ADJUSTING HASSLE FREE HARNESS™ HEADREST
(with or without side wings)
Correct fitment of the harness is very important as it restrains the child in the restraint. The headrest must
be in the correct position & the harness must fit firmly around upper torso of the child and be positioned so
as to leave the child's arms and legs free.

Adjustment of the headrest automatically adjusts the
harness shoulder strap position. If the headrest has side
wings they should be just above the child's shoulders. If
there are no side wings, the shoulder straps must be in
the slots which are nearest to the child's shoulders, but
not more than 25 mm below the child's shoulders.
Always adjust the height of the headrest, thus the
shoulder straps as the child grows.
If the headrest is in the top position and the shoulders
are above the upper shoulder height marker then the
child is too tall for the restraint and the restraint should
not be used; move to next type of restraint (see pages
23).
NOTE: This child restraint does not require the shoulder
straps to be disconnected to adjust their height, only
the headrest needs to be moved to adjust the shoulder
strap position.
