Operation - Graco EM 5000 Instructions-Parts List Manual

WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 6.
1. Prime the Sprayer with Paint.
a. Close the pressure drain valve (C). See Fig. 3.
b. Don't install the spray tip yet!
c. Put the suction tube (D) into the paint container.
d. Turn the pressure adjusting knob (B) all the way
counterclockwise to lower the pressure setting.
e. Disengage the gun safety latch (E).
f. Hold a metal part of the gun firmly against, and
aimed into, a grounded metal waste container.
See Fig. 4. Squeeze the trigger and hold it open.
Turn the ON/OFF switch (A) to ON. See Fig 8–1.
Slowly increase the pressure setting until the
sprayer starts. Keep the gun triggered until all air
is forced out of the system and the paint flows
freely from the gun. Release the trigger and en-
gage the gun safety latch.
NOTE: If the pump is hard to prime, open the pressure
drain valve (C). When fluid comes from the
valve, close it. Disengage the gun safety and
proceed as in Step 1f, above.
g. Check all fluid connections for leaks. If any leaks
are found, relieve the pressure before tighten-
ing connections.
2. Install the Spray Tip and Tip Guard
a. Be sure the gun safety latch is engaged.
b. Install the spray tip. If you are using the RAC IV
tip guard, refer to manual 307–848, supplied with
the gun, for installation instructions.
