SPECIFIC SAFETY

WARNING! DO NOT let comfort or familiarity with the product (gained from repeated use) replace strict adherence to the tool safety rules. If you use this tool unsafely or incorrectly, you can suffer serious personal injury.
Review the safety and operation instructions for the air compressor before beginning abrasive blasting with this machine.

Use the correct tool for the job. This tool was designed for a specific function. Do not modify or alter this tool or use it for an unintended purpose.
Do not attempt to move the unit when the hopper contains abrasive.
Abrasive media is very slippery. Clear it from the workspace immediately to avoid personal injuries.

ABRASIVE BLASTING PRECAUTIONS

DANGER! Do not use sand or silicate particulate dust as an abrasive. Sand or silica particulate dust can result in the lethal lung disease known as silicosis when inhaled over a period of time as short as several weeks or as long as 5 to 10 years.
Silicosis causes shortness of breath, cough, fever and bluish skin (cyanosis). Seek immediate medical attention if these symptoms appear. Silicosis can kill you if untreated.
The abrasive blasting process emits abrasive media under pressure that breaks apart upon impact. The resulting dust is a combination of the abrasive media and the removed material.
Both the media and the material being removed may have toxic components, such as lead in paint.

Check the abrasive media’s Material Safety Data Sheet (MSDS) for information on the health risks and preventative measures you can implement to minimize those risks.
Use only abrasives specifically intended for blasting. Never use sand or silicates.
Inspect all seals for damage before each use.
Avoid exposure to hazardous dust created during the blasting process. Options include ventilation systems to remove or divert the dust, containment methods such as cabinets or blast-cleaning machines, or working outside. Always check municipal by-laws regarding abrasive blasting outdoors. Test the air quality to ensure that exposure is reduced by the chosen option.
Never point the abrasive blasting gun at people or animals. Never point the tool towards yourself. The abrasive media is under pressure and can cause a physical injury.
Ground the abrasive blasting cabinet to prevent static electricity build-up.

AIR TOOL PRECAUTIONS

Use only clean and dry compressed air as a power source. Contaminated or moist air will gradually damage the tool.
Discontinue tool use if it does not work properly or air is leaking. Tag or mark the tool as ‘defective’ or ‘out of service’ until repaired.
Check the manufacturer’s maximum pressure rating for air tools and accessories. Compressor outlet pressure must be regulated to never exceed the maximum pressure rating of the tool (see Specifications). Exceeding the maximum PSI rating can create a bursting hazard, causing injury and property damage.
Never use oxygen, combustible gas, or any other bottled gas as a power source. Any power source other than an air compressor could cause an explosion and serious personal injury.
Turn OFF the valve and discharge any remaining air pressure after each use or before adjusting the tool.
Do not leave the air tool unattended with its compressed air supply on. Turn off the compressed air supply and bleed the air tool of any remaining compressed air before leaving the air tool unattended.
Serious injury may occur from loose debris being propelled at high speeds from the compressed air stream. Always wear OSHA-approved safety glasses to protect the eyes during the operation of the air compressor.
Never point the air stream or tool at any point of your body, other people, or animals. Debris and dust ejected at high speed can cause an injury.
Always turn off the air compressor and drain tank pressure completely before attempting maintenance or attaching air tools. Release pressure slowly from the system.

AIR HOSE PRECAUTIONS

Inspect the tool’s air hose for cracks, fraying or other faults before each use. Discontinue use if the air hose is damaged or hissing is heard from the air hose or couplers. Replace the defective air hose.
Do not allow people, mobile equipment or vehicles to pass over the unprotected air hose. Position the air hose away from high traffic areas, in a reinforced conduit or place planks on both sides of the air hose to create a protective trench.
Prevent damage to the air hose by observing the following:
- a. Keep the air hose behind the tool and out of the tool’s work path.
- b. Keep the air hose away from heat, oil, sharp edges or moving parts.
- c. Do not wrap the air hose around the tool as sharp edges may pierce or crack the air hose. Gently coil the hose and either hang on a hook or fasten with a device to keep hose together when storing.
A damaged or disconnected air hose under pressure may whip around and inflict personal injury or damage the work area. Secure the compressor’s air hose to a fixed or permanent structure with clamps or cable ties.
Install an in-line shutoff valve or regulator to allow immediate control over the air supply in an emergency, even if a hose is ruptured.

