3 With a 14mm and 17mm open wrench tighten the front wheel screws.

2 Slide axle through fork, spacer and wheel hub. When axle passes through the other side of the wheel hub, add the other spacer and slide though the fork. Secure with washer and nut.

Note: Front axle is installed with the spacer between the fork and wheel for all Dirt Rockets.

Note: If your model has one short spacer, it goes on the side of the hub with the disc brake.

Note: where front axle is located in box.

Inflating the Tires

Tires are inflated when shipped, but they invariably lose some pressure between the point of manufacturing and your purchase.

Using a bicycle tire pump equipped for Schrader valves, inflate the tires to the PSI indicated on the sidewall of the tire.

Note: The pressurized air supplies found at gasoline stations are designed to inflate high-volume automobile tires. If you decide to use such an air supply to inflate your tires, first make sure the pressure gauge is working, then use very short bursts to inflate to the correct PSI. If you inadvertently over-inflate the tire, release the excess pressure immediately.
