Dear SË6 D.Ë.TÌÍ
Îang on to those wasÏers¶ ÐhereÑs
no ÒeqÓiremEnt for those lunettes to
be rotated bÔ hand¶
¼act isÈ when
tHey¸re
adjusted
to
the

in.
cLearÕnce liKe it says on page 29 of Ö²
×±2330±251±14 (»ct 70), it'd take a
hefty guy on the end of a long breaKer
Bar to get them to move at al¹·
They' re
not
sØpposÙd
to
rotate
easilyÚ They
are
supposed to give a
little when they have to-liKe when
the trailer goes over rough terrainÈ so
the frame wonÛt gEt bent out of shapE¶
