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.
Figure 1
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 muffler strainer
felt (59) or replace, if necessary.
