elbow and fitting; 303 S.S. - Agitator shaft

PT-427 AIR MOTOR DRIVEN AGITATOR
The agitator utilizes an air driven motor to
turn the agitator shaft to which a propeller is
attached. The rotation of the propeller mixes
materials which have a tendency to separate
or settle quickly. Material agitation may be
performed at the same time material is being
sprayed without any adverse effect. The air
motor is powerful and smooth running. An
air adjusting valve is included to control the
speed of the agitator. The air motor requires
low air consumption, approximately 3-6
C.F.M. at 60 P.S.l. (Max. input air pressure
100 P.S.l.)
INSTALLATION
Mix and prepare material to be used accord-
ing to manufacturer's instructions. Strain
material through a fine mesh screen (60 or
90 mesh) to remove all foreign matter which
is likely to enter and clog material passages.
1 .
AIways relieve all air pressure in the
tank. Pull the ring on the safety valve
until pressure bleeds down.
2 .
Loosen thumb screws, tip lid clamps
back and remove lid assembly.
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 out-
let fitting.
8 .
See Figure 1 for a typical hookup.
Note
See Pg. 4 for 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 tank 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 (8) coun-
terclockwise to set the desired agitator
speed. Operate the agitator at the mini-
mum speed required to keep the mate-
rial thoroughly mixed. Do not over-
agitate the material. Air bubbles may
form in the material, causing a poor
finish.
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 (83Z-220
or 83Z-221-WB).
5 . See Spray Gun instructions for opera-
tion of the gun.
If using an air quick disconnect
(Q.D.) at the inlet to the regulator
at the pressure tank, do not dis-
connect the Q.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, depending upon the liquid
level in the tank. Tank pressure
should always be relieved by turn-
ing the regulator fully counter-
clockwise, or pulling the safety
valve ring.

REPLACEMENT OF PARTS
(Air Motor Assembly, See Page 5)
Do not pry front plate (40) or end plate (46)
from air motor body (43) 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
(42) after assembling front plate (40) on new
body (43) for alignment of parts. Always
install new end plate gaskets (41) 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 possibility of paint contamination of
the agitator air motor.
2. Turn off the main air supply to the tank.
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 clamps 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 lid 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 prema-
ture motor failure and will void
warranty.
Lubricate air motor daily by add-
ing 4 or 5 drops of SAE 10 weight
oil into air inlet fitting.
CIean the agitator shaft (54, Pg. 5) and the
propeller (56) at the end of each day. Occa-
sionally remove and clean the muffler strainer
felt (60) or replace, if necessary.
