1.
Prior to travel and after excessive braking, wheel lug nuts should be checked for torque.
Torque readings must fall within the Final Torque Values in chart above.
Torque specifications should be checked using a proper torque wrench.
2.
3.
If the torque falls below the Final Torque Values, additional torque is required.
4.
Check and re-torque lug nuts at 10 miles (16 Km), 25 miles (40 Km) and 50 miles (80
Km) and again periodically during travel. Refer to diagrams above for proper lug pat-
tern and Final Torque Values. Thereafter check and maintain torque according to the
Final Torque Values in the chart above.
Failure to follow these instructions may result in wheel loss, an accident, or loss of con-
trol, resulting in death or serious injury.
Lug Nut Pattern and Warning Label
The following labels showing the proper lug nut tightening pattern and a warning label are
located on the driver side of the A frame hitch on travel trailers, and on the driver side of the
pinbox on fifth wheel units. Lug pattern label will vary according to number of wheel lugs.
Torque Wrench Usage
1.
Tools should be maintained, in good condition, and stored appropriately.
•
Avoid dropping or sliding a torque wrench. Dropping it can cause the instrument
to lose reliable calibration.
Damaged tools must not be used and must be removed from service for evaluation
•
and either reported and re-calibrated or replaced.
Do not use accessories or handle extensions unless specifically allowed by the torque
2.
wrench manufacturer.
3.
Do not use the torque wrench as the primary means of tightening or loosening fasteners.
Torque wrenches are length specific.
4.
•
Grasp the torque wrench in the center of the handle when applying torque pres-
sure.
•
Place one hand on top of the other when using two hands.
5.
Apply torque in a slow, steady manner in a downward direction and avoid sudden
"jerking" movements.
When the wrench signals (by clicking, beeping or lights) that a specific torque has been
6.
reached, stop immediately.
Tires
Read and understand the following before taking your first trip in your RV.
Routine maintenance on your RV is important. To ensure your tires are operating safely,
regular inspection of the tires and checking tire pressures is absolutely mandatory.
Alignment, balance and bearing wear will affect tire wear. Make sure to look for cracking,
bulging, uneven tread wear, etc.
