WARNING! Read all safety warnings and all instructions. Failure to follow the
warnings and instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-operated (corded) power tool
or battery-operated (cordless) power tool.
1) Work area safety
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools create sparks which may ignite the
dust or fumes.
c) Keep children and bystanders away while operating a power tool. Distractions can
cause you to lose control.
2) Electrical safety
a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not
use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and
matching outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces, such as pipes, radiators,
ranges and refrigerators. There is an increased risk of electric shock if your body is
earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the
power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or
entangled cords increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension cord suitable for outdoor
use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
f) If operating a power tool in a damp location is unavoidable, use a residual
current device (RCD) protected supply. Use of an RCD reduces the risk of electric
shock.
3) Personal safety
a) Stay alert, watch what you are doing and use common sense when operating a
power tool. Do not use a power tool while you are tired or under the influence of
drugs, alcohol or medication. A moment of inattention while operating power tools
may result in serious personal injury.
b) Use personal protective equipment. Always wear eye protection. Protective
equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection
used for appropriate conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the off-position before
connecting to power source and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or energising power tools that
have the switch on invites accidents.
d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a
key left attached to a rotating part of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables better

control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing
and gloves away from moving parts. Loose clothes, jewellery or long hair can be
caught in moving parts.
g) If devices are provided for the connection of dust extraction and collection facilities,
ensure these are connected and properly used. Use of dust collection can reduce
dust-related hazards.
4) Power tool use and care
a) Do not force the power tool. Use the correct power tool for your application.
The correct power tool will do the job better and safer at the rate for which it was
designed.
b) Do not use the power tool if the switch does not turn it on and off. Any power tool
that cannot be controlled with the switch is dangerous and must be repaired.
c) Disconnect the plug from the power source and/or the battery pack from the power
tool before making any adjustments, changing accessories, or storing power
tools. Such preventive safety measures reduce the risk of starting the power tool
accidentally.
d) Store idle power tools out of the reach of children and do not allow persons
unfamiliar with the power tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalignment or binding of moving parts, breakage
of parts and any other condition that may affect the power tool’s operation. If
damaged, have the power tool repaired before use. Many accidents are caused by
poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc. in accordance with these
instructions, taking into account the working conditions and the work to be
performed. Use of the power tool for operations different from those intended could
result in a hazardous situation.
5) Service
Have your power tool serviced by a qualified repair person using only identical
replacement parts. This will ensure that the safety of the power tool is maintained.

NOTE: Before using the tool, read the instruction book carefully.
Intended Use
The spray gun is for spraying non-flammable and non-hazardous paints and varnishes
suitable.
NOTE:
•This tool is suitable for solvent-based and water-based paints, finishes, primers, two-
component paints, varnishes, automotive topcoats, stains and wood preservatives.
•It is not suitable for alkali, acidic paints and the paints of which flash point is under 21.
WARNING! The tool cannot be used for spraying of flammable liquids. Do not use the
tool for the food, pharmacy or other purposes that are not mentioned in the manual.
PREPARATION
To obtain the best results, it is important that you prepare the paint to be sprayed and
thin the paint to the correct viscosity. Before operating, always ensure that the paints to
be sprayed are free from dust, dirt and grease. The paint or fluid to be sprayed should
be thoroughly mixed and free from lumps or other particles. Many substances can be
sprayed with your spray gun, but always check the manufactures recommendations before
purchasing your paint.
1. VISCOSITY MEASUREMENT
Most paints are supplied ready for brush application and will need to be thinned before
they are suitable to be sprayed. Follow the manufacturer’s advice on thinning the paint
when used with a spray gun. The viscosity cup will help you to determine the correct
viscosity of paint to be used.
To determine the correct viscosity (See Fig. A)
1) Stir well the paint before the starting to measure.
2) Fill the viscosity cup to the brim with paint.
3) Measure the time in seconds of liquid dripping from the cup into the can until the cup is
empty. The measured time is called run-DIN-seconds (DIN-s).

Operating Instructions
The table below shows recommended run-DIN-seconds for different types of material.
Solvent-based paints--------------------------------15-50
Primers---------------------------------------------25-50
Pickling----------------------------------no need to dilute
2 Component paints--------------------------------20-50
Varnishes------------------------------------------15-40
Waterborne paints---------------------------------20-40
Automotive topcoats--------------------------------20-40
Wood preservatives---------------------no need to dilute
If the paint takes longer than the recommended time to empty, then further thinning
is required. Mix in a small quantity of the appropriate thinner and use the viscosity test
until the correct thickness is achieved.
2. ASSEMBLING THE TANK
1) Remove the tank by unscrewing it in clockwise direction from the spray gun.
2) Fill the tank with paint of the correct viscosity.
3) Adjust the suction pipe direction correctly according to different operating conditions
to deplete the material in the tank as much as possible.
SPRAYING WITH A TILTING ANGLE:
Note: Don’t tilt too much.
Spray to the underlying objects
- turn the suction pipe forwards. (SEE FIG. B1)
Spray to the overhead objects
- turn the suction pipe backwards. (SEE FIG. B2)
4) Fill the tank with prepared paint.
5) Assemble the tank back to the spray gun by screwing it tightly in counter-clockwise
direction.

Operating Instructions
OPERATION
1. ON/OFF SWITCH (SEE FIG. C)
To start the tool, depress the on/off switch to “I”.
To stop the tool, depress the on/off switch to “O”.
2. TRIGGER SWITCH (SEE FIG. D)
Depress the on/off switch to “I”, then squeeze the trigger switch to start the spraying work.
3. SELECTING THE SPRAY PATTERNS (SEE FIG. E)
Unscrew the cup nut (9), and turn the air cup (10) to desired position to fit the different
operating conditions. Then re-tighten the cup nut.
Following figure shows the air cup position with their corresponding spraying patterns:
A: Air cup is in horizontal position = the spraying shape is vertical: for vertical surface;
B: Air cup is in vertical position = the spraying shape is horizontal: for horizontal surface;
C: Air cup is in oblique position =the spraying shape is circular: for corners, edges and others.
WARNING! Never turn the air cup when trigger switch is depressed.
4. ADJUSTING THE RATE OF FLOW (SEE FIG. F)
The sprayed capacity can he adjusted by using the flow rate adjusting knob. Adjust the
adjusting knob until the best spray pattern is reached. Turn the adjusting knob clockwise (+)
to increase the flow rate and turn it counter-clockwise (-) to decrease the flow rate. A poor
spray pattern will concentrate the paint in the centre of the spray and give a blotchy finish. A
good spray pattern will give even distribution of paint throughout the pattern.

5. SPRAYING TECHNIQUES
To obtain the best results, keep your spray gun level and parallel to the surface at all times.
Keep the nozzle 5~15cm from the surface and spray evenly from side to side or up and
down, use smooth and even strokes (See Fig. G1).
NOTE:
•Make sure that you have masked the areas that should not be sprayed by a good quality
masking tape.
•The intended area to be sprayed should be pretreated to be smooth and clean, free from
dust.
•Before operating, aim the spray gun at a piece of scrap material and start spraying to
find the best pattern and flow rate.
Do not spray as showing in Fig. G2.
