FIG. 5.3

Sequence of nut tightening

(1) - (6) sequence of nut tightening, (L) spanner length, (F) user weight

Checking wheel half axle tightening:

•

after first use,

•

after first day of work,

•

at regular intervals (50 h).

The inspection should be repeated individually if a wheel has been removed from the
wheel axle.

ATTENTION

Axle nuts may not be tightened with impact wrench, because of danger of exceeding
permissible tightening torque, the consequence of which may be breaking the thread
connection or breaking off the hub pins.

The greatest precision is achieved using a torque spanner. Before commencing work,
ensure that correct tightening torque value is set.
