Central Pneumatic 69724 Owner's Manual & Safety Instructions page 11

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.
General Operating instructions
WarninG! tO prEVEnt SEriOuS inJury: Wear
anSi-approved safety goggles and niOSH-approved
respirator under Safety Hood, and heavy-duty
canvas gloves, when operating the abrasive Blaster.
1. 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.
2. close the air Valve, abrasive Valve, and throttle
Valve, then connect and turn on the air supply.
3. Open the Air Valve and Throttle Valve.
The tank will begin to pressurize.
4. Check for any air leaks at the Filler
Cap and along all hose fittings.
a. If leaks are observed, shut off the air compressor.
b. Use the Safety Valve to release any remaining
pressure, close the Air and Throttle Valves.
c. Repair the leaks, then turn on the air
compressor and resume the operation.
5. Grip the Blast Gun firmly with both hands
and open the Abrasive Valve.
6. Point the Nozzle at the Workpiece so
that the abrasive will strike the surface
of the work at about a 45° angle.
7. Squeeze the Trigger Valve to release the abrasive.
note: The flow rate of the abrasive may
be irregular when the unit is first started.
Provided the abrasive is dry, the flow rate will
stabilize in approximately one minute.
8. Adjust the Abrasive Valve to increase or
decrease the abrasive flow rate.
9. Adjust the Throttle Valve to regulate the total
air flow and pressure at the Blast Gun.
nOticE: Do not attempt to regulate air/abrasive
mixture discharge rate with the trigger Valve.
Doing so will ruin it.
To stop in the middle of operation,
release the Trigger Valve.
Item 69724 For technical questions, please call 1-888-866-5797.
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.
cautiOn! tO prEVEnt inJury FrOM
tOOL Or accESSOry FaiLurE:
Do not exceed the tool's
maximum air pressure rating.
If the tool still does not have sufficient force
at maximum pressure and sufficient airflow,
then a larger tool may be required.
10. Move the Blast Gun in a circular or right
to left motion until you have achieved the
desired finish on the Workpiece.
note: The impact pattern of the blast is affected by the
output pressure and the distance from the Workpiece.
11. Periodically check the Water Trap for excessive
water build up. If necessary, hold a container
beneath the Water Trap and press the button located
at the bottom of the Water Trap to drain the water.
after Blasting:
WarninG! tO prEVEnt SEriOuS inJury:
Keep the Nozzle pointed in a safe direction
until the Blaster is completely shut down.
12. Disconnect the air supply.
13. Close the Air Valve, Abrasive Valve,
then the throttle valve.
14. Squeeze the Trigger Valve fully. Allow
abrasive and any compressed air to leave
the Nozzle. Release the Trigger Valve.
15. Open the Safety Valve to make sure
tank is not pressurized. Check that the
Pressure Gauge reads "0" PSI.
16. Disconnect the compressor air
hose from the Air Inlet.
17. If necessary, empty the Tank of remaining abrasive.
18. Clean external surfaces with a clean, dry cloth.
Then store indoors out of children's reach.
