WARNING
If untrained personnel carry out maintenance and repair work, they
endanger themselves and others, and risk the operational safety of the
device.
➤
Maintenance and repair work on electrical parts may only be
performed by specialist personnel with electrical
qualifications — all other maintenance and repair work may
only be performed by
WIWA
customer service or specially
trained personnel.
WARNING
During maintenance work, ignition sources may develop
(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 operation manual for the
optional accessories.
Prior to maintenance and repair work:
1.
Shut off the compressed air supply.
2.
Completely relieve the pressure in the device.
WARNING
If parts of the device are clogged, it is not possible to fully relieve the
pressure. During disassembly work, residual pressure may 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 on page 37).
After completion of the maintenance and repair work, check the function
of all safety features and faultless function of the device.
