoid this result, the change-over to the alternative fluid must be performed in strict compliance with the manufacturer's prescriptions. The manufacturer must confirm that his hydraulic fluid is compatible with the BM Long Term Hydraulic Fluid. The remaining amount of old fluid must not exceed 2% of the total volume. This can only be achieved by repeated flushing with the total fluid volume.

If the remaining amount of fluid exceeds 2% of the total volume, the fluid becomes a detrimental "mixed fluid".

The operation of the system with mixed fluids must by all means be avoided.

CGM HMS assumes no warranty for damage caused as a result of the machine having been operated with consumables of inappropriate specification or with mixed fluids.
