SAFETY PRECAUTIONS
1. You as the owner of this Sand Injector are responsible for
the safety of the operator. Read and understand this manual.
Provide a copy to the operator as standard procedure.
2. Before attempting to install this injector, make sure the machine
is shut off and the pressure in the system is released (by
triggering the gun momentarily).
3. Protective goggles are supplied with this sand injector.
4. Always wear eye protection when using a pressure washer. Other protective clothing. i.e. rubber suits, rubber gloves,
respirator, etc. may be necessary. Read sand label for recommended precautions.
5. When using the injector with a pressure washer, the operator must be provided with an operator's manual for that
model and become acquainted with all the safety, installation and operational procedures provided therein.
OPERATION INSTRUCTIONS
Place the sand induction probe in the sand supply container.
Connect the mixing head to the spray wand. Start the machine per manufacturer’s instruction.
Trigger the gun to activate the spray.
Check the distance to hold the spray nozzle from the surface by starting to spray at a scrap of material from a distance of
several feet. Gradually move closer, checking frequently to see if the high pressure spray is damaging the surface.
Refer to the application table for the type of sand recommended for your work surface.
Always point the sand nozzle downward when not spraying. This will prevent water from entering the sand supply. If water
does get into the sand supply hose, remove the probe from the sand, hold control handle trigger open, and let the hose air
dry. Always be sure the sand hose is dry before using.
Keep the sand covered to prevent the overspray from wetting the sand. Do not allow small fragments of the sand bag to fall
into the sand supply. A small paper fragment could prevent the flow of sand.
After the sandblasting operation is complete, remove the probe from the sand, trigger the gun to clear the hose and probe
of sand. Then remove the hose from the mixing head and rinse with water to remove all the sand before storage.
APPLICATIONS
Sand Mesh: Sand mesh refers to the size of screen through which a particular grade of sand will pass. A 16/50 mesh means
that normally, most of the particles will pass through a
#16 screen and a very small percentage will pass through
a #50 screen.
Note: A #16 screen has 16 0.046 holes per square inch.
Round Sand: This refers to the round edge of the grain
of sand. River sand is a good example of sand worn to
its shape by water.
Angular Sand: This refers to grains of sand which have
triangular shaped edges. Crushed rock or sand is usually
of this type.
Blasting Angle and Distance: The blasting angle can
affect the sandblasting distance. For the best sandblasting
performance always maintain the recommended blasting
angle and the proper distance for your work surface.
