2. Turn off the air bleed valves to the fluid source and
to the gun.
3. Unlock the gun trigger.
4. Trigger the gun into a grounded metal waste con-
tainer to relieve the fluid pressure.
5. Lock the trigger.
6. Open the drain valve on the fluid filter and all other
fluid drain valves in the system, having a waste con-
tainer ready to catch the drainage. Leave the drain
valve(s) open until you are ready to spray again.
7. If the nozzle or hose is completely clogged or pres-
sure is not fully relieved, slowly loosen the hose end
coupling. Now clear the nozzle or hose.
Flush the Pump Before First Use
The pump is tested with lightweight oil, which is left in to
protect the pump parts. If the fluid you are using may be
contaminated by the oil, flush it out with a compatible
solvent before using the pump. See Flush the Equip-
ment on page 11.
