If spray material does not flow from the return tube,
the inlet valve may be stuck. Follow these steps.
1. Shut the unit OFF and unplug.
2. Carefullyremovethehopper.Cleantheconnectionarea

The spray tip should not be attached to your spray gun
when purging your spray hose.
2. PULLthetriggerandaimthespraygunatthesidewallofa
wastecontainer.Ifusingoil-basedmaterials,thespraygun
must be grounded while purging (see warning below).
Danger
Keep hands clear from fluid stream. Ground the gun
by holding it against the edge of a metal container
while flushing. Failure to do so may lead to a static
electric discharge which may cause a fire.
3. Whilepullingthetrigger,switchthepumpON(l),andturnthe

Danger
If the PRIME/SPRAY knob is still on SPRAY, there will
be high pressure in the hose and spray gun until the
PRIME/SPRAY knob is turned to PRIME.

Figure12-AttachingtheSprayTip
Danger
POSSIBLE INJECTION HAZARD. Do not spray
without the tip guard in place. Never trigger the
gun unless the tip is in either the spray or the unclog
position. Always engage the gun trigger lock before
removing, replacing or cleaning tip.
1. Lockthespraygunoff.
2. Thread the tip guard onto the gun.
i
When attaching the tip guard to the gun, align the tip
guard as shown in figure 12 (a), then tighten by hand
(b).

When finished spraying, perform Pressure Relief
Procedure.
i
If you expect to be away from your spray project for
more than 1 hour, follow the Short Term Cleanup
procedure described in the Cleanup section of this
manual.
Figure 14 - Practice
1. Be sure that the paint hose is free of kinks and clear of objects
with sharp cutting edges.
2a. Ifyouaresprayingthickermaterials,turnthePRIME/SPRAY

2b. Ifyouaresprayingthinnerorlighterbodiedmaterials,turnthe
PRIME/SPRAY knob to SPRAY (1).
i
The paint hose should stiffen as material begins to flow
through it.
3. Unlockthespraygun.
4. While pointing the gun at a piece of scrap wood or cardboard,
triggerthesprayguntobleedairoutofthehose.

6. Usethelowestpressuresettingnecessarytogetagoodspray
pattern(A).Ifthepressureissettoohigh,thespraypattern
will be too light. If the pressure is set too low, tailing will
appear or the paint will spatter out in blobs rather than in a
finespray(B).
Figure15-UncloggingtheSprayTip
i
If the spray pattern becomes distorted or stops
completely while the gun is triggered, follow these
steps.
Danger
Do not attempt to unclog or clean the tip with your
finger. High pressure fluid can cause injection injury.
1. Release the trigger and lock the gun off. Rotate the reversible
tip arrow 180º so that the point of the arrow is toward the rear
of the gun (see figure 15).
