Manual P/N: PB-MAC001

Abrasive blasting can create dust that may contain

toxic materials from abrasive material and the

surface being blasted. NEVER use abrasives

containing high amounts of crystalline silica

including silica sand/beach sand for abrasive

blasting. Airborne crystalline silica causes silicosis,

a fatal respiratory disease. Abrasive blasting can

create high levels of noise that may cause hearing

damage. Always use proper safety equipment

including respiratory protection, hearing protection,

and comply with local, regional and national safety

codes. Ensure all operators of the equipment are

properly trained and everyone in the area including

bystanders are protected from the hazards of

abrasive blasting. The manufacturer, wholesaler

and distributor assume no responsibility arising

from the failure to comply with this warning.

How CPR Systems Work

(Pressure Release)

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-Off 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 (Outlet Valve

on older models) 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 “Y” 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 (Outlet Valve on older models) opens allowing the compressed air in the pressure vessel to exit the

Abrasive Blaster through the Diaphragm Valve (Abrasive Trap & Outlet Valve on older models), and nally

through the Mufer. When all the pressure in the Pressure Vessel is released, blasting stops.

Operating Procedures

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.

Setting-Up The 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.

• 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-Off 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/turning the knob 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 Exhaust Mufer

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 Exhaust

Mufer without warning. Only Adjust the

Metering Valve after the Abrasive Blaster has

completely depressurized.

WARNING: Only personnel thoroughly trained in

abrasive blasting should operate the Abrasive

Blaster. This manual only provides basic

information on how to safely operate the features
