Pressure Relief Procedure
To reduce the risk of serious bodily injury, including
fluid injection, splashing fluid or solvent in the eyes or
on the skin, or injury from moving parts or electric
shock, follow this procedure whenever you shut off
the sprayer, when checking or servicing any part of
the spray system, when installing, cleaning or chang-
ing spray tips, and whenever you stop spraying.
1. Engage the gun safety latch.
2. Shut off the pump and unplug it (or disconnect the
spark plug).
3. Disengage the gun safety latch. Hold metal spray
extension firmly to the side of a grounded metal
pail, and trigger the gun to relieve pressure.
4. Engage the gun safety latch.
5. Open the sprayer’s pressure drain valve, having a
container ready to catch the drainage. Leave the
valve open until you are ready to spray again.
If you suspect that the spray tip or hose is com
-
pletely clogged, or that pressure has not been fully
relieved after following the steps above, VERY
SLOWLY loosen the tip retainer nut or hose end cou-
pling to relieve pressure gradually, then loosen com-
pletely. Now clear the tip or hose.

ity of explosion, which could cause death, serious bodily injury and/or substantial property damage.
