Lug Nut Torque Requirements
It is extremely important to apply and maintain proper wheel
mounting torque on the trailer. Be sure to use only the
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 3. DO NOT
torque the wheel lug nuts all the way down. Tighten
each lug nut in 3 separate passes as defined by Table 4.
3. After first road use, retorque all lug nuts in sequence.
Check all wheel lug nuts periodically.
NOTE
NEVER use an pneumatic air gun to
tighten wheel lug nuts.
