Pressure Relief Procedure
Follow the Pressure Relief Procedure
whenever you see this symbol.
1. Engage the gun trigger lock.
2. XP Systems:
Close the main air shutoff valve (MA).
XP-h Systems:
Set pump valve off.
3. Shut off heaters, if used.
4. Shut off feed pumps, if used.
5. Remove the spray tip.
6. Disengage the trigger lock.
7. Hold a metal part of the gun firmly to a grounded
metal pail. Trigger the gun to relieve pressure.
8. Engage the gun trigger lock.
9. Close the dual shutoff handle (FE) and open the
circulation handle (FC) to relieve A and B fluid
pressure.
10. Always flush the mix hose after relieving A and B
fluid pressure through the mix manifold. Follow
Flush Mixed Material, page 37 when you stop
spraying or dispensing; and before cleaning,
checking, servicing, or transporting equipment.
11. If you suspect the spray tip or hose is clogged or
that pressure has not been fully relieved after
following the steps above, very slowly loosen tip
guard retaining nut or hose end coupling to relieve
pressure gradually, then loosen completely. Clear
hose or tip obstruction.
12. If static mixer, whip hose, and gun cannot be
flushed because of mixed and cured material, very
slowly loosen static mixer tube from mix manifold
outlet to relieve pressure gradually, then loosen
completely. Replace or clean clogged components.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing fluid
and moving parts, follow the Pressure Relief
Procedure when you stop spraying and before
cleaning, checking, or servicing the equipment.