POWER TOOL PRECAUTIONS

Do not use any power tool with a malfunctioning trigger, power switch, or control. A power tool that fails to respond to the controls is dangerous and can cause an injury.
- A qualified technician must repair and verify the power tool is operating correctly, before it can be used.
Shut the power off and disconnect the abrasive blasting cabinet from the power supply (if possible) before making any adjustments, cleaning, servicing, or when storing. Such preventive safety measures reduce the risk of starting the tool accidentally.
Avoid unintentional starts. Be sure that the regulator/throttle switch is in the neutral or OFF position when not in use and before connecting it to any air source.
Never point towards yourself. It could inflict an injury.

UNPACKING

WARNING! Do not operate the tool if any part is missing. Replace the missing part before operating. Failure to do so could result in a malfunction and personal injury.
Remove the parts and accessories from the packaging and inspect for damage.

OPERATIONS

WARNING! Before you begin using the abrasive blasting cabinet, make sure that the vent plug and the intake plug are in the OPEN position. Failure to follow these steps could result in severe personal injury, tool or property damage.

Clean the workpiece to remove all traces of oil, grease, or moisture. Allow the workpiece to dry before proceeding to use the abrasive blasting cabinet.
Pour the abrasive into the bottom of the cabinet to a depth of 6 to 7 inches.
Connect the tool to an air source.
Plug the power cord into a power outlet.
Turn on the lamps to illuminate the interior workspace.
Set the air pressure to around 80 psi for delicate or fragile workpieces. You can increase the air pressure slowly until you reach the desired finish on the workpiece.
Place the part you wish to abrasive blast in the cabinet. Always close and latch the lid after placing the part in the cabinet before blasting. Severe injury to the skin and eyes may result from exposure to the blast stream, as well as other health concerns.
Choose a nozzle size for the air gun. A larger nozzle will increase the volume of media available for cleaning but will require a higher airflow volume to compensate.
The blasting gun will pulsate if too much media is entering the airflow. The amount of media striking the workpiece will diminish if the meter valve is closed more than necessary.
After putting your hands into the gloves, firmly grasp the gun and depress the trigger. This should begin the abrasive flow. If no flow is seen, you may need to clear the intake tube. Simply move it around inside the cabinet to dislodge any blockage. If this does not work, see Care & Maintenance – Plugged Conditions,
Now you may begin finishing your part. You should move the blast stream continuously over the part in an even and circular motion. To avoid undesirable peening, the flow should not be too hard or concentrated.
- Change the gun angle until the media deflects towards the back of the chamber. This will reduce wear on the viewport window and the abrasive gun.
Release the trigger to stop the tool.
Remove the workpiece from the cabinet.
Stop the compressor once the task is complete and release residual pressure from the tool and air hose. Disconnect the air hose from the tool.
Switch off the lamps.
Unplug the abrasive cabinet cabinet from the wall outlet.

PRESSURE DROP

Apply the air consumption and pressure rate numbers to the tool’s air inlet, not the compressor’s outlet. Calculate the pressure drop for your air supply set-up and increase the compressor outlet pressure to compensate.
Make sure you do not exceed the maximum pressure for any part of your air supply system.
Installing a pressure gauge at the tool inlet is the best way to measure the air pressure and adjust the compressor’s output.

ABRASIVE BLASTING MEDIA

IMPORTANT! Read the abrasive blasting media precautions section before use and consult the Material Safety Data Sheet for each abrasive media product.
There are many different abrasive media the tool can use as an abrasive. Each type of abrasive has a different application and effect on the object being blasted.
Each abrasive may also have hazards or health issues associated with their use.
Store abrasive in a dry location. Wet abrasive will clog the unit.

