DANGER
!
To avoid serious injury or death:
•
Make adjustments to the implement after it has been
properly attached to a tractor and secured with solid non-
concrete supports in the up position. Never work around or
under equipment supported by hydraulics. Hydraulics can
drop equipment instantly if controls are actuated or if
hydraulic lines burst even when power to hydraulics is shut
•
Always keep your feet and legs out from under the shanks
while adjusting them. It is possible for the shanks to fall
causing injury to your feet and/or legs.
