14. Do not attempt to operate this product near flammable materials or
combustibles. Failure to comply may cause serious injury.
15. Always make sure that the trigger is not on before connecting the
sandblaster to the air supply.
16. Store idle equipment out of the reach of children and untrained persons.
Tools may be dangerous in the hands of untrained users.
17. Drain the water trap periodically during use, Do not allow moisture to fill
more than 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 light weight rather than
using your hands. This frees both hands to operate the nozzle.
ENVIRONMENTAL PROTECTION
Recycle unwanted materials instead of disposing of them as waste.
All tools, accessories and packaging should be sorted, taken to a
recycling centre and disposed of in a manner which is compatible
with the environment.

OPERATION
SAFETY AND HEALTH CONSIDERATIONS
• Before opening the tank make sure it is not pressurized. Ensure the
pressure 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 protective hood and heavy
gloves when using this sandblaster.
• Wear a dust mask over your mouth 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.
WARNING: ALWAYS WEAR YOUR HOOD, DUST MASK AND HEAVY DUTY
CANVAS GLOVES WHEN OPERATING THE SANDBLASTER.
WARNING: BEFORE OPERATING YOUR SANDBLASTER, INSPECT EACH
CONNECTION, DOUBLE CHECKING TO MAKE SURE THAT ALL ARE TIGHT
AND PROPERLY SEALED.

ABRASIVE SELECTION AND LOADING
The type of abrasive you choose will greatly influence the amount of time
needed to clean a given surface area. See page 12 for suitable abrasives.
• 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. With 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 medium from prior use.
4. Close the air supply valve by
turning it to the closed position,
see Fig 8.
5. Squeeze the trigger to release any
pressure from the tank.
• Make sure the pressure gauge
reads “0”.
6. Remove the filler cap.
7. Using the sieve and funnel
supplied, pour the abrasive
material into the tank, see Fig 9.
• 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.
8. Replace the filler cap ensuring the
O-ring is in place.
NOTE: Position your air compressor
in another room to prevent damage from the intake of abrasive
dust laden air.
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.
