ABRASIVE BLASTING MEDIA PRECAUTIONS
The blasting process emits abrasive media under pressure that breaks apart upon impact. The resulting dust is a combination of
the media and the material being removed by the abrasive. Both the media and the material being removed may have toxic
components such as lead in paint.
1. Check the abrasive media’s Material Safety Data Sheet (MSDS) for information on the health risks and preventative measure
that can be taken to minimize those risks.
2. Determine the toxicity of the material being removed and take appropriate measures.
3. Work in a well-ventilated area whenever possible or use containment methods such as cabinets or blastcleaning machines to
control the hazards from exposure.
4. Wear NIOSH approved respirators that protect both the lower face and eyes during blasting operations whenever possible.
WARNING! Sand or silica particle dust can result in the lung disease known as silicosis, when inhaled over a short period
of time. Silicosis causes shortness of breath, cough, fever and bluish skin (cyanosis). Seek immediate medical attention if these
symptoms appear.
AIR TOOL PRECAUTIONS
1. Extended exposure to air tool noise may cause hearing loss. Ear protection gear can reduce or eliminate the noise level.
2. Inspect the tool’s airline for cracks, fraying or other faults before each use. Discontinue use if the airline is damaged or hissing
is heard from the airline or connectors, while operating the tool. Replace the defective component/air line.
3. Do not allow people, mobile equipment or vehicles to pass over the unprotected air line. Position the airline away from high
traffic areas, in a reinforced conduit or place planks on both sides of the airline to create a protective trench.
4. Prevent damage to the air line by observing the following:
a. Never carry the tool by the air line.
b. Keep the air line behind the tool and out of the tool’s work path.
c. Keep the air line away from heat, oil, sharp edges or moving parts.
d. Do not wrap the air line around the tool as sharp edges may pierce or crack the airline. Coil the airline when storing.
5. A damaged or disconnected air line under pressure may whip around and inflict personal injury or damage the work area.
Secure the compressor’s air line to a fixed or permanent structure with clamps or cable ties.
6. 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.
VIBRATION PRECAUTIONS
This tool vibrates during use. Repeated or long-term exposure to vibration may cause temporary or permanent physical injury,
particularly to the hands, arms and shoulders.

close all Valves, detach the air supply, safely discharge any residual air pressure in the tool, and close all Valves again before
performing any procedure in this section.
To prevent serious injury:
Do not adjust or tamper with any control or component in a way not specifically explained within this manual. improper
adjustment can result in tool failure or other serious hazards.
Abrasive Selection
The type of abrasive selected effects the time required to blast clean a given surface area. Particularly for large surfaces, test
one or more of the following abrasives to determine which is most effective:
a. Silicon Carbide
b. Aluminum Oxide
c. Glass Beads
d. Walnut Shells
Warning! To prevent serious injury: Do not use sand or other blasting materials that contain crystalline silica.
Note: check to ensure the abrasives are dry and clean so that they do not clog the unit.
Note: The Nozzle size depends on grit of abrasive used.
The larger sizes are best suited to glass beads and walnut shells, while smaller sizes are best suited for fine aluminum oxide.
Change the nozzle as needed to suit the abrasive.

7. Turn on the compressor and set the regulator to the pressure recommended for this Blaster (60-125 PSI).
CAUTION! Do not exceed 125 psi.
OPERATING

WORKPIECE AND WORK AREA SET UP
1. Designate a work area that is clean and well-lit. The work area must not allow access by children or pets to prevent distraction
and injury.
2. If possible, place the Workpiece inside a sandblast cabinet. Otherwise, isolate the Workpiece to make sure no damage can
occur to nearby walls, tools, personal property, etc.
3. Route the Air Hose along a safe route to reach the work area without creating a tripping hazard or exposing the Air Hose to
possible damage. The Air Hose must be long enough to reach the work area with enough extra length to allow free movement
while working.
4. Secure loose Workpieces using a vise or clamps (not included) to prevent movement while working.
5. There must not be hazardous objects (such as utility lines or foreign objects) nearby that will present a hazard while working.
LOADING ABRASIVES INTO THE TANK
1. Check your abrasive to be sure that it is dry and won’t clog the steel abrasive shut-off valve (18B), abrasive outlet manifold (22),
abrasive hose (24), or other components.
2. Put on protective clothing and equipment.
3. Turn the brass air supply valve (18) to the OFF (horizontal) position.
4. Turn the brass shut-off valve (18B) to the ON (vertical) position.
5. Watch the pressure gauge (15) and make sure that it reads zero pressure.
6. Remove the filler cap (12) from the top of the tank (1).
7. Insert the funnel (29) and pour the abrasive media into the funnel. Fill the tank to no more than 3/4 full, or the amount required
to complete the task at hand if less sand is required.
NOTE: If the humidity is 90 to 100%, the water separator filter won’t be able to trap all of the moisture in a 3/4 full tank. It is better
to reduce the amount of abrasive and load the tank more frequently making sure to empty the water separator filter when needed.
This will reduce the possibility of clogging the bottom of the tank or the line.
OPERATING
1. Set the compressor’s regulator to 60 to 125 PSI. Do not set the compressor’s outlet regulator over 125 PSI.
NOTE: It is good practice to keep the air compressor in a different room than the room that you will be performing the abrasive
blasting process. The fine dust created during the blasting process can damage the air compressor. Use a longer air hose in
order to reach the abrasive blaster.
2. Connect the air supply to the inlet connector (19).
CAUTION! If any leaks are detected, disconnect the air hose and make any repairs before use.
3. Open the brass air supply valve (18) to pressurize the tank.
NOTE: The brass shut-off valve (18A) and the steel abrasive shut-off valve (18B) should be in the closed position in order to build
pressure in the tank.
WARNING! Watch the pressure gauge! Do not allow the pressure in the tank to exceed 125 PSI.
4. Open the brass shut-off valve (18A) to allow air to flow through the air hose (21).
5. Open the steel abrasive shut-off valve (18B) to allow the abrasive to be moved from tank (1). This will allow the abrasive to mix
with the air from the air hose (21) and flow into the abrasive hose (24).
6. Squeeze the On/Off control lever (42) on the deadman valve to begin the abrasive blasting process.
7. When you have finished the abrasive blasting process, release the On/Off control valve (42) and close the steel abrasive shut-
off valve (18B) to stop the flow of abrasives.
8. Close the brass air supply valve (18) to stop the tank from further pressurizing and turn off your air compressor.
9. Squeeze the On/Off control lever (42) on the deadman valve to relieve the pressure in the tank (1) and the air line. When the
pressure gauge (15) reads 0, the tank has been depressurized.
10. Close the brass shut-off valve (18A) and the brass air supply valve (18) when the tank has been depressurized and the
abrasive blasting process is complete.

