• Cleaning. See g 9.3 Cleaning
• Maintenance. See g 9.4 Maintenance
9.1 Notes on safety
To eliminate risks during service, observe the notes on safety. See g 2. Safety.
9.2 Inspection
During inspection, check the product for damage and contamination at regular
intervals.
9.2.1 General requirements
Use in normal ambient conditions
• Inspection interval: The product must be checked monthly.
• The operator is responsible for inspection of the product and the overall sys-
tem.
Use in aggressive ambient conditions
Aggressive ambient conditions include, for example:
• High temperatures
• Heavy accumulation of dirt
• Proximity to grease-dissolving liquids or vapors
Aggressive ambient conditions lead to further requirements for inspection:
• Adapt the inspection interval for seals to the ambient conditions.
NOTICE! Seals age faster under aggressive ambient conditions. Defective
seals will lead to pneumatic leaks and non-compliance with the degree of pro-
tection. Inspect seals more frequently (material protection).
• Enter the adapted inspection intervals in the system-specific maintenance
plan (accident prevention, material protection).
9.2.2 Procedure
Preparation
All work has to be prepared as follows:
1. Close off dangerous areas (accident prevention).
2. Make sure the system or system part is not under pressure or voltage (acci-
dent prevention, material protection).
3. Protect the system against being restarted (accident prevention).
4. Allow the product and adjacent system parts to cool down (accident preven-
tion).
5. Wear protective clothing (accident prevention).
Visual inspection
Visually inspect for integrity.
Detailed inspection
• Check identifications and warnings on the product: Labels and identifications
must be legible (accident prevention, material protection).
Replace hard-to-read labels or identification immediately.
• Check to make sure that all fittings are properly connected.
• Check the safety devices on the system.
• Check the product functions.
9.3 Cleaning
9.3.1 General requirements
Cleaning intervals
• The system owner specifies the cleaning intervals in line with the ambient
conditions at the operating site.
• Observe the information in the system documentation.
Aids
• Only clean the product with damp cloths.
• Only use water for cleaning and a mild detergent, if necessary (material pro-
tection).

Notes
• Penetrating fluids destroy seals and cause damage to the product (material
protection).
• Make sure that water and water mist cannot enter the product via the com-
pressed air connections (material protection).
9.3.2 Procedure
Preparation
All work has to be prepared as follows:
1. Close off dangerous areas (accident prevention).
2. Make sure the system or system part is not under pressure or voltage (acci-
dent prevention, material protection).
3. Protect the system against being restarted (accident prevention).
4. Allow the product and adjacent system parts to cool down (accident preven-
tion).
5. Wear protective clothing (accident prevention).
6. Close all openings with suitable safety devices so that no cleaning agent can
enter into the system.
Cleaning
1. Remove all dust deposits from the product and the adjacent system parts.
2. If necessary, remove other production-related deposits from the product and
the adjacent system parts.
9.4 Maintenance
Notes
• Observe the maintenance plan for the overall system: Further maintenance
tasks may result from the maintenance plan for the overall system and the
maintenance intervals specified therein.
• The filter element becomes clogged over time and must be replaced regu-
larly, at the latest after one year.
• Adapt the maintenance interval to the ambient conditions.
• No soiling may be allowed to collect on or in the filters, bowls or windows. Re-
place bowls if soiling cannot be removed from the drain. The drain may other-
wise become clogged.
9.5 After service
After completion of the service work, carry out the following steps:
1. Remove all tools and devices from the work area.
2. Remove all installed barriers and notices.
3. Clean the work area, mop up any liquids and remove work materials.
4. Log any service work in the respective plan.
If no damage has been detected and the operator has not reported any malfunc-
tions, the product can be reconnected to the power supply and put back into op-
eration.
10 Dismounting
Disassembly is only required if the product has to be exchanged, installed in a dif-
ferent location or disposed off.
10.1 Basic requirements
• Make sure that there is sufficient space.
• Secure larger product or system parts so that they cannot fall down or topple
(accident prevention).
• Do not stand under suspended loads (accident prevention).
• Make sure that the environment is not contaminated with grease or lubricants
during disassembly (material protection).
10.2 Notes on safety
To eliminate risks during disassembly, observe the notes on safety. See
g 2. Safety.
10.3 Preparation
1. Close off dangerous areas (accident prevention).
