SAFETY GUIDELINES — TRAILERS
Wheel Rims
If the trailer has been struck, or impacted, on or near the wheels, or if the trailer has struck a curb, inspect the rims for damage (i.e. being out of round); and replace any damaged wheel. Inspect the wheels for damage every year, even if no obvious impact has occurred.
Wheels, Bearings and Lug nuts
A loose, worn or damaged wheel bearing is the most common cause of brakes that grab.
To check wheel bearings, jack trailer and check wheels for
WaRnIng
Lug nuts are prone to loosen after initial installation, which can lead to death or serious injury. Check all wheel lug nuts periodically.
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 K. DO NOT torque the wheel lug nuts all the way down. Tighten each lug nut in 3 separate passes as defi ned by Table C.
NOTICE
neveR use an pneumatic air gun to tighten wheel lug nuts.
3.Check to see if the lug nuts are tight after the fi rst 10, 25 and 50 miles of driving and before each tow thereafter

Lights and Signals
Before each tow, check the trailer taillights, stoplights, turn signals and any clearance lights for proper operation.
Replace any broken or
WaRnIng
Improper operating taillights, stoplights and turn signals can cause collisions.
Check all lights before each tow.
