DANGER!
Potential hazard that will result in serious injury or loss of life.
•
Keep children away from the work area. Do not allow children to handle
power tools.
•
Do not point the tool towards yourself or other people, even if the tool has
stopped. Keep hands, feet, and all other parts of the body clear from work
area.
•
Never use homogenate hydrocarbon solvent, which can chemically react
with aluminium and zinc parts and which is not chemically compatible with
aluminium and zinc parts.
•
Do not use this tool in the presence of flammable liquids
or gases. Sparks that are created during use may ignite
gases. Please use the tool in well-ventilated area only
and avoid any ignition sources such as smoking and open
flames.
MC-OM-05
•
Do not use oxygen or any other combustible or bottled
gas to power air-powered tools. Failure to observe this
warning can cause explosion and serious personal injury
or death. Use only compressed air to power the air-powered tools. Use a minimum of 25' (7.6 m) of hose to connect the tool to the compressor. Failure to comply will
result in serious injury or loss of life.

MC-OM-02
•
Risk of electric shock: Do not expose a compressor to rain. Store it indoors.
Disconnect the compressor from power source before servicing. Compressor
must be grounded. Do not use grounding adaptors.
•
Risk of personal injury: Do not direct compressed air from the air hose
towards the user or other persons.
AIR-POWERED SIPHON-FEED SPRAY GUN 058-9336-2
•
Risk of inhalation: Never directly inhale the air produced by the compressor
and the spray gun. Always use the spray gun in a well ventilated area.
Use protective respirator: Toxic vapors produced by spraying certain materials can cause serious damage to health.
Always wear safety es, gloves, and respirator to prevent the
hazard caused by inhalation of toxic vapor or contact of solvent and paint with eyes or skin. Failure to comply will result
in moderate injury.
MC-OM-04
•
Risk of burns: The pump and the manifold generate high temperatures. In
order to avoid burns or other injuries, do not touch the pump, the manifold,
or the transfer tube while the compressor is running. Allow the parts to cool
down before handling or servicing. Keep children away from the compressor
at all times.
•
Risk of bursting: Do not adjust the pressure switch or
safety valve for any reason. They have been preset at the
factory for this compressor’s maximum pressure.
Tampering with the pressure switch or the safety valve
may cause personal injury or property damage. Make
sure the regulator is adjusted so that the compressor
outlet pressure is set lower than the maximum operating
pressure of the tool. Before starting the compressor, pull
the ring on the safety valve to make sure the valve
moves freely. Drain water from tank after each use. Do
not weld or repair tank. Relieve all pressure in the hose
before removing or attaching accessories.
•
MC-OM-22
Use compressed air at regulated pressure: Always use
clean, dry, and compressed air at regulated pressure. Do
not exceed the maximum operating pressure of 8.3 bar
(120 PSI). Failure to comply will lead to serious injury or
loss of life.

WARNING!
Potential hazard that could result in serious injury or loss of life.
•
Do not allow unskilled or untrained individuals to operate the Air-powered
Siphon-feed Spray Gun.
•
Use components recommended by manufacturers: Never modify the tool for
other applications. Use only parts, nozzles, and accessories with
specifications as mentioned in this manual (see section “Technical
specifications”).
•
Some solvents and chemicals used in the spray gun may pose a risk of
personal injury or death, or may pose a threat to the environment. The
operator should read the associated Material Safety Data Sheet (MSDS),
understand all warnings, wear suitable personal protective equipment, and
follow safe handling and application procedures, before using the spray gun.
•
Inspect the tool components and attachments before operation and ensure
that they are assembled properly and are not damaged. Failure to comply
will lead to serious injury or loss of life.
•
Locate the compressor in a well-ventilated area for cooling, a minimum of
12" (31 cm) away from the nearest wall.
•
Protect the air hose and the power cord from damage and puncture. Inspect
them for weak or worn spots every week, and replace them if necessary.
•
Always wear hearing protection when using the air compressor. Failure to do
so may result in hearing loss.
•
Do not carry the compressor while it is running.
•
Do not operate the compressor if it is not in a stable position.
•
Do not operate the compressor on a rooftop or in elevated position that
could allow the unit to fall or be tipped over.

CAUTION!
Potential hazard that may result in moderate injury or damage to
equipment.
•
Keep proper footing at all times in order to ensure correct balance.
•
Do not use a tool that is leaking air, with missing or damaged parts, or that
requires repairs. Verify that all screws are securely tightened.
•
For optimal safety and tool performance, inspect the tool daily in order to
ensure free movement of the trigger, safety mechanisms, and springs.
•
Ensure proper tool operation before painting. Before painting, inspect to
ensure free movement of the trigger and nozzle.
•
Check the tightness of screws before operating the tool. Before operating
the tool, make sure all the screws and caps are securely tightened to
prevent leakage.
•
Keep the work area clean. A cluttered or dirty workbench may lead to an
accident. Floors should be kept clear.
•
Handling and storage of oil: Use with adequate ventilation. Avoid contact of
oil with eyes, skin, and clothing. Avoid breathing spray or mist. Store in a
tightly closed container in a cool, dry, well-ventilated area free from
incompatible substances.
•
Do not use the tool near or below freezing temperatures, as doing so may
cause tool failure.
•
Do not store the tool in a freezing environment to prevent ice formation on
the operating valves of the tool, as that may cause tool failure.

IMPORTANT INFORMATION
Compatible compressors and air tool
GUIDELINES FOR PROPER USE AND OPERATION
Be sure to use the proper air compressor with Mastercraft® air-powered tools. The compressor
should be able to supply a minimal air delivery of 7.1 SCFM @ 51PSI to ensure the compressor can
run continuously with the Mastercraft Air-powered Siphon-feed Spray Gun. Using tools or
combinations of tools that together or separately require more than the air compressor can deliver
will reduce performance and could void the compressor or tool guarantee/warranty.

General Description
This Mastercraft® Air-powered Siphon-feed Spray Gun operates at 37 PSI (low pressure). The spray
gun uses an air cap which forms a easily-controllable soft spray and generates less overspray and
high transfer efficiency. The spray gun has adjustable knobs to control paint output, pattern
formation, and air outflow. This spray gun is designed to provide uniform atomization and particle
size for painting any type of surface. The stainless steel needle, nozzle, and precision air cap setting
are provided for a variety of coatings. The lightweight, ergonomic design and easy trigger pivot
enable user-friendly operation, reducing operator fatigue.

WARNING!
Potential hazard that could result in serious injury or loss of life.
•
Do not exceed the maximum pressure of spray gun or any other parts in the
compressor system. Failure to comply could lead to serious injury or loss of life.
•
Never aim or spray at yourself or anybody else which could cause serious
injury. Failure to comply could lead to serious injury or loss of life.
•
After unpacking the spray gun, inspect
carefully and check thoroughly to see if
there is any damage that may have
occurred during transit. Ensure the
tightness of fittings, bolts, etc., before
performing any operation.
•
After connecting the gun to air supply,
ensure the tight connection of the fluid
cap, canister, and air hose with the Airpowered Siphon-feed Spray Gun.
•
Use a piece of cardboard or other scrap
material as target for trial spray and
adjust for best spray pattern.
