Work Piece and
Work Area Set Up
1. Designate a work area that is clean and well-lit.
The work area must not allow access by children
or pets to prevent distraction and injury.
2. Route the air hose along a safe route to reach
the work area without creating a tripping hazard
or exposing the air hose to possible damage.
The air hose must be long enough to reach
the work area with enough extra length to
allow free movement while working.
3. There must not be hazardous objects (such
as utility lines or foreign objects) nearby that
will present a hazard while working.
CAUTION! Prior to sandblasting, protect other
people (and property) in the work area from
flying debris by providing barriers or shields.
Always wear appropriate clothing and safety
gear when operating the Abrasive Blast Gun.
General Operating Instructions
1. If possible, place the workpiece inside a sandblast
cabinet (not included). Otherwise, isolate the
workpiece to make sure no damage can occur to
nearby walls, tools, equipment, or other property.
2. Fill the Container (3) with 1 liter of clean, dry blasting
media. Walnut Shells (SKU 92155 and 92150)
or aluminum oxide (SKU 99945) are available at
Harbor Freight Tools. WARNING! Do not use sand
as blasting media as sand may clog blast gun and
damage the nozzle. Do not reuse blasting media.
3. Place the Gun Body (1) on top of the Container and
turn clockwise until fastened securely.
NOTE: To keep the beads from accidentally spilling
out, do not point the Gun Body downward.

Body. Turn the compressor’s regulator to between
90-145 PSI. WARNING! Do not exceed 145 PSI.

the Blast Gun on a piece of scrap material.
6. Aim the Gun Body toward the object that
is to be sandblasted. Then squeeze the
trigger to turn on the Blast Gun.
7. Adjust the flow of abrasive media by
turning the knurled adjustment ring on the
nozzle. Turn clockwise to reduce flow and
counterclockwise to increase flow.
8. Use the Hook (4) to hang the Blast Gun
during use, if desired. WARNING! Do not
leave Blast Gun hanging unattended.

trigger. Turn off the air compressor and squeeze
the Trigger once again to release any compressed
