fasteners matched to the cone angle of the wheel. Proper
procedure for attachment of the wheels is as follows:

Start all wheel lug nuts by hand.

1.

Torque all lug nuts in sequence (see Figure 68).

2.

DO

NOT torque the wheel lug nuts all the way down.
Tighten each lug nut in 3 separate passes as defi ned
by Table 15.

After fi rst road use, retorque all lug nuts in sequence.

3.

Check all wheel lug nuts periodically.
