It is extremely important to apply and maintain proper wheel

fasteners matched to the cone angle of the wheel. Proper

procedure for attachment of the wheels is as follows:
1. Start all wheel lug nuts by hand.
2. Torque all lug nuts in sequence (see Figure 61).

Do

noT torque the wheel lug nuts all the way down.

Tighten each lug nut in 3 separate passes as defined

by Table 18.

3. After first road use, retorque all lug nuts in sequence.

Check all wheel lug nuts periodically.
