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 Blaster. 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 manufacturer's 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 tool that require frequent
wear inspection and occasional replacement
are those that carry the air/abrasive mixture.
Pay particular attention to the Abrasive Hose,
O-Ring, Abrasive Valve, 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 Abrasive Hose will need to be
replaced when its side walls develop
leaks or show blisters on the surface.
WarninG! tO prEVEnt SEriOuS inJury: the
abrasive 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 air Valve, abrasive Valve, throttle
Valve, then release the trigger Valve. then
connect and turn on the air supply.
b. Adjust the air pressure to 60-125 PSI.
c. Open the Air Valve.
d. Open the Throttle Valve.
e. Then, run your fingers along the length
of the Abrasive Hose. An enlarged
spot (or bubble) indicates a weakened
section of the Abrasive Hose. Do not use
the Blaster if this problem is present -
replace the entire abrasive Hose first.
6. To protect the compressor and its engine
or motor from damage by abrasive or dust
from abrasive blasting, keep the compressor
upwind of the Blaster or in a separate room.
7. Daily - air Supply Maintenance:
Every day, maintain the air supply according
to the component manufacturer's 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.
