We would like to point out that the valid guidelines and stipulations depending
on the work environment (mining, closed rooms, etc.) must be respected in
any case.
➤
Always wear the protective clothes specified by the material manufacturer to
avoid injuries.
➤
It is recommended that the operator should always wear a respiratory protec
-
tion mask, even though the paint mist has been minimized in Airless spray
painting applications with correct pressure setting and working mode.
➤
Wear protective goggles to protect against eye injuries caused by mechanical
or chemical influences.
➤
Wear protective gloves with lower arm protection to avoid burn injuries.
➤
The sound pressure level of this unit is less than 85 db(A).
However, operating personnel should still be provided with suitable noise
protection equipment.
All units are delivered with the following safety features:
Master switch,
(Figure 2.3)
When the master switch on the control cabinet is switched to position “0 / OFF”
both the electric power and compressed air supplied are immediately cut off.
Note:
➤
The compressed air supply to the spray is not interrupted!
➤
Material may still be under pressure in the system!
Safety valve,
(Figure 2.4)
The safety valve on the air motor of the metering pump makes sure that the max.
permissible air inlet pressure is not exceeded. The safety valve will open and vent
off air when the air inlet pressure exceeds the set limiting value.
Overtemperature switch,
(not shown)
These elements switch off the equipment when the maximum permissible tem
-
perature in the material flow heaters is exceeded. This malfunction is signalized
on the control cabinet.
After the material flow heater has cooled down and the malfunction has been
acknowledged, the plant can be operated again.
Material pressure relief valves,
(not shown)
In the factory both pressure relief valves were set to the maximum admissible
operating pressure. When this value is exceeded the equipment, including the
heaters, will switch off completely.
This malfunction is signalized on the control cabinet.
Trouble free operation can only be resumed after the pressure on the correspond
-
ing components has been relieved.
Air pressure valve on the spray gun,
(Figure 2.5.)
The air pressure valve must be locked for each break, even for short interruptions
of work. Slide the air valve to position “CLOSED
/
0” to do so.
With missing compressed air the material valves will stay closed.
