5.1.1.3 Cleaning of the piston/cylinder system

There are a number of ways to clean the individual parts.
It is recommended to wipe the parts with a dust-free, lint-free and soft wipe soaked in alcohol (e.g.
ethyl alcohol), or to pull it through the cylinder, then drying them off with a dry, dust-free, lint-free and
soft wipe.
For this we recommend the use of the cleaning-set for piston/cylinder systems, which is available as
an accessory (see section 8. Accessories). It contains a detailed operating instruction for the cleaning
process.
Never touch the cleaned piston with your bare hands. The natural dermal-grease
can cause a jamming of the piston/cylinder system.

5.1.1.4 Assembly of the piston/cylinder system

Put the parts together again in the opposite order.
Insert the cylinder into the housing (slanted edge facing down)
Screw on the union nut
Place the system vertically on the plate and carefully insert the piston from above. The piston
should "fall" into the cylinder by its own weight.
Tighten the knurled nut again
Never press the piston forcibly into the cylinder.
Otherwise it is damaged.
The system is now ready to use again.

5.1.2 Weight Set

The weights should be handled with gloves.
If fingerprints or other impurities are found on the weight pieces in spite of this precaution, they
can be removed with alcohol (spirit).

5.2 Wear Parts

The O-rings in the pressure connections for the piston/cylinder system and the test specimen are
subjected to wear. Both O-rings must be checked for proper seat and any wear before any calibrating
is performed. If necessary, the O-rings must be replaced in regular intervals, or whenever necessary
(see Accessories, section 8).
Important: Use original seals only. Seals having deviant measurements, or
materials, or material grades, may cause damage to the device and test
specimen, and pose a danger for the operator.