Recommended Abrasive Blasting Media for this model:

Aluminum oxide grit
Glass bead
Crushed glass
Steel shot
Copper slag
Garnet
Crushed nutshells

CARE & MAINTENANCE

Maintain the tool with care. A tool in good condition is efficient, easier to control and will have fewer problems.
Inspect the tool components periodically. Repair or replace damaged or worn components. Only use identical replacement parts when servicing.
Maintain the tool’s labels and nameplates. These carry important information. If unreadable or missing, contact Princess Auto Ltd. for replacements.

WARNING! Only qualified service personnel should repair the tool. An improperly repaired tool may present a hazard to the user and/or others.

ABRASIVE BLASTING MAINTENANCE

Disconnect air source before performing any maintenance.

The nozzle will wear away over time, causing the internal diameter to widen and disperse the media over a larger area, reducing the tool’s efficiency. The compressor will also need to work harder to maintain the pressure. Check at regular intervals and replace as appropriate.
Dust will occur if the abrasive blasting media is worn out. If it has lost its granular or spherical appearance or has a lot of debris mixed in from the parts being blasted, replace the abrasive blasting media. This is usually noticed when the abrasive media that exits the nozzle resembles more of a cloud than a stream.
Always check for cracks and leaks in the gun, hose, and cabinet. These problems must be fixed immediately due to the dangers involved with air under pressure.
Use only identical replacement parts or accessories intended for use with this tool when servicing. Replace damaged parts immediately.
Keep the tool clean. Wipe the tool with a clean cloth and periodically blow out all areas with compressed air. If compressed air is not available, use a brush to remove dust from areas. Do not use harsh chemicals or solvents to clean the tool. These chemicals could seriously damage the housing.

PLUGGED CONDITIONS

All blasting systems are prone to plugging or wear because of the abrasive material used. The following items should be checked as indicated.

The blast nozzle may become plugged from moist media. Try dislodging the media with a drill bit held in your hand. You need to discard the moist media.
If the abrasive pick-up hose appears plugged, simply move it around inside the cabinet to dislodge any blockage. If this does not work, try dislodging the media with a drill bit held in your hand. You need to discard the moist media. Dust may fly up when you do this so make sure the lid is down!
Hold a thumb over the air gun nozzle to prevent air from escaping. Press down on the foot pedal. The air flow will divert up the siphon tube and should dislodge any clogged media.

WEAR CONDITIONS

This is usually noted when an excessive amount of dust appears in the cabinet.

Dust will occur if:

The abrasive blasting media is worn out if it has lost its granular or spherical appearance or has a lot of debris mixed in from the parts being blasted, replace it.
- This is usually noticed when the abrasive media that exits the nozzle resembles more of a cloud than a stream.
The air outlet vent is plugged or air flow out is blocked. Cleaning this vent should help reduce dust in the cabinet. The gun parts may wear out. This is usually evident when the blast pattern is too wide and ineffective; simply replace the nozzle or orifice.
- a. You can extend the nozzle’s lifespan by checking it for uneven wear every 10 to 12 hours. Twist the nozzle a quarter turn to compensate for this wear.
Check the nozzle’s inner diameter from time-to-time or when the media spray seems too diffuse. Replace when the nozzle’s inner diameter increases by 1/16 in. or more.

ACRYLIC WINDOW MAINTENANCE

The viewing and lamp windows have an interior replaceable plastic film to protect them from the abrasive media.
Remove the heavily pitted plastic protectors and replace them with the new films.

Remove the (#20) from the viewing window bracket (#20). Set the screws and bracket aside.
Remove the rigid plastic sheet (#22) and glass (#23). Set both aside.
Remove and discard the protective film (#24).
Place a new protective film in place. Place the glass and rigid plastic sheet on top of the film.
Place the bracket over the window and secure it with the screws.

CLEANING

Wipe the tool with a clean cloth and periodically blow out all areas with compressed air. If compressed air is not available, use a brush to remove dust from areas.
Do not use harsh chemicals or solvents to clean the tool. These chemicals could seriously damage the housing.

DISPOSAL

Recycle a tool damaged beyond repair at the appropriate facility.
