6.1 Regulation of driving wheel bearings backlash.
After driving the first 100 km and after every 1500-2000 km after that -
check, and if necessary adjust, the backlash of the wheel bearings.
In order to check backlash:

raise the wheel of the spreader intended for backlash adjustment,

by slowly turning the wheel, check whether motion is fluid and the
wheel turns without excessive resistance and jamming - if this is not the
case, replace the bearing,

by gripping the top of the tire with one hand and the bottom of the tire
with the other and deflecting both ends from vertically in an alternating
fashion, check whether the wheel has any noticeable backlash,

if the wheel’s deflection is greater than just barely perceptible, adjust
backlash.
Adjustment of backlash:

dismount the hub cap by levering it out in several places around the
circumference and remove the cotter pin of the castellated nut,
