TM 9-243
USING A RATCHET LEVER JACK
1
The operator should familiarize himself with the
jack, its capabilities and its operations. The
reversing lever (1) is located below the lifting
mechanism cover (2) on the left side of jack when
viewed from the lifting lever. When preparing to lift
a load, the head (3) can be pulled up by hand to
meet the load.
2
To raise a load, pull reversing lever up and toward
the operator and operate the lever (4). The jack will
raise the load one notch for each lever down stroke.
The rack (5) cannot be ratcheted out of the base, as it is
designed to stop when raised to its top limit.
3
To lower a load, push reversing lever to straight
down position and operate the lever. The jack will
lower the load one notch for each upstroke of the
lever.
4
When the head of the five-ton jack is not supporting
a load, the rack can be allowed to fall free by
pressing the reversing lever all the way to the rear
and slightly lifting up on the lifting lever. The rack
will not fall free if even a slight load is still on the
head.
