manufacturer provides written approval. Only
use the Agitator with the proper lid assembly
41-3205.
KEEP EQUIPMENT GUARDS IN PLACE
Do not operate the equipment if any safety
devices or guards have been removed.
KNOW WHERE AND HOW TO SHUT OFF
THE EQUIPMENT IN CASE OF AN
EMERGENCY
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.
FIRE AND EXPLOSION HAZARD
Improper equipment grounding, poor ventilation,
open flames or sparks can cause hazardous
conditions and result in fire or explosion and
serious injury.
ELECTRIC SHOCK/GROUNDING
Improper grounding or sparks can cause a
hazardous condition and result in fire, explosion
or electric shock and other serious injury.
Check electrical continuity of the air supply to
earth - should be no greater than 106 Ω.
Electrically bond all metallic equipment to earth.
Should be no greater than 1 Ω.
STATIC CHARGE
Fluid and air may develop a static charge that
must be dissipated through proper grounding of
the equipment, objects to be sprayed and all
other electrically conductive objects in the
dispensing area.
Use suitably approved static dissipating or
conductive air supply hoses.
EQUIPMENT MISUSE HAZARD
Do not exceed the stated maximum working
pressures and motor speed as specified on
page 3.
FIRE AND EXPLOSION HAZARD
Use lubricating medium resistant to
carburisation and has an auto ignition
temperature of 185ºC for T4 and 150ºC for T5
equipment.
SPECIAL CONDITIONS FOR SAFE USE REQUIRED BY ATEX CERTIFICATION
PRESSURE RELIEF PROCEDURE
Always follow the pressure relief procedure in
this instruction manual.

INSTALLATION
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.
Air Motor Lubrication
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.
Kit Assembly
Only Use the proper Lid assembly 41-
3205 with this Agitator.
1. Remove the propeller (12) from the shaft
(3) by loosening the lock screw 11.
2. Unscrew the locknut (7) from the
housing, and remove washer (10).
3. Push out the blank (16) in the lid (17),
insert the shaft into the aperture in the lid
and rotate until the pin locates in the slot.
4. Slide the washer (10) over the shaft, the
raised centre towards the locknut.
5. Replace the locknut (7) and tighten.
6. Replace the propeller (12) and secure
with screw (11).
7. Remove the blank (14) for the pickup
tube or pipe.
8. Place the lid assembly over the pail or
drum.
9. Make sure the pail has a minimum depth
of 325mm for a 25mm clearance, or the
propeller may contact the bottom and
create possible sparking hazards.
10. Clamp the lid by screwing in the 3 thumb
screws (15) evenly to centre the lid to the
pail.
11. 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.
12. Close the Air Adjusting valve (2) by
rotating clockwise.
13. Connect the airline to the valve (2). The
Agitator is now ready for use.
OPERATION
Failure to operate and maintain these
agitators correctly could result in
premature motor failure and void
warranty.
If not already done so, 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.
1. Before turning on the air supply, screw in
the air adjusting valve (2) fully. Turn on
the air supply and slowly open up the air
adjusting valve.
2. The optimum speed is dependent on the
type of coating material being agitated. If
the speed it too high, the propeller will
cavitate and aerate the material.
3. It is not recommended to run the motor
faster than 1000 rpm. Do not exceed
3000 rpm.
4. When the tank is empty, the motor speed
will rise. Stop the motor to avoid un-
necessary high speed running.
Prolonged high speed running may result
in premature wear and failure of the
motor.
PREVENTATIVE
MAINTENANCE
1. Turn off the main air supply to the
Agitator with the isolator valve.
2. Check exhaust muffler for blockage.
Clean if 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 ion a well ventilated area.
5. Wear eye protection.
6. Do not use combustible solvents for
flushing.
7. Disconnect the airline and muffler. Add
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
Replacement of Parts).
REPLACEMENT OF
PARTS
1. Remove the propeller (12) from the shaft
(3) by loosening the lock screw (11).
2. Unscrew the locknut (7) from the
housing, and remove washer (10).
3. Withdraw the Agitator from the aperture
in the lid.
4. Loosen the top 2 screws (11) in the
