DANGER
!
To avoid serious injury or death:
•
Do not remove wooden cross-ties and transport chains that
secure wings in the folded position until after harrow is
hooked-up to a tractor, hydraulic hoses are coupled to the
tractor, shipping bands are removed from the spike tooth
harrow sections and shipping bolts are removed from the
trailing chains. The unit can fall suddenly if one or more
wings swing open without notice causing serious bodily
injury or death.
•
Do not remove shipping bolts from trailing chains without
supporting the top bar of the spike tooth harrow sections
with a hoist, fork lift or other suitable lifting device. The
harrow sections can fall 6 to 12 inches suddenly causing
serious bodily injury or death.
•
Never raise the harrow hitch above level with wings folded.
Raising the hitch too high can cause a folded harrow to tip
over backwards resulting in serious bodily injury or death.
CAUTION
!
To avoid minor or moderate injury:
To protect your eyes, face and body, always stand to the side
of a shipping straps being cut and never in line with the straps.
A shipping strap contain built-up energy that is suddenly
released when cut.
