WHEEL DISMOUNTING
• Before lifting the wheel to be dis-
mounted, loosen wheel nuts ac-
cording to the sequence shown in the
figure.
• Place the wheel chocks under the
wheel opposite to the wheel to be
dismounted.
• Place the lifting jack under the axle
backing, between the U bolts.
• Raise the trailer to a sufficient height
so that the wheel to be replaced does
not touch the ground.
• The lifting jack should have sufficient
lifting capacity and should be techni-
cally reliable.
• The lifting jack must be positioned
on a level and hard surface so as to
prevent sinking into the ground or re-
locating the jack during lifting.
• If necessary, use proper backing
plates in order to reduce unit pressure
of the jack's base on the ground and
prevent its sinking into the ground.
• Dismount the wheel.
WHEEL MOUNTING
