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 of 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.

ABRASIVE SELECTION
The type of abrasive you choose will greatly influence the amount of time
needed to clean a given surface area.
Suitable Abrasives available from your clarke stockist
LOADING THE ABRASIVE
• 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 ½full
and check the water trap more
frequently.
