Important: Read and follow all instruc-
tions and SAFETY PRECAUTIONS before
using this equipment. Retain for future
reference.
DESCRIPTION
the air motors covered in this service bul-
letin are designed to drive paint agitators
when connected to a source of clean, dry,
air pressure.
Qs-5012 air motor drive, 15-1 gear reduced
for pressure tank agitator. Includes air
adjusting valve with necessary hose and
fittings for hookup to tank regulator.
QMs-430 direct drive air motor and agita-
tor assembly for 2 gal. stainless pressure
tanks. Includes removable agitator and air
motor with air shut off valve and neces-
sary hose and fittings for hookup to tank
regulator. agitator supplied is suitable
for use with halogenated hydrocarbon
based solvents.
QMG-416 direct drive air motor and agita-
tor assembly for 2 gal. galvanized pressure
tanks. Includes removable agitator and air
motor with air shut off valve and neces-
sary hose and fittings for hookup to tank
regulator. agitator supplied is not suitable
for use with halogenated hydrocarbon
based solvents.
Qs-5003 air motor drive, 15-1 gear re-
duced for paint drums having built-in
agitators. Includes air adjusting valve for
1/4" npt(M) inlet.
High pressure can cause serious
injury. Pressure is maintained in
a pressure tank after the system
has been shutdown. Before
attempting removal of fill plug
or cover, relieve tank pressure.
Pressure Relief Procedure
1. turn off the main air supply to the
tank.
2. close air inlet valve located on tank
air manifold.
3. Bleed off air in the tank by turning
the air inlet valve handle counter-
clockwise. Wait until all the air has
escaped through the valve before
removing the pressure tank cover or
fill plug.
4. leave the air relief valve open until
you have reinstalled the cover or fill
plug.
INSTALLATION
QS-5012 Installation onto Pressure Tank
with Agitator (Refer to Figure 3.)
1.
position agitator assembly over bear-
ing assembly in lid until support (60)
is fully seated on bearing assembly. It
may be necessary to rotate the drive
assembly in order to get the agitator
assembly to engage in the gear box.
Once engaged, again rotate the drive
assembly until the air motor inlet and
exhaust ports are aimed toward the
rear of the tank. this will allow proper
hookup of air hose and fittings to the
tank regulator.
2. tighen hex head cap screw (61).
3. Remove main air supply inlet valve
from tank regulator and install service
tee (67) in open port.
4. connect tank air supply inlet valve
to open end port of service tee (67).
Install nipple (64) in open port of
service tee.
5.
If not already connected, install elbow
(63) in air motor inlet port and upper
nipple (64) in open elbow port. connect
air adjusting valve (65) to upper nipple.
connect hose assembly (66) between
lower nipple (64) and air adjusting
valve.
QMS-430 and QMG-416 Installation Into
Pressure Tank (Refer to Figure 1.
1.
Follow pressure relief procedure before
removing or loosening any tank lid
components.
2.
If not already separated, loosen propel-
ler setscrew (32) and remove propeller
from shaft.
3. Remove seal plug from paint tank
lid and clean sealing surface around
threaded port.
4. Make sure that the O-ring (26) is fully
seated in groove of adapter (24). Install
and tighten air motor adapter and shaft
assembly into threaded center hole in
tank lid.
5. loosen setscrews (25) in adapter. Ro-
tate air motor assembly until inlet port
is aimed toward the rear of the tank to
allow hookup of air hose and fittings
to supply air inlet of tank regulator
or service tee. air hose provided for
hookup is 10" long.
6. Retighten both setscrews (25).
7. Install propeller (31) on end of agita-
tor shaft (30). secure propeller with
setscrew (32).
8. Remove main air supply inlet valve
from tank regulator and install service
tee (23). Install lower nipple (20) in
open port of service tee.
9. connect tank air supply inlet valve to
end port of service tee (23). Install lower
nipple (20) in open port of service tee.
10. If not already connected, install elbow
(19) in air motor inlet port. Install upper
nipple (20) in open port of elbow. con-
nect air adjusting valve (21) to upper
nipple. then, connect hose assembly
(22) between air adjusting valve and
lower nipple.