OPERATING TIPS
1. The effectiveness of the blaster is increased by holding the nozzle as close to the area being cleaned as possible.
2. Move the blaster in steady, even strokes over the area to keep the abrasive blasting surface even.
3. When the abrasive blasting process is complete, clean the blasted surface with compressed air or a soft brush to remove any
residual abrasive.
4. Refinish promptly after the blasting process is complete. Newly abrasive blasted surfaces are more susceptible to corrosion.
TO EMPTY THE ABRASIVE TANK
1. Release the On/Off control valve on the deadman valve (42).
2. Close the steel abrasive shut-off valve (18B).
3. Close the brass air supply valve (18).
NOTE: Turn off the air compressor (if necessary).
4. Squeeze the On/Off control valve of the deadman valve to relieve pressure in the tank (1).
NOTE: The tank (1) is depressurized when the pressure gauge (15) reads 0.
5. Remove the tank filler cap (12) and empty the abrasive media into a suitable container to collect the abrasive.
CAUTION! Take care when emptying the tank of abrasives not to damage the pressure gauge or water separator filter.
NOTE: To prevent abrasive from being blown out of the container, cover part of the container with a board or cloth
to limit the amount of dust scattered.
CAUTION! Wear protective head gear such as goggles and a face protector as well as breathing protection to avoid
breathing in the dust created when emptying the abrasive tank.

NOTE: Disconnect the air source and discharge any residual air pressure in the air line before performing any maintenance.
1. The ceramic nozzle (37) 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 the ceramic
nozzle at regular intervals and replace as appropriate.
2. Always check for cracks and leaks in the deadman valve, hose, and tank. These problems must be fixed immediately due to the
dangers involved with air under pressure.
3. Check for damaged parts. Before using any tool, any part that appears to be damaged should be carefully checked to
determine that it would operate properly and perform its intended functions. Check for alignment and binding of moving parts,
for broken parts or mounting fixtures, or for any other condition that may affect proper operation.
NOTE: Internal components of the unit will wear out after repeated exposure to the blasting process. When the unit’s
performance declines, have the unit serviced by a qualified technician.
4. Use only identical replacement parts or accessories intended for use with this tool when servicing. Replace damaged parts
immediately.
5. 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.
6. The tank filler cap (12) is removable, make sure to clean and remove abrasives from the O-ring rubber seal (11).
CAUTION! Make sure that the tank has been depressurized before attempting to remove the tank filler cap (12).
7. After each use of the unit, perform the routine maintenance to your air compressor according to the compressor
manufacturer’s instruction manual.
8. If repairs are required, bring your tool to Princess Auto Ltd.
PLUGGED CONDITIONS
All blasting systems are prone to plugging or wear because of the abrasive material used. The blast nozzle may become plugged
from moist media. Try dislodging the media with a drill bit held in your hand. You will need to discard the moist media.
The abrasive media contents of the tank (1) may be stirred to loosen the media as well.
CAUTION! Make sure that the tank has been depressurized before attempting to remove the tank filler cap (12).
AIR SUPPLY REQUIREMENTS
Sandblasting requires a large volume of air at high pressure. The efficiency of your sand- blaster can be adversely affected by the
use of too small an air supply hose, insufficient air pressure or an overly large nozzle.

WEAR CONDITIONS
This is usually noted when an excessive amount of dust appears while blasting. Dust will occur if:
1. 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.
2. The deadman valve parts may wear out. This is usually evident when the blast pattern is too wide and ineffective; simply
replace the nozzle or orifice.
MAINTENANCE

LUBRICATION
