2. SPECIFICATION
Includes 1.4mm Nozzle (Assembled) for spraying and 2.0mm Nozzle for priming.
Required air pressure: 15-45 psi
Aluminium cup capacity: 1000ml
Air consumption: 9.5-14.8 cfm
Air inlet: 1/4”BSP
Includes air regulator valve and gauge
3. ASSEMBLY
1. Spray Gun
Ensure the strainer is inserted into the gun port with the stem outermost for easy removal.
Fit the cup and selected spray head, hand tight only.
2. Air Supply
Recommended hook-up is shown in Fig.A.
Ensure the spray gun air valve (or trigger) is in the off position before connecting to the air
supply.
You will require an air pressure of 50psi, and an air flow according to specification.
WARNING! Ensure the air supply is clean and does not exceed 50psi while operating the
spray gun. Too high an air pressure and/or unclean air will shorten the product life
due to excessive wear, and may be dangerous causing damage and/or personal injury.
Drain the air tank daily. Water in the air line will ruin the paint finish and damage the spray
gun.
Clean air inlet filter weekly.
Line pressure should be increased to compensate for unusually long air hoses (over 8
metres). The minimum hose diameter should be 1/4” I.D. and fittings must have the same
inside dimensions.
Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain
that all connections are secure.
3. Couplings
Vibration may cause failure if a quick change coupling is connected directly to the spray gun.

5
To overcome this, connect a leader hose to the spray gun. A quick change coupling may
then be used to connect the leader hose to the air line recoil hose (Fig.A and Fig.B).
4. OPERATION
Inspect tool before use, looking for damaged, loose, and missing parts. If any problems are
found, do not use tool until repaired.
Workpiece 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 path 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. Before spraying, mask nearby objects not being
sprayed and lay cloths (not included) on the floors.
NOTICE: Clean the Spray Gun IMMEDIATELY after EVERY use. Delayed or inadequate cleaning will
permanently clog the Spray Gun. Latex paint hardens quickly and permanently inside Spray Gun.

Note: This Spray Gun can be used for spraying oil-based or latex paints.
Paint Preparation and Filling
Note: Proper paint mixture is essential.Follow the manufacturer’s directions.
Most paints will spray easily if they are thinned properly.
2. Thin the paint according to manufacturer’s
directions and mix thoroughly.
3. Carefully strain the paint through a paint strainer or a
piece of cheesecloth.
4. Fill the Cup to 3/4 full. Close Cup.
5. Start the air compressor and set the regulator to needed
pressure.Do not exceed maximum air pressure.
6. Test the consistency by spraying on a piece of scrap
material. If it still appears too thick, add a very small
amount of thinner (not included) and mix thoroughly.
Use the proper thinner for the type of paint. Thin
CAUTIOUSLY. Proceed slowly, adding minimal amounts
at a time. DO NOT exceed the manufacturer’s thinning
recommendations.

Spraying Technique
IMPORTANT: Proper spraying technique is ESSENTIAL to achieve good results.
1. First, clean and prepare the Spray Gun according to the instructions under
Before First Use on page 5 and Spray Gun Setup Adjustment on page 6.
2. Keep the Spray Gun upright and at a right angle to the workpiece –
See Figure M and Figure N.
3. Using two hands, one to steady the Cup and the other to operate the Spray Gun,
aim Nozzle at the workpiece.
CAUTION: DO NOT STOP WHEN SPRAYING.Spraying materials will start to set and dry
as soon as they come in contact with the air. They will cause a permanent clog if not cleared
immediately. If discontinuing spraying for more than half an hour, turn off the air supply,
disconnect Cup from Gun Body and thoroughly rinse Cup and Gun Body with fresh, clean
water.
4. Pull Trigger slowly and move Spray Gun in parallel strokes to the workpiece. Keep the
distance from the workpiece at about 6”to 9”, depending on the flow adjustment and the
paint.
5. To avoid paint build up, start moving the Spray Gun before squeezing the Trigger.

9
When finished with the stroke, release the Trigger
while still moving the Spray Gun - see Figure O.
Doing this will produce a smoother finish.
Do not stop moving the Spray Gun while spraying.
If the Spray Gun stops even briefly while spraying
the paint will build up and run down the workpiece.
Note: The stroke speed, the Fluid Knob adjustment, and the distance from the workpiece,
will determine how much paint is being applied. Apply two thin coats rather than one thick coat.
CAUTION! Air hose fittings may get hot. Allow fittings to cool before disconnecting,
or wear gloves to prevent burns.
6. To prevent accidents, release trigger, detach air supply, safely discharge any residual air
pressure, and again release trigger after use.
7. Clean the Spray Gun IMMEDIATELY after EVERY use, in between coats, and when
it will be idle for more than 5 minutes.
Cleaning
WARNING! TO PREVENT FIRE, IF A FLAMMABLE SOLVENT NEEDS TO BE USED,
ADHERE TO THE FOLLOWING:
a. Follow solvent manufacturer’s clean up instructions and safety precautions.
b. Flush Spray Gun a full hose length from air compressor.
c. If collecting flushed solvents in metal container, transfer to nonmetal container, and flush
metal container.
d. Work far away from any ignition sources in a vapor free area.
e. Keep class ABC fire extinguisher nearby.
Solvent Selection
Follow the paint and solvent manufacturer’s recommendations for cleaning, solvent type, and
disposal.
IMPORTANT: Do not use mineral spirits with latex paints, doing so will make the paint very
difficult to remove.
After Every Use
1. Use solvent recommended by paint manufacturer.
2. Remove the Cup, along with any tubes or filters. Carefully scrape paint out of Cup. Dispose
of excess paint properly, then clean Cup and accessories with solvent.
3. Reduce air pressure to minimum, then fill the Cup with solvent and spray it through the Spray
Gun into the spent solvent container, while shaking the Spray Gun. Once the Cup is empty,
repeat the process until the solvent comes out clean.
4. Disconnect from the air source.
5. After disconnecting, point the Spray Gun into the spent solvent container and squeeze the
Trigger again to make sure no air remains.

10
Note: Do not immerse Spray Gun Body in solvent. Do not allow solvent to enter the air inlet.
6. Remove Nozzle by hand and soak it in solvent until it is clean. Use brush to remove any
paint.
Note: To prevent damage to the passages, do not use metal objects to clean the Nozzle.
7. Wipe down Spray Gun Body with a clean cloth and solvent.
8. Make sure all parts are free from residual paint.
9. If switching from oil-based to latex paint, after cleaning
with solvent, clean all parts with warm soapy water.
