4.7 “L” ARM GRID OPERATION
1. Set the grid width as required for
the casualty vehicle to be towed.
"T" HANDLE
2. To set the grid width, loosen
the “T” handles on the front of
the grid arms and pull out. Be
sure both grids are as close
to the center of the boom as
possible, and wide enough to
allow the L-Arms to slide into
their channels. Tighten the “T”
handles to secure the grids.
3. Retract the “Cam” handle locking
pin on the grid by turning it 180°.
It should remain in the open
position.
4. Extend the lift arm under the
casualty vehicle. Make sure
that all under carriage parts are
cleared and that the front portion
of the grid is in contact with both
tires. Lower the grid fully to the
ground.
There is no reason for the
operator to get under the
casualty vehicle.
