or crack the air hose. Gently coil the hose and either hang on a hook
or fasten with a device to keep hose together when storing.
4. A damaged or disconnected air hose under pressure may whip around and
inict personal injury or damage the work area. Secure the compressor's
air hose to a xed or permanent structure with clamps or cable ties.
ELECTRICAL SAFETY
WARNING! Do not touch or handle a live tool with any part of your body
that is wet or damp. Wet skin reduces resistance to electrical current,
increasing the danger of a serious or fatal shock.
1. Do not alter any parts of the tool or accessories. All parts and accessories
are designed with built-in safety features that may be compromised if
altered.
2. Protect yourself against electric shocks when working on electrical
equipment. Avoid body contact with grounded surfaces. There is an
increased chance of electrical shock if your body is grounded.
3. Do not expose the spray gun to rain, snow, frost or any other damp or wet
conditions. Water entering a tool will increase the risk of electric shock.
4. Do not disconnect the power cord in place of using the power switch. This
will prevent an accidental start-up when the power cord is plugged into
the power supply.
5. In the event of a power failure, turn o or unplug the machine as soon as
the power is interrupted. The possibility of accidental injury could occur if
the power returns and the unit is not switched o.

Page 7 www.princessauto.com / 1-800-665-8685

6. Make certain the power source conforms to requirements of your
equipment (see Specications).
7. A polarized plug has two blades of dierent widths, allowing only one
way to insert the plug into the outlet. If the outlet does not accept a
polarized plug, contact a qualied electrician to install a polarized outlet.
Do not alter the plug, as this may compromise the built-in safety feature.
POWER TOOL PRECAUTIONS
1. Do not use any power tool with a malfunctioning power switch or control.
A power tool that fails to respond to the controls is dangerous and can
cause an injury. A qualied technician must repair and verify the power
tool is operating correctly, before it can be used.
2. Shut the power o and disconnect the spray gun from the power supply
(if possible) before making any adjustments, changing accessories,
cleaning, servicing or when storing. Such preventive safety measures
reduce the risk of starting the tool accidentally.
3. Never force the spray gun. Excessive pressure could break the tool,
resulting in damage to your workpiece or serious personal injury.
Excessive pressure is the cause if your tool runs smoothly under no load,
but roughly under load.
4. Check if the spray gun's moving parts are misaligned or binding before
each use. Correct the issue before using the spray gun to avoid an injury
or damage to the tool.
5. The material and the motor housing can get very hot during operation.
Stop work until the spray gun and the spray nozzle both cool down to a
safe temperature.
6. Do not cover the air vents. Proper cooling of the motor is necessary to
ensure normal life of the tool.
7. Avoid unintentional starts. Be sure that the regulator/throttle switch is in
the neutral or OFF position when not in use and before connecting it to
any air source.
8. Avoid unintentional starts. Make sure the power switch is set to OFF
before connecting the spray gun to a power supply.

ADJUST THE SPRAY GUN
The HVLP spray gun has three dierent spray patterns.
Select the pattern by changing the air cap's angle.
1. Adjust the air cap so the ridges are horizontal in
relation to the spray gun body. This will create a
vertical, oval spray pattern.
2. Adjust the air cap so the ridges are vertical in relation
to the spray gun body. This will create a horizontal,
oval spray pattern.
3. Ajust the air cap so it is at a 45° angle in relation to the
spray gun body. This will create a round spray pattern.
4. Adjust the amount of material that is sprayed by
turning the uid adjustment knob.
a. For more material, turn the knob to the right.
b. For less material, turn the knob to the left.
MEASURING PAINT VISCOSITY
Paints come in a variety of viscosities and may require dilution to obtain the
best spraying results, as the paint is normally made for brush or roller
applications.
1. Pour the paint or lacquer into a bucket or other container.
2. Consult the Paint/Solvent Ratio
table and add a solvent
appropriate for the paint/
lacquer. Check the
manufacturer’s label for the
specic type of thinner
required. The ratios are
approximate.
3. Stir to mix the paint and
thinner.
4. Fill the included measuring cup with the paint mixture and pour it back
into the container. The mixture is thin enough when it takes 8 to 20
seconds to empty the cup.

5. Add more thinner if the mixture is too thick or paint if the mixture is too
thin. Repeat steps 3 and 4 until you are satised with the thickness.
6. Stir the thinned-paint each time before relling the paint cup. Remove
lumps or a 'surface skin' by straining the paint mixture through
cheesecloth, nylon stocking material or a commercial paint strainer with a
60-mesh.
