CAUTION
The
wallet sized warning card provided
with the gun
should be kept with the operator at all times. The
card
contains important information
on reducing the
risk
of
a fluid injection injury
, and treatment informa
-
tion should an injection injury occur. Additional co-
pies
of this card are available at no cost.
Pressure Relief Procedure
To
reduce the risk of serious bodily injury
, including
fluid injection, splashing in the eyes or on the skin,
injury from moving parts, or electric shock, always
follow this procedure whenever you shut off the
sprayer,
when
checking or servicing any part of the
spray
system, when installing, cleaning or changing
spray
tips, and whenever you stop spraying.
1.
Shut of
f the sprayer and unplug it.
2. Hold
a metal part of the gun firmly to
the side of
a grounded metal pail, and trigger the gun
into
the pail to relieve pressure.
3.
Engage the trigger safety lever
.
4. Turn the bypass valve counterclockwise one
turn
to drain paint back into the pail.
If
you suspect that
the spray tip or hose is complete
-
ly clogged, or that pressure has not been fully re-
lieved after following the steps above,
very slowly
loosen
the tip guard retaining nut or hose end cou
-
pling and relieve pressure gradually, then loosen
completely.
Now clear the tip or hose obstruction.
WARNING
1. Open the bypass valve ONE turn counterclock-
wise. Do not place the pump intake in the pail yet.
See
Fig 3.
2. Turn
the pressure control fully
clockwise
to
increase
pressure.
See Fig 3.
3.
Remove the inlet strainer and place your hand over
the inlet valve to be sure it is drawing a vacuum.
NOTE: If
the inlet valve is not drawing a vacuum, turn the
sprayer
OFF
. T
urn the sprayer over
. Press down
on the stem inside the inlet valve lightly with a
small
screwdriver
, and pour about a teaspoon
of
mineral
spirits or solvent
into the valve. See Fig
4. Release the valve and turn the sprayer up-
right. With the pressure turned up, turn on the
sprayer.
This should free
any sticking parts in the
pump. Now check again for a vacuum. Shut off
the
sprayer and install the inlet strainer
.
4. Place the paint pump assembly into a properly pre-
pared
5 gallon pail of paint. (See Step 1, page 10.)
5. Turn
the sprayer ON and
allow the paint to circulate
through
the bypass valve for one or two minutes.
NOTE: If the paint does not circulate back into the pail,
turn down the pressure and “jog” the motor on
and
of
f several times to help prime the sprayer
.
6. Turn the bypass valve clockwise (finger tight) to
close
it; this allows the pump to build up pressure.
