C-Series Jr - 0.5 / 1.0 Cu Ft User’s Manual
WARNING: This section of the manual is designed to give you a general understanding of how the
Abrasive Blaster functions. All sections of this manual must be read and understood before
operating the equipment.
Flow of Compressed Air
Flow of Abrasive
Flow of Exhaust Air
During Blow-down
ADDING ABRASIVE
Abrasive is added through the hole in the top of the Abrasive Blaster where the Pop-up and its seat are
located. When abrasive is added, it ows down through the hole, around the Pop-up, and down to the
bottom of the pressure vessel where it will exit through the Metering Valve when blasting is started.
PRESSURIZATION
When a compressed air source (such as an air-compressor) is connected to the inlet of the Abrasive
Blaster and the Inlet Shut-O󰀨 Valve is opened, compressed air ows to the Inlet Valve where it is stopped.
When the control handle is activated, the Inlet Valve opens and air ows into the Pressure Vessel causing
the Pop-up (located internally) to seal against its seat. Simultaneously, the Diaphragm Valve closes
sealing the Pressure Vessel allowing it to hold pressure. Air will also continue past the Choke Valve,
through the Pusher Line, and nally to the “tee” under the Metering Valve where it is mixed with abrasive.
The mixture of compressed air and abrasive will now exit the Abrasive Blaster through a blast hose and
nozzle connected to the coupling under the Metering Valve and blasting begins. It is important to note
that, some abrasive will collect at the base of the Metering Valve causing the blast hose to pulsate and
spray abrasive erratically for a short time while pressure builds up in the pressure vessel. This is normal
and will not damage the Abrasive Blaster.
DEPRESSURIZATION (BLOW-DOWN)
When the control handle is released in a pressure release (CPR) system, the Inlet Valve automatically
closes stopping the ow of compressed air into the Pressure Vessel. Simultaneously, the Diaphragm
Valve opens allowing the compressed air in the pressure vessel to exit the Abrasive Blaster through the
Diaphragm Valve. When all the pressure in the Pressure Vessel is released, blasting stops.

WARNING: The Procedures provided in the Operating Procedures section of the manual are designed to
provide basic information on how to safely operate the features of Pirate Brand® CPR Series Abrasive
Blasters. Only personnel thoroughly trained in abrasive blasting should operate the Abrasive Blaster.
INSPECT PRESSURE VESSEL
When you receive your Abrasive Blaster, remove the
Handway Assembly and check for foreign items that may
have fallen into the Abrasive Blaster through the Pop-up
opening. Remove any foreign materials and reinstall the
Handway Assembly.
DANGER: Never perform any maintenance or
attempt to open the Abrasive Blaster in any way
while it is pressurized. The violent release of
compressed air and propelled objects will cause
serious injury or death.
RE-TIGHTEN HANDWAY ASSEMBLY
After the Abrasive Blaster has been pressurized for the rst
time, tighten the nut on the Handway Assembly. Tightening
the nut on the Handway Assembly should also be done any
time after the handway has been removed for maintenance
before and after the next pressurization.
DANGER: Never perform any maintenance or
attempt to open the Abrasive Blaster in any way
while it is pressurized. The violent release of
compressed air and propelled objects will cause
serious injury or death.
PURGE AIR SUPPLY HOSE
Before connecting the Air Supply Hose to the Abrasive
Blaster, purge the hose of any moisture or foreign debris.
Standing water or moisture in the air line will cause
degraded performance of the Abrasive Blaster. Air supplied
to the Abrasive Blaster must be clean, dry and cool.
ATTACH REMOTE CONTROL HANDLE
Attach the Remote Control Handle to the Blast Hose near
the Nozzle with hose clamps or heavy wire ties. Form a loop
of Twinline/Control Cord that comes 6” away from the Blast
Hose, runs 6” parallel to the Blast Hose, and comes 6” back
to the Blast Hose. Using duct tape, attach the Twinline/
Control Cord to the Blast Hose where the loop ends by
wrapping the tape around the Twinline/Control Cord twice
and then around the Blast Hose. This creates a strain-relief
attachment and is only necessary on the rst connection
near the Control Handle. Starting from the Nozzle end of
the Blast Hose, attach the Twinline/Control Cord to the blast
hose by wrapping duct tape around both every 3 feet.

