INSTALLATION
Pressure Relief Procedure
To reduce the risk of serious bodily injury, including fluid
injection, splashing in the eyes or on the skin, or injury
from moving parts, ALWAYS follow this procedure
whenever you shut off the pump, and before installing,
removing, cleaning or servicing any part of your sys-
tem.
1. Engage the gun’s safety latch.
2. Shut off the air to the pump.
3. Close the bleed–type master air valve (required in
your system).
4. Disengage the gun safety latch.
5. Hold a metal part of the gun firmly to the side of a
grounded metal pail, and trigger the gun to relieve
pressure.
6. Engage the gun safety latch.
7. Open the drain valve, having a container ready to
catch the drainage.
8. Leave the drain valve open until you are ready to
spray again.
If you suspect that the spray tip or hose is completely
clogged, or that pressure has not been fully relieved af-
ter following the steps above, VERY SLOWLY loosen
the tip guard retaining nut or hose end coupling and re-
lieve pressure gradually, then loosen completely. Now
clear the tip or hose.
WARNING
NOTE: Reference numbers and letters in parentheses
in the text refer to Figs. 1 and 2 and the Parts
Drawings.
Unscrew the plate retaining screws and remove the iden-
tification plate (A) and warning plate (C) from both sides
of the air motor. To avoid twisting the screw heads off if
the screws are hard to remove, tap lightly on the screw
heads with a hammer, then remove them.
Removing the Serial Plate
Using a side cutter, cut off the back of the rivets holding
the serial plate (B) to the identification plate (A) . Push out
the rivets with an awl or similar tool. See Fig. 1.
BE SURE to keep the serial plate and reinstall it on
the muffler as described on page 3. You cannot order
parts or request service or warranty information without
the serial plate information. Record the serial plate (B)
and identification plate (A) information on the front of this
manual as an added precaution. Keep the manual in a
safe place.
