SPRAYING
5.The spray gun should be triggered off at the end of each stroke and on again at the beginning of the next. This avoids paint buildup at the end of the stroke which may result in runs and sags. Triggering at the end of the stroke also saves paint and results in a better looking job. See Figure 28.

Figure 28 - Proper Way to Trigger Spray Gun
6.Overlap each stroke by about 30%. This will assure a paint coating that is uniform across the work. One way to do this is to point the spray tip at the edge of the last stroke before triggering the gun on.
7.When taking a short break from painting (up to 1 hr.), lock the spray gun trigger OFF, reduce pressure to its minimum (zero) setting and set the unit to prime A . Turn sprayer off and unplug. Refer to Pressure Relief Procedure.
8.If you expect to be gone more than 1 hour follow the short term clean up procedure.
If Spray Tip Becomes Clogged
The spray gun is equipped with a reversible tip which enables you to quickly and effectively blow out any particles of old paint or other contaminants that may obstruct the paint flow through the tip. If the spray pattern becomes distorted or stops completely while the gun is triggered on, follow these steps.
1.Release the trigger and put on the safety lock. See Figure 4.
2.Rotate the reversible tip cylinder arrow 180° so the point of the arrow is toward the rear of the gun. Figure 29.
Figure 29 - Reverse Tip
3.Unlock the trigger and squeeze it open, pointing the gun at a scrap piece of wood or cardboard. This allows pressure in the paint hose to blow out the obstruction. When the nozzle is clean, paint will come out in a straight, high pressure stream.
4.Release the trigger and
5.Reverse the tip so the arrow points forward again.
6.Unlock the trigger and resume spraying.
