2. Shut off the pump. See your pump manual.
3. Shut off the gun air supply.
4. Disengage the trigger lock. See FIG. 13.
5. Hold a metal part of the gun firmly to a grounded
metal pail. Trigger the gun to relieve pressure. See
FIG. 12.
6. Open all fluid drain valves in the system, having a
waste container ready to catch drainage. Leave
drain valve(s) open until you are ready to spray
again.
7. Engage the trigger lock. See FIG. 13.
8. If you suspect the spray tip or hose is clogged or
that pressure has not been fully relieved after follow-
ing the steps above, VERY SLOWLY loosen the tip
guard retaining ring or hose end coupling to relieve
pressure gradually, then loosen completely. Clear
hose or tip obstruction.

Trigger Lock

Always engage the trigger lock when you stop spraying
to prevent the gun from being triggered accidentally by
hand or if dropped or bumped.
SKIN INJECTION HAZARD
Remember, this is not an air spray gun. For your
safety be sure to read and follow the Warnings on
pages 4 and 5 and throughout the text of this instruc-
tion manual.
Keep the wallet sized warning card (222385), pro-
vided with the gun, with the operator of this equip-
ment at all times. The card contains important
treatment information should an injection injury occur.
Additional cards are available at no charge from
Graco.
SKIN INJECTION HAZARD
The system pressure must be manually relieved to
prevent the system from starting or spraying acciden-
tally. Fluid under high pressure can be injected
through the skin and cause serious injury. To reduce
the risk of an injury from injection, splashing fluid, or
moving parts, follow the Pressure Relief Procedure
whenever you:
• are instructed to relieve the pressure,
• stop spraying,
• check or service any of the system equipment,
• or install or clean the spray tip.
Follow Pressure Relief Procedure on page 10 when
you stop spraying and before cleaning, checking, ser-
vicing, or transporting equipment. Read Warnings,
page 4.
