Visual Inspection Of The Filling And Breathing Filter (See Fig. 1, Pos. 6); Pressure Value Check; Hydraulic Fluid Care; Visual Inspection For Leakage, Cracking, Force Effects And Corrosion - Bosch Rexroth CytroPac Operating Instructions Manual

10.5.5 Visual inspection of the filling and breathing filter (see fig. 1, pos. 6)

▶ Carry out an annual visual inspection and replace the filling and breathing filter as
necessary.
▶ If the air filter is used as described in chapter 8.1.2 "Filling the hydraulic
system", annually carry out a visual inspection and replace the air filter in case of
contamination and/or damage.

10.5.6 Pressure value check

The pressure values need to be checked in case of any changes in drive behavior
(e.g. increased cycle time, end product quality, etc.). Otherwise, semi-annual
inspections are recommended.
Bosch Rexroth recommends documentation of pressure values in the maintenance
documentation.

10.5.7 Hydraulic fluid care

The hydraulic fluid should be analyzed at least annually.
For analyzing the hydraulic fluid a thorough hydraulic fluid sample must be taken.
The hydraulic fluid sample must be checked in a qualified laboratory according to the
applicable manufacturer's specifications for the hydraulic fluid.
Depending on the result, additional measures need to be taken. E.g.:
Measures:
• Additional filtering measures
• Dehydration
• Replacement
The use of treated and recycled hydraulic fluid (secondary raffinate hydraulic
fluid) is to be avoided.
For hydraulic fluid change, proceed as follows:
▶ Fully drain the hydraulic fluid. Refer to chapter 11.1 "Preparing for
decommissioning".
▶ In this connection, ensure complete draining of the lines and actuators.
▶ If necessary, carry out bleeding measures.
▶ Fill the system as for initial filling with subsequent bleeding of the hydraulic
system. See chapter 8.1.2 "Filling the hydraulic system".

10.5.8 Visual inspection for leakage, cracking, force effects and corrosion

External inspection is visual inspection and needs to be carried out at least semi-
annually (or more often depending on operating conditions and use).
Clean the system before visual inspection as necessary.
Visual inspection is carried out for:
• Leakage
• Cracking
• Corrosion
• Dents due to external force effects
