Operation
Operation
Checklist Before Starting
• Make sure to use the correct type of blast control.
Blasting with 150 feet (45 m) or more of blast hose
requires the use of an electric blast control. An
electric blast control can also be used on hose
lengths below 150 feet (45 m).
• Check the compressed air supply according to its
operator manual. Make sure the air being supplied
is clean and relatively free of moisture and oil
to prevent water contamination of the air control
components.
• Make sure the blast hose is laid out as straight as
possible between the equipment and the work site
(a coiled blast hose will uncoil under pressure).
• Make sure air delivery valves are closed before the
air supply compressor is started.
NOTICE
• Make sure all required hose restraints and coupler
pins are in working condition and properly installed.
Sharp bends in the blast hose could cause the
abrasive to wear through the hose and cause
premature failure of the hose.
• Make sure the equipment is situated on level
ground. Failure to keep the unit on level ground
will make it difficult or impossible to purge all of the
air from the pressure vessel.
• Make sure the rubber gasket in each hose coupler
is in working condition.
• Make sure the equipment is properly supported on
a surface that can hold its total weight. The weight
of all personnel, the material being blasted, and
any abrasive being stored must also be considered
Lifting the Trailer Systems
• Lift the unit with a lift apparatus rated for 10,000
lb (4535 kg) minimum.
• Make sure the water tank will remain fully supplied
with clean water to avoid any possibility of the
pump running dry during blasting.
• Do not lift the system by the lift ring on top of the
compressor.
• Make sure that the pot is clean and free of any
internal debris.
• Do not lift the system by the tie-down rings on the
trailer.

NOTE:
Use a piece of test material similar to
what you will be blasting.
NOTE:
The DataTrak can be used to assist in
setting the pump cycle rate. Optimal abrasive
media consumption typically occurs with the
cycle rate set at 7–10 cycles per minute.
NOTE:
Always start as gently as possible and
then increase the blast force as necessary to
clean without doing any damage to the substrate.
When properly set, the pump should cycle 7-10
times per minute. High production rate users
may need to increase cycle rate above 10 cycles
per minute.
NOTE:
Close the abrasive ball valve whenever
you stop blasting for more than 2-3 minutes.
This will help to extend the service life of the
diaphragm valve.

Blasting Tips
Blasting on Higher Surfaces
When blasting on a surface higher than the
equipment, make sure that there is a length of blast
hose on the ground equal to 10-20% of the height.
The hose on the ground prevents unspent abrasive
in the hose from back-filling the internal plumbing of
the panel.
When first learning the effects of the blaster, get a
better understanding of the results by starting at a
shallow angle (closer to 0° than to 90°) and keep
the nozzle approximately 16 in. (40 cm) from the
application. Observe the results, then reduce the
distance, steepen the angle, and adjust the blast
regulator.
For example: When blasting 50 feet (15 m) straight
up, use at least 10 feet (3 m) of blast hose on the
ground before the blast hose goes up to the blasting
height.
As the blast pressure is increased, slowly adjust
the metering valve and watch the DataTrak to
achieve 7-10 pump cycles per minute. See
NOTE:
The heavier and smaller the abrasive particle
(i.e. 80-grit), the more aggressive the results.

Operation
Metering Valve Settings
There is no fixed formula for what works best in each application. The information below works best for the
majority of the time. From this initial setting, adjustments can be made up or down to get the fastest removal
rates without damage to the surface.
Normal settings are: 110 psi (7.5 Bar, 0.75 MPa) initial pot setting, less than 1/2 turn open metering valve,
blasting pressure at 80 psi (5.5 Bar, 0.55 MPa). For applications requiring higher performance, use
high-performance abrasive (the heaviest mass @ 80 grit) such as Garnet, and the highest pressures the
compressor can support. The initial pot pressure should always be 30 psi (2.0 Bar, 0.2 MPa) above the
intended blast pressure.
Gradually make adjustments to meet the specific requirements for each application. Higher blast pressures
will require turning the abrasive metering valve slightly more open (and vice versa). Make the adjustments
(see DataTrak Controls, page 7 ) to achieve 7-10 cycles per minute to be the most efficient (cut at the fastest
rate while using the least amount of abrasive). Blasting pressures can range between 30 - 120 psi max
(2.0 Bar, 0.2 MPa – 8.2 Bar, 0.82 MPa).
Unlike conventional sandblasting, higher pressures do not necessarily mean better cleaning. Nozzle distance
and the angle to the surface has an effect on performance, as does the blast pressure. Choice of abrasive
also has a great effect. High-performance abrasive produces the best performance and can save enough
time to make up the difference in cost.
NOTE:
Blasting with 150+ feet of blast hose requires the use of an electric blast control.

