footing and balance at all times.
Do not reach over or across
running tools or air hoses.
Disconnect air hoses and
release any built-up pressure.
Never service or disassemble
the air sander with the air hose
attached. Always release any
built-up air even after
disconnecting the hose.
Disconnect the air sander when
not in use.
Avoid unintentional starting.
Be sure the trigger is in the OFF
position before connecting the
air supply. Do not carry the tool
with your finger on the trigger,
whether it is attached to the air
source or not.
Stay alert. Watch what you are
doing and use common sense
when operating this tool. Do not
use this tool while tired or under
the influence of drugs, alcohol,
or medication. A moment of
inattention while operating this
tool increases the risk of injury.
Use clean, dry, regulated,
compressed air at 90 PSI.
Never use oxygen, carbon
dioxide, combustible gases, any
other bottled gas as a power
source for this tool.
Check for damaged parts.
Before using any tool, any part
that appears damaged should be
carefully checked to determine
that it will operate properly and
perform its intended function.
Check for misalignment or
binding of moving parts,
breakage of parts, and any other
condition that may affect the
tool’s operation. If damaged,
have the tool serviced before
using. Do not use the tool if the
trigger does not operate properly.
Replacement parts and
accessories. This product is to
be serviced by a qualified
technician. When servicing, use
only identical replacement parts.
Only use accessories intended
for use with this tool. Use of any
other parts will void the warranty.
Maintenance. For your safety,
this product should be serviced
or repaired regularly by a
qualified technician.
Do not operate the spray gun
near open flames, pilot lights,
heaters, or any other heat
source. Make sure you have
adequate ventilation. Most
solvents and paints are
extremely flammable, especially
when sprayed. Never smoke
cigarettes in the same room you
are working in.
Paints and solvents may be
harmful or fatal if swallowed or
inhaled. Always use a respirator
when spraying. Avoid prolonged
skin contact with solvents or
paints as they will irritate skin.
After contact, immediately wash
off exposed
area with hot, soapy water.
Check all spray gun seals and
connections. Before use, make
sure the lid is fully tightened on
the cup, ensure that the screws
and nuts are correctly tightened,
and make sure the air hose is
securely fastened and does not
leak.
WARNING
Never point the paint gun at
yourself or any other person or
animal. Solvents and diluting
agents can cause burns.
WARNING
The warnings, cautions, and
instructions discussed in this
instruction manual cannot
possibly cover all conditions and
situations that may occur. It must
be understood by the operator
that common sense and caution
are factors that cannot be built
into this product, but must be
supplied by the operator.
OPERATION
1. Fluid cup, container, and air
hose should be connected
tightly to the spray gun.
2. Adjust the air pressure
according to the viscosity and
type of paint. An air pressure
between 50 and 90 PSI is
recommended.
3. A spraying distance of 10
inches is recommended.
ADJUSTMENTS

atomization can easily be
obtained by regulating the
pattern adjusting knob and fluid
adjusting knob.
1. Adjusting pattern:
•Turn the pattern adjusting
knob to the left will make the
spray pattern wider.
2. Adjusting the volume of
fluid output:
•Turning the fluid adjusting
knob clockwise will reduce
the volume of fluid output,
and turning it
counterclockwise will
increase fluid output.
CLEANING AND
MAINTENANCE
•Be extremely careful not to
damage the air cap, fluid
nozzle, or fluid needle.
•Use the brush with thinner to
clean the air cap, fluid nozzle,
and other parts. Never immerse
the spray gun completely in
thinner or solvent.
•Spray thinner to clean out the
paint passageway.
• When reassembling, always
clean the tool in order to
prevent dust from sticking.
•The packing seat should not
be tight enough that it interferes
with the free movement of the
needle, but secure enough to
prevent leakage.
