SAFETY CHECKS
WAGNER recommends having all spraying devices checked annually by a technical expert (e.g., a WAGNER
service technician) for safety reasons.
8.2.3.1
GROUNDING CHECK
Daily
Before starting work, carry out a visual check to ensure that the grounding connection is present in the
device and in all relevant components.
8.2.3.2
PRODUCT HOSES, TUBES AND COUPLINGS
Bursting hose, bursting threaded joints!
Danger to life from injection of product and from fl ying parts.
The service life of the complete hoses between product pressure generator and application device is reduced
due to environmental infl uences even when handled correctly.
Check hoses, pipes, and couplings every day and replace if necessary.
Before every commissioning, check all connections for leaks.
Additionally, the operator must regularly check the complete hoses for wear and tear as well as for
damage at intervals that he/she has set. Records of these checks must be kept.
The complete hose is to be replaced as soon as one of the two following intervals has been exceeded:
– 6 years from the date of the hose crimping (see fi tting embossing).
– 10 years from the date of the hose imprinting.
