WARNING
: To reduce the risk of injury, always
protect eyes and face with goggles and mask,
and hands and arms with heavy work gloves
when spraying abrasive materials.
1.
Connect lance of grit blast kit in to gun in place
of the vario lance.
2.
Place the sand probe in the sand container.
How To Sandblast :
1.
Connect and open the water supply line before
starting the pressure washer.
2.
Squeeze the gun trigger to release air in the
equipment.
3.
Turn on the pressure washer.
4.
Squeeze the gun trigger to activate the spray.
5.
CAUTION:
Always test spray on a scrap of
similar material first! The high pressure spray
could damage the surface if the grit blaster is
held too close.
To determine best distance for grit blasting, start
with the spray nozzle a metre away from the
surface and gradually move closer, frequently
checking the surface for damage.
6.
Always point the nozzle downward when not
spraying. This prevents water from entering the
sand supply. If water does get into the sand
supply hose, remove the probe from the sand,
hold the gun trigger open, and let the hose air
dry. Always be sure the sand hose is dry before
using.
7.
Keep the sand covered to prevent the overspray
from wetting the sand. Do not allow small pieces
of the sand bag to fall into the sand supply. A
smaller piece could prevent the flow of sand.
