SAFETY PRECAUTIONS
This manual contains information that is important
for
you
to
know
and
understand. This information relates to
USER
SAFETY and
PREVENTING EQUIPMENT PROBLEMS.
To
help you recognize this information,
we
use the following symbols. Please pay particular attention
to
these
sections.
Important information
that
tells
how
to
pre-
vent
damage
to
equipment, or
how
to avoid
a situation
that
may
cause
minor injury.
INSTALLATION (Continued)
3. Pour material into
the
tank.
See
acces-
sories
for
disposable tank liners. A one
gallon container may also
be
used by
cutting
3/16"
off
end
of
fluid tube at
an
angle.
4. Replace the lid assembly
and
tighten
clamps and
thumb
screws securely.
5. If possible, the air supply line should
pass through
an
air filter/regulator to
filter
dirt
from air
and
remove entrained
water and oil.
See
Accessories for
filters available. Connect the air supply
hose
to
the air inlet
fitting
on
tank
regulator.
6. Connect the atomization air hose
to
the
air outlet
fitting
which
is directly oppo-
site air inlet fitting.
7. Connect material hose
to
the fluid outlet
fitting.
8.
See
Figure 1
for
a typical hookup.
Note
See
Pg.
4 tor air and fluid
hook~up
information
on
the tank.

OPERATION
1. Turn on the air supply.
2. Turn T-Handle adjusting screw clock-
wise on the tahk regulator
to
increase
material pressure: turn
it
counter clock-
wise to decrease pressure. Maximum
tank pressure
is
80
PSI.
3. For tank
with
air
motor
agitator, turn the
knob
of
the
air adjusting valve
(9)
coun-
terclockwise
to
set the desired agitator
speed. Operate the agitator at the
m·lni-
mum speed required
to
keep the mate-
rial thoroughly mixed.
Do
not over-
agitate
the
materia!. Air bubbles may
form in the material, causing a poor
finish.
WARNING
I
Important
safety
information
~
A hazard
that
may
cause
serious
injury or loss of life.
4. Atomization air
for
the spray gun
can
be
adjusted at the gun by means of
an
air
adjusting valve (P-H-5516} or,
with
the
additional air regulator provided
with
"dual regulation"
tank
models (PT-511-
WB
or PT-521-WBI.
5.
See
Spray Gun instructions
for
operation
of the gun.
If
using
an
air quick disconnect
(0.0.)
at
the
inlet
to
the regulator at
the pressure tank, do
not
discon-
nect the O.D. while the tank is
pressurized, unless
the
ball valve is
closed. Doing
so
will allow tank
pressure
to
quickly relieve, and can
potentially pull paint back through
the air regulator and air motor, de-
pending upon
the
liquid level in the
tank. Tank pressure should always
be
relieved
by
turning the regulator
fully counterclockwise, or pulling
the safety valve ring.
REPLACEMENT
OF
PARTS
(Air
Motor
Assembly, See Page
5)
Do
not
pry
front
plate (39) or end plate (45}
from air
motor
body (42}
with
a screwdriver;
this will dent the surface
of
the plates
and
body causing leaks. A puller tool should
be
used
to
remove
the
plate from the motor
body while maintaining the position of the
shaft. Holes
must
be
drilled for dowel pins
(41)
after
assembling
front
plate (39)
on
new
body (42)
for
alignment of parts. Always
install
new
end plate gaskets (40) when
re-
assembling air motor.
PREVENTIVE MAINTENANCE
To Clean Equipment:
1. If
tank
is equipped
with
agitator, turn
off
air
to
agitator first. This will prevent the
possibllity
of
paint contamination
of
the
agitator air motor.
2. Turn
off
the main air supply
to
the tank.
Note
information
that
you should pay special
attention to.
3.
Turn T-handle adjusting screw
on
tank
regulator
counterclockwise
until no
spring tension is felt.
4. Relieve all pressure from the tank by
pulling
the
ring
on
the safety valve until
the pressure bleeds
down.
5. Loosen
thumb
screws, tip
damps
back
and tip
tank
lid to one side.
6.
Loosen spray gun air
cap
retaining ring
about three turns.
7. Turn on the air supply to spray gun.
8. Place cloth over air cap
on
the gun and
pull trigger. This will force material back
through
the
hose, into the tank.
9. Empty and clean tank
and
parts which
come in contact
with
material.
Use
a
suitable cleaning materiaL
10. Pour cleaning material into the tank.
11. Replace
l.id
and
tighten thumb screws
and clamps.
12. Spray until clean solution appears.
13. Repeat steps 5 through 8.
Keep the safety valve clean at
all
times.
Air
Motor
Assembly
Failure
to
properly lubricate the air
motor
will
result in premature mo-
tor
failure and will void warranty.
Lubricate air
motor
daily
by
adding
4 or 5 drops
of
SAE
10
weight oil
into air inlet
fitting.
Clean the agitator shaft (53,
Pg.
5)
and
the
propeller (55) at the
end
of
each
day. Occa-
sionally remove and clean the mufflerstrainer
felt (59) or replace,
if
necessary.
