Operation
5.4 Material change
1.
Flush the machine as described in chapter 5.3 ‘Flushing’ on
page 36.
2.
Let the machine run to empty by taking the suction out of the
cleaning agent and triggering the spray gun until air escapes.
3.
Close and lock the gun.
4.
Completely reduce the air inlet pressure (0 bar).
5.
Relieve the pressure in the device (see 5.5 ‘Relieving the
pressure’ on page 38).
6.
Check the filter element in the high pressure filter (see 6.4.1
‘Cleaning the filter element’ on page 43).
7.
After completing the work, spraying may begin with a new
material (see chap. 5.2 ‘Spraying’ on page 34).
5.5 Relieving the pressure
1.
Close the compressed air shut-off valve.
The machine vents automatically.
2.
Hold the relief hose in the collecting vessel.
3.
Briefly open the relief valve to relieve the pressure.
4.
Trigger the gun until all pressure has escaped.
Lock the gun.
CAUTION
If parts of the machine are blocked (e.g. spray nozzle, material
filter for the spray gun, material hose, high pressure filter, suction
screen, etc.), it is not possible to fully relieve the pressure. During
disassembly work, residual pressures can escape and cause
serious injuries.
➤
Protect yourself against suddenly ejecting material by
covering threaded connections with a cloth while loosening
them.
➤
Loosen threaded connections particularly cautiously and
allow the pressure to escape slowly.
➤
Remove the blockages (see fault table in chap. 7 ‘Eliminating
operational faults’ on page 46).
