1. Rotate the gap gauge until it is perpendicular to the body
of the tool. Tighten the screw. The gap gauge can
permanently remain in this position unless you wish to store
the tool in the zip lock bag. |

2. Turn the car over and place the tool on the bottom of the
car with the ridge in the axle slot and the gap gauge snug against
the car body. If your car has shallow axle slots, turn
the tool over so the flat side is against the bottom of the
car. |

3. Mount the wheel on the axle and insert the axle partially
into the slot holding the tool firmly against the bottom of
the car. NOTE: the above picture shows the axle without the
wheel for illustration.. |

4. Place the wheel head on a hard surface. Firmly hold the tool
to the block and apply downward pressure on the axle. Continue
until the axle will go no further. |

5. Use your thumb or the handle of a small screwdriver to push
the axle in until the wheel is snug against the gap gauge. |
6. Carefully remove the tool and repeat for the other axles. |
