FOR SAFE OPERATIONS:
1. Keep work area clean
Cluttered or dark areas and benches invite accidents.
2. Consider work area environment
Do not operate power tools in explosive atmospheres, such as in the presence of flammable
liquids, rain, gases or dust. Keep work area well lit. Avoid working with power tools in damp
or wet areas or when perspiring. Store tools away from moisture. Do not use power tools
where there is risk to cause fire or explosion. Power tools create sparks which may ignite
the dust or fumes.
3. Guard against electric shock
Avoid body contact with earthed or grounded surfaces (e.g. pipes, radiators, ranges,
refrigerators).
4. Store idle tools
When not in use, tools should be stored in a dry, high or locked up place, out of reach of
children.
5. Do not force the tool
It will do the job better and safer at the rate for which it was intended.
6. Dress properly
Rubber gloves and non-skid footwear are recommended when working outdoors.
7. Do not abuse the cord
Never carry the tool by the cord or yank it to disconnect it from the socket.
Keep the cord away from heat, oil and sharp edges.
8. Do not overreach

22. A-weighted sound power level:96.3 dB(A).
23. Hand-arm vibration emission value: 0.582 m/s2.
CAUTION:
HAZARD: Solvent and paint fumes can explode or ignite, causing property damage and
severe injury. Avoid all ignition sources such as static electricity sparks,
open flames, pilot lights, cigarettes, etc.
HAZARD: Paints, solvents, insecticides and other materials may be harmful if inhaled
causing severe nausea, fainting or poisoning.
HAZARD: Do not hold cord at plug connections to support cord. Failure to observe may
result in an electric shock.
TREATMENT: See a physician immediately.
Notes:
 Practice before painting. Practice spraying water on cardboard, and adjust the paint
flow and turn the wings of the tip to get the desired spray pattern. (see Page 8 & 9.)
 Keep spray tip and needle clean.
Check spray tip and needle for dried paint before each use.
 Make sure paint tube is inserted tightly into the intake port.
 Always clean the sprayer after each use. (see Clean Up, page 11.)

SERVICING OF A DOUBLE-INSULATED PRODUCT:
In a double-insulated product, two systems of insulation are provided instead of
grounding. No grounding means is provided on a double-insulated product, nor should a
means for grounding be added to the product. Servicing of a double-insulated product
requires extreme care and knowledge of the system, and should be done only by qualified
service personnel. Replacement parts for a double-insulated product must be identical to
those parts in the product.
The double-insulated product shall be marked with « DOUBLE INSULATION » or «DOUBLE
INSULATED » and « ».
PAINT PREPARATION:
Most oil-based paint should be thinned with thinner before
spraying. (Figure A) It might include dry paint particles which
could block the spray tip. Strain the paint after thinning. Strain
the paint through a fine metal sieve or nylon stocking to remove
particles or fibers which could block the spray gun. (Figure B)
When spraying lumps, no spray or thick spray pattern, it might be
necessary to thin paint to achieve optimum spray pattern.
THE IDEAL CONSISTENCY FOR VARIOUS PAINTS:
Water based paint 20-35 sec.
Oil-based paint 20-30 sec.
Coating 20-30 sec.
Enamel paint 20-25 sec.
Wood stain 20-30 sec.
Metallic Paint 20-30 sec.
Clear Sealer No thinning required
Polyurethane No thinning required
Primer 30-45 sec.
Stain No thinning required
Varnish 20-45 sec.
* This guide can offer only general information.
Thinning should be followed according to the stain or paint manufacturer’s guideline.

OPERATING:
Adjust the Air-Cap
Slacken off the air-cap nut, turn the air-cap
to the required position to produce a
horizontal or vertical or round spray pattern.
The horizontal spray is generally used when
painting up and down, and vertical spray when
painting across, and round spray when painting
on the strip.
Adjust the paint flow
The knob adjusts the amount of paint released through
the nozzle. Turn the paint control knob clockwise,
the released flow becomes larger; turn it counterclockwise
for less flow. Adjust it until you get a desired spray pattern.
Air Blowing Nozzle
It is a breeze dusting device, suitable
for the use of dusting computer mainframe
heat sinks, keyboards, air conditioner
filter meshes, and all kinds of
precision instruments.
However, it is not suitable
for liquid spraying.

HOW TO OPERATE YOUR SPRAY GUN PROPERLY?
1. Practice before painting- Test your sprayer on cardboard or
scrap wood especially when you operate the sprayer first
time. 15 – 20 cm (6 – 8 inches) is about the best distance for
spraying. (Figure A)
2. Always hold spray gun upright and spray parallel to the
painting surface. (Figure B)
3. When spraying overhead (e.g. ceilings) or floors, be sure to
adjust the angle of suction tube; or the sprayer may fail to
get the paints from the container due to tilting. The vertical
inclination should be not more than 70° to avoid paints
running up into the head of the gun through the air-cap.
(Figure C)
4. The warm air from sprayer might cause the paint dried on
the spray tip and needle tip easily, so always keep the brass
needle clean with wet tissue or cloth to enable it to
work longer. (See Figure D)
5. If the motor doesn’t stop running or the needle is not
flexible, pull and release trigger quickly (2-3 times) to make
the needle back in the proper place. And use lubricant oil on
these 2 positions. (See Figure E & F)
6. If the paint could not be sprayed out, clean holes on each
side of pickup tube and the spray tip.
(See Figure G & H)

CLEANING UP
After the project has been completed or when you are going to take a longer rest, it is all
necessary to clean up the gun to prevent the paint from dried out and causing damage to
the gun.
Cleaning steps
1. Unplug sprayer from electrical outlet and empty the remaining material in the
container. (Figure A)
2. Fill container with some solvent (for oil-based paints) or soapy water (for water-
based paints).
3. Plug sprayer into an electrical outlet then spraying towards the recycling bucket for
about one minute (can’t spray towards the flammable area) till the paint inside the
circuit is fully cleaned. (Figure B)
4. Unplug sprayer and discard the remaining cleaning solution.
5. Disassemble nut, air-cap, suction tube, cup, etc. Clean up them with the above
cleaning solution thoroughly and then reassemble all parts to the gun. (Figure C)
6. Put a small amount of light oil such as WD-40 or 3-in-one etc. into the below position
(See page 8. Figure E & F) and trigger sprayer briefly. Always clean and lubricate
piston and cylinder after spraying your sprayer with water or paint for avoiding rust.
(See page 8. Figure E & F)
7. Clean the unit not enough and lubricate it with no lubricating oil which will cause
cylinder rusted to seize, failure to follow the above steps will void your guarantee.
Clean Air Filter
Clean or replace air filter periodically. An excessively dirty
filter might cause damage to the sprayer, and ensure
adequate ventilation at all time while using the unit.
