ATD-8401

40 LBS. PRESSURE BLASTER

INSTRUCTION MANUAL

ATD abrasive blasting 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: Airborne dust: This is one of the most serious hazards associated with blasting

operations. When evaluating this hazard, it's important to consider the concentration of dust and the
size of particles. Larger particles, considered "nuisance" dust, are normally filtered out in the nose
and throat. Smaller particles (10 microns or smaller) can bypass the lung's filtering system and
penetrate deep into the respiratory system, where they may cause serious damage. Safeguards are
needed when smaller particles are present in the working environment.

Metal dust, in addition to the abrasive being used, contributes to the generation of airborne dust.
Metals such as lead, cadmium, and manganese, can be extremely toxic when inhaled. Many
existing paints have a lead base. Regulations require special handling, trained personnel, and
medical monitoring when lead is present. If in doubt, check it out. Don't guess.

Silica sand: This product is a potentially serious health hazard and should NOT be used as an
abrasive. If silica containing (quartz) materials are selected for any reason, workers must wear a
positive pressure or pressure demand respirator with an assigned protection factor (APF) of either
1000 or 2000. Silica must be contained and disposed of properly. Even if a wet blasting method is
selected, silica that is allowed to migrate by either wind or water, will eventually become an airborne
contaminant.

Air supply: Air-supplied respirators must be used (1) when working inside of blast cleaning rooms,
(2) when using portable units in areas without enclosure, and (3) under any circumstances where
the operator is not physically separated from the abrasive material by an exhausted enclosure. If
airline respirators and compressors are used, make sure the intake hose is placed in an area that
provides clean air. An attendant should be in the area at all times, monitoring breathing air and
assuring the blaster's safety.

Additional personal protective equipment: Blasting operations create high noise levels, so
hearing protection is a must--for both the operator and nearby workers! Operators should also use
heavy canvas or leather gloves, aprons, or leggings when appropriate, as well as safety shoes.

Handling and storing abrasives: Dust is nearly always created at any point where abrasives are
transferred, whether by hand or shovel. Therefore, all points of transfer must be properly exhausted
and workers who handle abrasives manually should wear particulate filter respirators.

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.

WARNING: Some dust created by abrasive blasting, grinding, and other construction activities

contains chemicals known to the State of California to cause cancer, birth defects, or other
reproductive harm. Your risk from exposure varies, depending on how often you do this work. To
reduce your exposure to these chemicals: work in a well-ventilated area, and with approved safety
equipment, such as dust masks that are specifically designed to filter out microscopic particles.

WARNING: Always wear eye protection that complies with a recognized standard (CSA or ANSI)

when operating or performing maintenance on this tool. User and bystanders.

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 pressure 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 abrasive
blasting action and will wear out more quickly than other components.

18. Release the air pressure in the t ank before opening. Open th e shut off valve to release pressure.

Make sure pressure gauge reads “0 PSI” before opening the tank. Do not attempt any repairs to
the pressure blaster until the gauge reads”0 PSI”.

19. Maintain correct air pressure whenev er working. Do not allow pressure to exceed 125 PSI. If the

safety valve does not release excess air pressure, stop all work and op en the shut off valve to
release pressure in the tank.

WARNING: The warnings and cautions discussed in this instruction manual cannot cover all

possible conditions and situations that may occur. It must be understood by the operator that
common sense and caution are factors that cannot be built into this product but must be supplied by
the operator.

ASSEMBLY:

NOTE: Use Teflon pipe tape on all threaded joints. Make sure all joints are securely tightened.

Legs, Wheels and Handle Bar Assembly (Refer to Fig 1):

1. Attach both the left leg (#7) and the right leg (#17) to the tank (#15) using the four screws & nuts.
The bottom section of the two legs must point outward respectively and the holes in the bottom
of the legs must be parallel to each other to accommodate the axle (#25).

2. Attach one of the wheels (#16) to the axle (#25) using one of the cotter pins (#14).

3. Slide the axle through the holes in the bottom of the two legs, using four cotter pins (#14) to fix
the position of the axle.

4. Attach the other wheel (#16) to the axle (#25) using the remaining cotter pin (#14).

5. Slide the handle bar (#6) onto the left leg (#7) and the right leg (#17) and secure it with two
