1. Unscrew caps nr. 11 and valve bodies nr. 12.
2. Fill the pump hydraulic circuit with working fl uid.
3. Completely close the pump air pressure reducer and open
the motor air shut-off valve (parts C and D, diagram in
Paragraph 5.1.6).
4. Paying great attention to squirts, slowly open the air
pressure reducer and run one/two cycles of the pneumatic
motor. Then close the pressure controller. This operation
allows emptying the residual air in the hollows of the
hydraulic circuit.
5. Refi ll the hydraulic circuit with working fl uid.
6. Remount valves nr. 12.
7. Run the pump for about one minute, collecting the excess
hydraulic fl uid discharged by valves nr. 12 in the previously
used container.
8. Remount caps nr. 11 and the rest of the pump.
6.3.1.1
OPERATIONS ON THE HYDRAULIC CIRCUIT DURING MAINTENANCE
• If the pump is subject to maintenance regarding the fl uid section not implying disassem-
bling the diaphragm covers (parts °16 given in the diagram in Paragraph 8.5), the hydraulic
circuit system does not undergo any particular changes and the following operations are
not necessary.
• If the maintenance in the fl uid section concerns components whose access to or di-
sassembly of require disassembling the pump covers (diagram Paragraph 8.5), then the
following operations to empty and fi ll up the hydraulic circuit with working fl uid are ne-
cessary.
• If the maintenance concerns the pneumatic motor or the hydraulic circuit itself, the fol-
lowing operations are necessary.
WARNING: the best possible performance of the vacuum system inside the hydraulic circuit
is important to guarantee the longest possible life of the membranes. The following opera-
tions are hence to be carried out only by Wagner authorised engineers.
6.3.1.2
HYDRAULIC CIRCUIT EMPTYING
Referring to the assemblying diagram in Paragraph 8.4:
1. Get a container to collect the hydraulic fl uid and place it under the pump.
2. Disconnect pipe nr. 17 from quick coupling nr. 10 and extract the hydraulic fl uid
collecting it in the dedicated container. Dispose of the fl uid in compliance with the
local law regulation.
6.3.1.3
HYDRAULIC CIRCUIT FILLING
After maintenance, remount the various pump sections except the outer protections (parts
3 and 4 in the diagram in Paragraph 8.2), connect the pump to the compressed air supply
line, see diagram given in Paragraph 8.4 and proceed as follows:
