WARNING
If untrained personnel carry out maintenance and repair work, they endan-
ger themselves and others, as well as risking the operational safety of the
machine.
➤
Maintenance and repair work on electrical parts must be carried out by
specialist personnel with an electrical qualification – all other mainte-
nance and repair work must be carried out by
WIWA
customer service or
specially trained personnel.
WARNING
During maintenance work ignition sources may arise (e.g. due to mechanical
sparks, electrostatic discharge, etc.).
➤
Carry out all maintenance work outside of potentially explosive areas.
Observe the maintenance information in the operating instructions for the
optional accessories.
Prior to maintenance and repair work:
1.
Shut off the compressed air supply.
2.
Disconnect the electrical power supply.
3.
Depressurise the machine completely.
WARNING
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 may escape and cause serious injuries.
➤
Protect yourself against the sudden emergence of material by covering
threaded connections with a cloth whilst loosening.
➤
Loosen threaded connections particularly cautiously and allow the pres-
sure to escape slowly.
➤
Eliminate the blockages (see fault table in Chap. 7 on page 43).
After completing maintenance and repair work, check the function of all safety
devices and the faultless function of the machine.