Operation
Using the Wash Feature
2. Turn the selector valve to WASH.
The wash feature causes air-driven water (without
abrasive) to blast and rinse areas that have already
been blasted with abrasive. It is also a convenient
feature for flushing abrasive from the blast hose.
3. Blast 1 – 2 minutes until the abrasive is cleared
from the hose.
NOTICE
There will always be some residual abrasive in
the blast hose. Never use the wash feature on
any surface other than where you have blasted, or
intend to blast. It will affect/dull the surface.
NOTICE
Do not use the wash feature on wood that has
been blasted. It could damage the wood and cause
the grain to rise. Wait for the wood to dry and then
use a broom, brush, or vacuum to remove any
residual abrasive.

3. Make sure the bung is engaged with its seal.
Turn the selector valve to WASH, then open the
abrasive ball valve to pressurize the pot. Set the
pot pressure to 145 psi (9.9 Bar, 0.99 MPa).
Checking for Leaks
1. Open the dump valve. Check pot pressure
gauge, then close the dump valve.
4. Check the water pump to confirm that no water
is leaking from the TSL fill port.
NOTE:
The pump should stall after the pot
pressurizes. If the pump does not stall, replace
the seals. Refer to the pump manual for repair
information.
Look at the pressure gauge to confirm that all
pressure has been relieved from the pot.
5. Check for any water leaking from either check
valve. If a check valve is leaking, it must be
repaired or replaced. If the valves are damaged,
the pot will not be able to maintain pressure.
Also, check the pot pressure relief valve. If the
valve is weeping at pot pressures of 145 psi or
less, it needs to be replaced.
6. Close the abrasive ball valve , then disconnect
the quick coupler and confirm that the ball valve
is not leaking. Replace the abrasive ball valve
if it is leaking.

Troubleshooting
Pneumatic Blast Control Circuit
2. With the blast control activated, confirm that
there is air flowing from the disconnected tube.
1. At the Air-Relay, disconnect the push-to-connect
tubing and check the trigger circuit (from the blast
control handle).
NOTE:
The air flow should be at supply air
pressure but the air volume is reduced due to
the size of the fittings and tubing. If you do not
get supply air pressure, check the blast control
handle for proper operation, and check the blast
control hoses to make sure they are not kinked
or internally blocked.
3. Check the in-line filter at the industrial interchange
nipple connection on the side of the panel (where
you attach the blast control hose).
4. If the previous steps do not fix the issue, replace
the air relay (Kit EQ5179).

Repairing the Main Air Regulator
4. Unscrew the diaphragm cover for access to the
diaphragm and to the end of the piston shaft.
NOTE:
Repair parts are available in Kit 17C131
(EQ600) or Kit 17C129 (EQ300).
2. Make sure all of the air pressure is relieved in
the unit. Remove the water separator filter for
access to the piston cover and return spring.
3. Use a crescent wrench that can open to 2 in. (5
cm) to unscrew the piston cover.
NOTE:
There is a spring inside this cover.
5. Remove the diaphragm and inspect for any
cracks or tears. Replace the diaphragm if
necessary.
6. Carefully remove the spring and piston assembly,
then clean out any debris in the body of the
regulator.
7. Push the piston shaft and remove the piston from
the opposite end of the regulator housing.
8. Inspect the piston for any foreign matter that may
have been the cause for the piston to stay open.
9. Inspect for any damage to the piston shaft where
it interacts with the diaphragm cup.
NOTE:
Excessive wear here indicates the
main check valve is not sealing. Contact your
distributor if this happens.

