To release the spare wheel, loosen
cable by connecting the wheel
wrench and adapters (depending on
vehicle) to the slot position illustrated
and lower the wheel fully by turning
wrench clockwise.
Caution
Only use the wheel wrench and
adapters (depending on vehicle)
to lower the spare wheel.
The use of pneumatic tools is
prohibited. This may result in
damage to the winch cable and
equipment.
Place wheel upright, unclip retainer
from wheel rim and release the wheel
from the cable and connected
retainer by routing these components through the centre of the wheel.
Twin rear wheel vehicles have an
additional mounting plate attached to
the spare wheel. Before using the
wheel, undo the nut and remove the
mounting plate.When reinstalling a spare wheel, first
attach the mounting plate (twin rear
wheel vehicles) and secure with the
nut.
Place wheel upright, then route the
cable and connected retainer from
the front of the wheel (side with tyre
valve) and through the centre of the
wheel. Attach the retainer and clip it
into place, ensuring it is correctly
positioned and that the front of the
wheel (side with tyre valve) will be
facing upwards when reinstalled.
