WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure at left.

The packing nut is torqued at the factory and is ready for operation. If it becomes loose and there is leaking from the throat packings, relieve pressure, then tighten the nut as specified in your separate pump manual. Do this whenever necessary. Do not overtighten the packing nut.

2.Shut off the air supply to the pump.

3.Close the bleed-type master air valve (required in your system).

4.Unlock the gun trigger safety.

7.Open the drain valve (required in your system), having a container ready to catch the drainage.

8.Leave the drain valve open until you are ready to spray again.

If you suspect that the spray tip or hose is completely clogged, or that pressure has not been fully relieved after following the steps above, very slowly loosen the tip guard retaining nut or hose end coupling and relieve pressure gradually, then loosen completely. Now clear the tip or hose.

Flush the Pump Before First Use

Pumps are tested with lightweight oil which is left in to protect the pump parts. To prevent contamination of the fluid, flush the pump with a compatible solvent before using it.
