GENERAL SAFETY RULES

WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU
ARE THOROUGHLY FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE
USE OF COMPRESSORS AND COMPRESSED AIR SUPPLY.

1. Read this instruction manual before connecting the sandblaster to your compressor.

2. DO NOT use any silica based abrasives with this tool. Silica based abrasives have
been linked to severe respiratory disease. ALWAYS use recommended abrasives.
Abrasives used in this sandblaster may be covered by COSHH Regulations.

3. Read this manual carefully, Learn the sandblaster applications and limitations, as
well as potential hazards specific to it.

4. DO NOT expose to moisture. Don't use this product in damp or wet locations, Keep
out of rain.

5. Keep work area clean and well lit. Cluttered or dark work areas invite accidents.

6. Keep children away. All children should be kept away from the work area. Never let
a child handle tools without strict adult supervision.

7. DO NOT operate this product if under the influence of alcohol or drugs. Read
warning labels on prescriptions to determine if your judgment or reflexes are
impaired while taking medication. If there is any doubt, do not attempt to operate.

8. Use safety equipment. Dust mask, non-skid safety shoes, hard hat, or hearing
protection should be used in appropriate conditions.

9. DO NOT overreach, Keep proper footing and balance at all times when operating
this product.

10. ALWAYS disconnect the sandblaster from the air supply and release pressure from the
tank before storing, servicing, or changing accessories.

11. Use clamps or other practical means to secure and support the work piece to a
stable platform. DO NOT hold the work by hand or against your body.

12. DO NOT point the sandblaster at anyone or at any objects other than the intended
work object.

13. Check your sandblaster regularly for damage, If any part is damaged it should be
carefully inspected to make sure that it can perform its intended function correctly.
If in doubt, the part should be repaired. Refer all servicing to a qualified technician.
Consult your dealer for advice.

17. Drain the water trap periodically during use, Do not allow moisture to fill more than

Fig 1

Fig 2

1/2 of the water trap bowl. Do not leave water standing in the water trap when
storing the sandblaster.

18. DO NOT allow the sandblaster to sit pressurized while unattended or not in use.

19. Periodically check the abrasive medium delivery components. Valves, hoses and
nozzles that carry the abrasive medium after it leaves the pressure tank are
subjected to the abrasive blasting action so will wear out more quickly than other
components.

20. Release the air pressure in the tank before opening. See “Releasing Pressure from the
Tank” section, Make sure pressure gauge reads “0” before opening the tank. DO
NOT attempt any maintenance on the sandblaster until the pressure gauge reads
“0” and it has been disconnected from the air supply.

21. Maintain the correct air pressure whenever working. DO NOT allow working pressure
to exceed 125 psi. If the safety valve does not release excess air pressure, stop all
work and release pressure from the tank (see “Releasing Pressure from the Tank”
section).

22. ALWAYS make sure there is adequate ventilation. DO NOT work in confined areas.

23. In the case of injury seek expert medical advice immediately.

24. Use clamps or a vice to hold the work if it is small or of light weight rather than using
your hands. This frees both hands to operate the nozzle.

SAFETY AND HEALTH CONSIDERATIONS

• Before opening tank make sure that it is not pressurized. Ensure the gauge
reads “0”. If it does not, release pressure from the tank (See page 10).

• Disconnect the compressor before opening the tank. Protect yourself and
those around you from “over-spray”. Remember that your sandblaster is
shooting a powerful spray of abrasive material. Do not point it at yourself or
anyone around you.

• Wear protective clothing including hood (30), and heavy gloves when using
this sandblaster.

• Wear a dust mask over your mouth and nose when using this sandblaster. You
will create a cloud of abrasive material and debris which is dangerous to
inhale.

• Protect anything around you that may be damaged from the spray of
abrasive particles. Nothing subject to contamination damage or with a fine
surface should be near your sandblaster work area.

LOADING THE ABRASIVE

Fig 9

Fig 10

Fig 11

• To prevent clogging, ensure that the abrasive you use is dry.

• While you may re-use abrasive but remember that abrasive grit/material
does wear out. After use, abrasive becomes smoother and rounder, thus
reducing its effectiveness.

NOTE: Re-using abrasive may also cause clogging due to fine debris contained

in the mixture from prior use.

1. Close the air supply valve by turning it
to the closed position, see Fig 9.

2. Squeeze the trigger to release any
pressure from the tank.

• Make sure the pressure gauge

reads “0”.

3. Remove the filler cap.

4. Using the sieve and funnel supplied,
pour the selected abrasive material
into the tank, see Fig 10.

• Do not fill the tank more than ¾ full.

• If humidity in your region is 90% or

more, only fill the tank ½ full and
check the water trap more
frequently.

5. Replace the filler cap ensuring the O­ring is in place.

NOTE: Place your air compressor in another room to prevent damage from the

intake of abrasive dust laden air.

TO START BLASTING

NOTE: Start with all valves in the closed position. Following the instructions below

will help prevent clogging in the delivery hose, outlet manifold and in the
gun.

1. Connect the compressor to the inlet
connector.

2. Start the compressor and open the air
supply valve, see Fig 11.

the desired amount of abrasive
material is flowing through the gun.

9. Begin blasting.

ABRASIVE FLOW ADJUSTMENT

• Choose a larger nozzle for a broader spray pattern. Choose a smaller nozzle

for more focused spray.

• Adjust air pressure with the throttle valve. Adjust abrasive flow with the

abrasive control valve.

• Watch for abrasive clogging. Release pressure from the tank if necessary and

replace the abrasive with drier or cleaner abrasive.

TO STOP BLASTING

1. While continuing to press and hold the trigger, turn the abrasive control valve to the
closed position, see Fig 14.

2. When you notice only air (no abrasive) is coming out of the nozzle, you can stop the
air flow by releasing the trigger. By doing this you are ensuring a clean manifold,
hose and gun.

3. ALWAYS clean the gun thoroughly after use.
