You can combine your pens to get more color combinations. For example, you can get green by applying blue and yellow inks over each other. First apply a thin layer of one color until you get the desired coverage, then switch pens and apply an even layer of your second ink. Try making your own combinations!

First insert the flexible stencils into the frame with the built-in peg fitting. Connect the frame onto the four posts on top of the car decoration turntable, and then adjust the height of the frame for tall and low cars by using the two detent locations. Remember that in order to spray using stencil, the airbrush must face directly down over the top of the car and spray through the stencil.

Use the circular stencil tool to add detail to your artwork. First fully insert the pen until you hear/feel it click and adjust the spray nozzle until you get a nice even spray. Then plug the circular stencil tool directly onto the end of the airbrush tip. Rotate the stencil to select the artwork that you would like to apply. The art should be centered over the spray tip and applied to the car in close range.

• If you hear “Error,” ask an adult to unplug Car Maker from the wall, wait ten seconds and then plug it back in to reset. Car Maker may automatically go into the cooling cycle. Do not unplug during this time. If you continue to hear “Error” after multiple resets, this may be an indication of a mechanical problem with the door switch; please contact Consumer Services via service.mattel.com for assistance.

On the underside of the launcher, each end of the rubber band should be wrapped around a peg on each side of the main launcher and then doubled up and hooked around the center tab of the moveable portion of the launcher.

Here is a picture of an assembled rubber band launcher!

After you’ve airbrushed your car, lower the turntable into the drying chamber by turning the handle on the far right counterclockwise toward the ground. Rotate the knob outside the chamber all the way to the rightmost setting to turn the fan on. Air will blow inside the drying chamber and dry off your car!

• The very first time you use Car Maker, you need to insert 2 wax sticks. Car Maker comes pre-loaded with 1 wax stick. The second stick you insert is not meant to fit completely inside the machine – it will protrude through the top. After you have made your very first car, only 1 additional wax stick needs to be inserted every time. Please note that ALL wax sticks must be inserted with the point side down.

• Yes, for best results, allow the wax to cool for a few minutes before opening the mold. Twist the mold slightly (as you would an ice cube tray) to break the wax free. You can also run the mold under cold water, which will help speed up the cooling process. If the car body is wet, be sure to dry it completely before applying labels. Remove car body from the mold within 10 minutes. If the body is left in the mold for any longer, the wax may begin to crack.

Push the handle on the far right counterclockwise all the way to the ground and the car platform will tip forward, allowing your car to roll out.

You can, but the adhesive should be applied to a clean, smooth, dry surface when the temperature is above 50°F (10°C). If the temperature is below 50°F, you can heat the surface with a hair dryer before application.

• If you cannot press the handle down, have an adult unplug the machine, wait ten seconds and then plug it back in to reset. Car Maker will automatically go into the cooling cycle. Do not unplug during this time. After you hear “Cooling Complete” and the door opens, try the following:
• Check the mold for blockage. See CLEANING section in the instruction sheet.
• Look into the front window on the machine. Ensure that there is a wax stick in the heating chamber and that the wax stick above it is properly aligned.

• DO NOT start injecting wax until Car Maker prompts you to “Please pull down handle.” If you start the injection before this, it can cause blockage in the mold. Blockage can be cleared using the included tool (see CLEANING section in the instruction sheet).

• Excess wax on the car body can be easily trimmed by hand or with the supplied design tool.

• If you have inserted different colored wax sticks next to each other, you may get some color blending (in which the wax from the two adjacent sticks mix when creating the car body).

You need to fine tune the spray nozzle by turning the adjustment nozzle all the way to the negative side (-). Then while holding the trigger down, slowly adjust the nozzle toward the positive side (+) until you get a nice even spray. You should also make sure that the pen is fully inserted by pushing it all the way into the slot on the spray gun until you hear/feel it click.

You should hear/feel it click when you push the pen down into its slot on the spray gun.

• If your car body came out only partially completed, see instructional video or try the following:
• Ensure you are inserting enough wax sticks into the machine and they are positioned next to each other in the proper alignment (point side down).  Remember, it’s normal for one of the wax sticks to protrude from the top.
• Ensure the handle is pulled all the way down in one continuous motion and the injection is completed within 2-3 seconds until you hear “Complete.”

• Ensure the mold has been thoroughly cleaned before starting your cycle.
