Operational Handling
5.1
Safety Warnings
Please pay special attention to the following safety warnings prior to taking this spray
gun into operation!
•
Wear proper respiratory protection masks and protective overalls, whenever you
are operating this spray gun. Air-borne particles represent a health hazard.
•
Make sure to wear suitable haering protectors. The gun produces sound levels
of up to 86 dB (A) which may cause hearing defects.
•
Open fires, naked lights and smoking prohibited in the working area. Spraying
of readily flammable media such as paints and adhesive compounds is always
accompanied by the risk of fire and explosion.
5.2
Starting / Stopping Requirements
The following requirements must be met before taking this spray gun into operation:
•
control air must be available at the gun.
•
atomizing air must be available at the gun.
•
material pressure must be available at the gun.
Attention
The material pressure shall not exceed
• 8 bar
, as, otherwise, the functional
reliabty of the spray gun will suffer.
Adjust the control air pressure to
• at least 4,5 bar
, in order to operate the spray
gun.
You can switch the spray gun on and off by actuating the customer supplied 3/2-way
pilot valve (see operating instructions of the system manufacturer).
Warning
It is important to remember that the spray gun must be relieved of all pressures
whenever work is terminated. Lines left in pressurized condition could burst, with
their contents likely to injure anybody present nearby.
5.3
Spray Pattern Test
Spray pattern tests should be performed whenever:
•
the spray gun is taken into operation for the first time.
•
the spraying medium is changed.
•
the spray gun was taken apart for servicing or repairs.
The spray pattern can be tested using a work piece sample, a sheet of metal, card-
board or paper.
Warning
Keep away from the front of the spray gun - imminent risk of injury.
Warning
Make sure that nobody is present in the spraying zone when the gun is started -
imminent Risk of Injury.
1. Start the gun to produce a spray pattern sample (see
5.2. Starting/Stopping
Requirements
).
2. Inspect the sample and readjust the settings of the gun as may be required (see
5.4 Spray Pattern Adjustments
).
5.4
Spray Pattern Adjustments
Note
Correct mixing of the spray jet is only achieved when both components flow evenly
or correctly metered to the gun.
The spray pattern of the PILOT Misch-Automatik can be adjusted as follows:
Adjusting the jet pattern
Adjustment of the material flow rate
Adjustment of the Material Pressure
This adjustment can only be made at the pump or the material pressure tank. Please
comply with the operating instructions and safety warnings issued by the manufac-
turers concerned.
Depending on the material pressure setting
more or less material will exit the nozzle.
The material quantity can be further regu-
lated by screwing the spring bushings
(item 12) in or out.
The regulating screw (Pos. 18) is used to
regulate the spraying width. By turning it to
the left (unscrewing), the spray becomes
wide, by turning it to the right (screwing
down) it becomes round.
