Operation  
Operation  
Checklist Before Starting  
• Make sure the water tank will remain fully supplied  
with clean water to avoid any possibility of the  
pump running dry during blasting.  
• 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 that the pot is clean and free of any  
internal debris.  
• 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).  
• Make sure air delivery valves are closed before the  
air supply compressor is started.  
• Make sure all required hose restraints and coupler  
pins are in working condition and properly installed.  
• 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 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.  
NOTICE  
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 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  
(see Technical Specifications, page 45).  
• Make sure the rubber gasket in each hose coupler  
is in working condition.

NOTE:  
Use a piece of test material similar to  
what you will be blasting.  
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:  
You may have to wait 1–2 minutes for the  
abrasive material to reach the nozzle.  
NOTE:  
Pot pressure and blast pressure should  
equalize during blasting. Only set pot pressure  
with the abrasive ball valve closed. Never adjust  
pot pressure while blasting.  
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  
DataTrak Controls, page 7 .  
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.

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.  
4. The equipment is now ready to wash any  
previously blasted surfaces.

9. Add 1–2 gallons (4–8 liters) of windshield wash  
to the water tank. Make sure that the rinse  
ball-valve and the drain ball-valve are left open.  
3. Drain the water tank by disconnecting the pump  
inlet hose and opening the inlet ball valve.  
NOTICE  
NOTE:  
All disposals must comply with national,  
state, and local regulations. In addition, if the  
water contains a rust inhibitor, you may want to  
retain and preserve the water due to the expense  
of the inhibitor.  
When ice forms behind the seals, the seals can  
become damaged. During storage, position all  
ball-valves in the open position.  
4. Drain the pump inlet hose, then insert the end  
into a windshield wash container. Choose a  
windshield wash with a rating that will protect the  
equipment for the lowest temperatures in your  
area.

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.

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).

diaphragm and to the end of the piston shaft.  
NOTE:  
Repair parts are available in Kit 17C131  
(EQ600) or Kit 17C129 (EQ300).  
1. Perform Pressure Relief Procedure, page 8 .  
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  
Using the Wash Feature, page 17) until  
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.  
1. Perform the Pressure Relief Procedure, page 8 .  
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.
