AIR MOTOR DRIVES
Important: Read and follow all instruc-
tions and SAFETY PRECAUTIONS before
using this equipment. Retain for future
reference.
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 at-
tempting 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 counterclock-
wise. 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
bearing assembly in lid until support
(60) is fully seated on bearing as-
sembly. 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.
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 2.8 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 2.8 gal. galvanized pres-
sure tanks. Includes removable agitator
and air motor with air shut off valve and
necessary hose and fittings for hookup
to tank regulator. Agitator supplied is not
suitable for use with halogenated hydro-
carbon based solvents.
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
propeller set screw (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). In-
stall and tighten air motor adapter
and shaft assembly into threaded
center hole in tank lid.
5. loosen set screws (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 set screws (25).
7. Install propeller (31) on end of agitator
shaft (30). Secure propeller with set
screw (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.
