Operation

5.1

Safety Instructions

Please pay special attention to the following safety instructions when using the spray
gun!
• Be sure to wear the required respiratory protection masks and protective over-
alls whenever you are operating the spray gun. Airborne particles represent a
health hazard.
• Be sure to wear suitable ear protection. The spray gun produces sound levels
of approx. 85 dB (A).
• No open fires, naked lights or smoking in the working area. The spraying of
readily inflammable media (e.g. varnish, adhesives etc.) is accompanied by an
increased risk of fire and explosion.
5.2

Requirements at the Start and Finish of Operation

The following requirements must be met before the spray gun is operated:
• The atomising air pressure must be available at the gun
• The material pressure must be available at the gun (not applicable with gravity
feed cups, pressure feed cups).
32
Caution
The material pressure should not exceed 8 bar (except PILOT XIII-HD). The air
pressure should not exceed 8 bar, since otherwise the operational reliability of the
spray gun will be impaired. The material pressure in the cup should not exceed 3 bar.
Warning
It is important to remember to relieve the spray gun of all pressures when work is
terminated. Lines left under pressure may burst and the released material may
injure any persons in the vicinity.
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 maintenance or repair works.
The spray pattern is best tested using a workpiece sample, a sheet of metal, card-
board or paper.
Warning
Keep your hands or other parts of the body away from the front of the spray gun
- imminent risk of injury.
Warning
Make sure that no other people are in the spraying zone when the spray gun is
started - imminent risk of injury.
1. Start the gun to produce a spray pattern sample (see 5.2 Requirements at the
Start and Finish of Operation).
2. Inspect the sample and, if necessary, adjust the settings of the gun (see 5.4

Spray Pattern Adjustment).

5.4 Spray Pattern Adjustment
The spray pattern of the PILOT XIII / the PILOT XIII-D / PILOT XIII-HVLP and the
PILOT XIII-HD can be adjusted as follows:
Round or Flat Jet
The adjusting screw (Item 15) is used to regulate the spray jet contour.
By turning the screw to the left (screwing out) the jet becomes flat, by turning it to the
right (screwing in) it becomes round. This function is not applicable at PILOT XIII-D.
Adjusting the Material Flow Rate
The material flow rate can be adjusted at the regulating screw (Item 21). Turning it
to the left (screwing out) results in an increase of material, turning it to the right
(screwing in) decreases the material flow.
