Some dust created by sand blasting contains chemicals known to the State of California to cause cancer, birth defects or
other reproductive harm. An example of this type of chemical is lead from lead based paints, Crystalline Silica from bricks
and cement or other masonry, Arsenic and Chromium from chemically treated lumber. Your risk from these exposures varies,
depending on how often you do this type of work. To reduce your exposure: work in a well ventilated area and work with
approved safety equipment, such as dusk masks that are specially designed to lter out microscopic particles.

IMPORTANT SAFETY INFORMATION
and perform its intended function. Check for alignment and binding of mov-
ing parts; any broken parts or mounting fixtures; and any other condition that
may affect proper operation. Any part that is damaged should be properly
repaired or replaced by a qualified technician.
14.Repairs should only be carried out by a qualified electrician using original
PERFORMANCE TOOLS® replacement parts. Failure to do so can lead to
accidents for the operator. Use of any other parts will void the warranty. Only
use accessories intended for use with this tool. Approved accessories are
available from Performance Tool®. Use only accessories that are recom-
mended by the manufacturer for your model. Accessories that may be suit-
able for one tool may become hazardous when used on another tool.
15.Do not operate any tool if under the influence of alcohol or drugs. Read
warning labels on prescriptions to determine if your judgment or reflexes are
impaired while taking drugs. If there is any doubt, do not operate any tool.
16.For your safety, maintenance should be performed regularly by a qualified

WARNING: Cancer and Reproductive Harm.
WARNING: The warnings, cautions, and instructions discussed in this
instruction manual cannot cover all possible conditions and situations that may
occur. It must be understood by the operator that common sense and caution
are factors which cannot be built into this product, but must be supplied by the
operator. Read and understand all of the instructions provided in the instruction
manual of this product, as well as, any other tool(s) used with this product.
1. Install an air regulator with pressure gauge and an in-line shuto valve in your air
line as near to your tool as possible for best service.
IMPORTANT: An in-line shuto valve is an important safety device because it con-
trols the air supply even if the air hose is ruptured. The shuto valve should be a
ball valve because it can be closed quickly.
2. Attach an air hose to the compressor’s air outlet. Connect the air hose to the air
inlet of the tool. Other components, such as a coupler plug and quick coupler,
will make operation more ecient, but are not required.
IMPORTANT: Do not install a female quick coupler on the tool. Such a coupler
contains an air valve that will allow the air tool to retain pressure and operate
accidentally after the air supply is disconnected.
IMPORTANT: The air hose must have the correct inner diameter for ecient air ow.
Usually an air hose of 3/8" inner diameter is recommended.

I MPORTANT: Apply thread sealant tape to all male threads in your air line for airtight
connection.
3. Close the in-line shuto valve between the compressor and the tool.
4. Turn on the air compressor according to the manufacturer’s directions and allow it
to build up pressure until it cycles o.
5. Adjust the air compressor’s output regulator so that the air output is enough to
properly power the tool, but the output will not exceed the tool’s maximum air
pressure at any time. Adjust the pressure gradually, while checking the air output
gauge to set the right pressure range.
IMPORTANT: An individual air tool has its specication of air consumption (CFM).
Check the specications of your air compressor to be sure that it can support both
minimum CFM (cubic feet per minute) and PSI (pounds per square inch) required.
An air hose (like 3/8" x 50 ft. air hose) may cause up to 15 PSI drop in pressure
from the air compressor to the tool, so you may need to set the output air pressure
of the compressor higher to maintain the required pressure at the tool.
AIR SUPPLY SETUP
1. Remove the hopper lid (1) and ll the hopper (2) with the provided
abrasive sand (3) in bottle. Ensure that you are not exceeding the
maximum ll level for the hopper of 17.2 oz. (Fig. 1)
IMPORTANT: Use the provided abrasive sand or other blasting medium which
does not contain silica. Heed the safety instructions provided by the manufac-
turer of the blasting medium.
IMPORTANT: Ensure that the blasting medium is totally dry and not too coarse-
grained. Moist or too coarsegrained blasting medium will clog the gun.
2. Replace the hopper lid once the hopper is lled.

TYPES OF ABRASIVES
WORK AREA SETUP
IMPORTANT: To keep the blasting medium from accidentally spilling out of the
nozzle, do not point the nozzle downward.
1. Designate a work area that is clean and well-lighted. 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 tr ipping hazard or exposing the air hose to possible damage.
The air hose must be long enough to reach the work area to allow free
movement while working.
3. If possible, place the workpiece inside an abrasive blasting cabinet
(not included). Otherwise, isolate the workpiece to make sure no damage
can occur to nearby walls, tools, equipment, or other property.
IMPORTANT: Prior to abrasive blasting, protect other people and/or property in
the work area from ying debris by providing barriers or shields. Wear appropri-
ate clothing and safety gear when operating the blaster gun.
Suitable abrasives for this spot blaster are:
- Black Aluminum Oxide
- Glass Beads
- Walnut Shells
- Silicon Carbide (Carborundum)
- Pumice
OPERATING INSTRUCTIONS
1. Connect the compressor’s air hose to the air inlet (4) of the blaster gun (5). It is
recommended that a male plug (not included) be rst mounted into the air inlet for
quick connection of air hose.
2. Turn the compressor on and set the working pressure to 90 PSI max. for the tool.
IMPORTANT: Working pressure refers to the air line pressure under working conditions.
3. Hold the blaster gun (5) rmly with both hands. Aim the nozzle (6) toward the work piece
to be blasted. Then squeeze the trigger (7) to start operating the blaster gun.
4. Move the blaster gun close to the area to be worked. The nearer you are to the
workpiece, the smaller the dispersion pattern and vice versa.
