Danger: re and explosion
Gases volatilized by paint and its solvents can cause
explosions and res. This can lead to property
damage and serious injuries.
Precautions:
• In the work area, exhaust and fresh air must circulate
to prevent ammable gases from accumulating.
• Avoid all ignition sources such as static sparks, open
ames, beacons, hot objects, cigarettes, etc. If you
plug in or unplug the power cord and operatethe
work light switch, it may generate electrical sparks.
• Smoking is prohibited in the spray area.
• Fire extinguishers must be prepared on site
and the re extinguishers are good and effective.
• When working indoors, ensure good ventilation so
that ammable gases can be exhausted timely.
Then the ignition of the combustible gas is avoided by
sparks, which can be generated by the motor of the tool
• When preparing and cleaning components, must follow
the manufacturer's precautions for spraying materials,
solvents, and detergents.
• Do not spray ammable liquids.
• Plastic products are easy to generate static electricity and
it is forbidden toenclose the spray area with plastic products.
Danger: Using unsuitable solvents
can cause an explosion.
The explosion can cause property damage
and serious injury.
Precautions:
• Do not use bleach.

above 130°C may cause explosion.
5. When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws
or other small metal objects, that can make a connection from one terminal to another. Shorting the battery
terminals together may cause burns or a re.
6. Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, ush with water.
If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
7. Use appliances only with specically designated battery packs. Use of any other battery packs may create a risk of injury and re.
8. Do not use a battery pack or appliance that is damaged or modied. Damaged or modied batteries may exhibit
unpredictable behavior resulting in re, explosion or risk of injury.
9. Recharge only with the charger specied by the manufacturer. A charger that is suitable for one type of battery pack may
create a risk of re when used with another battery pack.
10. Follow all charging instructions and do not charge the battery pack or appliance outside of the temperature range
specied in the instructions. Charging improperly or at temperatures outside of the specied range may damage
the battery and increase the risk of re.

Spraying material preparation
Before spraying, the spray material is diluted with the solvent
specified by the material manufacturer. Do not use spray
material that exceeds the specied maximum viscosity.
Follow the below instructions:
1. Thoroughly mix the spray material before checking
the viscosity.
2. Completely immerse the viscosity cup into the spray
material except for the hook part.
3. Lift the viscosity cup and record the time start from cup
up-surface left liquid, in seconds, until the liquid in the
viscous cup has owed. This dripping times are
recommended by materials’ manufacturers.
Below is the viscosity dilute guidline of our tool with
manufature specied viscosity.
4. The spray material need to be ltered with a appropriate
wire mesh before ll in tank to prevent large particle
contaminants get nozzle clogged.
Do not spray ammable liquids.
Filling the spraying material
1. Remove the tank from appliance.
2. Pour the diluted ltered spraying material into the tank.
The liquid level does not exceed the the scale line of
the tank.
3. Carefully screw back the liquid-lled tank onto the gun

Spraying
The HVLP spray gun (High Volume and Low Pressure) is
a brand new spray system for users. Before first spraying,
the user must do some exercises on the discarded wood or
cardboard to conform.
Spraying
Pretreat the surface to be sprayed
The splash result depends on how smooth and clean the
surface is before spraying. Therefore, pretreat the surface
carefully and keep it dust-free. Cover non-spraying areas.
Correct spraying method
• The spray gun be perpendicular to surface when spraying.
Users can choose a distance of nozzle to surface 2-12 inches
depending on the size of the spray pattern. In general, the
longer distance, the bigger spray pattern.
• Gently press trigger by around 4mm for 1~2 second to
blow air ow rst to build up pressure within the
gun. Then press trigger further to generate paint spray.
• Move the spray gun evenly parallel along the application
surface. A consistent spray gun movements result in
a consistent painting quality.
• Generally, spray twice, the rst spraying may be
slightly thinner, and the second spraying should be
slightly thicker.
• At the end of spraying, hold the spray gun far from the
surface to avoid overspray.
Move the spray gun evenly
• Press and hold the trigger while spraying, and release
the trigger when spraying is nished. When spraying the
next layer, align the nozzle with the bottom edge of the
previous sprayed and allow the edges to slightly
overlap for better spray.
