Section 6
6.1 WHEEL MOUNTING AND DISMOUNTING
REMOVE WHEEL
• Immobilise trailer with parking brake.
• Place the wheel chocks under the
wheel opposite to the dismounted
wheel.
• Ensure that trailer is immobilised
when wheel is being removed.
• Loosen wheel nuts according to the
sequence shown in figure (6.1).
• Place a lifting jack and 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 technically reliable. The lifting jack
must be positioned on a level and
hard surface so as to prevent sinking
into the ground or relocating 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 wheel.
