WARNING
If untrained personnel carry out maintenance and repair work, they endanger
themselves and others, as well as risking the operational safety of the
machine.
➤
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.
For proportioning pumps that are supplied with material via a hopper, pump
out the material that is still located in the hoppers completely.
2.
Shut off the compressed air supply.
3.
Completely de-pressurize the machine.
WARNING
Despite relieving the pressure, residual pressures can still be present due
to material congestion or clumping which can suddenly escape during
disassembly work and cause serious injuries.
➤
You must be particularly careful during disassembly work!
➤
When disassembling material hoses, cover the screw connection with
a cloth in order to catch possible material sprays.
After completion of the maintenance and repair work, check the function of all
safety features and the faultless function of the machine.
6.1 Regular testing
The machine must be inspected and maintained by a specialist:
➤
prior to first commissioning,
➤
after changes to / the servicing of parts of the installation that affect safety,
➤
after an interruption to operation lasting more than 6 months,
➤
although at least every 12 months.
In the case of machines that have been put out of use, the test can be delayed
until the next time commissioning takes place.
