Tightening nuts
TIP
Wheel nuts should be tightened using a torque of 450 - 510 Nm - nuts M22x1.5.
Nuts should be tightened gradually diagonally, (in several stages, until obtaining the required
tightening torque) using a torque spanner.
Check the wheel nut tightening:
•
After the first use of trailer (one-time inspection).
•
Every 2 – 3 hours of trailer travel (during the first month of trailer use).
•
Every 30 hours of trailer travel.
The above actions should be repeated individually if a wheel has been removed from the
wheel axle.
If a torque spanner is not available, one may use an ordinary spanner. The arm of the
spanner (L), figure (5.4), should be selected according to the weight of the person (F)
tightening the nut. Remember that this method of tightening is not as accurate as the use of a
torque spanner.
