Setup
Pressure Relief Procedure
To reduce the risk of serious bodily injury, including
fluid injection, splashing fluid or solvent in the eyes
or on the skin, or injury from moving parts or elec-
tric shock, always follow this procedure when you
shut off the sprayer, check or service any part of
the spray system, install, clean or change spray
tips, and whenever you stop spraying.
1. Engage the gun safety latch.
2. Turn the ON/OFF switch to OFF.
3. Unplug the sprayer.
4. Disengage the gun safety latch. Hold a metal
part of the gun firmly to the side of a grounded
metal pail. Trigger the gun to relieve pressure.
5. Engage the gun safety latch.
6. Open the pressure drain valve. Leave it open
until you are ready to spray again.
If you suspect that the spray tip or hose is com
-
pletely clogged, or that pressure has not been fully
relieved after following the steps above, VERY
SLOWLY loosen the tip guard retaining nut or hose
coupling to relieve pressure gradually, then loosen
completely.

WARNING
To reduce the risk of serious bodily injury from fluid
injection:
NEVER operate the spray gun with the tip guard
removed.
DO NOT hold your hand, body, or a rag in front of
the spray tip when cleaning or checking a clogged
tip. Always point the gun toward the ground or into
a pail when checking to see if the tip is clear.
DO NOT try to “blow back” paint; this is NOT an air
spray sprayer.
The tip guard alerts you to the risk and helps prevent
placing any part of the body close to the spray tip. The
tip guard also adjusts the vertical or horizontal spray
pattern. See page 13. The tip guard holds a reversing
spray tip. The tip is in the spraying position when the
tip handle points forward. See Fig. 5.
Clean the front of the tip frequently during the day’s
operation. First, follow the