following conditions occur:
• All “BEFORE YOU BLAST” procedures have
been followed.
• The Inlet Shut-O󰀨 Valve is closed.
• The Inlet Valve Petcock is closed.
• The Remote Control Handle is released.
• All hose connections are secure and have a safety clip
installed.
• The Abrasive Blaster is set up in a safe and level location
where all people in the vicinity are aware of its presence.
• All necessary safety equipment is present and being
worn by all people in the vicinity of the Abrasive Blaster.
• Only personnel who have been thoroughly trained and
have read and understand the manual are in the vicinity
of the Abrasive Blaster
When these conditions are met, turn on the compressed air
source and open the Inlet Shut-O󰀨 Valve on the Abrasive
Blaster. The Abrasive Blaster is now ready to begin blasting.
DANGER: Never perform any maintenance or
attempt to open the Abrasive Blaster in any way
while it is pressurized. The violent release of
compressed air and propelled objects will cause
serious injury or death.
DANGER: Never supply compressed air
exceeding 150 PSI (10.3 BAR) to the Abrasive
Blaster.
WARNING: The Blast Hose may kick back when
Remote Control Handle is activated. Be
prepared and brace yourself for kick back.
Blast Hoses will normally kick back erratically for
a short time when the Abrasive Blaster is started.
WARNING: All those who will be in the area
while blasting is to occur must be properly
trained, read the manual, and wearing safety
equipment to protect from the hazards described
by the WARNING and DANGER labels located
on the Abrasive Blaster. If any labels are worn
or missing they must be replaced.
WARNING: 100 PSI Minimum. Failure to provide
a constant air supply of at least 100 PSI can
cause excessive wear to multiple components
and the control system to operate improperly.
USING THE ABRASIVE BLASTER
After pressurizing the Abrasive Blaster, it is ready to begin
blasting. Fold down safety ap lever lock and squeeze the
Remote Control Handle to start the ow of abrasive and
compressed air. Adjustments to the air/abrasive mixture
can be made by swinging the handle on the Metering
Valve. There will be a delay between a change made at
the Metering Valve and what comes out of the Nozzle
depending on the length of Blast Hose being used.
To stop the ow of compressed air and abrasive,
release the Remote Control Handle and blasting will stop
after a short time. How long it takes for blasting to stop
will depend on the length of Blast Hose being used. The
pressure vessel will automatically exhaust through the
Diaphragm Valve causing a rush of compressed air that
can propel any loose objects, debris or spilled abrasive at
nearby personnel. For this reason, personnel must not be
located near the Abrasive Blaster when blasting is taking
place.
DANGER: Airborne particles produced by
abrasive blasting can cause respiratory disease.
All persons operating or located near the blasting
site must wear approved NIOSH / OSHA
approved breathing equipment. Never use
abrasive containing silica.
DANGER: Never stand near an Abrasive Blaster
when it is in operation. The release of the
Remote Control handle will cause a sudden
release of compressed air from the Diaphragm
Valve without warning. Only Adjust the
Metering Valve after the Abrasive Blaster has
completely depressurized.

C-Series Jr - 0.5 / 1.0 Cu Ft User’s Manual
DRAINING THE MOISTURE SEPARATOR
(if equipped)
During blasting, the Moisture Separator must be periodically
drained. The best way to accomplish this is to leave the
drain valve slightly open all the time so it constantly leaks
air and forces moisture out.
WARNING: The Abrasive Blaster must be
supplied with clean, cool, dry compressed
air in order to function properly.
SHUTTING DOWN THE ABRASIVE BLASTER
When blasting is complete, the Abrasive Blaster will need
to be shut down. Make sure the Remote Control Handle is
released then close the Inlet Shut-O󰀨 Valve and open the
Inlet Valve Petcock.
DISCONNECTING AIR SUPPLY HOSE
After the Abrasive Blaster has been depressurized and the
Inlet Valve has been closed, the Compressed Air Supply
Hose may still contain pressure which must be released
before disconnecting the hose. To do this shut o󰀨 the
compressed air at its source, and open the Inlet Shut-O󰀨
Valve on the Abrasive Blaster.
Next, open the petcock at the top of the Inlet Valve. For
systems with electric remote controls, you must be
connected to a power source and hold down the Remote
Control Handle to allow air to bleed out through the Inlet
Valve Petcock.
When you no longer hear air escaping through the Inlet
Valve petcock, squeeze the Compressed Air Supply Hose
to conrm it is soft and does not contain compressed air.
After conrming the absence of compressed air in the
Compressed Air Supply Hose it is ready to be disconnected.
DANGER: Never disconnect any compressed air
supply hose without rst performing the
“DISCONNECTING AIR SUPPLY HOSE”
procedure described above. Failure to do so
can cause the hose to blow o󰀨 violently injuring
or killing nearby people.

