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 fas-
teners matched to the cone angle of the wheel. Proper pro-
cedure 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 30. DO NOT
torque the wheel lug nuts all the way down. Tighten each lug
nut in 3 separate passes as defined by Table 10.
3. After first road use, retorque all lug nuts in sequence. Check
all wheel lug nuts periodically.
NEVER!
use an pneumatic air gun
to tighten wheel lug nuts.
