Installation/Operation
How to Check the Gun Diffuser Operation
Check the diffuser operation weekly. The gun diffuser/ seat (2a) breaks up spray and reduces the risk of fluid injection when the tip is not installed. Perform the test below. If it fails, replace the entire Needle Kit, Part No.
WARNING
To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 5.
1.Follow the Pressure Relief Procedure, page 5.
2.Remove the tip guard and spray tip.
3.Start the sprayer and adjust it to the lowest pressure.
4.Aim the gun into a grounded metal pail while holding it firmly to the pail. Trigger the gun. If the fluid emitted is not diffused into an irregular stream, replace the entire needle kit immediately. See Fig. 5.