Flushing the Diaphragm Valve
3. Disconnect the quick coupling at the abrasive
ball valve (not at the bottom of the pot).
This procedure can be performed with the component
still mounted in the panel.
If large-grit abrasive or other foreign matter become
lodged in the diaphragm valve, it will become
necessary to flush the valve. This is a simple
procedure; however, it does cause the release of a
large volume of air to escape through the released
quick coupling. You need to be prepared for the
release of air by pulling the quick coupler grommet
out of its groove so that it does not get lost.
4. Turn the selector valve to WASH. This will pump
water out of the quick coupler and allow you
to reach up inside and clear all abrasive and
remove the grommet.
1. Operate the unit in WASH (see
all abrasive clears from the blast hose.
5. Make sure nothing is in the path of the open
quick coupler, then engage the blast control
briefly and several times.
NOTE:
High flow air should escape through the
cam-lock coupling. If this does not occur, the
diaphragm valve is malfunctioning. Replace
entire diaphragm canister (EQ5140 – EQ600,
EQ5142 – EQ300).
6. Hold the male end of the quick coupler up to
the water coming from the cam-lock end of the
coupler. Clean off any dirt or abrasive.
2. Close the abrasive ball valve, then turn the
selector valve to RINSE.
7. Turn the selector valve to RINSE to stop the flow
of water.
8. Re-insert the grommet into its internal groove
inside the cam-lock.
9. Reconnect the quick coupler. If properly cleaned
and connected, there should be no leaks at the
coupler during operation.

Repairing the Diaphragm Valve
3. Replace the diaphragm (natural rubber
compound) and hand-tighten it as far as possible
to establish the alignment with the canister.
NOTE:
There are two shims between the
diaphragm and the actuator. Keep the shims
and reuse them (they do not come with
the replacement diaphragm). Do not cause
any pre-load or torque on the diaphragm by
over-tightening it in a misaligned position.
NOTE:
The diaphragm (17C127 – EQ300, 17C128
– EQ600) can be replaced without removing the
assembly from the panel. You will need an 8 mm
Allen wrench for the EQ600S and a 6 mm for the
EQ300S.
4. Insert all 4 Allen-head cap bolts but do not tighten
them.
5. Apply more than 80 psi (5.5 Bar, MPa) air
pressure to the regulator inlet to cause the piston
to retract.
6. With the piston retracted, hand-tighten the 4
Allen-head cap bolts.
7. Release the air pressure.
8. Tighten the cap-bolts in an alternating pattern
(see image below) to 80 +/- 8 in-lb (9 +/- 0.9 N•m).
This will cause a slight bulge in the diaphragm
between the canister and the stainless steel
casting.
2. Loosen all 4 Allen-head cap-bolts evenly and
then remove them completely while supporting
the canister of the diaphragm valve.

Cleaning the Auto-Vent Valve
3. Use the rinse hose to force water backwards into
the valve stem.
After the pop-up has been closed while filling the pot,
the auto-vent valve should release air (you should be
able to hear the air venting).
The pot pressure gauge will not show pressure until
the auto-vent valve has bled all of the air and sealed.
If the auto-vent valve does not release air, or if water
leaks from the stem during the fill process, the stem
valve may be clogged or faulty.
Perform the following procedure to clean a clogged
auto-vent valve.
1. Try to push and quickly release the valve with
your finger. If that does not cause the valve to
seal, open the dump valve to release all of the
pressure in the pot.
2. Turn the selector valve to RINSE.
NOTE:
If the previous steps fail to resolve
the issue, replace the whole valve assembly
(EQ1860).
NOTICE
The valve stem itself is internally attached to the
float and it is not field-serviceable. Do not try to
remove the valve stem. Damage to the equipment
will occur.