push minor obstructions such as a small amount of wet abrasive,
a piece of paper from a bag, or bridged paint chips through the
Metering Valve and out the Nozzle. Readjust the Metering Valve
back to the desired setting for blasting, and check to see if the
obstruction has been cleared.
If there is still an obstruction, depressurize the Abrasive Blaster.
Completely remove the Metering Valve. The remaining abrasive
in the pressure vessel should pour out in a steady stream. If you
do not see a steady stream of abrasive, then there is a large
obstruction such as a large piece of paper from a bag of abrasive.
If you have determined there is a large obstruction, then the
obstruction must be removed from inside the Pressure Vessel. To do
this, make sure the Abrasive Blaster is depressurized and remove
the Handway Assembly. Scoop or vacuum out all the abrasive from
inside the pressure vessel and remove the obstruction. Reinstall
the Handway Assembly and Metering Valve and tighten them
securely, then Rell the Abrasive Blaster.
It is recommended that a screen be used to prevent foreign
objects from entering the Abrasive Blaster and causing an
obstruction.
4. The Abrasive Blaster has wet abrasive in it. The wet abrasive
must be removed by depressurizing the Abrasive Blaster, removing
the Handway Assembly, and scooping or vacuuming it out.
Dry abrasive must always be used. Clean, cool, dry air must
be supplied to the Abrasive Blaster in order to prevent the
abrasive from getting wet. For Abrasive Blasters being used
outside, it is recommended that a lid be used to keep water
from entering the Abrasive Blaster.
ABRASIVE STREAM IS TOO HEAVY OR
THROBBING WHEN BLASTING
Possible Causes:
Note: CPR Systems may throb temporarily when starting up if
abrasive has collected in blast hose from previous use. This is
normal and requires no action to correct.
1. Choke Valve is partially closed. Never run the Abrasive Blaster
with the Choke Valve in any other position except fully open or
damage to the Abrasive Blaster will occur.
2. The Metering Valve needs to be adjusted.
LOW PRESSURE AT THE NOZZLE
Possible Causes:
1. Air compressor is the wrong size (too small) or the load
button has not been pushed or turned on. (100 PSI Minimum)
2. Nozzle is worn out and the compressor cannot keep up with
the increased demand.
3. Air supply hose to the blast machine is too small.
4. There is a hole in the blast hose.
5. Control hoses and/or ttings are leaking.
6. Pop-up is not sealing properly.
7. Handway Assembly is leaking.
8. Choke Valve is partially closed. Never run the Abrasive Blaster
with the Choke Valve in any other position except fully open or
damage to the Abrasive Blaster will occur.
9. Abrasive Metering Valve is open too far.
10. Obstruction in Nozzle.
11. Regulator needs adjustment (if equipped).
12. Inlet Valve/Diaphragm Valve is not opening/closing fully
due to inadequate control pressure.
13. Inlet Valve is damaged, defective, worn out, or not
lubricated properly causing it to not open fully.
14. Diaphragm Valve is damaged, defective, or worn out.
ABRASIVE BLASTER WILL NOT TURN ON OR
IS SLOW TO TURN ON
Possible Causes:
1. Air compressor is the wrong size (too small) or the load
button has not been pushed or turned on. (100 PSI Minimum)
2. Inlet Valve Petcock is open.
3. Nozzle is worn out and the compressor cannot keep up with
the increased demand.
4. Air supply hose to the blast machine is too small.

8. Obstruction in Nozzle.
9. The Pneumatic Control Handle is damaged, defective or
worn out (if equipped).
10. The Electric Control Handle is damaged, defective or worn
out (if equipped).
11. Power Source (battery or AC-DC converter) is not providing
su󰀩cient power to open electric control valves (if equipped).
12. The Electric Control Cord is damaged, defective or worn
out (if equipped).
13. The Electric Control Valve is damaged, defective or worn
