SAFE HANDLING OF WAGNER SPRAY DEVICES
4.2.2
GROUNDING THE DEVICE
The spray jet is under pressure and can cuse dangerous injuries.
Avoid injection of paint or cleaning agents:
Never point the spray gun at people.
Never reach into the spray jet.
Before all work on the device, in the event of work interruptions and functional faults:
– Switch off the energy/compressed air supply.
– Relieve the pressure from the spray gun and device.
– Secure the spray gun against actuation.
– In the event of functional faults: remedy the fault as described in the "Troubleshooting"
chapter.
The liquid ejection devices are to be checked for safe working conditions by an expert
(e.g. Wagner Service Technician) as often as necessary or at least every 12 months,
in accordance with the guidelines for liquid emitters (ZH 1/406 and BGR 500 Part 2
Chapter 2.36).
– For shut down devices, the examination can be suspended until the next commissioning.
Carry out the work steps as described in the "Pressure Relief/Work Interruptions" chapter:
– if pressure relief is required.
– if the spraying work is interrupted or stopped.
– before the device is cleaned on the outside, checked, or serviced.
– before the spray nozzle is installed or cleaned.
In the event of skin injuries caused by paint or cleaning agents:
Note down the paint or cleaning agent that you have been using.
Consult a doctor immediately.
Avoid danger of injury through recoil forces:
Ensure that you have firm footing when operating the spray gun.
Only hold the spray gun briefl y in a position.
Depending on the high-voltage on the spray electrode and the fl ow speed during spraying,
an electrostatic charge may occur in the device. This may result in the formation of sparks
or fl ames when discharging.
Ensure that the device is grounded at all times.
Ground the work pieces to be coated.
Ensure that all persons inside the working area are grounded, e.g. that they are wearing
static dissipative shoes.
Wear static dissipative gloves for grounding via the spray gun handle when spraying.
