Air Supply
Air supplies (compressors etc) shall be sited
in a non-hazardous area with a filter on the
air intake system to prevent the ingress of
dust or similar foreign material into the parts
where compression takes place.
Pressure Relief Procedure
Before attempting any installation of agitators
onto pressure feed tanks, the tanks must be
relieved of pressure as high pressure can
cause a serious injury. Pressure is
maintained in a pressure tank after the
system has been shut down. Before
attempting removal of fill plug or cover,
pressure must be relieved using the following
steps:
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
relief valve thumb screw counter-clockwise.
Wait until all the air has escaped through the
valve before removing the pressure tank
cover or fill plug installation.
4. Leave the air relief valve open until you
have reinstalled the cover or fill plug.
Air Motor Lubrication (all models)
An automatic air line filter/lubricator should
be installed in the air supply line no more
than 0.5m from the air motor. The filter
should be 5 micron. Install the lubricator level
with or above the motor so the oil mist will
blow directly into or down into the motor (see
Fig. 1).
Fill the oil reservoir with SAE 10W motor oil.
Adjust lubricator to feed 1 drop of oil for
every 1400 litres (50 cfm) of air or 1 drop per
minute for continuous running.

1. The PT-428/PT-419 direct drive Agitator
is designed for the 83C-211-CE and
83Z-211-CE tanks only. This Agitator
would be supplied with the tank and is
not supplied as a retro-fit or upgrade, but
only as a replacement.
2. Follow the pressure relief procedure at
the start of the INSTALLATION section.
3. If replacing the original unit, disconnect
the air supply hose from the air motor,
remove the propeller (56), then un-screw
the large nut (53). The unit will now
withdraw from the tank lid.
4. Re-fit the new unit in the reverse order.
Make sure the nut (53) is fully tightened
with a spanner (1—5/8” AF). Re-fit hoses
air hose.
OPERATION
Failure to operate and maintain these
agitators correctly could result in
premature motor failure and void
warranty.
Before operating any of these agitators
lubricate the air motor by adding 4 of 5
drops of SAE 10 weight oil into the air
fitting
QS-5012-CE Operation (Fig. 5)
1. Before operating the air motor, check the
oil level of the gearbox.
2. Remove the oil fill plug (88) and check
the oil level (see Fig. 3 below).
3. If oil level is low, add 140 weight SAE
motor oil. Replace the plug and tighten to
27Nm (20 ftlbs).
4. Before turning on the air supply, screw in
the air adjusting valve (65) fully. Turn on
the air supply and slowly open up the air
adjusting valve until the desired speed is
reached. A good starting point is 1 rev
per second (60 rpm).
5. Run the agitator continuously whist using
the tank.
6. When the tank is empty, the motor speed
will rise. Stop the motor to avoid un-
necessary high speed running.
QMS-430-CE and PT-428-CE Direct
drive models (Fig. 9)
1. Before turning on the air supply, screw in
the air adjusting valve (21) fully. Turn on
the air supply and slowly open up the air
adjusting valve until the desired speed is
reached. Use a minimum of 4 bar air
pressure. Do not exceed the maximum
of 7 bar.
2. Run the agitator continuously whist using
the tank.
3. When the tank is empty, the motor speed
will rise. Stop the motor to avoid un-
necessary high speed running.
PREVENTATIVE
MAINTENANCE
Pressure Relief Procedure
Before attempting any MAINTENANCE of
agitators onto pressure feed tanks, the tanks
must be relieve of pressure as high pressure
can cause a serious injury. Pressure is
maintained in a pressure tank after the
system has been shut down. Before
attempting removal of fill plug or cover,
pressure must be relieved using the
following steps:
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
relief valve thumb screw counter-
clockwise. Wait until all the air has
escaped through the valve before
removing the pressure tank cover or fill
plug installation.
4. Leave the air relief valve open until you
have reinstalled the cover or fill plug.
QS-5012-CE Preventative
Maintenance
1. Every 2 days, check the oil level as
described in the operation section. Top
up as necessary.
2. After the first 250 hours of operation,
remove the gearbox (see replacement of
parts section) and drain the gearbox oil.
Replace the oil as per the operation
section. Note—do this when the gearbox
is warm as the oil will drain easier.
3. After 6 months or 2500 operating hours,
replace the oil as in 2 above.
All Air Motors
1. Lubricate Air Motor as per Installation
section on page 3.
2. Check exhaust muffler filter every 500
hours. Clean or replace as necessary.
3. If the Air motor starts to run slowly or is
sluggish, flushing the motor with solvent
may restore its performance due to
excessive contamination from oil,
moisture and foreign particles. Use only
Gast #AH255B Flushing Solvent or
equivalent for this.
4. This cleaning operation should only be
carried out in a well ventilated area.
5. Wear eye protection.
6. Do not use combustible solvents for
flushing.
7. Disconnect the airline and muffler. Add
Fig 3
Fig 2

Page 6

about 100ml (4 fluid oz) of solvent into
the air intake port of the motor. Rotate
the motor by hand in both directions for a
few minutes.
8. Re-connect the airline and cover the
exhaust port with a cloth. Apply low
pressure 0.7bar (10psi) and re-start the
motor. Run until no more traces of
solvent can be seen.
9. The motor should be running smoothly. If
not, then a re-build may be required (see
QS-4016 Replacement of Parts).
REPLACEMENT OF
PARTS
QS-5012-CE Replacement of parts
(see Figs 5 & 6)
Before attempting any MAINTENANCE of
agitators on pressure feed tanks, the tanks
must be relieve of pressure as stated
previously.
1. Turn off and disconnect the mains air
supply hose with the air adjusting valve
(65).
2. Loosen the upper clamp screw (61) and
remove the air motor and gearbox
assembly.
3. Separate the motor and gearbox by
loosening locking screw (91).
4. Remove the spacer (94) and key (95)
from the motor shaft.
5. For the Air motor refer to QS-4016 Air
motor section.
Gear box
1. Remove the oil fill plug (88) or cover
plate (84) and drain gear box lubricant.
2. Disassemble the gearbox by removing
the cover (84), withdraw the gear shaft
(86) and washer (85).
3. Withdraw the worm gear (93) .
4. Inspect the seal (90) for signs of wear,
leaks or damage. Only remove if it needs
replacing.
5. Clean the seal housing and remove any
burrs or contaminants. These could
distort the new seal during fitting.
6. Inspect the gear shaft assembly (86) for
wear grooves, burrs or contamination of
seal sealing area on the shaft diameter.
If the seal sealing area is damaged the
shaft must be replaced.
7. Inspect all other parts for signs of wear,
chipping or other damage. Replace
damaged or worn parts.
8. If the oil seal (90) is being replaced,
check the new seal carefully for damage
before installing. Use an arbour press to
press the seal in. Use a close fitting tool
to the casting bore diameter to avoid
damaging the seal. Make sure the seal
lip is towards the bottom of the bore.
Press in squarely into the bore to avoid
warping. Check that the seal is fully
seated in the bottom of the bore.
9. Reassemble gear box in the reverse
order. Use new gaskets (87 and 92).
When re-fitting the air motor, slide
spacer (94) and fit key (95) before
engaging the motor to the gearbox.
Apply thread locking compound to the
locking screws (91) and tighten to 6.8
Nm (60 lbins). Refill the gearbox with oil
(SAE 10) as per previous section.
QMS-431-CE, 433-CE and 434-CE
