Releasing A Load
1.
Be sure to read and understand all safety alerts
under
2.
Stop in front of desired location.
3.
Slowly raise load to required height and move
forward slowly checking to make sure grapple and
load clears all obstacles.
4.
Stop forward movement when load is positioned over
its release location.
5.
Releasing load requires a combination of tilting front
of grapple down, raising upper jaws, and raising
loader arms. The order in which the load is released
will vary depending on type of material being
released. The most important objective is to have the
load under control throughout the release.
6.
Once load has settled onto the pile, slowly back up
making sure grapple clears all objects and there are
not any pedestrians or other traffic behind or on
either side.
7.
Leave enough clearance when turning and/or
lowering grapple to avoid contact with obstacles such
as vehicles, buildings, trees, fences, etc.
8.
Lower grapple to transporting height (low to the
ground) before moving again.
