Silicosis Safety Measures
DO NOT USE SAND!
Abrasive blasting with sand (which contains crystalline silica) can cause
silicosis (a serious lung disease), cancer and death. To reduce crystalline silica
exposures in the workplace and prevent silicosis and silicosis-related deaths:
1. Prohibit silica sand (or other substances
containing more than 1% crystalline silica)
as an abrasive blasting material and
substitute less hazardous materials.
2. Conduct air monitoring to measure
worker exposures.
3. Use containment methods such as blast-cleaning
machines and cabinets to control the hazard
and protect adjacent workers from exposure.
4. Practice good personal hygiene to avoid
unnecessary exposure to silica dust.
5. Wear washable or disposable protective
clothes at the work site. Shower and change
into clean clothes before leaving the work site
to prevent contamination of cars, homes and
other work areas. Avoid skin exposure.
6. Always wear a NIOSH approved respirator and
safety goggles. Ventilate the work area properly.
7. Provide periodic medical examinations for all
workers who may be exposed to crystalline silica.
8. Post signs to warn workers about the hazard and to
inform them about required protective equipment.
9. Provide workers with training that includes
information about health effects, work practices
and protective equipment for crystalline silica.
10. Report all cases of silicosis to State health
departments and to OSHA or the Mine Safety
and Health Administration (MSHA).
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. To
reduce the risk of vibration-related injury:
1. Anyone using vibrating tools regularly or for
an extended period should first be examined
by a doctor and then have regular medical
check-ups to ensure medical problems are not
being caused or worsened from use. Pregnant
women or people who have impaired blood
circulation to the hand, past hand injuries,
nervous system disorders, diabetes, or Raynaud's
Disease should not use this tool. If you feel
any symptoms related to vibration (such as
tingling, numbness, and white or blue fingers),
seek medical advice as soon as possible.
2. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration-related injury.
3. Wear suitable gloves to reduce the
vibration effects on the user.
4. Use tools with the lowest vibration
when there is a choice.
5. Include vibration-free periods each day of work.
6. Grip tool as lightly as possible (while still keeping
safe control of it). Let the tool do the work.

Air Supply
TO PREVENT SERIOUS INJURY FROM EXPLOSION:
Use only clean, dry, regulated, compressed air to power this tool.
Do not use oxygen, carbon dioxide, combustible gases,
or any other bottled gas as a power source for this tool.
1. Incorporate a filter, regulator with pressure
gauge, dryer, in-line shutoff valve, and quick
coupler for best service, as shown page 10
and page 11. An in-line shutoff ball valve
is an important safety device because it
controls the air supply even if the air hose
is ruptured. The shutoff valve should be a
ball valve because it can be closed quickly.
Note: An oiler system should not be used
with this tool. The oil will mix with the material
being propelled, causing poor results.
2. Attach an air hose to the compressor's air outlet.
Connect the air hose to the air inlet of the tool.
Other components, such as a coupler plug
and quick coupler, will make operation
more efficient, but are not required.
WARNING! TO PREVENT SERIOUS INJURY
FROM ACCIDENTAL OPERATION:
Do not install a female quick coupler on the tool.
Such a coupler contains an air valve that will
allow the air tool to retain pressure and operate
accidentally after the air supply is disconnected.
Note: Air flow, and therefore tool performance, can
be hindered by undersized air supply components.
The air hose must be long enough to reach
the work area with enough extra length to
allow free movement while working.
3. Turn the tool's throttle or switch to the off position;
refer to Operation section for description of controls.
4. Close the in-line shutoff valve between
the compressor and the tool.
5. Turn on the air compressor according to
the manufacturer's directions and allow it
to build up pressure until it cycles off.
6. Adjust the air compressor's output regulator
so that the air output is enough to properly
power the tool, but the output will not exceed
the tool's maximum air pressure at any time.
Adjust the pressure gradually, while checking the
air output gauge to set the right pressure range.
7. Inspect the air connections for leaks.
Repair any leaks found.
8. If the tool will not be used at this time, turn off
and detach the air supply, safely discharge
any residual air pressure, and release
the throttle and/or turn the switch to its off
position to prevent accidental operation.
Note: Residual air pressure should not be present
after the tool is disconnected from the air supply.
However, it is a good safety measure to attempt to
discharge the tool in a safe fashion after disconnecting
to ensure that the tool is disconnected and not powered.

User-Maintenance Instructions
Procedures not specifically explained in this manual must
be performed only by a qualified technician.
TO PREVENT SERIOUS INJURY FROM ACCIDENTAL OPERATION:
Close all Valves, detach the air supply, safely discharge any residual air pressure in the tool
(see ″After Blasting:″ on page 13), and close all Valves again
before performing any procedure in this section.
TO PREVENT SERIOUS INJURY FROM TOOL FAILURE:
Do not use damaged equipment. If abnormal noise, vibration,
or leaking air occurs, have the problem corrected before further use.
Cleaning, Maintenance, and Lubrication
Note: These procedures are in addition to the regular checks and maintenance
explained as part of the regular operation of the air-operated tool.
1. BEFORE EACH USE, inspect the general
condition of the tool. Check for:
• loose hardware or housing,
• misalignment or binding of moving parts,
• cracked or broken parts, and
• any other condition that may
affect its safe operation.
2. Daily - Air Supply Maintenance:
Every day, maintain the air supply according
to the component manufacturers' instructions.
Drain the moisture filter regularly.
Performing routine air supply maintenance
will allow the tool to operate more safely
and will also reduce wear on the tool.
3. When re-using abrasive, sharp edges of abrasive
particles eventually become rounded and lose
cutting ability. At this point replace the abrasive.
4. The parts of the Blaster that require frequent
wear inspection and occasional replacement
are those that carry the air/abrasive mixture.
Pay particular attention to the Abrasive Hose,
Gasket, the Abrasive Valve, the Trigger Valve
and the Nozzles, as they will wear out much
more quickly than the other pieces.
CAUTION! Air leaks in any of the above mentioned
parts need to be repaired before use.
5. Abrasive Hose inspection:
When new, the Abrasive Hose has 1/4″ ID.
The Hose will need to be replaced when its side
walls develop leaks or show blisters on the surface.
WARNING! TO PREVENT SERIOUS INJURY: The
hose could have residual abrasive or suddenly
burst. Point the nozzle in a safe direction and
wear all safety gear when doing this test.
a. Close the Abrasive and Trigger Valves.
b. Adjust the air pressure to 90 PSI.
c. Open the Air Valve.
d. Open the Throttle Valve.
e. Then, run your fingers along the length of
the Hose. An enlarged spot (or bubble)
indicates a weakened section of the Hose.
Do not use the Blaster if this problem is
present - replace the entire Hose first.
6. To protect the compressor and its engine
or motor from damage by abrasive or dust
from Abrasive blasting, keep the compressor
up-wind of the Blaster or in a separate room.
Troubleshooting
1. Excess moisture will cause the abrasive to slow
or stop flowing through the Abrasive Outlet Pipe.
To correct, check the abrasive by pouring a 6″
cone of abrasive on dry newspaper. After several
minutes, remove the abrasive from the newspaper.
Do not use the abrasive if the newspaper is moist.
2. Poor or irregular flow of the abrasive may also
be due to low air pressure or a worn Nozzle.
To correct, increase the air pressure (to no more
than 125 PSI) and/or replace the worn Nozzle.

return repaired products at our expense, but if we determine there is no defect, or that the defect resulted
from causes not within the scope of our warranty, then you must bear the cost of returning the product.
