INSTRUCTION MANUAL
DESCRIPTION:
ATD sandblasting equipment is designed for cleaning and removing rust, scale, paint and
dirt. It is the ideal method for stripping, polishing and etching projects. This equipment can
be used with abrasive powders and liquids. This model is equipped with the standard use
ceramic nozzle.
SAFETY WARNING & CAUTIONS:
Warning: When using pneumatic equipment, basic safety precautions should always be
followed to reduce the risk of personal injury and hazards due to over pressurization.
READ ALL INSTRUCTIONS BEFORE USING:
1. Keep work area clean. Cluttered areas invite injuries.
2. Observe work area conditions. Do not use unit in damp, wet or poorly lit locations. Don’t
expose to rain. Keep work area well lit. Do not use electrically powered air compressors
in the presence of flammable gases or liquids.
3. Keep children away. Children must never be allowed in the work area.
4. Do not use inappropriate attachments in an attempt to exceed the unit capacities.
5. Dress properly. Do not wear loose clothing or jewelry as they can be caught in moving
parts. Non-skid footwear is recommended. Always wear the hood (included), a dust
mask and heavy-duty canvas gloves.
6. Use eye and ear protection. Always wear ANSI approved chemical splash goggles
when working with chemicals. Wear an ANSI approved dust mask or respirator when
working around metal, wood and chemical dusts and mists.
7. Do not overreach. Keep proper footing and balance at all times. Do not reach over or
across running machines.
8. Keep machine clean for better and safer performance. Follow the instructions for
lubricating and changing accessories. Inspect compressors cord periodically and if
damaged have it repaired by a qualified technician. Inspect all hoses for leak prior to
use. The handle must be kept clean, dry and free from oil and grease at all times.
9. Be sure that keys and adjusting wrenches are removed from the unit or work surface
before using.
10. Make sure the air pressure adjustment is set at “0 PSI” and the shut off valve is in the off
position when not in use and before attaching the air compressor.
11. Do not operate the unit when tired or under the influence of alcohol or drugs.
12. Before using check for alignment and binding of moving parts, any broken parts or
mounting fixtures and any other conditions that may affect proper operation. Do not use
the unit if any switch does not turn on or off properly.
13. When servicing only use parts and accessories intended for use with this unit.
14. Drain water trapped in the air pressure adjuster periodically.
15. Do not allow sand blaster to be pressurized while unattended or not in use.
16. Make sure all equipment is rated to the appropriate capacity. Make sure that regulator is
set no higher than 125PSI.
17. Periodically check the abrasive medium delivery equipment. Valves, hoses and nozzles
that carry the abrasive medium after it leaves the pressure tank are subjected to the
sandblasting action and will wear out more quickly than other components.
18. Release the air pressure in the tank before opening. Open the shut off valve to release
pressure. Make sure pressure gauge reads “0 PSI” before opening the tank. Do not
attempt any repairs to the sandblaster until the gauge reads”0 PSI”.
19. Maintain correct air pressure whenever working. Do not allow pressure to exceed
125PSI. If the safety valve does not release excess air pressure, stop all work and open
the shut off valve to release pressure in the tank.

OPERATION:
WARNING:
Always wear your hood, dust mask and heavy-duty canvas gloves when operating.
1. Close the sand metering valve (#26), pour about 25 lbs of abrasive medium into the tank.
Then close the tank filler cap (#4) securely, assuring that o-ring (#3) is in place.
2. Turn the air pressure adjuster (#9) counter-clockwise (lowest pressure) fully. With the air
compressor off, attach the connector (#8) to an air supply hose coming from the air
compressor. Tighten securely with a hose clamp.
3. Switch on power to start up the air compressor. Check for leaks at the tank filler cap (#4)
and along all hoses and fittings as pressurization begins.
4. Turn the air pressure adjuster (#9) slowly clockwise until the pressure gauge reads a
desired value.
5. Open the sand metering valve (#26) and push down the control level of the sanding gun
(#24) to an appropriate position to gain a desired sand flow.
6. To shut the unit down, close the sand metering valve (#26) and turn the air pressure
adjuster (#9) counter-clockwise until the pressure gauge reads “0 PSI”. Push down the
control level of the sanding gun (#24) to release any extra air, and to be sure that the air
supply is off.

MAINTENANCE:
1. Keep your sandblaster clean and protect from damage.
2. Depressurize after using.
3. When initially pressurizing, check for leaks at the tank top and at all hoses and fittings.
Leaking joints may be repaired by replacing worn or damaged Teflon tape at joints.
4. Check for worn sand hose and fittings. The sand metering valve, manifold and all parts
after the sand is ejected from the tank are subject to rapid wear, due to the flow of
abrasive sand. Watch especially for leaks, blistering bulging or thinness of the hose.
Replace any parts which appear worn.
ABRASIVE SELECTION:
The kind of sand you choose will greatly influence the amount of time needed to clean a
given surface area. Sandblasting materials include silicon carbide, alumina, silica sand and
others.
Be sure that the sand you use is thoroughly dry. Damp sand can cause clogging of your
sandblaster.
While you may reuse abrasive sand, remember that sand does wear out. After using, sand
becomes smoother and rounder, thus reducing abrasive effectiveness.
Reusing abrasive sand may also cause clogging due to debris contained in the mixture
from prior use.
ABRASIVE FLOW ADJUSTMENT
Choose a larger nozzle for a broader spray pattern. Choose a smaller nozzle for more
focused sandblasting.
Adjust air pressure with the air pressure adjuster (#9). Adjust sand flow with sand metering
valve (#26).
Watch for sand clogging. Depressurize if necessary and replace the sand with drier or
cleaner abrasive.
SAFETY AND HEALTH CONSIDERATIONS
Before opening tank be sure that it is not pressurized. Be sure that the gauge reads ”0 PSI”.
Depressurize the tank before opening it by exhausting pressure through the sanding gun
(#24).
Disconnect the air compressor before opening tank.
Protect yourself and those around you from “overspray”. Remember that your portable
sandblaster is shooting a powerful spray of abrasive material. Do not point it at yourself or
anyone around you.
Wear a filter or mask over your mouth when using this unit. You will create a cloud of
abrasive material and debris which is dangerous to inhale.
Remove cover or protect anything around you that might be damaged from direct or indirect
contact with the abrasive spray or particles. Anything subject to contamination damage
(computers, electronics, etc) or anything with a fine surface (automobiles, furniture, etc.)
should NOT be near your sandblaster.
CAUTION:
1. Pay particular attention to the sand hose (#21), sanding gun (#24) as they will wear out
much more quickly than others pieces.
2. The sand hose needs replacing when its side walls develop leaks or show blisters in the
surface. Do not use if any of these problem are present.
